JUSTIFYING FIDUCIARY DUTIES

Paul B. Miller*

Fiduciary duties are critical to the integri-
ty of a remarkable variety of relationships, in-
cluding those between trustee and beneficiary,
director and corporation, agent and principal,
lawyer and client, doctor and patient, parent
and child, and guardian and ward. Notwith-
standing their variety, all fiduciary relation-
ships are presumed to enjoy common character-
istics and to attract a core set of demanding le-
gal duties, most notably a duty of loyalty. Sur-
prisingly, however, the justification for fiduciary
duties is an enigma in private law theory. It is
unclear what makes a relationship fiduciary
and why fiduciary relationships attract fiduci-
ary duties. This article takes up the enigma. It
assesses leading reductivist and instrumental-
ist analyses of the justification for fiduciary du-
ties. Finding them wanting, it offers an alterna-
tive account of the juridical justification for fi-
duciary duties. The author contends that the fi-
duciary relationship is a distinctive kind of legal
relationship in which one person (the fiduciary)
exercises power over practical interests of an-
other (the beneficiary). Fiduciary power is a
form of authority derived from the legal capaci-
ty of the beneficiary or a benefactor. The duty of
loyalty is justified on the basis that it secures
the exclusivity of the beneficiarys claim over fi-
duciary power so understood.

ciaire est un type de rapport juridique particu-

exerce un pouvoir sur les intrts pratiques
dune autre personne (le bnficiaire). Le pou-

de la capacit juridique du bnficiaire ou dun

JUSTIFYING FIDUCIARY DUTIES 971

Introduction
Fiduciary duties are critical to the integrity of a remarkably wide va-

riety of relationships and institutions.1 Lawyers, doctors, investment ad-
visors, and other professionals are fiduciaries of their clients. Trustees,
executors, and agents are fiduciaries of their beneficiaries, testators, and
principals. Directors, officers, and trustees of corporations, hospitals, uni-
versities, and charities are fiduciaries of the legal entities under their
charge. Parents and guardians are fiduciaries of their children and wards.
These relationships and institutions are obviously of profound social and
economic importance. Professional fiduciaries have charge of critical per-
sonal interests of their clients. Trustees have responsibility for great for-
tunes settled on trust for donative and commercial purposes. Directors
and officers of non-profit and business corporations determine the disposi-
tion of vast amounts of wealth for charitable and commercial purposes.
Parents and guardians determine most of what matters to the well-being
of children and incapable adults.
Clearly, fiduciary duties are pervasive in modern civil society. Wheth-
er we are aware of it or not, virtually all of us have, in our lives or upon
our deaths, interests subject to the discretion of a fiduciary. In most cases,
where we rely on another person to represent us or to take care of our
person or property, we do so within a fiduciary relationship. Fiduciary
law, as much as contract, property, or tort law, is a dominant mode of im-
posing legal structure on day-to-day life.

The mandates under which fiduciaries act differ widely across categories
of fiduciary relationship. However, despite the diversity of factual scenarios
in which fiduciary duties arise, these relationships share a set of legal prin-
ciples common to all fiduciary relationships. Furthermore, all fiduciary rela-
tionships attract the consequences attached by law to this kind. The conse-
quences are several.2 Most prominent is the asymmetrical assignment of le-

gal duties between the parties, notably the distinctive duty of loyalty.3 All fi-
duciaries are, by virtue of this duty of loyalty, subject to exacting expecta-
tions of faithful service. Fiduciaries are expected only to pursue the interests
of beneficiaries when executing a fiduciary mandate. To that end, the duty of
loyalty strictly forbids conflicts of interest and conflicts of duty, on pain of
powerful remedies that strip fiduciaries of any gains realized in breach.4

Surprisingly, given their importance, we know relatively little about
the justification for fiduciary duties. Philosophers have generated im-
portant accounts of the justification for liability in tort, contract, property,
and unjust enrichment.5 However, they have been virtually silent on fidu-
ciary duties.6

JUSTIFYING FIDUCIARY DUTIES 973

Claims that have been made about the justification for fiduciary du-
ties reflect two analytical strategies. Reductivists allege that fiduciary du-
ties are derivable from nonfiduciary forms of private liability (e.g., con-
tract or tort). Reductivists assert that the justification for fiduciary duties,
as a secondary form of liability, is the same as that of the primary nonfi-
duciary form of liability. Instrumentalists, by contrast, claim that fiduci-
ary duties are directly justifiable on the basis of some independently-
valuable end (e.g., a policy goal or moral norm). Most reductivist and in-
strumentalist argument capitalizes on important insights about the jurid-
ical character of fiduciary liability. However, for reasons that I will devel-
op below, these arguments are ultimately unsound. This article thus of-
fers a novel account of the juridical justification for fiduciary duties.

Juridical justificatory argument aims to reveal the justificatory struc-
ture of the settled practices and principles of liability constitutive of a giv-
en legal form of an institution or mode of interaction (e.g., the idea of
ownership, contract, gift, or treaty). As I shall explain, it is different from,
but has certain affinities with, Weinribs formalism and Zipurskys prag-
matic conceptualism.7 The juridical justification for fiduciary duties con-
tends that formal characteristics of the fiduciary relationship support fi-
duciary duties in all circumstances in which fiduciary duties arise.

The argument will unfold as follows. Part I explains the nature of the
problem of justification. Part II offers a thin description of the juridical
character of fiduciary liability, making stipulations necessary to motivate
the critical and constructive contributions of the article. Parts III and IV
critically assess leading claims about the justification for fiduciary duties
and emphasize insights about the juridical character of fiduciary liability
that they afford. Collation of these insights permits the development of a
thicker description of the juridical character of fiduciary liability. Part V
advances this description as well as the novel juridical justification for fi-
duciary duties.

I. The Problem of Justification
Many private law theorists, economists and doctrinalists in particular,
claim only descriptive ambitions for their work. Doctrinalists aim to clari-
fy the operation of principles of private liability, to analyze actual or ap-
parent doctrinal problems (ambiguities in, or inconsistencies or gaps be-
tween, legal principles), and to suggest ways in which these problems may
be resolved in a manner consistent with logic and precedent.8 Economists
aim to explain private law, not (or not principally) in its own terms, but
rather in terms of its general economic context or impact on any of a
number of measures of economic welfare (e.g., efficiency in respect of so-
cial costs, transaction costs, or information costs).9
While much of private law theory is concerned with descriptive prob-
lems of explanation and classification, much of it is also given over to the
normative problem of justification. The problem of justification has many
variants, but all are ultimately concerned with the normative coherence
of, and foundations for, private law. Historically, normative private law
theory has been the ken of philosophical theorists.10

The distinctions between problems of justification, on the one hand,
and explanation and classification, on the other, are not neat. Doctrinal-
ists sometimes address the justification for legal principles, particularly
when offering a novel interpretation or recommending that principles be
amended or extended in a way not clearly supported by precedent. Econ-
omists are well-known for combining descriptive with normative argu-
ment; indeed, some have been criticized for a tendency to make normative
claims in the guise of explanatory statements.11 And most philosophers
are aware that justificatory argument about law must accurately account
for its posited character. Inevitably then, efforts to explain and justify law
become intertwined. An implication is that there is no monopoly on nor-
mative argument in private law theory.

JUSTIFYING FIDUCIARY DUTIES 975

The problem of justifying fiduciary duties does not differ from that of
justifying other kinds of private law duties. In each case, the challenge is
one of identifying a normative basis for the duty. To qualify as a justifica-
tory claim, an argument must articulate reasons for the imposition and
enforcement of fiduciary duties. As is well-known, law has both positive
and normative aspects; it is authoritatively articulated, and insofar as it
purports to direct conduct, it makes a claim of obedience that stands in
need of justification. Justificatory analyses accordingly may be evaluated
for normative and descriptive merit.
Normative merit entails that the reasons given for the duty are good;
that is, that they offer sufficient logical support for its content and any
conditions on its imposition and enforcement. I take it that a justificatory
argument need not be exhaustive or exclusive in the set of reasons offered
in support of a duty in order to have normative merit. A given reason or
set of reasons may have normative merit but be capable of supplementa-
tion by additional supporting reasons or broader normative argument
(e.g., about the justification for any system of private liability or the vari-
ous forms such a system might take).
Descriptive merit requires that the reasons said to support the obliga-
tion demonstrate a reasonable degree of fit or conformity with the positive
law. Where the obligation is juridical (as is the case for common law and
equitable obligations), fit is a function of the capacity of the reasons given
to explain the juridical character of the obligation. As I will explain in
Part V, juridical character is expressed in judicial reasoning on the basis,
content, scope, and limits of the obligation.

II. The Range, Content, and Basis of Fiduciary Duties
Before analyzing the justification for fiduciary duties, we must regis-
ter some stipulations about the positive law. As noted above, justificatory
analysis is impossible without some agreement on the subject matter; in
this case, basic elements of the juridical character of fiduciary liability, in-
cluding the duties considered fiduciary as well as their content and
source. There is significant disagreement on aspects of the juridical char-
acter of fiduciary liability. However, there is sufficient consensus on basic
aspects to motivate and orient our analysis.
As to the range of fiduciary duties, there is doubt over the status of
several duties often said to be fiduciary.12 For instance, it is uncertain

12 See Julian Velasco, How Many Fiduciary Duties Are There in Corporate Law? (2010)

976

whether the duty of confidence that governs the handling and use of con-
fidential information by fiduciaries is properly considered a fiduciary du-
ty.13 It is likewise unclear whether the duty of care, which requires fiduci-
aries to act reasonably in fulfilling their mandates, is a fiduciary duty.14 It
has also been controversially suggested that fiduciaries are subject to a
positive duty to act in the interests of beneficiaries.15

The boundaries of fiduciary obligation are poorly defined, but there is
consensus on its essence. At the core lies the cardinal fiduciary duty of
loyalty.16 Whatever else fiduciary law might require of fiduciaries, it un-
deniably demands that they act faithfully toward beneficiaries. The duty
of loyalty applies to all fiduciaries regardless of differences among the

and commentary: see Ray D Madoff, Unmasking Undue Influence (1997) 81:3 Minn L
Rev 571 ([c]onfidential relationships can be understood as both a form and an exten-
sion of fiduciary relationships at 583). For an opposing perspective, see John Glover,

the fiduciary position … These two principles are widely recognised as being of univer-
sal application to fiduciaries at 39).

JUSTIFYING FIDUCIARY DUTIES 977

mandates under which they act.17 Indeed, it is the universal applicability
of the duty in the face of marked factual differences among fiduciary
mandates that underscores the importance of the problem of justification
in fiduciary law theory. Accordingly, for present purposes, I focus exclu-
sively upon the justification for the duty of loyalty.
While there is broad agreement that the duty of loyalty is distinctively
fiduciary, there is some disagreement over its content. It is widely accept-
ed that the duty of loyalty prohibits fiduciaries from acting under conflicts
of interest.18 This prohibition is usually expressed in the form of two rules.
The conflict of interest rule prohibits the fiduciary from allowing personal
interests actually or potentially to conflict with the interests of the benefi-
ciary.19 The conflict of interest rule thus prohibits disloyal conduct
grounded in the self-interest of the fiduciary. The conflict of duty rule pro-
hibits the fiduciary from acting under conflicting mandates.20 In other
words, it prohibits disloyal conduct grounded in conflicting duties to two
third parties, even if the fiduciarys self-interest is not in play. The conflict
of duty rule thus proscribes disloyal conduct rooted in inconsistent alle-
giances of the fiduciary.

17 As noted by Seavey, The duties of loyalty are substantially the same for all fiduciaries,
varying only in intensity (Warren A Seavey, Handbook of the Law of Agency (St Paul,
Minn: West, 1964) at 4). See also Restatement (Third) of Trusts 2, comment b (2003)
([d]espite the differences in the legal circumstances and responsibilities of various fi-
duciaries, one characteristic is common to all: a person in a fiduciary relationship to an-
other is under a duty to act for the benefit of the other as to matters within the scope of
the relationship).

18 See Birnbaum v Birnbaum, 539 NE (2d) 574, 541 NYS (2d) 746, (1989) [Birnbaum cited
to NE (2d)] (a fiduciary owes a duty of undivided and undiluted loyalty to those whose
interests the fiduciary is to protect … requiring avoidance of situations in which a fidu-
ciarys personal interest possibly conflicts with the interest of those owed a fiduciary du-
ty at 576).

It is debatable whether there is anything else to the duty of loyalty.
Some have argued that it includes a requirement of good faith.21 But it is
unclear what this obligation requires of the fiduciary and how it relates to
the substance of the duty of loyalty.22 Equally contentious is the question
whether the duty of loyalty includes an independent rule prohibiting re-
ceipt of profits by fiduciaries under a fiduciary mandate.23 The so-called no
profit rule is ordinarily expressed as requiring the fiduciary to disgorge all
profits received by virtue of a fiduciary office or position.24 There is ample
authority for the proposition that the rule exists and is enforceable as
such. Nevertheless, it has been doubted that the rule is independent of
the duty of loyalty.25 Fortunately, for present purposes, it is of no conse-
quence whether the duty of loyalty encompasses independent no profit
and good faith requirements. It has minimum core content consisting of
the conflict rules. Meaningful progress on the problem of justifying the
duty of loyalty may be had in accounting for these rules.

Less scholarly attention has been paid to the basis of fiduciary duties.
Fortunately, the authorities are clearer on this question. The conventional
position is that fiduciary duties arise upon the establishment of a fiduci-
ary relationship. The analytical priority of relationship to duty is reflected
in many canonical statements of Commonwealth law.26 American law is

25 The obligation to act disinterestedly is often put as an obligation not to profit from the
trust. When we ask which profits are interdicted, in nearly every case the answer is
given by the rule against conflicts of interest (Birks, Content of Obligation, supra

not explain the connection between relationship and duty. This, in turn,
requires that one have a clear concept of the fiduciary relationship.
Having identified the extent of consensus on the juridical character of
fiduciary liability, we are now able to formulate the problem of justifica-
tion more precisely. The problem lies in explaining why fiduciary relation-
ships generate a duty that (at the very least) implies that the fiduciary is
to act solely in the interests of the beneficiary, and prohibits her from act-
ing in self-interest or for third parties with conflicting interests.

