Under
customary international law, countries are normally immune from legal proceedings in another state. Sovereign immunity is sometimes available to countries in international courts and international arbitration; principally not however if acting more as contracting bodies (e.g. making agreements with regard to extracting oil and selling it) nor in boundaries matters. On 3 February 2012, in the case of
Germany v. Italy: Greece intervening, the
International Court of Justice ruled by a majority of 12 to 3 that all attempts by domestic courts, forums and tribunals attempting to supranationally apply
jus cogens relating to
international humanitarian law are overridden by state immunity. The case affirms case law from earlier decisions. The decision was criticized by some commentators for not embracing a nascent movement to waive immunity in cases of human rights violations. Others pointed out that the decision reflected the consensus of actual international custom and practice. The jurisdiction of the
International Criminal Court extends to current heads of state and government of states that are members of the court. Though cases might include acts that leaders take in their official capacities (such as ordering the country's military to commit genocide), they are prosecuted against individuals rather than the country's government as a whole.
United States The 1812 U.S. Supreme Court decision ''
The Schooner Exchange v. M'Faddon'' interpreted customary international law to bar a ship owner from suing to regain a vessel seized by the government of France, which had docked for repairs in Philadelphia. The 1976
Foreign Sovereign Immunities Act generally bars suits against foreign governments, except in cases where state immunity is waived; in certain
admiralty claims; or in claims involving commercial activity, a tort inside the United States involving death, personal injury, or damage to or loss of property (such as a traffic collision), 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 a
state sponsor of terrorism. The
National Defense Authorization Act for Fiscal Year 2008 added exceptions for
torture,
extrajudicial killing,
aircraft sabotage, and
hostage-taking. 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. ==European Convention on State Immunity==
