BackgroundCore Concept

Background

Sovereign immunity is one of the oldest principles in international law. It rests on the idea of the perfect equality and absolute independence of sovereigns, that no state can be compelled to submit to the jurisdiction of another state's courts. This principle was first articulated in American jurisprudence in The Schooner Exchange v McFadden (1812), where Chief Justice John Marshall held that a friendly sovereign's public vessel was immune from suit as a matter of implied consent between nations. For over a century, US courts applied an absolute theory of immunity, with the State Department deciding case by case whether a foreign government deserved protection.

A shift came with the Tate Letter of 1952, which moved US policy toward a restrictive theory of immunity. Under this approach, immunity applied to a state's sovereign acts but not its commercial ones. However, the State Department still made each determination individually. Congress codified and systematised this in the Foreign Sovereign Immunities Act (FSIA) of 1976, codified at 28 U.S.C. §§ 1602–1611, which transferred the immunity determination from the Executive branch to the courts. Under Section 1604, foreign states are presumptively immune unless a Section 1605 exception applies, such as commercial activity, tortious acts, or state-sponsored terrorism.

A critical gap in the FSIA was resolved by the US Supreme Court in Samantar v Yousuf (2010), which held that the FSIA covers foreign states, not individual officials. An individual official's immunity is therefore governed by common law, informed by the Executive branch's views, a distinction that remains central to the Maduro proceedings.

The Topic Explained

Head-of-state immunity operates at two levels. Personal immunity (ratione personae) protects a sitting head of state from any foreign jurisdiction for the duration of their tenure, regardless of the nature of the act. Functional immunity (ratione materiae) protects former heads of state for acts performed in their official capacity, even after they leave office. The distinction matters enormously: personal immunity is absolute while in office; functional immunity can be pierced for acts that are not genuinely sovereign in character.

The "one voice" doctrine is the governing principle in US courts. It holds that the President has exclusive constitutional authority to recognise foreign governments, and the judiciary must not contradict the Executive's determination of who legitimately leads a foreign state. This doctrine, not the gravity of the underlying conduct, has decided the key American cases. In United States v Noriega (S.D. Fla. 1990), Panama's de facto military ruler was denied head-of-state immunity on narcotics charges because Washington had never recognised his government. …