III. Reductivist Justifications
One of the two dominant analytical strategies for dealing with this
problem is characterized by reductivist reasoning. Reductivists claim that
fiduciary duties are not distinctive but are rather derived from other ba-
ses of private liability.

A. The Argument from Contract

The most prominent reductivist argument is that from contract. This
argument holds that fiduciary duties are justified just as ordinary con-
tractual obligations are. There are two variants on the argument. The
first provides that fiduciary duties have contractual justification because
they are properly understood as contractual terms. The second holds that
fiduciary duties have contractual justification in that they are founded on
consent.

The argument from contract is rooted in three insights about fiduciary
liability. The first is that fiduciary duties typically arise in relationships
that are contractual or are otherwise voluntarily entered into by the fidu-
ciary. The second is that fiduciary duties frequently constrain the perfor-
mance of contractual undertakings. The third is that the application or ef-
fect of fiduciary duties, or extent of liability for breach, may be partially
determined by mutual consent. These features of fiduciary liability are
thought to suggest that fiduciary duties have contractual justification.29

Frank Easterbrook and Daniel Fischel have advanced the best-known
version of the first variant on the argument from contract.30 Noting the

29 As Victor Brudney explains, It is the power thus to authorize (or consent to) departure
from the exclusive benefit principle (coupled with the initial consent to enter into the re-
lationship) that is said to establish that the fiduciary relationship is simply a species of
contract (Contract and Fiduciary Duty (1997) 38:4 BCL Rev 595 at 605 [Brudney,
Contract and Fiduciary Duty]).

absence of a convincing theory of fiduciary duties that treats them as dis-
tinctive, they start with an inferential leap to the conclusion that they are
not:

JUSTIFYING FIDUCIARY DUTIES 981

Scholars of non- or antieconomic bent have had trouble coming
up with a unifying approach to fiduciary duties because they are
looking for the wrong things. They are looking for something special
about fiduciary relations. There is nothing special to find. … [T]here
is no subject here, and efforts to unify it on a ground that presumes
its distinctiveness are doomed.31

Easterbrook and Fischel claim that fiduciary duties should instead be
understood as implied terms of contract. More particularly, the duty of
loyalty is an implied term of relational service contracts in which exper-
tise is hired by a nonexpert. The implied term is required where complete
contractual specification of terms would be impossible or inefficient. They
explain:

One party to the contract may desire an objective (maximum income
from an investment, a favorable outcome to litigation) but have nei-
ther an idea nor much concern how the objective is to be achieved.
Specialists in achieving this objective (trustees, managers, lawyers)
agree to lend their efforts. When the task is complex, when efforts
will span a substantial time, when the principal cannot measure (or
evaluate) the agents effort, when an assessment of the outcome is
not a good substitute for measuring effort … and when a relative
shortage of information hinders the drawing of conclusions even
when the outcome may be highly informative, a detailed contract
would be silly.32

The content of fiduciary duties is said to reflect exigencies of relational
service contracts involving the hiring of expertise. In such contracts, the
nonexpert faces agency costsdue to shirking and self-dealing
associated with delegation to the expert. Fiduciary duties protect against
these costs:

When one party hires the others knowledge and expertise, there is
not much they can write down. Instead of specific undertakings, the
agent assumes a duty of loyalty in pursuit of the objective and a duty
of care in performance. These legal duties reflect both the nature of
the principals choice (he is hiring expertise) and an obvious condi-
tion (the principal is unwilling to put himself at the mercy of an

agent whose effort and achievements are both exceedingly hard to
monitor).33

Easterbrook and Fischel contend that courts are justified in recogniz-
ing fiduciary duties not on the basis of the actual common intent of the
parties but instead on the basis of a hypothetical bargain. According to
Easterbrook and Fischel, [C]ourts flesh out the duty of loyalty by pre-
scribing the actions the parties themselves would have preferred if bar-
gaining were cheap and all promises fully enforced.34 They conclude that
fiduciary duties are not special duties … [instead] they are the same sort
of obligations, derived and enforced in the same way, as other contractual
undertakings.35
Easterbrook and Fischels argument has generated significant criti-
cism.36 Accepting the insights on which it is based, it is still deeply flawed.
Let us consider first its descriptive failings.

First, the argument fails properly to account for the formation of fidu-
ciary relationships. Many, but not all, fiduciary relationships are estab-
lished through contract. Fiduciary relationships may alternatively be es-
tablished by non-contractual agreement, by unilateral undertaking, or by
legislative or judicial decree.37 An argument from contract law cannot ac-
count for fiduciary duties generated by relationships established other
than by contract.

Second, the argument does not accurately describe the nature of the
fiduciary relationship. Some, but not all, fiduciary relationships involve
the engagement of an expert by a nonexpert. Expertise is not a de jure or
de facto qualification of fiduciaries.38 Furthermore, one expert may hire

ness transaction at 1280 [references omitted]). In the trust law context, trustees are of-

JUSTIFYING FIDUCIARY DUTIES 983

another without their shared or similar levels of expertise being consid-
ered inconsistent with the fiduciary nature of their relationship.39 The hir-
ing of expertise is therefore not the sine qua non of the fiduciary relation-
ship.

Third, the argument does not account well for the content of fiduciary
duties. If the duty of loyalty really were an implied contractual term, one
would expect its content and application to turn on material facts (other
terms, the expectations of the parties, representations made by the par-
ties, and industry practice). Instead, the core content of the duty of loyalty
is fixed, and the duty applies wherever a fiduciary relationship exists.40

Finally, the argument is inconsistent with judicial practice. In decid-
ing whether fiduciary duties should govern a particular relationship,
courts do not generally engage in construction of contracts. Rather, they
determine directly whether a relationship is fiduciary. The imposition of
fiduciary duties follows from that determination and is not mediated by
explicit or implicit contractual terms.
Easterbrook and Fischels argument is also normatively unsatisfying.
First, it fails to account for a deep inconsistency in presuppositions about
the rightful conduct of people in contractual and fiduciary relationships,
respectively. In contract it is assumed that the parties will act in a mutu-
ally self-interested manner. Each is responsible for securing their inter-
ests in dealings with the other. In fiduciary law, by contrast, it is assumed
that the parties are interacting for the exclusive benefit of one of them
the beneficiary.41 The fiduciary is responsible for the beneficiary. The ben-
eficiary is entitled to the fiduciarys loyalty. There is no mutuality, for the
beneficiary has no duty to the fiduciary by virtue of the fiduciary relation-
ship as such.
Second, the argument is only falsely suggestive of a contractual justi-

fication for fiduciary duties. Easterbrook and Fischel do not in the end
claim that fiduciary duties are contractual terms in the ordinary sense.
They are not based on the common intent of the parties, express or im-
plied. Rather, they are purportedly imposed by courts on a hypothetical
footing, upon judicial determination of what reasonable people would do

ten friends and relatives of the settlor with no understanding of legal formalities of
trust administration, let alone professional skill in investment or maintenance of trust
property.

39 For example, a lawyer will be considered a fiduciary of her client regardless whether

the client happens to be a fellow lawyer or a judge.

al gain: Contract and Fiduciary, supra note 30 at 426.

984

in the circumstances. The normative difference between real and hypo-
thetical bargains is immense. Hypothetical contracts are counterfactual
constructions of reason; they lack the immediate and direct normative
suasion for ordering private legal relations that real bargains have. Fur-
thermore, their justificatory power turns on the real world tractability of
presuppositions that inform the hypothetical (here, that the parties are
free to behave, and would behave, as economically rational persons with-
out contingent preferences, endowments, or capacities).
Ultimately, then, Easterbrook and Fischels variant on the argument
from contract rests on contractualist rather than contractual reasoning. It
is thus not actually a reductivist argument. Hypothetical contracts do not
furnish actual contractual justification. Indeed, their appeal to philoso-
phers lies in their potential as a source of general moral and political jus-
tification.42 But Easterbrook and Fischel do not employ the hypothetical
contract device in that way.43 They feel that it proves that fiduciary duties
are the same sort of obligations, derived and enforced in the same way,
as other contractual undertakings.44 They are wrong.

Supposing fiduciary duties are not contractual, might they nonethe-
less share with contractual duties a normative foundation in consent? If
so, the above-noted insights about fiduciary liability might be accounted
for in a manner which demonstrates the affinity of fiduciary and contract
law without raising problems generated by contract-based reductivist ar-
gument.

James Edelman has recently offered an argument of this sort.45 He
claims that fiduciary duties are best understood as founded on voluntary
undertakings. More particularly, they are an express or implied term of
an engagement accepted by the fiduciary. According to Edelman:
Fiduciary duties … arise in the same manner as any other express or
implied term: by construction of the scope of voluntary undertak-
ings. They are not duties which are imposed by law nor are they

42 See generally John Rawls, A Theory of Justice (Cambridge, Mass: Harvard University
Press, 1999); David Gauthier, Morals by Agreement (Oxford: Clarendon Press, 1986);
TM Scanlon, What We Owe to Each Other (Cambridge, Mass: Belknap Press, 1998).

43 Easterbrook and Fischel write:

The rhetoric of contract is a staple of political and philosophical debate. Con-
tract is a term for voluntary and unanimous agreement among affected par-
ties. It is therefore a powerful image. It shows up in arguments about social
contracts that justify political society. … Yet arguments about social con-
tracts are problematic. They are constructs rather than real contracts (Cor-
porate Contract, supra note 30 at 1428).

45 James Edelman, When Do Fiduciary Duties Arise? (2010) 126:2 Law Q Rev 302.

JUSTIFYING FIDUCIARY DUTIES 985

necessarily referable to a relationship or status. It is time to move
from thinking of fiduciary duties as a matter of status to under-
standing them as based upon consent.46

Wishing to emphasize the continuity between contract and voluntary
undertaking, Edelman argues that in each case obligations are founded
on the consent of the obligor. Consent is a necessary condition of fiduci-
ary obligation.47 Courts are said to engage in construction of the terms of
consent in determining whether fiduciary duties were thereby expressly
or impliedly undertaken.48 Fiduciary duties are typically implied in cir-
cumstances of trust, confidence, power, vulnerability and/or discretion.49
These factors evidence an understanding or expectation in a reasonable
person that he would behave in a particular way (for example, not put
himself in a position of conflict, not make an unauthorized profit, and act
in good faith and in the best interests of the beneficiary).50
Relative to Easterbrook and Fischels account, Edelmans approach of-
fers the virtues of parsimony and enhanced explanatory power. It is a
purer and less intricate voluntarist account of the justification for fiduci-
ary duties. The argument is, in essence, that fiduciaries are rightly sub-
jected to fiduciary duties where they consent to them. However, Edel-
mans concession that consent may be implied dilutes the voluntarist ap-
peal of his argument and brings it quite close to that of Easterbrook and
Fischel. Each says that fiduciary duties may be imposed on the basis of a
judicial determination of whether this would be consistent with the expec-
tations of reasonable persons. It is just that Easterbrook and Fischel focus
on agreement (what reasonable parties to a hypothetical contract would
have agreed to), while Edelman focuses on consent (what a reasonable
person must be taken to have accepted, whether on a contractual or ex-
tracontractual basis). Each contemplates the imposition of fiduciary du-
ties on the basis of actual or constructive consent, with construction guid-
ed by legal or economic standards of reasonableness. Edelmans account
enjoys improved explanatory power simply because most fiduciary rela-
tionships are entered into voluntarily by the fiduciary, even if not through
contract.
Edelman improves on the argument from contract. However, his ac-
count is also unsound. Descriptive problems arise from the insistence that
consent, divorced from any concept of the fiduciary relationship, is suffi-

cient to ground fiduciary duties.51 To appreciate the significance of con-
sent to fiduciary liability, one must understand how it factors into the
formation and during the currency of the fiduciary relationship. It is true
enough that fiduciary liability is ordinarily premised upon voluntary un-
dertakings, as most fiduciary relationships are established consensually.
But it turns out that consent in itself offers little explanatory yield.

First, while the engagement of a fiduciary is ordinarily consensual, fi-
duciary relationships are sometimes (if rarely) established constructively,
and consent is never in itself sufficient to make a relationship fiduciary.
Parents have fiduciary duties toward their children as a matter of right,
without any requirement of consent.52 In most countries, directors and
fund managers have fiduciary duties to corporations and investors as a
matter of legislative decree. Presumably, the occupation of these offices is
consensual, but consent does not explain the imposition of fiduciary duties
on all holders of the office as a matter of law. Fiduciary duties are at-
tached to the office by the statute under which they are created or regu-
lated. The same is true of relationships deemed to have fiduciary status.

Second, the list of factors said to support the implication of fiduciary
duties raises the question of the significance of the fiduciary relationship
to fiduciary liability. Edelman says implication is warranted where a rela-

51 Edelman states, [T]he focus in fiduciary cases must shift from a debate about which re-
lationships are fiduciary … to a focus upon whether duties are expressed or implied in
relationships involving manifestations of voluntary undertakings (ibid at 325). Com-
pare Easterbrook and Fischel, who implicitly recognize the importance of conceptualiz-
ing the fiduciary relationship by elaborating on characteristics of relationships between
experts and nonexperts: Contract and Fiduciary, supra note 30; Corporate Contract,
supra note 30.

52 Michael Bryan states that

it is generally accepted that the parent-child relationship cannot be described
in private law terms. Parental responsibilities are not, for example, founded
on some implied contract to support and nurture the child. … One private law
concept, however, the fiduciary concept, has emerged from jurisprudential
obscurity to become a general explanation of parental responsibility. Parents
have been held to owe children fiduciary obligations arising from the domi-
nance and influence which they can exert over their children in their forma-
tive years (Parents as Fiduciaries: A Special Place in Equity (1995) 3:2 Intl
J Child Rts 227 at 228).

According to Scott and Scott, the relationship is fiduciary as a matter of status. The on-
ly material contract is the notional one between the state and parents, under which the
latter are accorded broad authority over their children, subject to fiduciary constraints.
They write: The contract metaphor makes explicit what is implicit in contemporary
family law: parental rights are granted as ex ante compensation for the satisfactory
performance of voluntarily assumed responsibilities to provide for the child’s interests
(Elizabeth S Scott & Robert E Scott, Parents as Fiduciaries (1995) 81:8 Va L Rev 2401
at 2404).

