A Staten Island judge denied a police union's request to temporarily halt the implementation of the city's vaccine mandate that is set to take effect November 1.

The Police Benevolent Association, New York City's largest police union, had argued in their request for a temporary restraining order on Monday that the policy does not make clear potential exceptions for medical or religious reasons, and does not give unvaccinated officers sufficient time to apply for such exemptions, as those appeals must have been submitted by Wednesday — one week after the mandate was announced, CBS reports.

The PBA, which represents 24,000 officers, said 10,000 of the roughly 35,000 uniformed NYPD officers have not gotten the shot. Last week, Mayor Bill de Blasio eliminated the test-out option and said all city employees must receive their first vaccine dose by Oct. 29 or face unpaid leave, Bloomberg News reports.

"Today's ruling sets the city up for a real crisis. The haphazard rollout of this mandate has created chaos in the NYPD," PBA President Patrick J. Lynch said in a statement. "City Hall has given no reason that a vaccine mandate with a weekly testing option is no longer enough to protect police officers and the public, especially while the number of COVID-19 cases continues to fall."

The union plans on filing an immediate appeal to the ruling. The NYPD could not immediately be reached for comment.
