More than six decades after Cuba’s revolution redrew the island’s economic map, the aftershocks have reached the marbled courtroom of the U.S. Supreme Court.
At the center stands ExxonMobil, arguing that it deserves compensation exceeding $1 billion for oil and gas assets seized by Havana in 1960, in the wake of the revolution that brought Fidel Castro to power. What was once a Cold War-era expropriation dispute has now evolved into a high-stakes legal test of how far U.S. courts can reach into foreign sovereign conduct.
The justices heard arguments in two closely watched cases probing the reach of the 1996 Helms-Burton Act. Title III of that law opened the door for American nationals to sue entities that “traffic” in property confiscated by Cuba’s government after 1959. For years, presidents shelved that provision to avoid diplomatic fallout. In 2019, during his first term, Donald Trump revived it—triggering a wave of lawsuits.
Exxon’s claim traces back to a $70 million loss calculated at the time of the seizure. Decades of accrued interest and potential enhanced damages have inflated that figure dramatically. The company sued Corporación CIMEX, a Cuban state conglomerate, accusing it of profiting from the nationalized assets.
But lower courts ruled that Cuban state entities could invoke foreign sovereign immunity—a doctrine that generally shields foreign governments from being sued in U.S. courts unless Congress clearly says otherwise. Exxon now wants the Supreme Court to strip away that shield for Helms-Burton claims, arguing that Congress intended Title III to have teeth.
Some justices signaled discomfort with rewriting sovereign immunity rules through statutory interpretation alone. The tension in the courtroom was unmistakable: how to honor congressional intent without bulldozing long-standing immunity principles that structure global diplomacy.
The second case before the court carries similar undertones but a different cast. Four major cruise operators—Carnival Corporation, Royal Caribbean Group, Norwegian Cruise Line Holdings and MSC Cruises—face allegations of “trafficking” for docking at Havana facilities originally built by an American firm and later seized. A trial court had ordered them to pay $440 million. An appeals court reversed that ruling, finding the original concession would have expired years before the cruise ships arrived.
Beyond the technicalities lies a larger question: can U.S. courts become arenas for resolving decades-old geopolitical grievances? The answer will not only determine Exxon’s claim, but also shape how aggressively American sanctions laws are enforced against foreign state actors and multinational corporations.
A decision is expected by the end of June—one that could recalibrate the balance between economic accountability and diplomatic restraint in U.S.-Cuba relations.
