- What it's about
Exxon Mobil sued Cuban state-owned entities under the Helms-Burton Act over property confiscated by Cuba decades ago. The Court ruled 6-3 for Exxon, holding that the Act itself removes foreign sovereign immunity for Cuban government agencies and instrumentalities, so plaintiffs do not also have to meet an exception in the Foreign Sovereign Immunities Act.
Question presented
Does the Helms-Burton Act abrogate foreign sovereign immunity in cases against Cuban instrumentalities, even if the parties do not satisfy an exception under the Foreign Sovereign Immunities Act?

Decision
What the Court decided
Exxon sued Cuban government-owned companies over property Cuba confiscated in 1960. The Court ruled that the Helms-Burton Act removes foreign sovereign immunity (protection from lawsuits) for those entities. Plaintiffs need not meet a separate FSIA (a federal law on foreign immunity) exception.
Impact
American nationals whose Cuban property was confiscated can sue Cuban government companies under the Helms-Burton Act. They need not separately meet an FSIA exception (a statutory limit on foreign-government lawsuits). For example, Exxon may pursue its damages claim against companies operating expropriated Esso assets. The ruling lets similar claims proceed against Cuban agencies and instrumentalities without satisfying FSIA exceptions. It may affect other U.S. nationals seeking compensation for confiscated Cuban property.
