The Supreme Court cleared the way on Tuesday for Exxon Mobil to seek compensation from Cuban-owned entities over oil and gas assets the Communist country seized in 1960.

Then known as Standard Oil, Exxon had supplied, refined and distributed fuel throughout the island with more than 100 service stations, when its assets were abruptly confiscated after Fidel Castro rose to power and nationalized private property.

Exxon later sued three government-owned companies that it said had been exploiting its stolen refineries and service stations without compensation ever since.

The case was one of two disputes this term over the extent to which thousands of Americans can get compensation in U.S. courts from entities that hold or profit from property taken by the Cuban government. In May, the justices overwhelmingly sided with a U.S.-owned port business that sued major cruise lines that have used confiscated docks in Havana.

The decision on Tuesday comes as President Trump squeezes the Communist country, blocking oil shipments to the island from Venezuela and Mexico. The administration had backed Exxon’s position in the case, telling the justices that such lawsuits are a critical diplomatic tool for dissuading investment in Cuba.
