(AP) -- New York City has dropped its federal appeal in cases that challenged its police stop-and-frisk tactic that a judge has said sometimes discriminates against minorities.

The city's decision is aimed at speeding reforms it has already agreed to in a settlement.

The law department filed papers Wednesday with the 2nd U.S. Circuit Court of Appeals.

After a judge last year concluded that the city sometimes discriminates against minorities with its stop-and-frisk program, various police unions tried to intervene to overturn the findings. A lower-court judge last week rejected the request.

A lawyer for the Sergeants Benevolent Association did not immediately respond to a request for comment.
