Southern District Judge Shira Scheindlin, who found New York City police liable for unconstitutional stop-and-frisk tactics, presided over other high-profile cases and made groundbreaking decisions on e-discovery, is leaving the bench for private practice.

Scheindlin informed her colleagues in writing Wednesday that she would resign effective April 29. She plans to join a yet-to-be-announced large New York City law firm “assisting in client and pro bono matters, teaching and mentoring associates, and engaging in public speaking and writing.”
