Civil rights lawyers are seeking an injunction against the New York City Police Department over its surveillance of the Muslim community after the September 11th attacks.
In a new court filing, the lawyers are asking a judge to put a stop to further police surveillance without evidence of crimes.
They also want a new court-appointed auditor to oversee police activities.
The lawyers say NYPD methods violate the Handschu guidelines set in a landmark legal ruling back in 1985.
That ruling set strict time limits for investigations, imposed rules on the kinds of records police could keep and created a three-person body to oversee such investigations.
The NYPD and Mayor Michael Bloomberg say the department follows federal guidelines and has not broken any laws.
