New Jersey’s Office of the Public Defender has sued state officials over what it describes as crowded conditions and violent behavior by residents at the Greystone Park Psychiatric Hospital.

Filed on Monday in U.S. District Court for the District of New Jersey, the suit was brought on behalf of a class of current and former residents at Greystone Park by the Division of Mental Health Advocacy, which falls under Public Defender Joseph E. Krakora’s purview.
