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 and counties from adopting policies that would prevent local officials from cooperating with federal immigration enforcement requests. It makes noncooperation with such requests an ethics violation for state and local employees, with penalties including fines up to $1,000 or imprisonment for up to one year for officials who vote to adopt noncooperation policies. The bill amends existing ethics codes to explicitly require cooperation with federal immigration enforcement requests, stating that officials must comply with "lawful requests from a federal agency regarding immigration and customs enforcement." It also creates a state-level defense for municipal employees who face civil actions related to cooperating with federal immigration authorities.
