In New York, can a part-time assistant county attorney also serve as mayor of a city in that county?

Plain-English summary

The Columbia County Attorney asked whether a part-time assistant county attorney could also serve as the part-time elected mayor of a city in the county. The AG said yes, under the specific facts.

The Columbia County Attorney's office handles: prosecuting Persons in Need of Supervision (PINS) and juvenile delinquents under the Family Court Act; appearing in support proceedings under that Act; representing the county in civil matters; conducting real property tax foreclosures; and providing legal advice to the Board of Supervisors and county officials. The proposed assistant county attorney would not work on any legal matters affecting his city. His responsibilities would be limited to Family Court Act work.

The compatibility analysis runs through the People ex rel. Ryan v Green framework. No statutory bar applies. County Law § 411, which restricts certain dual-office holding by elected county officers, does not address the assistant-county-attorney / city-mayor combination. The two positions are in separate governmental units (the county and the city), so there is no subordination of one to the other.

The duties also do not inherently conflict. PINS and juvenile delinquency prosecution under the Family Court Act runs through Family Court, not through city government. Family-Court support proceedings affect individual family-court litigants, not city policy. Limiting the assistant county attorney's role to Family Court Act matters keeps him out of the civil county-county-matters that might cross with city government on permitting, contracts, or shared services.

The AG also flagged a useful sub-point: the county attorney advised that only the deputy county attorney, not the assistant, has authority to perform the county attorney's duties in her absence. So the assistant cannot fill in for the county attorney on matters that might touch the city.

Recusal handles any specific conflicts that arise. If a Family Court Act matter involved a city party in a way that created a conflict, the assistant would recuse from that particular matter.

The opinion adds a recommendation: consult county and city codes of ethics. Local codes may add disclosure or other requirements beyond what State law imposes. The AG cited a string of prior opinions (Op Atty Gen (Inf) Nos. 97-46, 95-33, 91-62, 87-16, 86-63) reaching similar conclusions on county-officer service to local governments within the county.

This opinion was issued in 2000. Subsequent statutory amendments, court decisions, or later AG opinions may have changed the analysis. Treat this page as historical context, not current legal advice. Verify current law before relying on any specific rule, deadline, or remedy mentioned here.

Common questions

What changes if the assistant county attorney's portfolio expands?

The compatibility analysis depends heavily on the limited Family Court Act scope. If the role were broadened to include civil matters that could affect the city (tax disputes, joint contracts, intergovernmental disputes), the compatibility could collapse. The AG opinion's "under the circumstances presented" caveat is doing real work.

What if there is no city attorney and the mayor's office handles legal matters?

That would create direct conflict potential. The mayor in his city role would need outside counsel for any matter where the county was involved. The structural firewall between the two roles depends on the city having its own attorney for matters that might touch the county.

Does this apply to a town supervisor or village mayor too?

The structural analysis is similar: separate governmental units, no subordination, limited overlap. The specific statutory bars need to be checked (County Law § 411 is one; other statutes may apply differently to town supervisors or village mayors).

What if the mayor is also a member of the county Board of Supervisors?

County Law § 411 reaches "elective county officer" combinations and may apply. The town supervisor / county supervisor combination is the most common pattern (since town supervisors sit on the county board in most New York counties); the AG has addressed those scenarios separately.

What if the assistant county attorney runs for mayor while still employed by the county?

The candidacy itself is governed by the Election Law and any county personnel rules; the dual-employment opinion does not address candidacy questions. Once elected, the compatibility analysis from this 2000 opinion applies.

Background and statutory framework

County Law § 411 imposes dual-office restrictions on certain elected county officers (judges, district attorneys, sheriffs, county clerks). The provision does not extend to non-elected county positions like assistant county attorney.

The compatibility doctrine from People ex rel. Ryan v Green is the framework for cases where the Legislature has not spoken. The AG has produced a long string of opinions applying the doctrine to county-officer / local-government combinations. Most follow the pattern of this 2000 opinion: separate units, no subordination, recusal for specific conflicts, consultation with local codes of ethics recommended.

The mayor / assistant county attorney combination is unusual but not problematic in the specific configuration Columbia County described. The narrow Family Court Act portfolio is the key fact that prevents subordination or duty conflict from creeping in.

Opn. No. 2000-9
COUNTY LAW § 411.
Under the circumstances presented, an assistant county attorney may also serve as mayor of a city
located within the county.

Informal Opinion
No. 2000-9

Dear Ms. O'Connor:
You have inquired whether a part-time assistant county attorney may also serve as the part-time
elected mayor of a city located within the county. This opinion will confirm our prior discussions
regarding this matter.
You informed us that the county attorney's office prosecutes persons in need of supervision and
juvenile delinquents under the Family Court Act; appears in support proceedings under that Act;
represents the county in civil matters; conducts real property tax foreclosures; and provides legal advice
and assistance to the Board of Supervisors, elected county officials and department heads. You have
stated in your letter that the assistant county attorney would not personally engage in any legal matter
affecting the city of which he is mayor, and would be responsible for only Family Court Act matters.
In the absence of a constitutional or statutory prohibition against dual office holding, one person
may hold two offices simultaneously unless they are incompatible. People ex rel. Ryan v. Green, 58
N.Y. 295 (1874). The Court of Appeals has held that two offices are incompatible if one is subordinate
to the other or if there is an inherent inconsistency between the duties of the two offices. Id. at 304. Even
where positions are compatible, a conflict of interest may arise with respect to particular matters. In
many instances, conflicts can be avoided by declining to participate in the disposition of the matter.
In our view, the positions of assistant county attorney and of mayor of a city located within that
county are compatible. We are not aware of any statutory prohibition against holding these two positions
simultaneously. See, e.g., County Law § 411 (pertaining to "holding more than one elective office").
The positions are in two separate governmental units. Therefore, one is not subordinate to the other.
Nor do the duties of the positions appear inconsistent. You state in your letter that the assistant
county attorney would not engage in any legal matters pertaining to the city, thus removing any potential
for a conflict of duties between the two positions. Significantly, you informed us further that the
assistant county attorney's responsibilities are limited to prosecution of persons in need of supervision
and juvenile delinquents under the Family Court Act and representation of the county in support
proceedings under that Act. These responsibilities should not conflict with the attorney's mayoral duties.
You added that only the deputy county attorney, and not the assistant county attorney, has authority to
perform the duties of county attorney in your absence, thus removing another potential source of
conflict. We believe that if a conflict of interest does arise, recusal in the legal matter ordinarily would
be an appropriate and adequate remedy.
Finally, we recommend that you consult the county and city codes of ethics to determine whether
there are any standards that would bear on the holding of these two positions. We note that in prior
opinions of this office, we have determined that various county officials may serve other local
governments located in the county. See Op Atty Gen (Inf) Nos. 97-46, 95-33, 91-62, 87-16, 86-63.
We conclude that in the circumstances outlined here an assistant county attorney may also serve
as mayor of a city located within the county.
The Attorney General renders formal opinions only to officers and departments of State
government. This perforce is an informal and unofficial expression of the views of this office.
Very truly yours,
JAMES D. COLE
Assistant Solicitor General
