US Supreme Court allows Exxon to sue Cuba over seized property, easing foreign immunity rules.

The US Supreme Court ruled 6-3 that Cuban state-owned companies like CIMEX cannot claim foreign sovereign immunity in lawsuits under the Helms-Burton Act. This decision favors Exxon Mobil, which is suing Cuba for confiscated oil assets seized by Fidel Castro's government in 1959, now valued at over $1 billion. The ruling removes a key legal barrier and sends the case back to lower courts for further proceedings. It marks a significant shift amid heightened US-Cuba tensions and could open the door for more claims against Cuba's government.
