This legislative proposal aims to prohibit state and local law enforcement from arresting or detaining foreign nationals based solely on requests, warrants, or indictments from the International Criminal Court (ICC). It also prevents these agencies from cooperating with the ICC or using public resources for such actions, asserting that the Federal Government holds exclusive authority over foreign relations and the treatment of foreign nationals. The bill emphasizes that the U.S. is not a party to the Rome Statute, and unauthorized state or local enforcement of ICC actions could jeopardize U.S. foreign policy interests and conflict with constitutional principles. Exceptions to this prohibition exist if Congress expressly authorizes cooperation in a specific case, or if the President certifies a national security interest and issues a specific written authorization. This Act would preempt any conflicting state or local laws to ensure federal control.
