Plain-English summary
The inquirer represents criminal defendants in town courts and asked whether he could also accept a part-time position prosecuting vehicle and traffic matters in a local justice court in the same county, noting that the court handles only about five to seven traffic tickets a month.
The committee reaffirmed its long-standing position that an attorney with prosecutorial responsibilities as part of part-time local government employment is disqualified from the private practice of criminal law in every court of the state. Drawing on N.Y. State 544 (1982), N.Y. State 657, and N.Y. State 184 (1971), the committee reasoned that a part-time local prosecutor, in prosecuting violations of local law, acts on behalf of the people of the state; appearing as prosecutor one day and defending a privately charged citizen another day creates an impermissible conflict. The number of cases is irrelevant, and the prohibition applies regardless of job title or whether the attorney actually tries any cases, so long as the attorney has the responsibility to prosecute. A defense practice would also require appearing before judicial officials of the same locality the attorney publicly represents, independently failing the conditions set in N.Y. State 544.
Although these earlier opinions were decided under the former Lawyer's Code (DR 5-105 and DR 9-101), the committee held the result is the same under the current rules. Representing the state as prosecutor while representing a criminal defendant, even in a wholly unrelated case, involves "differing interests" as defined in Rule 1.0(f), creating a conflict under Rule 1.7(a)(1).
On waiver, the committee concluded the conflict is non-consentable. Because the roles of prosecutor and criminal defense lawyer are "inherently incompatible" and the prosecutor has special responsibilities to the public, the lawyer cannot provide competent and diligent representation to each affected client as Rule 1.7(b)(1) requires. Client consent therefore cannot cure it.
In practice
The opinion holds that, under Rule 1.7 as it stood at the time, a lawyer who handles criminal defense in town courts may not also serve as a part-time prosecutor of vehicle and traffic offenses for a locality in the same county. The committee treated the conflict as absolute: it does not turn on the volume of cases prosecuted, the attorney's job title, part-time status, or whether the attorney personally tries cases, only on whether the attorney bears prosecutorial responsibility. Because the prosecutor and defense roles are inherently incompatible, the committee held the Rule 1.7 conflict is non-consentable and cannot be cured by client consent.
Common questions
Q: Does it matter that the court only handles a handful of traffic tickets a month?
A: No. The committee held the number of cases is irrelevant, and that it does not even matter whether the part-time prosecutor actually prosecutes any offenses, so long as the attorney has the responsibility to do so.
Q: Can the clients just consent to the dual role?
A: No. The committee held the conflict is non-consentable, because the prosecutor and criminal defense roles are inherently incompatible and the lawyer cannot provide competent and diligent representation to each client as Rule 1.7(b)(1) requires.
Q: Does the attorney's job title or independent-contractor status change the analysis?
A: No. The committee held that neither title nor part-time or independent-contractor status overcomes the absolute prohibition, citing N.Y. State 657 and N.Y. State 234.
Background and rules framework
The opinion interprets New York Rule 1.7(a) and (b) (concurrent conflicts of interest and the conditions for waiver), corresponding to ABA Model Rule 1.7, together with the Rule 1.0(f) definition of "differing interests." The committee carried forward its conflict analysis from opinions decided under the predecessor Lawyer's Code (DR 5-105 and DR 9-101), holding the outcome unchanged under the current rules.