JUSTIFYING FIDUCIARY DUTIES 987

tionship is characterized by trust, confidence, power, vulnerability and/or
discretion.53 However, he does not explain these terms, let alone the sup-
port they provide for implying fiduciary duties. It is telling, however, that
these factors are among the most discussed indicia of fiduciary relation-
ships.54 Edelmans argument appears to be that fiduciary duties are im-
plied terms governing interactions that have the classic hallmarks of a fi-
duciary relationship. Fiduciary relationships generate fiduciary duties.
That is right of course, but we want to know why fiduciary relationships
generate fiduciary duties.
Edelmans analysis has normative failings as well. Consent is capable
of reconciling fiduciary duties with the imperative of respect for autono-
my. With rare exceptions, it would be inconsistent with that imperative
for the law to require one person to serve another as a fiduciary. That
would be to enable individuals or the state to coercively extract servility
from others. Consent is thus ordinarily a necessary condition of fiduciary
liability. However, it is not a sufficient condition, as consent alone does
not give reason for imposing the duty of loyalty. It is surely significant
that most fiduciaries undertake voluntarily to act in the beneficiarys in-
terest, but it remains unclear why the law insists upon that undertaking
as a condition of entering a fiduciary relationship.

B. The Argument from Property

Another popular reductivist argument holds that fiduciary duties are
a kind of private property right or are necessarily incidental to private
property rights. So understood, fiduciary duties enhance ownership by fa-
cilitating delegation of power over property and protect ownership inter-
ests by deterring misappropriation or misapplication of that property. The
justification for fiduciary duties derives from that for ownership and pri-
vate property rights.

The argument from property also draws attention to important as-
pects of fiduciary liability. The first is that many fiduciary relationships
involve the exercise of power by the fiduciary over property owned (in a
legal or equitable sense) by the beneficiary.55 The second is that by con-

53 Edelman, supra note 45 at 317.
54 I discuss these and other commonly cited indicia of fiduciary relationships in Paul B

Miller, A Theory of Fiduciary Liability (2011) 56:2 McGill LJ 235 at 243-47, 253-56.

55 The classic example is of course the relationship between trustee and cestui que trust
with respect to trust property. The trustee holds the legal interest in the property and
associated legal rights. The cestui holds the beneficial interest in the property and asso-
ciated equitable rights. Fiduciary regulation of the relationship between trustee and
cestui supports the functions of property law in the ways noted above. It enhances own-
ership (in particular, the effective authority of settlors) by facilitating delegation of

straining the exercise of power over property, fiduciary duties deter the
misapplication or misappropriation of property. The third is that rights
correlative to fiduciary duties have the appearance of property rights in
that they secure the exclusivity of the beneficiarys claim on the exercise
of fiduciary power. This suggests that fiduciary power over property may
itself be a form of property belonging to the bundle of rights constitutive of
ownership.
Here again there are two variants of the argument. The first, ad-
vanced by Larry Ribstein, blends arguments from contract and property.
Ribstein claims that all fiduciary relationships involve the contractual
delegation of broad power over ones property.56 Fiduciary duties are jus-
tified solely on the basis of characteristics of the fiduciary relationship, so
understood.57 Ribstein endorses Easterbrook and Fischels argument that
fiduciary duties are implied terms of contract.58 He believes, however, that
fiduciary duties respond to the exigencies of contractual delegation of
power over property rather than to the hiring of expertise. All fiduciary
relationships are said to feature separation of ownership and control of
property. Beneficiaries are entitled to residual benefit from property
subject to fiduciary administration. Fiduciaries exercise control over that
property. Fiduciary duties govern fiduciary relationships by default be-
cause the fiduciarys discretion cannot readily be constrained by devices
other than fiduciary duties without undermining the owners objectives in
delegating control.59

The elements of Ribsteins analysis adopted from Easterbrook and
Fischel are subject to the criticisms raised above. The innovative argu-
ments from property are problematic as well. Consider first the descrip-
tive issues.

power over property to a third party. It protects property rights (of the settlor and, ul-
timately, her intended beneficiaries) by deterring misapplication and misappropriation
of trust property received under delegated power.

56 Ribstein, Are Partners Fiduciaries?, supra note 1 at 212. See also Cooter & Freedman,
supra note 2 (explaining that in paradigmatic forms of the fiduciary relationship, a
beneficiary entrusts a fiduciary with control and management of an asset at 1046).

57 [T]he existence of default fiduciary duties depends solely on the structure of the par-
ties relationshipthat is, on the terms of their express or implied contractand not on
any vulnerability arising other than from this structure (Ribstein, Are Partners Fidu-
ciaries?, supra note 1 at 212).

58 Fiduciary duties are a type of contract term that applies, in the absence of a contrary
agreement, where an owner who controls and derives the residual benefit from proper-
ty delegates open-ended management power over property to a manager (ibid at 215).

59 Ibid ^×..

JUSTIFYING FIDUCIARY DUTIES 989

First, while many fiduciary relationships involve the exercise of power
over property, not all do. The paradigmatic fiduciary relationship between
trustee and beneficiary is a misleading paradigm in that respect. Many
relationships of recognized fiduciary status do not necessarily implicate
any of the beneficiarys proprietary interests. Parents enjoy fiduciary
power over the person and property of their children. Lawyers enjoy fidu-
ciary power over legal interests (rights, obligations, powers) of clients that
often have no bearing on their property. In many cases, the interests sub-
ject to the fiduciary relationship cannot reasonably be construed as pro-
prietary.

Second, it follows that fiduciary duties do not just prevent misapplica-
tion or misappropriation of property. The duty of loyalty also prohibits
conflicts that might compromise the pursuit of a beneficiarys other prac-
tical interests.

This carries a clear normative implication. If beneficiaries are often
not owners and the interests subject to fiduciary relationships are often
not proprietary, it follows that the normative foundations for property
rights and ownership cannot alone support fiduciary duties. Where fiduci-
ary law protects property rights and enhances ownership, it does so in a
manner incidental to its core purpose.
Gordon Smith has offered an interesting variant on the argument
from property.60 He is keenly aware of the limitations of an argument
from the law of property:

Lawyers have long understood that one who deals with property on
behalf of the beneficial owner of the property is subject to fiduciary
duties. The quintessential fiduciary relationshipthe trustfollows
this pattern. Despite the obvious connection between property and
fiduciary duty in the trust context, property-based theories of fiduci-
ary duty have not commanded widespread support because so many
fiduciary relationships appear to exist without the requisite proper-
ty.61

Smith gets around the problem of identifying as property interests
that are not by referring instead to resources. He defines the fiduciary
relationship as follows: fiduciary relationships form when one party (the
fiduciary) acts on behalf of another party (the beneficiary) while exercis-
ing discretion with respect to a critical resource belonging to the benefi-
ciary.62

Smith says that he substituted critical resource for property partly
in recognition of the fact that fiduciary relationships must have an ob-
ject.63 He explains the meaning of critical resource as follows:

Like property, critical resources may be tangible or intangible. The
owner of critical resources need not have legally enforceable rights
in the same way that an owner of property has such rights, but she
must have residual control rights that, at a minimum, provide prac-
tical control over the resources.64

Like Ribstein, Smith locates the justification for fiduciary duties in the
nature of the fiduciary relationship. More particularly, he says that fidu-
ciary duties are justified by the vulnerability of the beneficiary to the fi-
duciary. He explains, [T]he beneficiarys vulnerability emanates from an
inability to protect against opportunism by the fiduciary with respect to
the critical resource. … [F]iduciary law can be justified on the grounds
that it deters opportunistic behavior.65

Smith claims superior explanatory power for his theory. He argues
that other attempts to rationalize the law of fiduciary duty … share a
common failing, namely, the inability to simultaneously identify all fidu-
ciary relationships and distinguish fiduciary relationships from nonfidu-
ciary relationships.66 Unfortunately, the substitution of critical resource
for property does not appreciably increase the explanatory power of the
argument. The former concept is not well-defined. We are told nothing
about the character of a resource other than that, like property, it encom-
passes tangible and intangible things. In any event, fiduciary relation-
ships feature objects that cannot plausibly be construed as resources, in-
cluding persons.67

The critical resource theory is also normatively unconvincing. Smith
argues that fiduciary duties are justified by the beneficiarys need for pro-
tection from opportunistic appropriation of critical resources. But it is not
clear that the concept of a critical resource has any normative significance
at all. For its significance to be clear, one would need to know what makes

63 [T]he concept of property adds nothing to the analysis of fiduciary duty that a less en-
cumbered concept like critical resource cannot contribute. Whatever concept is select-
ed, it must serve one crucial function: It must convey the idea that something resides at
the core of the fiduciary relationship (ibid at 1443).

C. The Argument from Tort

The last reductivist argument for consideration is one that has sur-
prisingly found virtually no academic support. As I will explain, breach of
fiduciary duty has sometimes been called a tort. But no one has yet ar-
gued that it is properly understood as a tort.
This is surprising because, in one sense, an argument from tort is the

most logical avenue of reductive analysis. The boundaries of tort law are
notoriously ill-defined. Indeed, it has been described as the umbrella cat-
egory68 of private law and, more colourfully, as a site of indexed chaos.69
The coherence of tort law has been doubted.70 If it is an umbrella catego-
ry, why not place fiduciary duties within it? That might resolve the prob-
lem of classifying fiduciary duties, even if order is achieved at the cost of
analyticity.

The problem is that the loss of analyticity is too much to bear. Treat-
ing torts as a collection bin for the bric-a-brac of private law affords taxo-
nomical flexibility at the expense of genuine taxonomical utility. If it is
unclear what characteristics an obligation must have to count as a tort
duty, calling it a tort duty tells us nothing of its nature or relationship to
other kinds of private law obligations.
Without purporting to resolve the question of its coherence, it may be
noted that tort law may have some defining purpose. Several theorists
have attempted to articulate the core aims of tort law. These efforts may
enable us to entertain hypothetical arguments that breach of fiduciary
duty should be considered a tort.

J Postema, ed, Philosophy and the Law of Torts (Cambridge, UK: Cambridge University
Press, 2001) 1 at 1.

70 Cane explains:

[W]hile contract and trust (and here I use this term to cover both the in-
stitution of the trust and the (fiduciary) principle against self-seeking behav-
iour) are coherent expository categories … tort … [is] much less coherent. …
The lack of coherence within tort law is reflected in the fact that many of the
standard works on the law of tort begin by admitting how difficult it is to de-
fine a tort or even concisely to explain the scope and boundaries of the law
of tort (supra note 68 at 201).

(2013) 58:4 MCGILL LAW JOURNAL ~ REVUE DE DROIT DE MCGILL

992

One theory is that torts are civil wrongs.71 On this view, tort law is of
uniquely broad scope when compared with the other bases of private lia-
bility in that it encompasses not merely wrongs against persons but also
interference with property and contractual rights. The civil wrongs theory
builds on the recognition that tort liability is premised on wrongdoing but
not necessarily risk, harm, or fault.

The civil wrongs theory of tort law may well have more explanatory
power than its competitors. But the concept of a civil wrong is so broad
that the theory is of little use in dealing with core problems of classifica-
tion and justification of private law obligations.72 The concept is insensi-
tive to differences in the character of discrete wrongs that are relevant to
these problems.73 It may be, for instance, that trespass to land and know-
ing interference with contractual relations are civil wrongs that have been
classified as torts. But one must appreciate the nature of the right to ex-
clusive possession of property or to performance of contractual undertak-
ings to understand the character of the wrongs. Understanding the nature
of rights, duties, wrongs, and remedies is essential to articulating their
justification. It is also relevant to reasoned classification. Breach of fiduci-
ary duty is a civil wrong. But that tells us nothing of its distinctive wrong-
ful character and gives little reason for classifying it a tort.
Another view is that torts are civil wrongs of harmful interference.
Tort law is focused primarily on compensation for harm to protected in-

71 The most highly developed account is that of John Goldberg and Benjamin Zipursky.

They state:

Tort is indeed a basic category of law. To see this, however, one must aban-
don the notion, now deeply entrenched, that tort law is law for allocating the
costs of accidents. As its name indicates, tort law is about wrongs. The law of
torts is a law of wrongs and recoursewhat Blackstone called private
wrongs (Torts as Wrongs (2010) 88:5 Tex L Rev 917 at 918).

See also Peter Birks, The Concept of a Civil Wrong in David G Owen, ed, Philosophi-
cal Foundations of Tort Law (Oxford: Clarendon Press, 1995) 31.

72 Goldberg and Zipursky claim conceptual unity for the idea of a civil wrong:

[T]he wrongs recognized by tort law hardly make for an eccentric or random
collection. Tortious wrongdoing always involves an interference with one of a
set of individual interests that are significant enough aspects of a persons
well-being to warrant the imposition of a duty on others not to interfere with
the interest in certain ways, notwithstanding the liberty restriction inherent
in such a duty imposition (supra note 71 at 937 [footnotes omitted]).

This may be a reasonable definition of a civil wrong, but it does not furnish a basis upon
which to distinguish tortious wrongs from other kinds of wrongs. Breach of contract and
breach of fiduciary duty can be construed as involving interference with interests signif-
icant to individual welfare. To consider them torts for that reason alone ignores the
question how torts are differentiated from other kinds of civil wrongs.

terests.74 Protected interests range from the personal (e.g., interests in
privacy and physical integrity) to the proprietary (e.g., interests in exclu-
sive possession of property or performance of contractual obligations).
Breach of fiduciary duty sometimes involves harmful interference by
the fiduciary with the beneficiarys personal or proprietary interests.75 It
might thus be thought that breach of fiduciary duty is just another tort of
harmful interference. This view seems to be reflected in the second Re-
statement of Torts, which provides that an individual standing in a fidu-
ciary relation with another is subject to liability to the other for harm re-
sulting from a breach of duty imposed by the relation.76

The difficulty with this view is that fiduciary liability is not contingent
on interference, let alone harmful interference. Disloyalty sometimes in-
volves assault, theft, or misappropriation, but harmful interference with
the person or property of the beneficiary is not essential.77 Fiduciaries are
liable where they personally take property or profits obtained through the
exercise of fiduciary power, regardless of whether the beneficiary had a
pre-existing entitlement to, or even a reasonable expectation of procuring,
the property or profits. The duty of loyalty prohibits conflicts regardless of
whether their realization entails a risk of harm to the beneficiary. Equal-
ly, fiduciary remedies are not merely compensatory. Gain-based remedies
require the fiduciary to pay over profits and property to the beneficiary
whether or not the underlying disloyalty involved conduct that could be

74 Jules Coleman and Gabriel Mendlow explain:

[T]orts require … wrong and, in most cases, harm. A notable exception to the harm
requirement is the case in which injunctive relief is awarded in order to prevent
harm that is virtually certain but yet to occur. As a general rule though torts re-
quire both wrongs and harms (Theories of Tort Law in Edward N Zalta, ed,
The Stanford Encyclopedia of Philosophy, Summer 2010 ed, online: ).

sponsibility in David G Owen, ed, Philosophical Foundations of Tort Law (Oxford:

beneficiaries for any losses associated with breach of fiduciary duty).

