Case: Exxon Mobil Corporation v. Corporación Cimex, S.A. (Cuba), et al., No. 24-699
Lower Court: District of Columbia
Docketed: 2024-12-31
Status: Granted
Question Presented: Whether the Helms-Burton Act abrogates foreign sovereign immunity in cases against Cuban instrumentalities, or whether parties proceeding under that Act must also satisfy an exception under the Foreign Sovereign Immunities Act.
The Court heard oral argument on February 23, 2026, with Morgan L. Ratner arguing for Exxon Mobil and the Deputy Solicitor General appearing as amicus curiae in support of the petitioner. The government’s participation, secured by a January 26 order granting divided argument, signals that the executive branch views the statutory interpretation question here as having meaningful consequences for U.S. foreign policy and litigation involving Cuban state entities.
The case arises from Exxon’s claim under Title III of the Helms-Burton Act, which creates a private right of action for U.S. nationals whose property was confiscated by the Cuban government. Exxon contends that Cuban instrumentalities like Corporación CIMEX and Unión Cuba-Petróleo are proper defendants and that Helms-Burton itself supplies the necessary waiver of sovereign immunity. The D.C. courts below disagreed, holding that plaintiffs must independently satisfy an exception under the Foreign Sovereign Immunities Act (FSIA), the general framework governing suits against foreign states in U.S. courts.
The legal question turns on whether Congress, in enacting Helms-Burton, implicitly displaced the FSIA’s immunity framework or merely created a cause of action that still operates within it. The thirteen amicus briefs filed—including submissions from foreign sovereign immunity scholars and foreign relations scholars—reflect genuine disagreement among experts. The respondents argue that the FSIA is the exclusive gateway to suit against foreign sovereigns, a position with substantial support in the Court’s prior decisions interpreting that statute. See SCOTUSblog’s case page for additional background.
The outcome will affect not only Exxon’s claims but also the broader class of Helms-Burton Title III plaintiffs who have filed suit since the Trump administration activated that provision in 2019. A ruling that the FSIA remains a separate hurdle would effectively foreclose many such suits, while a ruling for Exxon would open U.S. courts more readily to claims against Cuban state enterprises.
