Can a part-time municipal prosecutor who handles traffic cases in the city also defend traffic and criminal cases arising outside city limits?

Plain-English summary

Under Section 16-102 of Chapter 95 1/2 of the Illinois Revised Statutes, a county State's Attorney had authorized certain municipal attorneys to prosecute state traffic charges for violations occurring within their municipalities, with the State's Attorney's written permission. The municipal attorneys also had private practices but did not defend persons charged with traffic violations occurring within their own municipalities. The committee was asked whether it is a conflict of interest for such a part-time municipal attorney, prosecuting traffic charges by the State's Attorney's permission, also to represent defendants charged under the State Traffic and Criminal Codes for violations not occurring within his municipality.

The committee relied on its prior Opinion 823, under which a municipal attorney may accept criminal defense work so long as he refrains from representing defendants for crimes committed within the municipality's territorial limits and the prosecuting judicial official is not a municipal official. The only new wrinkle was that these attorneys now prosecuted under a grant of permission from the State's Attorney, raising the question whether the State's Attorney's office-wide conflict (the duty to prosecute all offenses in the county) transferred to them through Rule 5-105(a) and (d).

The committee concluded it did not. Although prosecuting traffic cases is delegated by the State's Attorney and traffic cases are quasi-criminal, the municipal attorney's duties were restricted to prosecuting violations within the municipality, with no other contact or relationship with the State's Attorney. Distinguishing (per Opinions 789 and 729) between an attorney with general responsibilities, such as a State's Attorney charged with prosecuting all crimes in a jurisdiction, and one appointed to a particular limited field, the committee found this situation fell within the limited-jurisdiction category, so there should be no prohibition on the municipal attorney's privately defending traffic or criminal cases for offenses outside the municipality.

Currency note

This opinion was issued in 1983, under the former Illinois Code of Professional Responsibility and before Illinois adopted the 2010 Rules of Professional Conduct. The ISBA Board of Governors affirmed the opinion in July 2010 as generally consistent with the 2010 Rules (Rules 1.8 and 1.11), while cautioning that the specific standards referenced may differ from the 2010 Rules. Subsequent rule amendments or later opinions may have changed the analysis. Treat this page as historical context, not current guidance.

Common questions

Q: Can a part-time municipal prosecutor take private criminal defense work?

A: The opinion concluded yes, so long as the defense is for offenses outside the municipality's territorial limits; the committee found no conflict where the offenses lie outside his prosecuting authority.

Q: Does the State's Attorney's broad duty to prosecute transfer to the municipal attorney?

A: No. The committee held that because the municipal attorney's authority was limited to violations within the municipality, with no other relationship to the State's Attorney, the office's general conflict did not transfer to him under Rule 5-105.

Q: What was the controlling distinction?

A: Per the opinion, the committee distinguished an attorney with general responsibilities (like a State's Attorney prosecuting all crimes in a jurisdiction) from one appointed to a limited field, and placed this part-time prosecutor in the limited-jurisdiction category.

Background and rules framework

The opinion applied former Illinois Code Rule 5-105(a) and (d) (declining conflicted employment and the firm-wide imputation of that bar), distinguishing prior Opinions 823, 789, and 729. The Board's 2010 affirmation maps the analysis to current Illinois Rules of Professional Conduct 1.8 and 1.11 (special conflict and government-officer rules); the concurrent-conflict analysis the opinion actually applied corresponds to ABA Model Rule 1.7, with the government-lawyer dimension in Model Rule 1.11.
