The American Service-Members' Protection Act (ASPA, Title 2 of Pub.L. 107–206, H.R. 4775, 116 Stat. 820, enacted August 2, 2002) is a United States federal law that aims "to protect United States military personnel and other elected and appointed officials of the United States government against criminal prosecution by an international criminal court to which the United States is not party." Introduced by U.S. Senator Jesse Helms (R-NC) and U.S. Representative Tom DeLay (R-TX) it was an amendment to the 2002 Supplemental Appropriations Act for Further Recovery From and Response to Terrorist Attacks on the United States (H.R. 4775). The bill was signed into law by U.S. President George W. Bush on August 2, 2002.
ASPA authorizes the U.S. president to use "all means necessary and appropriate to bring about the release of any U.S. or allied personnel being detained or imprisoned by, on behalf of, or at the request of the International Criminal Court." This authorization has led the act to be nicknamed the "Hague Invasion Act", because the freeing of U.S. citizens by force might be possible only through an invasion of The Hague, Netherlands, the seat of several international criminal courts and of the Dutch government.
The act prohibits federal, state and local governments and agencies (including courts and law enforcement agencies) from assisting the court. For example, it prohibits the extradition of any person from the U.S. to the Court; it prohibits the transfer of classified national security information and law enforcement information to the court; and it prohibits agents of the court from conducting investigations in the U.S.
The act also prohibits U.S. military aid to countries that are party to the court. However, exceptions are allowed for aid to NATO members, major non-NATO allies, Taiwan, and countries that have entered into "Article 98 agreements", agreeing not to hand over U.S. nationals to the court. The president may waive this prohibition if he determines that to do so is "important to the national interest of the U.S."
