Supreme Court lets Exxon pursue Cuba seizure compensation claims

The Supreme Court on Tuesday made it easier for ExxonMobil to press its Cuba seizure claim, ruling 6-3 that the company can keep suing Cuban state-owned entities over assets taken in 1960. Justice Brett Kavanaugh wrote the majority opinion, and Justices Elena Kagan, Sonia Sotomayor and Ketanji Brown Jackson dissented.

The case, Exxon Mobil Corp. v. Corporación CIMEX, S.A. (Cuba), No. 24-699, was argued on February 23 and decided on June 23, 2026. Exxon sued Corporación CIMEX, Unión Cuba-Petróleo, and CIMEX’s Panamanian alter ego for more than $1 billion in damages tied to a refinery, terminals, packaging plants and more than 100 service stations confiscated after Fidel Castro took power. The Court held that the Helms-Burton Act abrogates sovereign immunity for Cuban agencies and instrumentalities in these suits, so plaintiffs do not also have to clear a Foreign Sovereign Immunities Act exception.

That procedural point is the part with teeth. It means Exxon’s case goes back into American courts instead of dying on immunity grounds, and it gives other U.S. claimants with certified Cuba judgments a cleaner path to pursue damages against Cuban state-linked firms accused of trafficking in confiscated property. The decision also leaves more pressure on any company still tied to disputed Cuban assets, because the legal shield around those claims just got thinner.

The scale of the wider claims file is already large. The Foreign Claims Settlement Commission’s Cuba programs recorded 8,821 claims, 5,913 awards and $1,902,202,284.95 in principal awards, and the U.S. has not settled those claims with Cuba. A State Department report filed in May said the department has identified 250 certified claims involving confiscated real property and is mapping those properties to spot possible trafficking by foreign companies.

Exxon’s own claim has grown sharply over time. The Foreign Claims Settlement Commission valued the Cuban property at $71.6 million in 1969, with 6% annual interest starting in 1960. That math has pushed the case to more than $1 billion today, with interest and possible enhanced damages swelling the bill far beyond the original nationalization value.

The Helms-Burton Act, signed by President Clinton in 1996, created a private right of action against anyone trafficking in confiscated property, but presidents repeatedly suspended that right from 1996 until 2019. Donald Trump let that suspension lapse, and Exxon filed suit the same day. The ruling now gives that abandoned claim a second life, turning a 1960 seizure into a live test case for the next wave of Cuba property litigation.
