The Supreme Court ruled foreign sovereign immunity does not shield Cuban state-owned companies from US lawsuits over expropriated property, opening the door for ExxonMobil to seek compensation for assets seized after the 1959 revolution.
The Supreme Court ruled 6-3 Tuesday that Cuban state-owned companies cannot claim foreign sovereign immunity to block ExxonMobil's lawsuit seeking compensation for assets seized after Fidel Castro's revolution. The decision marks the second time in as many months the high court has sided with US owners of Cuban-confiscated property.
"This decision removes a critical legal shield that had protected Cuban state enterprises from US court jurisdiction," said John B. Bellinger III, former legal adviser to the State Department. "It effectively tells US companies with decades-old claims that American courts are now open for business."
The ruling centered on the 1996 Helms-Burton Act, which the justices said overrides the Foreign Sovereign Immunities Act for claims involving property expropriated by Cuba's communist government. The case targets CIMEX, a Cuban state-owned conglomerate that controls assets including the Havana airport — a facility privately owned before Castro's government seized it more than 65 years ago.
The decision could unlock billions of dollars in claims against Cuban state-owned enterprises, potentially straining US-Cuba relations further as the Trump administration already squeezes the island with an oil embargo. The White House has treated the Helms-Burton Act as an additional lever to pressure Havana, and Tuesday's ruling strengthens that hand.
What the ruling means for US claimants
The court's interpretation of the Helms-Burton Act effectively narrows the scope of foreign sovereign immunity for countries designated as state sponsors of terrorism. Cuba has been on that list since 1982. The last time the Supreme Court addressed similar questions of sovereign immunity in a terrorism-related context was in 2023, when it allowed victims of state-sponsored terrorism to seize assets held by foreign governments.
For ExxonMobil, the ruling revives a legal fight that had been stalled by lower courts. The Irving, Texas-based oil giant has not disclosed the value of its expropriated Cuban assets, but analysts estimate claims by US companies against Cuba total in the tens of billions of dollars. Other corporations with pre-revolution holdings in Cuba — including hotel operators, sugar producers and mining companies — could now pursue similar lawsuits.
The decision also carries implications beyond Cuba. Legal experts say the ruling could embolden US companies with claims against other state sponsors of terrorism to test the limits of the Helms-Burton framework in American courts.
Market and diplomatic fallout
The ruling comes as the Trump administration pursues a dual-track strategy of tightening economic pressure on Cuba while negotiating with Iran — another state sponsor of terrorism — over a permanent end to the war that began in February. The administration has already imposed an oil embargo on Cuba and restricted travel, measures that have deepened the island's economic crisis.
Investors holding Cuban sovereign debt or claims on expropriated assets may view the ruling as a positive signal. However, any actual recovery of assets would require navigating complex legal hurdles, including proving ownership chains that stretch back more than six decades and overcoming potential appeals from Cuban defendants.
The Cuban government has not yet responded to the ruling. State-owned enterprises named in future lawsuits could face asset seizures in US jurisdictions if they maintain commercial operations or bank accounts within American borders.
