The Sovereign Enforcement Integrity Act of 2025 aims to prevent State and local law enforcement officers from acting on requests, warrants, or indictments issued by the International Criminal Court (ICC). This prohibition extends to arresting, detaining, or otherwise depriving foreign nationals of liberty based solely on ICC process. It also forbids State and local entities from cooperating with the ICC or using their resources to assist in such actions, reflecting the United States' non-party status to the Rome Statute. The bill establishes that these prohibitions can be overridden only under specific circumstances: if Congress enacts legislation expressly authorizing cooperation in a particular case, or if the President certifies cooperation as essential to a declared national security interest and issues a specific written authorization. Furthermore, the Act includes a preemption clause, ensuring that any State or local law, policy, or regulation inconsistent with its provisions is superseded, thereby maintaining uniform national standards for international law enforcement obligations.
