Argentine Republic v. Amerada Hess Shipping Corp.

Argentine forces attacked a neutral Liberian oil tanker in international waters outside any designated war zone during the Falklands conflict, ultimately forcing the ship's owners to scuttle it; the owners sued Argentina in U.S. district court invoking the Alien Tort Statute, admiralty jurisdiction, and customary international law's universal jurisdiction principle, and the court of appeals held the FSIA didn't eliminate these preexisting remedies against foreign states.
