OPINION 2022-04
Issued June 10, 2022
Withdraws Adv. Op. 1988-15
Imputation of County Prosecuting Attorney’s Former Client and Firm Conflicts to an
Assistant Prosecuting Attorney
SYLLABUS: Absent informed written consent, a county prosecuting attorney must
appoint an assistant prosecuting attorney to handle cases that were assigned to the public
defender’s office during the county prosecuting attorney’s former employment with the
office and implement appropriate screening measures if the county prosecuting attorney
(1) personally represented the defendant in the same or substantially related matter, or
(2) obtained protected information about other clients of the public defender’s office.
QUESTION PRESENTED:
May a county prosecuting attorney, who previously served as the county public
defender, appoint an assistant prosecuting attorney to handle cases that were assigned to
the public defender’s office during the county prosecutor’s former employment?
APPLICABLE RULES: Prof.Cond.R. 1.7, 1.9, 1.11.
OPINION:
An examination of the county prosecuting attorney’s conflicts of interest must be
conducted prior to addressing the imputation question posed.

Op. 2022-04 2
Former Clients of the Prosecuting Attorney
Prof.Cond.R. 1.11(d)(1) obligates a county prosecuting attorney to abide by the
general conflict of interest provisions of Prof.Cond.R. 1.9 regarding former clients. If the
county prosecuting attorney formerly represented a defendant in the same or a
substantially related matter while employed at the public defender’s office, then the
prosecutor is prohibited from prosecuting the defendant in the same or substantially
related matter unless both the defendant and the government agency give informed
written consent. Prof.Cond.R. 1.9(a) and 1.11(d)(2)(i). A “substantially related matter” is
defined as one that involves the same transaction or legal dispute or one in which there
is a substantial risk that confidential factual information normally obtained in that type
of matter would materially advance the position of another client in a subsequent matter.
Prof.Cond. R. 1.0(n). In this context, any confidential factual information obtained from
a defendant that could advance the position of the prosecutor’s office in other matters
would serve to disqualify the county prosecutor from personally prosecuting a defendant
without consent.
Clients of the Public Defender’s Office but not Former Clients of the County Prosecuting Attorney
Prof.Cond.R. 1.11(d)(1) also requires the county prosecuting attorney to determine
whether he or she is prohibited from personally prosecuting a defendant whose case was
assigned to another public defender during the prosecutor’s tenure as public defender.
Prof.Cond.R. 1.9(b) indicates that, absent informed written consent, a lawyer who was
previously associated with a firm cannot represent another client in the same or
substantially related matter when the clients’ interests are materially adverse and when
the lawyer previously acquired information about the former firm’s client that is
protected by Prof.Cond.R. 1.6 or 1.9(c).1 In relation to the clients of a lawyer’s former
firm, the comments to Prof.Cond.R. 1.9 explain that a lawyer is disqualified only when
he or she acquired actual knowledge of information protected by Rules 1.6 and 1.9(c).
Prof.Cond.R. 1.9, cmt. [5]. If a lawyer acquired no knowledge or information relating to
a specific client of the former firm, neither the lawyer nor the lawyer’s new firm is
1 Prof.Cond.R. 1.0(c) defines a public defender office as a law firm.

prohibited from representing another client in the same or substantially related matter.
Id.
The interests of a county prosecuting attorney and his or her client, the state of
Ohio, are materially adverse to clients of the public defender’s office. Therefore, the
prosecutor must complete an individual assessment in each case that was assigned to the
public defender’s office during his or her tenure as public defender to determine whether
he or she obtained protected client information. A lawyer’s involvement in a matter can
be a question of degree and depends on the particular facts of a situation. Id. at cmt. [2],
[6]. If lawyers in the public defender’s office had access to all client files or the lawyers
regularly discussed client matters, it is reasonable to assume that the county prosecuting
attorney, while serving as the public defender, obtained protected information regarding
clients of the public defender’s office. In that circumstance, the prosecutor is prohibited
from personally prosecuting a defendant whose case was assigned to the public
defender’s office during the prosecutor’s tenure in that office, unless that defendant
provides informed written consent.
If, while employed as the public defender, the county prosecuting attorney had
access to only his or her own or limited client files and did not participate in discussion
of other public defenders’ client matters, then it is reasonable to assume that the
prosecuting attorney did not obtain protected information regarding other clients of the
public defender’s office. In that scenario, the county prosecutor is not prohibited from
prosecuting an individual who was represented by another public defender during the
prosecutor’s tenure as public defender.2
2 This opinion addresses only ongoing cases assigned to the public defender’s office at the time of the
lawyer’s transition from public defender to county prosecutor. It does not address subsequent prosecutions
in unrelated matters of a former client of the county prosecutor or of other individuals who were clients of
the public defender’s office during the county prosecutor’s tenure but not personally represented by the
prosecuting attorney. If a subsequent prosecution of one of the individuals referenced above is necessary,
the county prosecutor must complete another conflict analysis pursuant to Prof.Cond.R. 1.11(d) and 1.9.
The reader is reminded of the general prohibitions contained in Prof.Cond.R. 1.9(c) related to the use of
information obtained from a prior representation to the disadvantage of a former client or a former client
of a former firm.

Op. 2022-04 4
Imputation of Conflicts of the County Prosecuting Attorney to Assistant Prosecuting Attorneys
As the Board has previously indicated, Prof. Cond. R. 1.11 is “intended to be the
exclusive rule governing the imputation of conflicts of interest of current or former
government lawyers.” Adv. Op. 2022-01; ABA Ctr. for Prof’l Responsibility, A Legislative
History: The Development of the ABA Model Rules of Professional Conduct 1982-2013, at 264
(2013). See also Prof.Cond.R. 1.10(f). Because of the special problems associated with the
imputation of conflicts within a governmental entity, the conflicts of the county
prosecuting attorney are not imputed to other associated government officers or lawyers
within the prosecuting attorney’s office. Prof.Cond.R. 1.11, cmt. [2]. Thus, another
assistant prosecuting attorney may handle matters the county prosecuting attorney is
prohibited from handling. Nonetheless, it is generally prudent for the office to screen the
county prosecuting attorney from those matters that he or she is prohibited from
handling due to his or her former employment with the public defender’s office. Id.
Although the county prosecuting attorney may not be required under the rules to assign
every matter handled by the public defender’s office during his or her former
employment to an assistant prosecuting attorney, the Board believes the best practice is
to do so out of an abundance of caution and in the interest of preserving the confidence
of defendants and the public.