77 As Peter Cane recognized, Fiduciary obligations are different from any obligation im-
posed by tort law. As a general rule, tort law does not require people to act for the bene-
fit of others and to ignore their own interests, but only to avoid causing disbenefit to
others (supra note 68 at 189-90).

construed as conversion.78 Whether considered from the perspective of
wrongs or of remedies, it is clear that breach of fiduciary duty is not mere-
ly a tort.

IV. Instrumentalist Justifications
Our discussion has thus far shown the failure of the reductivist strat-
egy in justifying fiduciary duties. This alone gives us a reason to think
that fiduciary duties are distinctive and to predict that a successful justi-
ficatory strategy will treat them as such. The other dominant analytical
strategythe instrumentalist strategyaccepts that fiduciary duties are
distinctive but typically ignores, denies, or diminishes the possibility that
a justification might be rooted in the juridical character of liability.

There are several varieties of instrumentalist argument.79 The varia-
tion reflects differences in the character of stipulated ends for law as well
as differences in the structure of justificatory analysis. Some instrumen-
talists state as normatively desirable ends the satisfaction of moral norms
or the achievement of public policy goals.80 Others understand the end to
be a legal principle or a consideration peculiar to legal institutions or the
integrity of law. Furthermore, instrumentalist justificatory analysis may
be direct or indirect in structure. Direct analyses seek to justify the con-
tent of an obligation directly on the basis of the stipulated independent
end. Indirect analyses accept that obligations are supported by juridical
reasons but claim that the latter are best explained in light of a stipulated
independent end. As we shall see, instrumentalist arguments about the
justification for fiduciary duties tend to be direct.81

78 Deborah A DeMott explains, [T]he basic rationale of tort law is to compensate people
for injuries inflicted upon them and for losses they have suffered. In contrast, a fiduci-
arys liability is often to account for profit realized by the fiduciary when the fiduciarys
conduct has not inflicted injury on anyone (Fiduciary Obligation Under Intellectual
Siege: Contemporary Challenges to the Duty to Be Loyal (1992) 30:2 Osgoode Hall LJ
471 at 488).

79 See Robert Samuel Summers, Instrumentalism and American Legal Theory (Ithaca:
Cornell University Press, 1982); David Lyons, Legal Formalism and Instrumentalism:
A Pathological Study (1981) 66:5 Cornell L Rev 949.

80 William W Bratton, for example, states that

[t]he traditional commentary justifies the imposition of the fiduciarys

legal duty on two grounds. One is ethicalfiduciary exercise of power for
self-interested reasons is wrong. … The other justification is practicalthe
imposition of the duty facilitates productive relationships, whether of trust or
of agency (Self-Regulation, Normative Choice, and the Structure of Corpo-
rate Fiduciary Law (1993) 61:4 Geo Wash L Rev 1084 at 1101).

81 It may be that indirect instrumentalism is the more attractive of the two forms of in-
strumentalist argument. An indirect instrumentalist may accept that fiduciary duties

JUSTIFYING FIDUCIARY DUTIES 995

A. The Argument from Morality
It is sometimes said, without much elaboration or specificity, that fi-

duciary law is concerned with ensuring that fiduciaries behave morally82
and that the duty of loyalty requires fiduciaries to act altruistically.83 But,
more commonly, one sees a narrower argument from morality. Specifical-
ly, it is said that fiduciary duties have moral justification because they
provide a secure basis for interpersonal trust. Fiduciary relationships are
said to be relationships of trust.84 Fiduciary duties are thought justified on
the basis that they promote trust either directly or by securing conditions

are justified juridically on the basis of properties of fiduciary relationships but never-
theless maintain that the ultimate (i.e., philosophical rather than juridical) justification
for fiduciary duties is instrumental. For instance, it might be said that fiduciary rela-
tionships are justifiably recognized as a form of legal relationship because they facili-
tate an economically efficient allocation of productive capacities (i.e., personal legal
powers). Fiduciary duties are, by implication, justified on the basis that they preserve
the efficient allocation of productive capacities accomplished by fiduciary relationships.
An argument such as this might indeed be compelling. But for present purposes I am
not interested in considering all possible justificatory arguments for fiduciary duties or
even the relationship between juridical and philosophical justifications. My aim is in-
stead to consider the strengths and weaknesses of leading arguments in the literature.
It just happens that these arguments take a direct instrumentalist form. I am grateful
to Henry Smith and Stephen Smith for pressing this point.

82 The classic articulation is found in the judgment of Justice Cardozo in Meinhard: A
trustee is held to something stricter than the morals of the marketplace. Not honesty
alone, but the punctilio of an honor the most sensitive, is then the standard of behavior
(supra note 24 at 546). Austin Scott relied on the philosopher Josiah Royce for the prop-
osition that, [i]n loyalty, when loyalty is properly defined, is the fulfilment of the whole
moral law (Josiah Royce, The Philosophy of Loyalty (New York: Macmillan Company,
1908) at 15, cited in Austin Scott, The Fiduciary Principle (1949) 37:4 Cal L Rev 539
at 540). See also Frankel, Fiduciary Law, supra note 1 ([c]ourts regulate fiduciaries
by imposing a high standard of morality upon them. This moral theme is an important
part of fiduciary law. Loyalty, fidelity, faith, and honor form its basic vocabulary at
829-30 ^×.).

the role of morality in contract law at 830); Arthur B Laby, The Fiduciary Obligation
as the Adoption of Ends (2008) 56:1 Buff L Rev 99 (arguing that fiduciary duties are
Kantian imperfect duties of virtue); Birks, Content of Obligation, supra note 15 (argu-
ing that fiduciary duties compel altruistic behavior); Smith, Heart of Corrective Judg-
ment, supra note 6 (arguing that the duty of loyalty requires fiduciaries to have other-
regarding motives and thus to act altruistically).

84 See Dolton v Capitol Federal Savings and Loan Association, 642 P (2d) 21 (available on

Ltd v Boughton & Co, [1991] 3 SCR 534, 85 DLR (4th) 129 [cited to SCR] (the fiduciary
relationship has trust, not self-interest, at its core. … [E]quity is concerned, not only to

of trustworthiness that make it rational to place trust in fiduciaries.85 The
moral value of interpersonal trust may be understood as intrinsic (e.g.,
trust is critical to human flourishing given our interdependence) or in in-
strumental terms (e.g., trust enables individuals to co-operate effectively
toward achievement of socially desirable ends). In either event, the justifi-
cation for fiduciary duties is attributed to the moral value of trust.

Lawrence Mitchell, for instance, has argued that fiduciary duties
make trust rational in relationships for which trust has functional signifi-
cance.86 The functional significance of trust lies in its facilitation of coor-
dinated productive activity.87 Speaking of relationships between business
partners, Mitchell explains:

No law or contract is likely to substitute for the trust and mutual
regard of the parties. But law can be used in a way that will help to
foster the development of trust and make it more rational. …
Fiduciary duty … [makes] trust rational. … [A] fiduciary duty
gives each party a reason to trust the other in a long-term relation-
ship of unforeseeable consequences because, backed by legal sanc-
tions, it requires each party to act as if it were trustworthy.88

On Mitchells view, fiduciary relationships are not founded on trust
but are instead relationships in which liability rules render placement of
trust secure.89 Rational actors will be willing to trust one another knowing
that betrayal will be deterred by the threat of liability.
Robert Flannigan, by contrast, argues that fiduciary duties are found-
ed on trust understood as a good (i.e., a form of social capital) with inher-
ent moral value. According to Flannigan, [t]here is … no doubt as to the
source of the fiduciary obligation. It is the trust which one person places

85 See Frankel, Fiduciary Analysis, supra note 27 (an important underlying objective of
fiduciary law is to maintain trusting relationships at 317). Frankel has since explained
that placement of trust in the fiduciary is not essential, but she maintains that fiduci-
ary duties secure the trustworthiness of fiduciaries. Arguing that fiduciary duties enti-
tle entrustors to trust and rely on fiduciaries honesty, she states:

Although courts sometimes describe entrustors as persons who actually trust
their fiduciaries, courts have not required such actual trust as a basis for
finding fiduciary relationships and attendant duties. Fiduciaries should be
trustworthy, not necessarily trusted (Default Rules, supra note 36 at 1227-
28).

86 Lawrence E Mitchell, The Naked Emperor: A Corporate Lawyer Looks at RUPAs Fi-

duciary Provisions (1997) 54:2 Wash & Lee L Rev 465 at 480.

87 Presumably, the instrumental value of trust is to be derived from the social or economic

value of productivity itself or the economic value of goods produced.

in another.90 Fiduciary duties are, he says, imposed for the singular
purpose of maintaining the integrity of trusting relationships.91 Else-
where, he elaborates:

JUSTIFYING FIDUCIARY DUTIES 997

The traditional rationale for fiduciary responsibility is straight-
forward. People trust others to act on their behalf or to perform
tasks for them. … The mischief that can occur in such circumstances
is that the trusted party will divert value away from the trusting
party. The trust placed in the trusted party, in other words, will be
abused. Public morality is offended by this kind of conduct. The
courts, openly asserting this public morality or policy, formulated a
liability rule to deter the abuse.92

Flannigan is right that fiduciary relationships place fiduciaries in a
position of power and as such generate a risk of abuse. But it does not fol-
low that fiduciary relationships are defined by trust or that fiduciary du-
ties promote trust. Fiduciary relationships may implicate trust. But there
are several problems with the notion that fiduciary duties are founded on
the moral value of trust.93
First, the meaning of trust is contested.94 Trust may be defined as any

of a number of states of mind,95 forms of conduct,96 or both (e.g., a demon-
strated attitude or emotion).97 In any event, there is no agreement about

94 See Carolyn McLeod, Trust in Edward N Zalta, ed, The Stanford Encyclopedia of Phi-
losophy, Spring 2011 ed, online: .

95 For example, Lawrence C Becker distinguishes between trust as a cognitive and a non-
cognitive state of mind: [L]et us call our trust cognitive if it is fundamentally a matter
of our beliefs or expectations about others trustworthiness; it is noncognitive if it is
fundamentally a matter of our having trustful attitudes, affects, emotions, or motiva-
tional structures that are not focused on specific people, institutions, or groups (Trust
as Noncognitive Security about Motives (1996) 107:1 Ethics 43 at 44). See also Karen
Jones, Trust as an Affective Attitude (1996) 107:1 Ethics 4.

96 See Annette Baier, Trust and Antitrust (1986) 96:2 Ethics 231 ([t]rust … is letting
other persons (natural or artificial, such as firms, nations, etc.) take care of something
the truster cares about, where caring for involves some exercise of discretionary pow-
ers at 240); Philip Pettit, The Cunning of Trust (1995) 24:3 Philosophy & Public Af-
fairs 202 ([t]he word trust is used in relation to a great number of things. The word
may be used in connection with relying on natural phenomena as well as in connection
with relying on people at 203-204).

97 For example, Matthew Harding argues that trust is an attitude of optimism … about
the choices that people will make (Manifesting Trust (2009) 29:2 Oxford J Legal Stud

(2013) 58:4 MCGILL LAW JOURNAL ~ REVUE DE DROIT DE MCGILL

998

what trust comprises. There are other complexities. Trust may be unilat-
eral or reciprocal.98 It applies to different levels and kinds of social inter-
action (interpersonal, organizational, public, and political). It also has dif-
ferent objects (e.g., one can trust in the testimony of another, their prom-
ises, their competence, and so on). The correlative concept, trustworthi-
ness, is equally unclear.99 It is uncertain whether trustworthiness is a
function of the character, competencies, or motivations of a person in
whom trust is to be placed; the nature of the relationship between those
who give and receive trust; or the social, political, organizational, and le-
gal contexts which might influence their motivation or behavior. So long
as it lacks clear meaning, trust cannot justify fiduciary duties.

Second, claims that the functional value of trust justifies fiduciary du-
ties rest on the questionable premise that these functions have stable
moral value. There is reason to doubt this. Most consider that, whatever it
is, trust is purposivethat is, one person trusts another to do something
(e.g., to tell the truth, to keep promises).100 If that is true, the moral value
of trust turns at least in part on that of its purpose. As Annette Baier
notes, there are immoral as well as moral trust relationships, and trust-
busting can be a morally proper goal.101

Third, the case that the duty of loyalty is trust reinforcing has not
been made out. Some have argued that threats of legal sanction, or the
security the threat of sanctions provides, are inimical to trust.102 Whether
this is true or not, a positive argument must be made for the trust-
reinforcing function of fiduciary liability. Without one, we have no reason
to believe that there is any causal relationship between levels of trust and
fiduciary liability.

fested in action (ibid at 247).

99 See Russell Hardin, Trust and Trustworthiness (New York: Russell Sage Foundation,
2002) (arguing that insufficient attention has been paid to trustworthiness and claim-
ing that the complexity of the problem of trust derives primarily from the complexity of
the problem of trustworthiness. … [T]he motivations for being trustworthy are mani-
fold at 31).

100 See McLeod, supra note 94.
101 Baier, supra note 96 at 232.
102 For example, Larry Ribstein argues that law has nothing to do with trust. … [L]aw ac-
tually may undermine trust, and therefore serve as a substitute rather than a comple-
ment (Law v. Trust (2001) 81:3 BUL Rev 553 at 576). For criticism, see Frank B
Cross, Law and Trust (2005) 93:5 Geo LJ 1457.

