The 1976 Foreign Sovereign Immunities Act generally bars suits against foreign governments, except in cases where state immunity is waived; certain admiralty claims; or the suit involves commercial activity, a tort inside the United States (such as a traffic accident), or expropriation of property in violation of international law. Section 221 of the Antiterrorism and Effective Death Penalty Act of 1996 added an exception for U.S. victims of terrorism, for any government designated by the State Department as state sponsor of terrorism. The National Defense Authorization Act for Fiscal Year 2008 added exceptions for torture, extrajudicial killing, aircraft sabotage, and hostage-taking.[6] In 2016, the Justice Against Sponsors of Terrorism Act removed the requirement that a state sponsor of terrorism be officially listed, so that victim families of the September 11 attacks could sue Saudi Arabia.
