A US appeals court has blocked changes to a controversial New York City police programme that a judge ruled had violated the rights of minorities.
In an unusual move, the Second Circuit also removed Judge Shira Scheindlin from the stop-and-frisk case.
The court said her impartiality was called into question by media interviews she gave during the trial.
The policy, in which police stop and search those they suspect of criminal behaviour, reached its peak in 2011.
In August, Judge Scheindlin ruled the New York Police Department had violated the US constitution in the way it carried out stop and frisk, but not through the policy itself.