JUSTIFYING FIDUCIARY DUTIES 999

Finally, trust is not an essential quality of fiduciary relationships.103

Reposal of trust by a beneficiary, whatever that might mean, does not
necessarily factor in the formation of relationships established by decree
or undertaking. Further, depending how it is defined, trust may or may
not arise subsequently. Even where present, trust is not a unique quality
of fiduciary relationships. As DeMott observes, the trusting behaviour
that a fiduciary relationship may engender does not adequately furnish a
basis on which to differentiate among relationships or actors.104 Trust
may or may not be present in fiduciary relationships; likewise, it may or
may not be present in nonfiduciary relationships (e.g., contractual rela-
tionships). The moral value of trust is therefore not alone sufficient to ex-
plain or justify fiduciary duties.

B. The Argument from Policy

It is also sometimes said that fiduciary liability is founded on consid-
erations of public policy.105 Paul Finn has advanced the most influential
argument from public policy.106 Finn, author of the groundbreaking trea-

103 Unless one defines trust circularly as denoting properties of fiduciary relationships (see
Baier, supra note 96), in which case, reference to trust simply begs the question con-
cerning the meaning and normative salience of the properties.

105 As stated in Guth v Loft, Inc, 5 A (2d) 503 at 510 (available on WL Can) (Del Sup Ct

1939):

A public policy, existing through the years, and derived from a profound
knowledge of human characteristics and motives, has established a rule that
demands of a corporate officer or director, peremptorily and inexorably, the
most scrupulous observance of his duty, not only affirmatively to protect the
interests of the corporation committed to his charge, but also to refrain from
doing anything that would work to the injury of the corporation, or to deprive
it of profit or advantage which his skill and ability might properly bring to it.
… The rule that requires an undivided and unselfish loyalty to the corpora-
tion demands that there shall be no conflict between duty and self-interest.

tise Fiduciary Obligations, was originally dismissive of the significance of
the fiduciary relationship to fiduciary liability.107 He ultimately reversed
course108 but claimed that public policy concerns account for its signifi-
cance to fiduciary liability:

[T]hough the courts often enough emphasize the rigorous standards
exacted by the fiduciary principle … they less often acknowledge ex-
plicitly that it is, itself, an instrument of public policy. It has been
used, and is demonstrably used, to maintain the integrity, credibility
and utility of relationships perceived to be of importance in a society.
And it is used to protect interests, both personal and economic,
which a society is perceived to deem valuable.109

Concerning the duty of loyalty, Finn argues that [i]ts function … is to
secure the paramountcy of one sides interests or in some instances, as
with partnerships, of a joint interest.110 This is said to be a matter of pub-

cation for fiduciary duties. However, no one has developed a comprehensive argument
that fiduciary duties are justified solely on the basis of efficiency. Instead, arguments
from efficiency emanate from claims that fiduciary duties are contractual duties. For
example, Cooter and Freedman have argued that fiduciary duties are implied default
rules that resolve transactional inefficiencies in relational contracts: supra note 2 at
1064-65. Ribstein and other adherents of law and economics have made similar claims:
[C]orporate rules ultimately are and, from an efficiency perspective, should be the
product of private ordering, not government regulation. Even where liability rules are
appropriate, they should be regarded as standard form contractual provisions that can
be drafted around (Henry N Butler & Larry E Ribstein, Opting Out of Fiduciary Du-
ties: A Response to the Anti-contractarians (1990) 65:1 Wash L Rev 1 at 71). It may be
that a comprehensive argument from economic efficiency could be disentangled from
contractarian analyses of commercial fiduciary relationships. The suggestion is, howev-
er, purely speculative.

107 Finn writes:

[F]iduciary … is not definitive of a single class of relationships to which fixed
rules and principles apply. Rather its use has generally been descriptive,
providing a veil behind which individual rules and principles have been de-
veloped. This conclusionan incontestable oneis the starting point of this
work. In the following pages it will be suggested that it is meaningless to talk
of fiduciary relationships as such (PD Finn, Fiduciary Obligations (Sydney:
Law Book Company Limited, 1977) at 1 [footnotes omitted]).

108 Finn wrote:

[O]ur present uncertainty is thought to be exacerbated by the lack of a work-
able and unexceptionable definition of a fiduciary. We have no shortage of ri-
val approaches, but none has carried the day. … [T]here is the obvious hazard
of fiduciary becoming either a chameleon or an accordion term. Definition,
howsoever imperfect, has its place (Fiduciary Principle, supra note 106 at
26 [footnotes omitted]).

JUSTIFYING FIDUCIARY DUTIES 1001

lic interest and, as such, a proper concern for public policy. Finn con-
cludes:

In this the true nature of the fiduciary principle is revealed. It
originates, self-evidently, in public policy: in a view of desired social
behaviour for the end this achieves. To maintain the integrity and
the utility of those relationships in which the (or a) role of one party
is perceived to be the service of the interests of the other, it insists
upon a fine loyalty in that service.111

Finn rightly emphasizes the public importance of certain fiduciary re-
lationships. Who could deny the personal and social significance of rela-
tionships between directors and corporations, doctors and patients, and
parents and children? That being said, Finn leaves unarticulated the con-
nection between the public importance of some fiduciary relationships and
the policy justification for fiduciary duties in general. A policy justification
is simply asserted. The assertion is hard to accept without analysis partly
because of Finns failure to explain the nature of the fiduciary relation-
ship. If it is unclear what makes a relationship fiduciary, it is impossible
to determine whether its characteristics engage matters of public interest,
and if so, how.

Supposing that the nature of the fiduciary relationship is such that it
does somehow engage the public interest, it remains unclear how fiduci-
ary duties advance the public interest. It is not obvious that a duty that
requires one person to focus exclusively on the interests of another will
tend to advance social welfare or some other measure of the public good.
The duty of loyalty asserts the exclusivity of interest of an individual or
discrete class of individuals and demands blinkered devotion to a man-
date defined in terms of the interests of that individual or class. It is not
impossible that the duty of loyalty might thereby advance public policy.
But the claim that it does is counterintuitive and, in any event, requires
argument.

C. The Argument from (Nonfiduciary) Law

The final form of instrumentalist argument holds that fiduciary duties
are of consequential importance to the realization of values implicit in the
law, to the promotion of lawful conduct, or to legality itself. The justifica-
tion for fiduciary duties is thus found within law but beyond fiduciary law
proper.

1002

Matthew Conaglen has articulated an argument of this sort.112
Conaglen offers a unique account of the function of the duty of loyalty. He
claims that [t]he concept of fiduciary loyalty is an encapsulation of a
subsidiary and prophylactic form of protection for non-fiduciary duties
which enhances the chance that those non-fiduciary duties will be proper-
ly performed.113 On Conaglens view, the duty of loyalty always arises
concurrently with nonfiduciary legal duties.114 It is subsidiary in that its
function is purely instrumental in relation to these duties. It is prophylac-
tic in that conflict rules deter the nonperformance of these duties.115
Conaglen argues that the justification for fiduciary duties is as follows:
it is clear that the normative justification for [the] existence [of the duty
of loyalty] is to avoid situations which involve a risk of breach of non-
fiduciary duties.116 In other words, fiduciary duties are justified instru-
mentally on the basis that they provide needed security for the perfor-
mance of nonfiduciary legal duties.
Conaglens account offers insights into fiduciary liability not men-
tioned thus far. First, fiduciary duties typically arise concurrently with
nonfiduciary (often contractual) duties. Second, fiduciary duties always
grant the beneficiary an expectation of performance. The fiduciary is ex-
pected to act in the interests of the beneficiary even if that expectation is
not itself the object of prescriptive obligation.117 Third, fiduciary duties are
functionally prophylactic in that they insulate the beneficiary from the
risk of compromised judgment by the fiduciary. The conflict rules require

Function of Fiduciary Loyalty (2005) 121 LQR 452 [Conaglen, Nature and Function].

114 Conaglen, Fiduciary Loyalty, supra note 14 (fiduciary duties subsist concurrently
alongside non-fiduciary duties with a view to making proper performance of those non-
fiduciary duties more likely at 75).

115 As Conaglen would have it, under the conflict of interest rule, a fiduciary is prohibited
from acting in a situation where there is a conflict between the basic duty which he
owes to his principal and his own personal interest because that personal interest is
likely to lead the fiduciary away from the proper performance of his duty (Nature and
Function, supra note 112 at 461). Speaking of fiduciary law more generally, he ex-
plains that the very nature of fiduciary doctrine … is itself prophylactic in the sense
that the very object of its rules and principles is to try to remove or neutralise incentives
that might tempt or otherwise motivate a fiduciary not to perform properly his non-
fiduciary duties (ibid at 469).

116 Ibid at 470.
117 Contra Birks, Content of Obligation supra note 15. The difficulty, of course, lies in
specifying precisely what the fiduciary is to do in acting in the interests of the benefi-
ciary. Conaglen thinks the fiduciary is to perform nonfiduciary duties. I present a dif-
ferent view in Part V, below.

JUSTIFYING FIDUCIARY DUTIES 1003

the fiduciary to avoid situations that would incentivize him to act contrary
to the interests of the beneficiary.
Conaglens rendering of fiduciary duties is highly sophisticated but
still problematic. The most important descriptive problem is the now-
familiar difficulty of accounting for the significance of the fiduciary rela-
tionship to fiduciary liability. Conaglen has recently confronted this prob-
lem, saying:

Legal obligations are frequently analyzed on the basis of a syllo-
gism: where the circumstances are X, there is a duty of kind Y. … It
is commonplace, therefore, when seeking to identify the function
that legal obligations serve, to focus attention on the question of
when duties of that kind arise.118

Conaglen explains that this has resulted in considerable attention
[being] focused on the concept of a fiduciary relationship as the key to un-
locking the function served by fiduciary duties.119 He declines to take this
route, however, claiming that the circumstances in which a fiduciary re-
lationship arises … are far from clear and that it is debatable whether
the syllogistic mode of analysis … accurately represents the manner in
which fiduciary doctrine operates.120
Elaborating on the first point, Conaglen points out that established
methods of identifying fiduciary relationships do not make clear why the
relationships are recognized as fiduciary in nature.121 He claims that ef-
forts to define the fiduciary relationship rest on vain hope, with chances
of success approximating those of the search for the Holy Grail.122
Conaglen supports his second point by citing a few cases in which judges,
influenced by Finn, have suggested that the syllogism operates in reverse
(i.e., that identification of a relationship as fiduciary follows from the im-
position of fiduciary duties).123
Neither of these arguments is convincing. The claim that fiduciary law
is an outlier rests on thin authority and is not based on any analysis.
Conaglen says that fiduciary relationships are identified by first deter-
mining whether fiduciary duties exist. But he does not convincingly ex-
plain the incidence of fiduciary duties. Fiduciary duties must either be
imposed as a general rule of conduct or arise by virtue of an interaction

between individuals. They do not subsist in the air, as it were. A prepon-
derance of authority treats the formation of a fiduciary relationship as a
condition precedent to liability.124

The claim that it is impossible to define the fiduciary relationship is
likewise unconvincing. A convincing definition has proven elusive. But as
I will explain in Part V.B, existing approaches to the identification of fidu-
ciary relationships provide a stable referent for definitional reasoning.

There are other problems. For instance, Conaglens argument cannot
explain the distinctively wrongful character of disloyalty and its remedial
implications. Something in the character of disloyalty justifies remedies
so robust that they would seem punitive in other contexts.125 Yet Conaglen
cannot account for the connection between disloyalty and the remedies
that correct for it. On his view, disloyalty generates liability not because it
is inherently wrongful but rather because it involves a risk of the realiza-
tion of a nonfiduciary wrong (i.e., breach of a nonfiduciary duty). But if
that is true, it is unclear why disloyalty attracts remedies more potent
than those available to correct the nonfiduciary wrongs. If the duty of loy-
alty is subsidiary and disloyalty is thus not inherently wrongful, remedies
should track those available upon breach of the underlying duty.

This problem has a normative corollary. Conaglen says that the nor-
mative justification for [the duty of loyalty] is to avoid situations which
involve a risk of breach of non-fiduciary duties.126 But it is unclear why
the risk of breach of nonfiduciary duties should justify a standard of con-
duct with the distinctive content and high burden of compliance of the du-
ty of loyalty. Nonfiduciary duties are enforceable under independent lia-
bility rules,“ and the risk of breach is deterred by the prospect of reme-
dies ordinarily available upon breach. There is nothing about risk of
breach of a nonfiduciary duty in itself that would justify the exacting de-
mand for faithfulness made of fiduciaries.

V. The Juridical Justification

So far, I have briefly described the juridical character of fiduciary lia-
bility, introduced the problem of justifying fiduciary duties, and reviewed
prominent claims about the justification for fiduciary duties. The domi-
nant justificatory strategiesreductivist and instrumentalisthave not
proven successful.

126 Nature and Function, supra note 112 at 470.

JUSTIFYING FIDUCIARY DUTIES 1005

The failures are instructive. The failure of reductivism suggests that
justificatory analysis should proceed on the basis that fiduciary liability is
distinctive. The failure of instrumentalism suggests that justificatory
analysis should properly confront the juridical character of fiduciary lia-
bility by examining justificatory reasons that may be derived from it. In
what follows, I endeavour to act on these lessons in developing a juridical
justification for fiduciary duties.

A. Recapitulation

Leading claims about the justification for fiduciary duties may have
proved unconvincing, but most illuminated important, sometimes un-
derappreciated, aspects of fiduciary liability. It may be useful to begin by
taking stock of what has been discussed thus far.

In Part II, I established the basic parameters of fiduciary liability. I
noted that there is at least one distinctively fiduciary duty, the duty of
loyalty,127 and that this duty includes conflict rules. Specifically, the fidu-
ciary must avoid conflicts between his mandate to serve the interests of
the beneficiary and his self-interest or duty to others. It was also observed
that the duty of loyalty is based on the existence of a fiduciary relation-
ship.

The arguments canvassed in Parts III and IV emphasized other im-
portant aspects of fiduciary liability. The argument from contract high-
lights several important points. It is founded on the recognition that fidu-
ciary duties are typically occasioned by fiduciary relationships established
consensually. Pertinent modes of consent differ; they include contract, in-
formed consent, informal agreements, and unilateral undertakings. The
necessity of obtaining consent likewise varies. The consent or undertaking
of the fiduciary is almost always required. The consent of the beneficiary
or a third party (e.g., benefactor or guardian) will also be required in
many cases.

