This bill seeks to prohibit the International Criminal Court (ICC) from utilizing United Nations facilities located within the United States. It highlights that the U.S. Senate has not ratified the Rome Statute , asserting that the ICC therefore lacks jurisdiction within the U.S. or over U.S. persons, despite maintaining an office at the U.N. headquarters in New York. To achieve this, the legislation directs the U.S. Ambassador to the United Nations to initiate negotiations for a supplemental agreement to the existing United Nations Headquarters Agreement . These negotiations must commence within 30 days of the 80th session of the U.N. General Assembly opening. The goal is to secure an agreement that explicitly prevents the U.N. from hosting, leasing, or otherwise permitting the ICC to use its facilities within the United States.
