Exxon Mobil Corporation v. Corporación CIMEX, S.A. (Cuba), Corporación CIMEX, S.A. (Panama), and Unión Cuba-Petróleo
The D.C. Circuit held that the Cuban Liberty and Democratic Solidarity Act does not independently strip foreign sovereigns of immunity, leaving the Foreign Sovereign Immunities Act as the exclusive basis for jurisdiction. The court vacated the district court's ruling and remanded for further fact-finding on whether the defendants' current commercial operations in the United States satisfy the FSIA's commercial-activity exception.