The argument from contract also emphasizes the fact that fiduciary
duties frequently constrain the performance of contractual undertakings.
For instance, a lawyer who undertakes to represent a client on retainer is
constrained by the duty of loyalty in the performance of that contractual
undertaking.128 The conflict of duty rule prevents her from representing
another client in the same or conflicting matters.

127 The claim of distinctiveness in this part went to the content of the duty, not its founda-

tion, and thus did not presuppose the failure of reductivist justification.

128 See Lynn A Baker & Charles Silver, Fiduciaries and Fees: Preliminary Thoughts

(2011) 79:5 Fordham L Rev 1833.

(2013) 58:4 MCGILL LAW JOURNAL ~ REVUE DE DROIT DE MCGILL

1006

Finally, the argument from contract underscores the fact that en-
forcement of fiduciary duties may be partially determined by consent.129
While broad waivers or contractual clauses purporting to completely ex-
clude fiduciary liability are usually read down or held void, consent to
partial exclusion of fiduciary duties or ratification of breach does limit en-
forcement.130

The argument from property draws attention to other aspects of fidu-
ciary liability. It underscores the fact that fiduciaries are often vested
with power over property owned by the beneficiary. Trustees, for instance,
have power over trust property of which beneficiaries are equitable own-
ers. Directors and officers have power over assets and income of which
corporations are legal owners.

In fiduciary relationships of this sort, fiduciary duties constrain the
exercise of power over property, prohibiting its misapplication or misap-
propriation. Thus the duty of loyalty bars the trustee from taking a per-
sonal interest in trust property.131 Similarly, it forbids partners from mak-
ing personal use of partnership property or diverting profits realized
through its productive application.132 When fiduciary duties operate this
way, the correlative rights resemble property rights; they secure the ex-
clusivity of the beneficiarys claim on the resource.

129 See Easterbrook & Fischel, Contract and Fiduciary, supra note 30; Butler & Ribstein,

supra note 106.

130 Victor Brudney states:

The classic fiduciary loyalty restriction starts with a substantive back-

ground stricture that prohibits any gain for the fiduciary from any [self-
dealing] transaction. … Those prohibitions are relaxed if informed consent to
the transaction is given by the beneficiary or principal, but even then, the fi-
duciary must demonstrate both the volitional and informed character of the
consent, and that the transaction is fair (Revisiting the Import of Share-
holder Consent for Corporate Fiduciary Loyalty Obligations (2000) 25:1 J
Corp L 209 at 213 ^×.).

DeMott notes that [a] provision in a trust instrument cannot relieve a trustee of liabil-
ity for any profit derived from a breach of trust, and cannot relieve the trustee of liabil-
ity for breaches of trust committed intentionally, in bad faith, or with reckless indiffer-
ence to the interests of the beneficiary (Beyond Metaphor, supra note 16 at 923). See
also Brudney, Contract and Fiduciary Duty, supra note 29; Paul Finn, Contract and
the Fiduciary Principle (1989) 12:1 UNSWLJ 76.

131 See Restatement (Second) of Trusts 170(1) (1959) ([t]he trustee is under a duty to ad-
minister the trust solely in the interest of the beneficiaries). See also Lawrence E
Mitchell, The Death of Fiduciary Duty in Close Corporations (1990) 138:6 U Pa L Rev
1675 ([i]t is clear that trustees are prohibited from self-dealing in trust property, and
that non-trustee fiduciaries have been subjected to the same general principle at 1697).
132 See Ribstein, Are Partners Fiduciaries?, supra note 1 ([o]wners have joint rights in
firm property and, therefore, may not appropriate the property to personal use without
co-owner consent at 221).

JUSTIFYING FIDUCIARY DUTIES 1007

The argument from nonfiduciary law draws attention to yet other fea-
tures of fiduciary liability. The first is that fiduciary duties typically arise
concurrently with nonfiduciary duties. Fiduciary relationships established
by contract invariably give rise to fiduciary and contractual duties. Where
confidential information is disclosed in the execution of a fiduciary man-
date, fiduciary duties will co-exist with duties of confidence.
Another important point is that fiduciary duties support an expecta-
tion of performance. Conaglen mistakenly claims that the expectation
goes to the performance of nonfiduciary duties. The germane expectation
is that of performance of the mandate underlying a fiduciary relationship.
I will develop this point shortly. For now, it suffices to say that fiduciaries
are expected to act in the interests of the beneficiary. The duty of loyalty
supports that expectation notwithstanding the fact that there is no pre-
scriptive fiduciary obligation of performance of a fiduciary mandate.133

B. The Nature of Juridical Justification
The justificatory analysis offered here articulates reasons for the im-

position of fiduciary duties derived exclusively from the juridical character
of fiduciary liability. Juridical justification differs from reductivist justifi-
cation insofar as the reasons are taken to be distinctive of fiduciary liabil-
ity. It differs from direct instrumentalist justification insofar as private
law is taken to call for a distinctive kind of practical reasoning.134

Juridical justification treats the juridical character of private liability
as a source rather than an object of justification.135 It shares with
Zipurskys pragmatic conceptualism the premise that the focal point for
interpretive legal theory should be the concepts and principles embedded
in the law.136 Unlike pragmatic conceptualism, however, juridical justifi-
cation does not suppose that the normativity of private law is to be under-
stood in terms of extrinsic values (e.g., those derived from social practices
or conventions). Instead, it seeks to reveal the inherent justificatory struc-

133 In other words, fiduciary duties constrain the execution of a fiduciary mandate, but they

do not secure its execution.

134 Private law involves a distinctive form of practical reasoning in that judges, in fulfilling
their responsibility to give reasons for judgment, must provide public justification for
resolution of grievances that reflect and extend a coherent set of terms of interaction for
private persons. Of course, the quality of justification provided in judicial reasoning
turns on analytical properties shared by all norm-governed practical reasoning.

135 Weinrib explains that private law is a justificatory enterprise. The relationship be-
tween the parties is not merely an inert datum of positive law, but an expression ofor
at least an attempt to expressjustified terms of interaction (Idea, supra note 5 at 32).
See also Weinrib, Legal Formalism, supra note 7.

136 Zipursky, supra note 7 at 459.

1008

ture of the settled principles of liability by focusing on legal forms around
which these principles are organized (e.g., the form of legal personality,
formal qualities of kinds of legal relationship, and formal characteristics
of kinds of organization). Juridical justification is, to this extent, con-
sistent with Weinribs formalist method. The focus is on the internal
structure or internal principle of organization of legal relationships
with regard to how the components of a legal relationship stand to one
another and to the totality that they together form.137

Juridical justification involves the elucidation of coherent forms of
rightful interaction. This is important to the extent that private law is
partly constituted by discrete forms (again, forms of personality, relation-
ship, and organization). It is important, however, that one be mindful of
the limits of juridical justification. Juridical justification implies nothing
beyond the normative coherence of given bases of private liability. Contra
Weinrib, then, I do not think that juridical justification requires commit-
ment to the idea that the normative structure of private law is expressed
only in terms of corrective justice or that the only relevant measure of jus-
tice so understood is equal freedom.138 Nor does it entail the view that pri-

137 Weinrib, Idea, supra note 5 at 25. On the nature and significance of juridical reasoning
in historical context, see NE Simmonds, The Decline of Juridical Reason: Doctrine and
Theory in the Legal Order (Manchester: Manchester University Press, 1984) at 121.

138 Weinrib seems to assume that attention to the juridical character of liability is a unique
quality of corrective justice theories of private law, such that one could not be interested
in juridical justification yet be agnostic about corrective justice:

The juridical conception of corrective justice is the centerpiece of a theory
of liability. The object of the theory is to understand liability as a distinct and
familiar normative practice, in which the law assesses and responds to the
claim that a plaintiff makes against a defendant. …
Within this practice, justication has a pervasive role. The rules, con-
cepts, and principles that gure in the assessment of the plaintiffs claim are
the ingredients and the products of a justicatory process. … [T]he normative
signicance of a nding of liability depends on the cogency of the jus-
tications that support it.

The juridical conception of corrective justice takes the justicatory am-
bitions of this practice seriously by focusing on its internal normative dimen-
sion (Ernest J Weinrib, Correlativity, Personality and the Emerging Con-
sensus on Corrective Justice (2001) 2:1 Theor Inq L 107 at 113).

Other corrective justice theorists have not so readily assumed that the normative struc-
ture of private liability must be analyzed in terms of a unitary theory of justice. Com-
pare Jules L Coleman, who explains:

Political philosophy often proceeds, as it were deductively, from a set of polit-
icalmoral principles that are believed to have a claim on us, to a set of justi-
fied institutional structures. …

JUSTIFYING FIDUCIARY DUTIES 1009

vate law is an autonomous normative practice.139 It may be that the nor-
mative structure of private liability reflects considerations of distributive
or retributive justice as well as corrective justice.140 The ultimate bases of
normativity might include any number of values (e.g., equal freedom,
fairness, equality, virtue, or social welfare). The point is not that juridical
justification has no bearing on these questions. It is rather that the meth-
odology of juridical justification does not entail a position on them.

C. The Juridical Basis of Justification for Fiduciary Duties

As I explained in Part II, the entrenched position in the positive law is
that fiduciary liability is contingent on violation of duties occasioned by
the fiduciary relationship. This implies that appreciation of the nature of
the fiduciary relationship is key to understanding the justification for fi-
duciary duties.

The juridical justification for fiduciary duties treats the fiduciary rela-
tionship as a distinctive kind of legal relationship with inherent norma-
tive salience for fiduciary liability. Its salience lies in the connection be-
tween the essential characteristics or formal properties of the relationship
and the function of fiduciary duties.

The argument that there is something in the nature of the fiduciary
relationship that compels the imposition of fiduciary duties presupposes
that its formal properties can be identified. Some claim otherwise. For in-
stance, Deborah DeMott says that the characteristics of even the stand-
ard or conventional fiduciary relationships … are too varied to enable one
to distill a single essence or property that unifies all in any analytically
satisfactory way.141 John Glover questions [d]efinitional reasoning that

There are limits to the extent to which this approach can be brought to

bear systematically on the concrete particulars of law. I prefer to begin not at
the top, but in the middle, by asking what principles, if any, are embodied in
the legal practices we are presently engaged in. … We do not begin with any
presupposition about the moral status of the principles we will find. Rather,
we simply seek to identify the normatively significant elements of the prac-
tice and to explain them as embodiments of principle. … [T]he moral or justi-
ficatory questions … can grow out of the explanatory project (The Practice of
Principle: In Defence of a Pragmatist Approach to Legal Theory (Oxford: Ox-
ford University Press, 2001) at 5-6).

assumes that when the term fiduciary is applied to any type of relation-
ship, there must be a subsisting common element.142
Claims like this are understandable but not persuasive. The conclu-
sion that a concept is indefinable because it has not yet been well- or con-
vincingly defined follows an unwarranted leap of logic. Nevertheless, the
fact that fiduciary law has evolved without consensus on a definition rais-
es the question of the basis upon which one should be ventured and eval-
uated. I suggest that a definition of a juridical concept should cohere with
judicial understanding and use of the concept. The purpose of definition
is, after all, to make sense of the juridical character of liability expressed
in the concepts through which determinations of liability are made. Fidu-
ciary liability turns on relationship characterization under status- and
fact-based methods of fiduciary relationship identification.143 An effort to
define the fiduciary relationship should thus start with these methods.
Under the status-based method, the identification of a relationship as
fiduciary turns on the status of nonlegal categories of relationship. The re-
lationships conventionally recognized as
trustee-
beneficiary, agent-principal, director/officer-corporation, lawyer-client,
parent-child) are so recognized as a matter of status. Confronted with a
particular relationship, the court will categorize it and determine whether
the category enjoys fiduciary status. If so, the particular relationship is
almost always deemed fiduciary. If not, the court may consider whether a
category into which it falls merits fiduciary status. Fiduciary status is ex-
tended through loose analogical reasoning; a new category of relationship
must be found sufficiently similar to one of established status to be la-
belled as fiduciary itself. The reasoning is loose in that it is not con-
strained by agreed (and therefore authoritative) criteria of relevance.
Under the fact-based method, judges determine whether a particular
relationship is fiduciary by examining its characteristics. Here, facts about
the properties of a relationship rather than its status drive the analysis.
The most commonly cited characteristics of fiduciary relationships are

cation are flawed for reasons given elsewhere.145 Neither provides the
principled basis for ascription of liability demanded by the rule of law.146
The status-based method is not disciplined by criteria of relevance. The
fact-based method has generated widespread disagreement among judges
over the meaning and relative salience of various purported characteris-
tics of the fiduciary relationship.

I have argued that these methods should be, and at least in Canada
have been, superseded by a general conception of the fiduciary relation-
ship, defined as follows: [A] fiduciary relationship is one in which one
party (the fiduciary) exercises discretionary power over the significant
practical interests of another (the beneficiary).147 This definition draws on
the status- and fact-based methods of fiduciary-relationship identification. It
also resonates with precedent148 and with academic accounts149 that treat

144 Typically, one or more of these characteristics is mentioned in the cases. See the influ-
ential dictum of Justice Wilson of the Supreme Court of Canada, dissenting in Frame v.
Smith:

Relationships in which a fiduciary obligation [has] been imposed seem

(1) The fiduciary has scope for the exercise of some discretion or power.
(2) The fiduciary can unilaterally exercise that power or discretion so as

to possess three general characteristics:

to affect the beneficiarys legal or practical interests.

(3) The beneficiary is peculiarly vulnerable to or at the mercy of the fi-
duciary holding the discretion or power ([1987] 2 SCR 99 at 136, 42 DLR
(4th) 81).

power as an essential formal property of the fiduciary relationship. For
present purposes, I offer the definition as prima facie plausible and ask
that it be assumed sound for the sake of argument. I presently wish only
to show that it reveals a juridical basis of justification for fiduciary duties.
To appreciate how that is so, it is necessary that the definition be un-
packed.

The key implication of the definition is that the exercise of power by
one person over another is the object of the fiduciary relationship. Power
is thus the constitutive or most basic formal property of the fiduciary rela-
tionship. It has been commonly claimed that fiduciary relationships impli-
cate power. These claims, however, have not typically been elaborated at
length, and even where they have, their authors have not always appreci-
ated that power is ambiguous. Contrary to most, I maintain that fiduciary
power is not properly understood as connoting relative strength, ability,
or influence.150 Rather, it ought to be understood as a form of authority.

