Prohibits municipal ordinance to create sanctuary city; establishes State and local employee ethics violation upon noncompliance with federal immigration enforcement request.

This bill prohibits New Jersey municipalities from passing ordinances that require local officials to refuse cooperation with federal immigration enforcement requests. It directly affects municipal and county governing bodies, making such policies void and imposing penalties (including fines or loss of office) on officials who vote to adopt them. The bill also requires local employees to comply with federal immigration requests and provides state defense for employees acting in good faith during such cooperation. Key provisions include banning "sanctuary city" policies and establishing legal protections for local officials who follow federal immigration enforcement requests.
