Mayor Michael Bloomberg is suing to try to block a law that would make it easier to sue the New York Police Department over stop-and-frisks or other actions people claimed were discriminatory.
The mayor followed through Tuesday on his pledge to go to court over the measure. He sued the City Council, which passed it last month over his veto.
The suit says the legislation treads into an area governed by state law.
Council Speaker Christine Quinn says she’s confident the measure will prevail in court.
The legislation is part of a pair of laws imposing new checks on the NYPD amid complaints about stop-and-frisk and other tactics. The other creates a police inspector general.
Bloomberg vetoed both. His suit concerns only the police-lawsuit measure.
