Elected officials and advocates have a simple message for the police union: Stop with the nonsense.

Last week, officials joined advocacy organizations to call on NYPD unions to stop using what they call “frivolous legal maneuvers” to block the court-ordered reform process to the controversial stop-and-frisk practice and to separate the issue from their current contract negotiations with the city.

Police unions recently filed another appeal with the U.S. Court of Appeals after they were denied intervening status by Judge Analisa Torres in the federal stop-and-frisk lawsuit.

“New Yorkers and communities whose rights have been violated by stop-and-frisk abuses have waited far too long for reform, since the court first decided to uphold their civil rights over a year ago,” said Priscilla Gonzalez, of Communities United for Police Reform, in a statement. “It is unacceptable for the constitutional rights of New Yorkers to be held captive to the political whims of police unions’ contract negotiations with the city. This only further harms the same communities whose government sanctioned abuses against them, and that’s not only unacceptable but deplorable.

“Police unions should do right by both New Yorkers and the officers they represent by supporting the Joint Remedial Process to move forward, rather than continuing a lost Bloomberg-era fight.”

Last August, a federal court found the stop-and-frisk practice to be unconstitutional. Judge Shira Scheindlin, in a 198-page ruling, found that the NYPD’s practices violated New Yorkers’ Fourth Amendment rights to be free from unreasonable searches and seizures and were also in violation of the Equal Protection Clause of the 14th Amendment because of racial discrimination. Under the Michael Bloomberg administration, Blacks and Latinos made up 90 percent of stop-and-frisk recipients. Under Bill de Blasio, the city officially dropped the case.

“The unions’ attempt to intervene seeks to delay reforms that will improve police-community relations, benefiting all New Yorkers—including NYPD officers,” said Center for Constitutional Rights Senior Staff Attorney Darius Charney in a statement. “For too long, communities of color have felt under siege by the police from illegal, racially-discriminatory policing. We urge the Court of Appeals to reject the unions’ effort to obstruct reforms so that we can begin the collaborative process ordered by the court to create a city in which the rights of all New Yorkers are protected.”

Amicus briefs opposing the police unions’ efforts to intervene and impede the process were filed by Communities United for Police Reform with more than 50 organizational signatories, including New York City Public Advocate Letitia James, elected officials including the New York City Council’s Progressive Caucus, law enforcement associations and legal experts.

“With the support of elected leaders and civil rights advocates, this administration ended the city’s opposition to the stop-and-frisk litigation,” said James in a statement. “As we continue to heal the relationship between minority communities and the NYPD, I join the many voices calling on police unions to end their opposition to these needed, court-ordered policing reforms. It is imperative as we move forward that the police unions demonstrate unity with all New Yorkers as we continue to improve the safety of city residents.”
