On May 18, 2020, the United States Supreme Court denied a request by the Bolivarian Republic of Venezuela and its state-owned oil company, Petróleos de Venezuela, S.A. (PDVSA), to review the merits of Crystallex Int'l Corp. v. Bolivarian Republic of Venezuela, a decision by the U.S. Court of Appeals for the Third Circuit. In Crystallex, the Third Circuit affirmed a trial court's determination that PDVSA is the “alter ego” of Venezuela itself, thus permitting Crystallex to enforce a $1.4 billion judgment against Venezuela by attaching property held in PDVSA's name. Given the Supreme Court's decision to leave the Third Circuit's opinion undisturbed, Crystallex is a significant decision that may affect parties involved in transnational litigation for years to come—especially those pursuing or defending against U.S. enforcement proceedings involving the property of foreign states.
