CHAPTER 6
CONFLICT OF INTEREST
A. INTRODUCTION
A conflict of interest occurs whenever a lawyer is placed in a position
where loyalty to a client is compromised. There are an inexhaustible
number of situations in which a conflict problem can arise. The con-
flicting interests may involve current, former, or prospective clients,
and sometimes even third parties with whom a client-lawyer relation-
ship is never established or contemplated. A lawyer’s loyalty may also
be compromised by her own interest or the interest of an affiliated law-
yer. Categorizing scenarios according to the type of conflict raised is
a helpful way to address the ethical and legal obligations of criminal
counsel in this area. A discussion of any particular scenario, however,
is incomplete without examining the principles that make conflict
avoidance so important, as well as the professional-conduct standards,
common law rules, and constitutiona l guarantees that are derived from
and reflect these principles.
B. BASIC PRINCIPLES
The client-lawyer relationship is based on the highest of trusts, where
the lawyer’s loyalty is unquestioned. The duty to be loyal, born of the
fiduciary relationship between counsel and client, guides and informs
ETHICS AND CRIMINAL LAW264
every aspect of the lawyer’s dealing with a client.1 It underpins import-
ant related obligations such as the duty of confidentiality. As we shall
see, the duty of confidentiality i s particularly important in the real m of
conflict of interest. Yet a threat to confidentiality is not a precondition
to the existence of a conflict problem. The leitmotif of conflict of inter-
est is the broader duty of loyalty.2 Where the lawyer’s duty of loyalty is
compromised by a competing interest, a conflict of interest will exist
even when there is no possibility that confidential information will be
misused.
The importance of loyalty to the client-lawyer relationship is under-
lined by the adversarial nature of the criminal justice system. An ad-
versarial system gives litigants the right and responsibility to present
their own cases and to challenge the evidence and arguments of their
opponents. As agents for the litigants, lawyers operate within this ad-
versarial sett ing, making loyalty towards the client absolutely essential
— a lawyer must act as zealous advocate for the client’s cause.3 Failure
to provide loyal service may harm the client’s ability to exercise im-
portant constitutional rights.4 It can also undermine the reliability of a
result and the public’s confidence in the legal process.
The duties necessary for a healthy client-lawyer relationship are
thus, by extension, funda mental to the entire administ ration of justice.5
It follows that guarding against conflict of interest prevents harm to
both the client and the criminal justice system.6

C. RELATED RULES OF PROFESSIONAL
CONDUCT
Many rules of professional conduct emphasize the principles driving
the proscription against conflict of interest. Most importantly, Canadian
governing bodies have adopted comprehensive rules that specifically
address conflict issues.7 The content of these rules is discussed exten-
sively throughout this chapter. For now, suffice it to say that they rec-
ognize that the client’s interests and the administration of justice more
broadly may be seriously impaired when a lawyer’s judgment and abil-
ity to act on the client’s behalf is not free from compromising i nfluences.
Other rules of professional conduct furt her reflect the concerns raised
when a lawyer confronts a possible conflict of interest, for instance
1) Integrity: Lawyers are required to discharge with integrity all dut-
ies owed to a client, the court, the public, and other members of
the profession.8 Integrity is the fundamental quality of a lawyer,9
representing a key element of each rule of professional conduct,
and from the perspective of the client finds expression in absolute
trustworthiness.10 Trustworthiness, or loyalty, is seen to be the es-
sential element of the client-lawyer relationship.11
2) Confidential information: A lawyer has a duty to hold in strict con-
fidence all information concerning the business and affairs of the
client acquired in the course of the professional relationship.12 The
information cannot be used for the benefit of the lawyer or a third
party, or to the detriment of the client,13 and this duty per sists even
after the professional relationship ends.14
