An upstate judge has resigned amid charges that he pulled strings to get his ex-brother-in-law off the hook for driving drunk, the Commission on Judicial Conduct announced Wednesday.

James Mann, the judge of Nunda Town and Village Courts for nearly 20 years, was brought up on disciplinary charges in October for calling the town police chief and asking that his former brother-in-law — who was in the process of getting arrested — get a “break,” according to an Oct. 10 complaint issued by the commission.

The ex-in-law, James Forrester, had been in the car with Mann’s ex-wife, who called the jurist as Forrester was pulled over by cops around 8:30 p.m. Aug. 16, 2016. Forrester admitted to drinking that night and failed three field sobriety tests, prompting the police to cuff him, the complaint said.

After Mann’s call to the police chief, the head cop told the officers to let Forrester go and have someone else drive his car home, according to the complaint.

Mann — who isn’t a lawyer — resigned effective Dec. 1 and agreed to not work as a judge again.

“Public safety and the integrity of the judiciary are both compromised when a judge thwarts a lawful arrest, especially for something so serious as driving while intoxicated,” said Commission Administrator Robert Tembeckjian. “Exerting special influence to get such a ‘break’ for a friend or a relative is unquestionably and obviously dangerous and wrong.”

Mann’s lawyer did not immediately return a request for comment.
