Exxon Mobil Corp. can move forward with a U.S. lawsuit seeking $280 million from two Cuban companies as compensation for a refinery and other assets seized from the oil giant after Fidel Castro’s 1959 revolution, a judge in Washington said, Bloomberg News reported. The ruling Wednesday by U.S. District Judge Amit Mehta keeps alive Exxon’s suit against a Cuban government-owned conglomerate, Corporacion Cimex SA, and state-run oil company Union Cuba-Petroleo, known as Cupet. Over the years, the U.S. government has recognized thousands of such claims by companies and individuals over property once owned by Americans. Exxon filed its case in 2019 after the Trump administration said that it would no longer block a provision of a 1996 U.S. law allowing private suits over property seized in Cuba, a policy change some legal experts said would spur a surge in claims. But that hasn’t happened, partly because it may be difficult to enforce financial judgments against companies in foreign countries, said Patrick Borchers, a law professor at Creighton University who has studied the issue. “A lot more cautious potential plaintiffs kind of sat back to see how things are gonna go,” Borchers said. In 2014, President Barack Obama sought to establish diplomatic ties with Cuba and ease economic barriers, though the island nation remains as isolated as ever after failing to make peace with foreign creditors. That’s left more than 5,900 expropriation claims in limbo. Exxon said Cimex and Cupet engaged in “unlawful trafficking in plaintiff’s confiscated property,” including hundreds of service stations, storage tanks, a marine terminal and the Ñico Lopez refinery in Havana. Castro’s government claimed the assets in 1960. Read more.