149 See especially Weinrib, Fiduciary Obligation, supra note 2 (the hallmark of a fiduci-
ary relation is that the relative legal positions are such that one party is at the mercy of
the others discretion at 7); JC Shepherd, Towards a Unified Concept of Fiduciary Re-
lationships (1981) 97:1 Law Q Rev 51 ([a] fiduciary relationship exists whenever any
person receives a power of any type on condition that he also receive with it a duty to
utilise that power in the best interests of another, and the recipient of the power uses
that power at 75); Frankel, Fiduciary Law, supra note 1 ([t]he second central feature
of the fiduciary relation is that the fiduciary obtains power from the entrustor or from a
third party for the sole purpose of enabling the fiduciary to act effectively at 809 [foot-
note omitted]); Smith, Critical Resource Theory, supra note 1 (fiduciaries … exercise
discretion with respect to a critical resource belonging to the beneficiary, where discre-
tion connotes the power to use or work with the critical resource in a manner that ex-
poses the beneficiary to harm that cannot reasonably be evaded through self-help at
1449); Ribstein, Are Partners Fiduciaries?, supra note 1 (a fiduciary duty is appro-
priate only where the owner delegates open-ended power to the manager at 217); Fox-
Decent, supra note 6 (arguing that fiduciary duties arise whenever one party unilater-
ally assumes discretionary power of an administrative nature over the important inter-
ests of another, interests that are especially vulnerable to the fiduciarys discretion at

aspect of their beneficiaries welfare at 126). Apart from obvious differences of detail,
my account departs from these in the way the concept of power is disambiguated (i.e.,
conceptualized as authority derived from capacities constitutive of legal personality)
and the explanation of the nexus between fiduciary power, so understood, and fiduciary
duties.

More specifically, fiduciary power is a form of authority derived from ca-
pacities that are constitutive of the legal personality of another individual
or group of individuals. I contend that power is a constitutive formal
property of the fiduciary relationship only in this sense.

The claim that power is a constitutive formal property of the fiduciary
relationship has formal and practical implications. The formal implica-
tions are that power is a more fundamental formal property of the fiduci-
ary relationship than any of its other formal properties. The most im-
portant practical implication is that possession of power is the basis on
which particular relationships may be identified as fiduciary.
Given that the concept of fiduciary power is derived from a more gen-
eral concept of power, its disambiguation bears further analysis. I will
clarify the meaning of authority first, as this will allow for discussion of
other formal properties of the fiduciary relationship. Legal capacity, being
the specific form of authority at stake in fiduciary relationships, will be
analyzed at greater length in Part V.D, below.
Most abstractly, authority goes to the rightful character of the conduct
of one person toward another. Rightfulness is at issue for conduct poten-
tially inconsistent with the legal status or rights of another. Authority can
render rightful conduct that would otherwise be wrongful. Fiduciary pow-
er is authority so understood. But many people have authority in this
sense and are not thus considered fiduciaries. Fiduciary authority has
three further qualities. First, it is discretionary in nature. Discretion en-
tails latitude for judgment by the person invested with authority in de-
termining its exercise. Second, fiduciary authority is relational and deriv-
ative. Fiduciaries do not enjoy a form of sovereign authority. Rather, they
enjoy authority in relation to a specific individual or group and derive
their authority from a legal capacity or set of capacities of that individual
or group or from a benefactor of the individual or group (i.e., a private
third party or the state).151 Third, fiduciary authority is specific. Fiduciar-
ies do not have plenary power. Rather, their authority is specified (and so
limited) by grant or undertaking of authority or otherwise by law.

Partners Fiduciaries?, supra note 1 at 215-18 (equating power with managerial control
over property).

151 Consider the relationship between agent and principal. Authority inheres in the con-
cept of agency. An agent is one who has the authority to make legally binding decisions
on behalf of a principal, ordinarily in respect of contractual matters. The agent derives
that authority from an express or implied grant of authority by the principal. The prin-
cipal is capable of conferring authority on the agent because the authority in question is
simply an extension of the legal capacity the principal has by virtue of her legal person-
ality; in this case, the capacity to enter into legally binding contractual relationships
with others.

1014

The relational and derivative nature of fiduciary authority gestures at
the position of the beneficiary in the fiduciary relationship. Fiduciaries
wield discretionary authority relative to significant practical interests of
beneficiaries and derive that authority from another person. That person
is typically the beneficiary, but in rare cases, it may be a benefactor such
as the state (e.g., delegating power in loco parentis over a child) or a pri-
vate third party (e.g., a settlor establishing a trust for the benefit of
named beneficiaries). A beneficiarys interest is practical where it con-
notes a real, ascertainable matter of personality, welfare, or right suscep-
tible to the exercise of authority by another. Matters of personality in-
clude aspects of the personality of corporate or natural persons who lack
legal capacity, including the determination of their ends.152 Matters of
welfare include decisions bearing on the physical and psychological integ-
rity and well-being of natural persons.153 Matters of right include deci-
sions bearing upon the interests of corporate and natural persons relative
to their legal rights, duties, powers, and liabilities, including those in rela-
tion to contract and property.154 As I will explain in Part V.D., below, what
unites matters of personality, welfare, and right is that they are matters
for decision making ordinarily within the exclusive legal capacity of the
person granting authority to the fiduciary.

Power is vested in fiduciaries to enable them to act for, or on behalf of,
beneficiaries, or to otherwise serve their interests. Fiduciary power is thus
a means by which to achieve the ends of beneficiaries. Power is a means
in two senses. First, it may be exercised to pursue ends of the beneficiary
that engage her practical interests. Second, it may be exercised in setting
or determining ends of the beneficiary that engage her practical interests.
Established fiduciary relationships have structural properties that re-
flect the nature of fiduciary power as a distinct form of authority. It is
commonly said that fiduciary relationships are characterized by inequali-
ty, dependence, and vulnerability. These characteristics are best under-
stood as structural properties shared by all fiduciary relationships subse-
quent to relationship formation. Wherever one person enjoys fiduciary
power over another, their relationship will be asymmetrical in respect of
the power itself. The salient inequality lies in the enjoyment by the fidu-
ciary of a particular authority that the beneficiary lacks (regardless of
whether authorization may be rescinded). The pertinent forms of depend-

152 For example, the capacity to determine the objects to be pursued by business or non-

profit corporations.

153 For example, the capacity to determine a persons medical or psychiatric treatment.
154 For example, the capacity to enter into contracts on behalf of another person, to exercise
or waive contractual rights, to manage property, or to exercise or enforce rights in prop-
erty.

JUSTIFYING FIDUCIARY DUTIES 1015

ence and vulnerability simply reflect this inequality. Where effective, au-
thority entails influence, including the risk of adverse influence. The ben-
eficiary is invariably dependent upon the fiduciary as power is exercised
to affect her practical interests. The beneficiary is likewise invariably vul-
nerable to the fiduciary as power may be abused, misused, or exercised
carelessly with prejudice to the beneficiarys interests.

The nature of fiduciary power is also significant for our understanding
of modes of fiduciary-relationship formation. Given that fiduciary power is
a form of authority derived from the legal capacity of another person, the
critical matter in determining how fiduciary relationships may be formed
is to identify ways in which one person may be invested with authority in
this sense over another. At the highest level of generality, authority may
be conferred or undertaken, or both. Depending on the circumstances, it
may be conferred by law or by the consent of an individual.155 Ordinarily,
given that fiduciary power is authority derived from the legal capacity of
another person, it must be conferred by some manifestation of consent of
the person from whose capacity it is derived. However it arises, conferral
of authority usually requires acceptance to be effective.156 Often, conferral
and acceptance will be evidenced in an agreement.157 Rarely, conferral
might be effectuated by mandatory imposition of the state, in which case
acceptance is not required.158 Finally, in the rare case that express confer-
ral is unnecessary or impossible, authority may arise upon an undertak-
ing by the fiduciary.159 All of this is to say that the formation of fiduciary
relationships is accomplished through valid investiture of authority in the
fiduciary by cession (or conferral otherwise) of legal capacity by the bene-
ficiary or a benefactor.160

155 For example, the authority enjoyed by parents over children is conferred by law; the au-

thority enjoyed by agents over principals is conferred by consent.

156 For example, a parent may place a child for adoption or refuse to recognize and take

custody of the child; a physician cannot be forced to accept a patient for treatment.

157 As in articles of incorporation, medical consent forms, legal retainers, and agency con-

tracts.

158 For example, a parent need not expressly assent to the investiture of authority over a

biological child.

159 For example, administration of emergency treatment by a physician to an incapable

adult without a surrogate.

160 The modes of investiture described here are consistent with Justice Dicksons observa-
tion in Guerin that fiduciary relationships may be established by statute, agreement,
or perhaps by unilateral undertaking (supra note 26 at 384).

D. Elements of the Juridical Justification for Fiduciary Duties
The character of fiduciary liability is such that a successful response

to the problem of justification must address the connection between fidu-
ciary relationships and fiduciary duties. The juridical justification holds
that the duty of loyalty is best understood in terms of normatively salient
formal properties of the fiduciary relationship.

The juridical justification for fiduciary duties has four parts, each of
which goes to the normative import of the fiduciary relationship for fidu-
ciary liability. First is an account of the constitutive formal properties of
the fiduciary relationship. Second is an explanation of the import of struc-
tural formal properties of the fiduciary relationship. Third is a discussion
about the significance of these properties to our understanding of the
normative status of the fiduciary relationship. Last is the argument of
justification proper, in which reasons for liability are located in the nor-
mative status of fiduciary power.

The constitutive formal properties of the fiduciary relationship, as re-
flected in the definition provided in Part V.C, are the exercise of discre-
tionary power by the fiduciary over practical interests of the beneficiary.
Power is the most basic of the constitutive properties of the fiduciary rela-
tionship; the practical interests of the beneficiary are the focal point or
ground of fiduciary power, entailed by its relational character. The mean-
ing of these properties hints at their normative salience. Fiduciary power
is a form of legal authority. Normative import therefore inheres in it.
Where it is validly invested and held, authority legitimates conduct that
would otherwise be illegitimate or positively wrongful.161 It therefore al-
ters the normative conditions under which people interact. Authority en-
ables the bearer to perform functions and to make decisions that would
not otherwise be open to her. It also legitimates the subjection of others to
decisions validly made pursuant to the performance of these functions.162
Specifically, in the case of fiduciaries, authority enables the fiduciary to
exercise legal capacities that, being derived from another person, would
ordinarily be the beneficiarys or benefactors alone to exercise. Exercise
by the fiduciary of the legal capacity of another person entails their sub-
jection to her will (i.e., the beneficiary or the benefactor from whose legal
personality the capacity is derived is subject to the decision of the fiduci-
ary in the exercise of that capacity).

161 Validity here refers to proper investiture of authority.
162 Validity here goes to the proper exercise of authority (notably, that a decision taken un-
der the guise of authority is valid in the sense of being intra vires and made for a proper
purpose).

JUSTIFYING FIDUCIARY DUTIES 1017

The relational and derivative character of fiduciary power specifies
further the normative effect of the transformation. Fiduciary power is a
form of authority wielded by the fiduciary relative to the beneficiary. As
such, it transforms the terms on which fiduciary and beneficiary specifi-
cally interact. Fiduciary power enables the fiduciary to do things to or for
the beneficiary that she would otherwise be prohibited from doing, inas-
much as it entails her exercise of legal capacities of the beneficiary or
those of a benefactor relative to the beneficiary. In any given relationship,
the mandate under which a fiduciary acts may include the power to de-
termine the ends of a beneficiary, to make decisions affecting her person
or property, or otherwise to alter, assume, or determine her legal rights,
duties, powers, and liabilities.163

The nature of fiduciary power as a form of authority derived from the
legal capacity of another person therefore has fundamental normative
significance.164 Fiduciary power does not simply legitimate conduct that
would otherwise be wrongful; it legitimates a limited form of substitution
of legal personality.165 Again, fiduciary powers are legal capacities derived
from the legal personality of other persons, natural or corporate (e.g., ca-
pacities to make or perform contracts or to manage, sell, or invest proper-
ty).166 In wielding them, the fiduciary stands in substitution for that per-
son within the ambit of the power.

The discretionary character of fiduciary power goes to the effect of the
substitution. In exercising another persons legal capacity, the fiduciary is
not a mere proxy. The exercise of authority by the fiduciary is not subject
toand, in some cases, is not susceptible ofdictation. Its scope may be

163 For example, by exercising contractual or property rights on behalf of the beneficiary or
by effectuating the donative intent of a benefactor in respect of property in which the
beneficiary has an equitable property interest.

164 The capacity is almost always that of the beneficiary. The capacity, however, may in-
stead be that of a private or public benefactor (i.e., the state or a third party). Consider
the express trust, where trust property is advanced by a settlor for the benefit of a
third-party beneficiary. The trust exists to effectuate the donative intent of the settlor,
and the capacities exercised by the trustee to that end are those of the settlor. The bene-
ficiary is entitled to the beneficial exercise of those capacities consistent with the dona-
tive intent of the settlor in respect of the disposition of trust property.

165 This is the sense in which it is right to speak of the fiduciary as a substitute. See
Frankel, Fiduciary Law, supra note 1 ([a] central feature of fiduciary relations is that
the fiduciary serves as a substitute for the entrustor at 808); Criddle, supra note 6
([t]he starting point for all fiduciary relations is substitution at 126).

166 On the nature of legal personality in general, see Max Radin, The Endless Problem of
Corporate Personality (1932) 32:4 Colum L Rev 643 (describing the conventional view
that legal personality, like the personality of an ordinary man, can be exhaustively de-
scribed in the list of rights and capacities which come into practical being only … when
the individual performs certain specified acts in a certain specified way at 645).

(2013) 58:4 MCGILL LAW JOURNAL ~ REVUE DE DROIT DE MCGILL

1018

defined by instructions or limited by express retention of power. Never-
theless, within the scope of vested authority, the fiduciary is free to exer-
cise judgment in determining whether, when, and how it is to be acted
upon.167 To that extent, the fiduciary has the capacity not merely to effec-
tuate the will of the beneficiary or benefactor, or both, but to subject them
to her will.

