Authorizes creation of local civilian review boards to review police operations and conduct; appropriates $600,000.

New Jersey Assembly Bill 5371 authorizes municipalities and counties to establish civilian review boards that investigate police operations and officer conduct in response to specific complaints regarding excessive force, abuse of authority, discourtesy, or offensive language. These boards, composed of at least seven local residents with relevant professional experience, are granted the power to subpoena witnesses and evidence, though their investigations must cease if a related criminal prosecution is initiated. The bill requires board members to complete training developed by the Attorney General within six months of appointment before they can recommend disciplinary actions, and it mandates that law enforcement agencies disclose internal affairs reports and recordings to these boards. Additionally, the legislation appropriates $600,000 from the state General Fund to support the development and delivery of the required training courses for board members.
