Saudi Arabia v. Nelson, 507 U.S. 349 (1993) (U.S. Supreme Court)
Saudi Arabia v. Nelson is a foundational U.S.
Whether the FSIA's commercial-activity exception, or the noncommercial tort exception, permits a U.S. court to exercise jurisdiction over Saudi Arabia and its hospital for claims arising from the plaintiff's arrest, imprisonment, and torture in Saudi Arabia, where the employment was recruited and contracted in the United States.
Under the FSIA, foreign states are presumptively immune from suit in U.S. courts (28 U.S.C. § 1604) unless a statutory exception applies. The commercial-activity exception withdraws immunity in any case "in which the action is based upon" a foreign state's commercial activity carried on in the United States, an act performed in the United States in connection with commercial activity elsewhere, or an act outside the United States in connection with commercial activity elsewhere that causes a direct effect in the United States (28 U.S.C. § 1605(a)(2)). "Commercial activity" is determined by the nature of the act, not its purpose and refers to conduct a private party can engage in (28 U.S.C. § 1603(d)); the key phrase "based upon" looks to those elements of the plaintiff's claim that, if proven, would entitle the plaintiff to relief—the gravamen of the suit. The noncommercial tort exception, 28 U.S.C. § 1605(a)(5), permits suits for certain torts causing personal injury or death "occurring in the United States," subject to enumerated exclusions; it does not reach torts occurring in a foreign country.
No. The action is not "based upon" commercial activity within the meaning of § 1605(a)(2), but upon sovereign acts—arrest, imprisonment, and related police conduct. The noncommercial tort exception, § 1605(a)(5), does not apply because the alleged torts occurred in Saudi Arabia. Saudi Arabia and its instrumentality are therefore immune, and the case must be dismissed for lack of subject-matter jurisdiction.
Nelson is the Supreme Court's leading articulation of how to identify the gravamen of a FSIA claim. It narrows the commercial-activity exception by preventing plaintiffs from bootstrapping sovereign misconduct abroad to antecedent or collateral commercial dealings in the United States. The decision draws a firm line between commercial conduct a private party could undertake (recruitment, contracting, employment) and sovereign acts (police powers such as arrest and detention). For law students, Nelson is essential for FSIA exam questions and practice because it provides the analytical approach later reaffirmed in cases like OBB Personenverkehr AG v. Sachs. It also signals the practical difficulty of obtaining U.S. forum jurisdiction over human-rights-related injuries inflicted by foreign sovereigns abroad, underscoring the importance of careful pleading and the limits of U.S. courts' reach.
