A trial was begun Tuesday in Judge Jack Weinstein’s Brooklyn federal court over a civil rights case brought by a man who alleged the New York City Police Department has failed to stop a practice known as “collars for dollars,” in which officers make false arrests near the end of their shifts to pocket extra overtime pay.

The trial would mark the second time in recent years that the department has been taken to task over allegations that it maintains practices that allow for widespread constitutional abuses; in 2013, then-U.S. District Judge Shira Scheindlin of the Southern District of New York found the department liable for constitutional violations arising from officers’ use of stop-and-frisk.
