The main purpose of this legislation, known as the Sovereign Enforcement Integrity Act of 2025, is to prevent state and local law enforcement agencies in the United States from arresting foreign nationals based solely on requests or warrants issued by the International Criminal Court (ICC). The law aims to clarify the authority of federal government over foreign relations and protect U.S. foreign policy interests. Key provisions of the Act include a clear prohibition against state and local law enforcement officers arresting or detaining foreign nationals based on ICC requests.
