A Venezuelan government-owned oil company has failed to shake a lawsuit that resulted in a $1.4 billion judgment against it over its expropriation of a Canadian company’s gold deposits.

The U.S. Court of Appeals for the Third Circuit on Monday affirmed a Delaware federal judge’s order allowing plaintiff Crystallex International Corp.’s collection efforts to move forward against Venezuela and Petróleos de Venezuela S.A., or PDVSA, a Venezuelan state-owned oil company.
