Prohibits State's law enforcement from participating in immigration enforcement unless action is premised upon valid judicial warrant.

This New Jersey bill prohibits state law enforcement officers from participating in civil immigration enforcement operations unless a valid judicial warrant is issued. The legislation defines a judicial warrant as one based on probable cause and issued by a federal or state judge, while a law enforcement officer is anyone with the power to arrest or convict offenders. To ensure compliance, the Attorney General must create guidelines that direct how these restrictions are implemented. The law takes effect immediately upon passage.
