IN SHORTThe Supreme Court has allowed ExxonMobil to sue Cuban state-owned companies in U.S. courts over property seized by Fidel Castro's government, reviving claims under the Helms-Burton Act. Separately, the U.S. government imposed new sanctions on five Cuban state companies, including those linked to the military conglomerate GAESA, which Cuba's foreign minister rejected as dishonest. In a third ruling, the Supreme Court rejected an effort to change tax foreclosure sales, affirming that counties can sell properties to recoup unpaid taxes, siding with a Michigan county against a family whose home was sold for less than its market value.
