The New Haven police union decided Wednesday evening not to hold a department-wide vote of “no confidence” on the leadership of Chief Frank Limon, who took up the post in April.

The decision follows a week of public complaints by Union President Louis Cavaliere that Limon’s policies — locking officers out of meetings if they came late and requiring detectives to wear neck ties — were hurting morale.

In an interview Monday, Limon said he is not backing down from his policies.

“It’s a question of principle, of being professional,” he said.

The union made its decision Wednesday night at the Marchegian Club on Cedar Street. Had the union voted to hold a no confidence vote, it would only have been a public display of disapproval by the union and would have had no binding consequences on the chief.

Four aldermen told the News that the union’s wavering faith in the chief is no reason to abandon his efforts to improve public safety in the city.

“I think it’s too soon to count him out,” Ward 6 Alderwoman Dolores Colón said.

Limon arrived in New Haven in April from Illinois, where he served for 30 years in the Chicago Police Department and for about 18 months as police chief in the suburban town of River Forest.

The NHPD last held a vote of “no confidence” in 2005 against then-Chief Francisco Ortiz, now head of guard operations for Yale Security.
