Sovereign Enforcement Integrity Act of 2025

S 2935, the Sovereign Enforcement Integrity Act of 2025, prohibits state and local law enforcement officers from arresting, detaining, or assisting with the enforcement of International Criminal Court (ICC) requests against foreign nationals without federal authorization. It directly affects all state, local, and territorial law enforcement agencies and their personnel. The bill requires explicit federal approval - either through specific congressional legislation or a presidential certification of national security necessity - to override this prohibition. This law aims to prevent conflicts with U.S. foreign policy and constitutional authority over foreign relations, as the U.S. is not a party to the ICC.
