A town justice in New Paltz, New York, who has also maintained a practice as a divorce attorney, has retired after the state Commission on Judicial Conduct accused him of signing an arrest warrant for a man, when he had also been retained as an attorney for the man’s wife.

Jonathan D. Katz, a two-decade veteran of the bench, said in a phone interview Monday that the incident was an accident, but that it was time for him to retire.
