Conflict of Interests: Previous Representation of Witness in Unrelated
An attorney may represent a defendant in a criminal case, even though
another attorney in his or her office formerly represented an individual
who is now a witness in that case if (1) the agency’s representation
of the person who is the witness was in an unrelated case; (2) the attorney
involved in the current case does not actually possess any confidences
or secrets of the former client; and (3) the agency takes adequate steps
to screen that attorney from any such confidences and secrets.
- Rule 1.6 (Confidentiality of Information)
- Rule 1.7 (Conflict of Interest: General Rule)
- Rule 1.9 (Conflict of Interest: Former Client)
- Rule 1.10 (Imputed Disqualification)
The Public Defender Service (PDS) has requested an opinion about the
responsibilities of its attorneys in the following situation: PDS Attorney
#1 represented Client #1, who was a defendant in a Burglary case. This
case is now closed. PDS Attorney #2 is appointed to represent Client #2
in a separate Assault case. Attorney #2 discovers that Client #1 is the
complainant or an essential government witness. Attorney #2 learned about
this possible conflict in a way other than through discussions with Attorney
#1 (e.g., by checking the court file or from discussions with the U.S.
Attorney or with witnesses).
PDS has represented that if Attorney #2 is allowed
to continue to represent Client #2, it will screen Attorney #2 from any
information about Client #1 by preventing him or her from having access
to Client #1’s files and from discussing the case with Attorney #1.
The Public Defender Service’s inquiry raises the issues of: (1) whether
there is a conflict of interest between the representation of the former
client and the new client; and (2) the extent to which an attorney representing
a new client will be subject to imputed disqualification because another
attorney in the same office represented the former client.
Since the inquiry presumes the involvement of
two attorneys, the analysis of the issues raised must begin with an understanding
of the requirements of Rule 1.10. In general, this Rule prohibits one
attorney in a “firm” from undertaking any matter for which any
other member of the firm would be disqualified. The Commentary to Rule
1.10 states that the term “firm” encompasses legal services
agencies. See Comment 1.1
Assuming that the attorneys at PDS are the equivalent of “lawyers
[who] are associated in a firm,” Rule 1.10(a) specifies that none
of the agency’s attorneys “shall knowingly represent a client when
any one of them practicing alone would be prohibited from doing so by
Rules 1.7, 1.8(b), 1.9, or 2.3.”
Because the issue in this case is whether there
is a conflict of interest involving a former client, Rule 1.9 applies.
This Rule states:
A lawyer who has formerly represented a client in a matter shall
not thereafter represent another person in the same or a substantially
related matter in which that person’s interest are materially adverse
to the interest of the former client unless the former client consents
Thus, Attorney #2 cannot represent Client
#2 if his or her case is the “same” or “substantially related”
to the case in which Attorney #1 represented Client #1. Under the facts
set forth by PDS here, however, the representation of Client #1 was in
Client #1’s own case—not as a participant in case #2. These two
representations are clearly not in the “same matter.”2
The more difficult question is whether the two
representations are in “substantially related” matters. The
Rules do not define “substantially related,” other than to note
that Rule 1.9 was “intended to incorporate federal case law”
that defines the term. Rule 1.9, Comment 2. For guidance, the commentary
points to T.C. Theatre Corp. v. Warner Brothers Pictures, Inc., 113 F.
Supp. 265 (S.D.N.Y. 1953), aff’d, 216 F.2d 920 (2d Cir. 1954), and “its
The difficulty with this direction, however,
is that the definition provided by this case law is still uncertain.
In Brown v. District of Columbia Board of Zoning
Adjustment, 486 A.2d 37 (D.C. 1984), the Court of Appeals indicated that
the methodology to be used “for determining whether two matters are
substantially related” begins with an analysis of the facts and legal
issues to determine, in the first instance, whether the factual contexts
of the two matters overlap. If they do, further analysis is required.
486 A.2d at 49; see also Westinghouse Electric Corp. v. Gulf Oil Corp.,
588 F.2d 221, 225 (7th Cir. 1978).
In the facts as set forth by PDS, the subject
matter of the two representations are not the same or substantially related.
Thus, under Rule 1.9, Attorney #2 should be able to continue to represent
Even if Rule 1.9 is satisfied, however, Rule
1.6 may prohibit the subsequent representation of Client #2 if Attorney
#2’s representation would violate any of Client #1’s confidences or secrets.
Rule 1.6 prohibits a lawyer from knowingly “us[ing] a confidence
or secret of the lawyer’s client to the disadvantage of the client . . .
[or] for the advantage of the lawyer or of [another].”
Under the facts here, in all likelihood, Attorney
#1 possesses confidences or secrets of Client #1 that might be helpful
to Client #2, but Attorney #2 does not personally possess such information.
Unlike the proscriptions of Rule 1.9, Rule 1.10 does not impute a disqualification
to Attorney #2 based on Rule 1.6.
Comment 11 to Rule 1.10 explains that preserving
confidentiality turns on the issue of whether there has been “an
access to information” about a specific client. This issue, in turn,
depends on the “fact[s] in particular circumstances.” The commentary
notes that some lawyers have general access to the files of all clients
in the firm, and some do not. It concludes that “in the absence of
information to the contrary, it should be inferred that such a lawyer
in fact is privy to information about the clients actually served and
not those of other clients.” See also Brown, 486 A.2d at 42, n. 5.
In this case, Attorney #2 has not received any
confidential information from Attorney #1 or Client #1’s confidential
files. The Public Defender Service has represented that when one of its
attorneys learns that a past client may be a witness against a current
client, an attorney supervisor will take custody of the past client’s
files and secure them in a locked file cabinet to which Attorney #2 does
not have access. Both Attorneys #1 and #2 are instructed that they may
not discuss their cases or clients with each other or in each other’s
presence. These efforts are consistent with the proscriptions of ABA Formal
Opinion 342 (1975) and Brown, 486 A.2d at 42. Thus, Rule 1.6 will not
serve to disqualify Attorney #2 since he or she has not actually gained
confidential information nor will he or she be exposed to it.
Consistent with Rule 1.4, Client #2 should be
informed about the fact that PDS represented the witness against him at
an earlier point and the limitations on Attorney #2’s ability to use any
of Client #1’s confidences or secrets that the office might have in its

- the Commentary also notes that
“whether the lawyers should be treated as associated with each
other can depend on the particular rule that is involved, and on the
specific facts of the situation” (see Comment 3), in the circumstances
presented in this case, the result will be the same whether or not the
Public Defender Service is treated as a “firm.”

Client #2 if he or she represented #1 in his capacity as a witness in
the Assault case. See Opinion No. 232.
- may be some who may detect “an
appearance of impropriety” in the public defender service’s
attempt to impeach a former client. This standard is no longer found
in the Rules of Professional Conduct. Rather, the Rules specify what
conduct is allowed and what is not. Moreover, even if this standard
still existed, it is “too slender a reed” to require disqualification.”