The specificity of fiduciary power reveals the circumscribed nature of
its substitutive effect. The fiduciary does not overtake the personality of
the beneficiary. This is true even where the fiduciary has broad authority
to determine the ends of an incapable person, such as a child or corpora-
tion. Instead, the fiduciary exercises a particular legal capacity or range of
capacities.168 Exercise of these capacities may further be specified tempo-
rally or as to subject matter. The authorization under which a fiduciary
acts may specify a term.169 It might also stipulate the subject matter in re-
lation to which authority is held.170 The ability of the fiduciary to legiti-
mately subject the beneficiary or benefactor, or both, to her will is there-
fore circumscribed. The fiduciary determines matters of choice only within
the ambit of authority under which she acts.
As explained in Part V.C, the structural properties of the fiduciary re-
lationship speak to the relative positioning of the fiduciary and benefi-
ciary. I have said that there are three related structural properties of the
fiduciary relationshipinequality, dependence, and vulnerability. These
properties are normatively significant for the purposes of fiduciary liabil-
ity only insofar as they represent the formal structural implications of the
establishment of a fiduciary relationship for the parties to it.

Inequality of power inheres in the fiduciary relationship in that the fi-
duciary is vested with authority over the beneficiary. This inequality is
not necessarily counterbalanced by reciprocal investment of power in the
beneficiary.171 Accordingly, the fiduciary relationship has an asymmetrical

167 See Weinrib, Fiduciary Obligation, supra note 2 ([t]he reason that agents, trustees,
partners, and directors are subjected to the fiduciary obligation is that they have a lee-
way for the exercise of discretion. … [I]f they have no discretion to advise or negotiate
and if their instructions are narrow and precise there is nothing on which the fiduciary
obligation can bite at 7).

168 For example, a trustee has authority to manage or administer trust property, but no

authority to personally bind the settlor or beneficiary in contract.

169 For example, children attain authority implicit in legal capacity at a specified age of

majority.

170 For example, the authority of directors and officers of corporations may be limited to the

pursuit of objects specified in enabling legislation or articles of incorporation.

171 Though it is, in some cases, such as in partnerships, which are carried out on the basis

of reciprocal agency relationships between partners.

JUSTIFYING FIDUCIARY DUTIES 1019

formal structure. The fiduciary is, simply by virtue of the establishment of
the relationship, in a dominant position relative to the beneficiary and, in
some cases, the benefactor.
Dependence inheres in the fiduciary relationship given that fiduciary
power entails influence. Fiduciary relationships enable one person to ex-
ercise the legal capacity of another relative to a beneficiarys practical in-
terests. Decisions made by the fiduciary will ordinarily influence practical
interests of the beneficiary (in a salutatory way, it is hoped). To the extent
that fiduciary power entails influence, it establishes dependence.
Vulnerability follows in that the influence associated with fiduciary
power entails risk. The fiduciary is expected to exercise power for the
benefit of the beneficiary, but that expectation may be disappointed. The
fiduciary may neglect the interests of the beneficiary or may prefer her
own interests or those of a third party.
Having discussed the constitutive and structural properties of the fi-
duciary relationship, I am now better positioned to consider the normative
implications of these properties for fiduciary liability. Fiduciary power is
substitutive. The fiduciary exercises a legal capacity of another person in
setting or pursuing practical interests of the beneficiary. Legal capacities
are integral to the actual capacity of a person to set and pursue her ends.
These capacitiesto contract, to inherit, to establish a trust, to establish
possessory interests in propertyare the very means by which individu-
als act purposively through law. Fiduciary power, and by extension the fi-
duciary relationship, thus enables one person to act purposively on behalf
of another. The ability to confer fiduciary power and so to establish a fidu-
ciary relationship enhances the beneficiarys or benefactors ability to ef-
fectively pursue her purposes, for it enables her to draw upon a fiduciarys
means (e.g., skills, knowledge, experience, professional licensure) in the
exercise of her capacities.

The purpose for which fiduciary power is held is implicit in its substi-
tutive nature. It is rendered explicit in the innumerable authorities that
hold that fiduciaries are to act in the interests of beneficiaries.172 This re-
quirement is not itself imposed by way of enforceable legal duty.173 It is
best understood as expressing the normative status of fiduciary power.
Fiduciary power, being derived from capacities constitutive of the legal
personality of another person, cannot but be understood as an extension
of that other persons personality. It is partly through their legal capaci-

172 See supra notes 17-18.
173 But see Birks, Content of Obligation, supra note 15. See Conaglen, Fiduciary Loyalty,

Obligations (2010) 21:3 Kings Law Journal 333.

1020

ties that persons are recognized as such in private law (i.e., as purposive
beings, with standing to act in ways permitted or facilitated by law). Fidu-
ciary power, being an extension of the legal personality of the person from
whose capacity it is derived, is thus properly understood as a meansthat
is, a way of effectuating ones purposesbelonging rightfully to the bene-
ficiary. Fiduciary power is a means of a beneficiary even where it is de-
rived from the personality of a benefactor, for the effect of the benefaction
is devotion of the power to the beneficiarys ends. To say, as courts rou-
tinely do, that fiduciaries are to act in the interests of the beneficiary is
simply to assert as normatively controlling the status of fiduciary power
(i.e., its status as a constituent element of the personality of the benefi-
ciary or benefactor) and the purpose for which fiduciary power is held (i.e.,
to enable the determination or pursuit of the ends of the beneficiary).

This permits clarification of the justification for fiduciary duties. Giv-
en that fiduciary power is a means of the beneficiary, the interaction be-
tween fiduciary and beneficiary must be presumptively conducted for the
sole advantage of the beneficiary. Fiduciary power, as a means derived
from or devoted to the beneficiary, is held for the advancement of the ben-
eficiarys ends alone. A fiduciary relationship may be formed by contract
and so coincide with expectations of mutual advantage. But within the fi-
duciary relationship, the fiduciary is to serve the interests of the benefi-
ciary.174 Fiduciary duties help to ensure that fiduciary power is exercised
in a manner consistent with its status and purpose.

The conflict rules constitutive of the duty of loyalty constrain fiduciar-
ies in the exercise of fiduciary power. Specifically, the conflict of interest
rule prohibits fiduciaries from exercising fiduciary power in self-interest.
The conflict of duty rule prohibits fiduciaries from exercising fiduciary
power in the interests of third parties under a conflicting mandate. The
juridical reasons for imposing the duty of loyalty follow from what we

174 Contracts are both a mode of authorization and the basis on which consideration is paid
for the value of means to be employed by the fiduciary (e.g., professional qualifications,
skill, etc.). The fiduciary relationship is distinguishable as the purposive interaction
through which ends of the beneficiary are pursued through the exercise of power by the
fiduciary. The claim that the fiduciary relationship is presumptively to be conducted for
the sole advantage of the beneficiary is consistent with limited allowances for self-
interested conduct by fiduciaries. Such conduct is countenanced where ex ante or ex post
authorization makes clear that it was intended that the fiduciary share personally in
gains arising through the exercise of fiduciary power. In these circumstances, the per-
son authorizing the fiduciary to act partially alienates fiduciary power as a means at
her disposal. Courts strictly scrutinize the terms of the authorization and, where it was
given ex post, the circumstances under which it was offered, precisely because allow-
ances for self-interested conduct are inconsistent with the assumption that fiduciary re-
lationships are, by their very nature, established for the exclusive benefit of beneficiar-
ies.

JUSTIFYING FIDUCIARY DUTIES 1021

have said about the juridical character of the fiduciary relationship and,
particularly, what we have said about the status of fiduciary power, its
most basic constitutive formal property. The content of the duty of loyalty
is a direct reflection of the normative status of fiduciary power. The con-
flict rules proscribe appropriation by the fiduciary of fiduciary power un-
derstood as means belonging exclusively to the beneficiary. The fiduciary
may not treat fiduciary power as an unclaimed means or as a personal
means. The duty of loyalty secures the beneficiarys legitimate expectation
that fiduciary power, as one of her means, will be used only to achieve her
ends. The wrongful character of fiduciary disloyalty is the same regard-
less of whether the conduct of the fiduciary is self- or other-regarding; in
either event, the fiduciary has treated fiduciary power as a means at his
disposal and, in doing so, has violated the beneficiarys exclusive claim
upon the disposition of her means.

E. Revisiting the Problem of Justification

The juridical justification locates reasons for fiduciary duties in the
nature of the fiduciary relationship and judicial assertions of the norma-
tive status of its most basic constitutive formal propertyfiduciary power.
Fiduciary power is a kind of authority derived from legal capacities inte-
gral to the legal personality of the beneficiary or benefactor. As an exten-
sion of the legal personality of the beneficiary or benefactor, fiduciary
power is properly understood as a means belonging rightfully to the bene-
ficiary (either by original status or through benefaction). The duty of loy-
alty ensures that fiduciary power is exercised in a manner consistent with
its status by proscribing its appropriation by the fiduciary. The fiduciary
may not treat fiduciary power as an unclaimed means. By regulating the
ends for which fiduciary power may be exercised, the duty of loyalty does
not guarantee satisfaction of the particular ends of beneficiaries in partic-
ular fiduciary relationships. It does, however, secure the exclusivity of
their claim upon fiduciary power as a means to be applied to their ends.

The juridical justification for fiduciary duties does not offer whatever
additional justificatory power may be found in normative moral or politi-
cal theory. But that is an intentional concession made necessary by my
aim for modest normative claims that prioritize consistency with the ju-
ridical character of fiduciary liability. Juridical justification is not incon-
sistent with philosophical justification. Rather, as a precondition of sound
philosophical analysis, it simply leaves the question of the philosophical
justification open.
The juridical justification fits well with thin and thick descriptions of

fiduciary liability. Recalling the thin description provided in Part II, it is
clearly consistent with the conventional view that fiduciary liability is
contingent on the establishment of a fiduciary relationship. The juridical

(2013) 58:4 MCGILL LAW JOURNAL ~ REVUE DE DROIT DE MCGILL

1022

justification locates reasons for liability in the nature of the fiduciary rela-
tionship. In doing so, it offers support for the assumptions implicit in
practice that the fiduciary relationship is a distinctive kind of legal rela-
tionship and that fiduciary duties reflect properties of the fiduciary rela-
tionship so understood.
The juridical justification also fits well with the thick description of fi-

duciary liability that emerged over Parts III and IV. It is capable of ex-
plaining features emphasized by the argument from contract. First, it ac-
cepts that most fiduciary relationships are established consensually. Of-
ten, but not always, consent will be manifested in contract. Consent and
contract are modes of authorization going to relationship formation. Sec-
ond, it can accommodate the insight that fiduciary duties sometimes con-
strain the performance of contractual undertakings. Where conferred by
contract, fiduciary power is typically subject to terms expressed contrac-
tually. These terms at once define the ambit of fiduciary power and gen-
erate a contractually enforceable obligation that power be exercised as
agreed. Third, it is consistent with limited consensual exclusion of fiduci-
ary liability. Fiduciary power is presumptively exercised for the sole bene-
fit of the beneficiary. But the beneficiary may decide to partially alienate
her means. Consent grounds limited departure from the conflict rules pre-
cisely because fiduciary power is a means belonging rightfully to the bene-
ficiary.

The juridical justification also embraces insights of the argument from
property. First, it is consistent with the claim that fiduciaries often have
control over property owned by beneficiaries. Where fiduciary power is
held in relation to property, the fiduciary is properly understood as exer-
cising the legal capacity of another (the beneficiary or benefactor) in re-
spect of it. Owners have authority over property secured by legal rights of
ownership, including the right to manage it, to control its disposition, and
to determine its use.175 Ownership rights may be exercised personally by
the owner or by a fiduciary acting as a substitute. But ownership interests
are just one kind of practical interest over which fiduciary power may be
exercised. Second, the juridical justification can account for the fact that
fiduciary duties often prevent misapplication and misappropriation of
property. Fiduciary power over property entails the risk of diversion of the
property or its fruits. This is but an example of fiduciary disloyalty. The
primary function of the duty of loyalty is to secure the exclusivity of the
beneficiarys claim on power as a means, whatever the nature of the un-
derlying interest.

JUSTIFYING FIDUCIARY DUTIES 1023

Finally, the juridical justification addresses well the insights that mo-
tivated the argument from nonfiduciary law. First, it allows for concur-
rent liability and explains how it may arise. Depending on material facts
relating to the nature of the power conferred, the mode of authorization
through which the fiduciary relationship is formed, and the manner in
which the fiduciary mandate is executed, fiduciary duties will frequently
arise concurrently with nonfiduciary duties. But the concurrence is a con-
tingent matter. Fiduciary duties are not called forth by nonfiduciary du-
ties or vice versa. Second, it recognizes that fiduciary duties are premised
on an expectation of performance. Fiduciaries are expected to exercise
power to set or pursue the practical interests of beneficiaries. Exercise of
power is the material kind of performance. Compliance with nonfiduciary
duties is not, and for good reason; expectations of performance of nonfidu-
ciary duties are secured by nonfiduciary principles of liability.

Conclusion

Fiduciary duties govern relationships of great personal and social im-
portance. Fiduciary relationships are a distinctive form of relationship
through which myriad individual and joint ends are advanced. They range
from interpersonal to institutional, undergirding family life, our interac-
tions with most professionals, and the productive activities of many or-
ganizations. Notwithstanding their importance, the justification for fidu-
ciary duties has been underanalyzed. Leading arguments employ reduc-
tivist and instrumentalist analytical strategies. Neither has yet produced
convincing results, but both have generated arguments that highlight im-
portant aspects of fiduciary liability. The resulting enriched perspective
on fiduciary liability points to a more promising avenue of justification.

That avenue is juridical. The juridical justification offered here holds
that fiduciary duties are distinctive and supported by reasons derived
from formal properties of the fiduciary relationship. In fiduciary relation-
ships, one person (the fiduciary) exercises discretionary power over the
practical interests of another (the beneficiary). Fiduciary power is a form
of authority derived from the legal capacity of the beneficiary or a bene-
factor. The normative status of fiduciary power is that of a means belong-
ing exclusively to the beneficiary. The duty of loyalty secures this status
by prohibiting the fiduciary from treating fiduciary power as an un-
claimed means.
