Passage:
For more than a century, international jurisprudence governing state immunity was dominated by the doctrine of absolute sovereign immunity. First articulated in American law by Chief Justice John Marshall in the landmark 1812 ruling The Schooner Exchange v. McFaddon, this doctrine held that a sovereign state was completely immune from the judicial jurisdiction of another nation's domestic courts without its explicit consent. Marshall reasoned that the perfect equality and absolute independence of sovereigns precluded one nation from subjecting another to its domestic judicial authority, regardless of whether the disputed acts involved military operations, diplomatic functions, or commercial enterprise.

By the mid-twentieth century, however, the proliferation of state-owned commercial entities—particularly in socialist and post-colonial nations—rendered the absolute theory economically untenable for private commercial actors. Private enterprises contracting with foreign state-owned corporations frequently found themselves without legal recourse when contractual breaches occurred, as state entities routinely claimed immunity under classical doctrine. In response to these mounting commercial inequities, Jack B. Tate, the Acting Legal Adviser to the United States Department of State, issued an administrative policy directive in 1952 that formally shifted American policy toward the restrictive theory of sovereign immunity. Known as the Tate Letter, this declaration established that foreign states would retain immunity regarding their public sovereign acts (jure imperii), but would forfeit immunity with respect to their private or commercial activities (jure gestionis).

Crucially, the Tate Letter left the determination of whether an activity was sovereign or commercial to the executive branch rather than to the judiciary. Whenever a private litigant initiated a lawsuit against a foreign state, the State Department would issue a 'suggestion of immunity' to the presiding court, effectively binding the judicial outcome. This administrative framework generated severe diplomatic friction and inconsistent legal results, as foreign governments routinely lobbied the State Department to classify clearly commercial disputes as immune sovereign matters to avoid liability.

To eliminate executive discretion and depoliticize jurisdictional determinations, the United States Congress enacted the Foreign Sovereign Immunities Act (FSIA) of 1976. The FSIA transferred the sole authority for determining immunity from the Department of State to the federal courts, codifying statutory exceptions to immunity centered on the 'commercial activity' doctrine. Under the FSIA, courts determine whether an act is commercial by evaluating the objective nature of the conduct rather than its subjective purpose.
