A federal appeals court has denied a motion by a Canadian mining company to expedite an appeal of a district court order allowing it to seize shares of Citgo Petroleum’s parent company to enforce a $1.2 billion award against Venezuela.

Judge Luis Felipe Restrepo of the U.S. Court of Appeals for the Third Circuit on Wednesday ruled that oral argument on Petróleos de Venezuela S.A. appeal in the case would proceed normally. Crystallex International Corp.. had claimed that the firm was helping the Venezuelan government avoid the judgment.
