Recent Court of Appeals matters include:

(PDVSA), is the alter ego of the Republic of Venezuela, thus permitting Crystallex to attach PDVSA’s U.S. assets – and in particular the shares of the Delaware parent of CITGO Petroleum--to satisfy Venezuela’s debt to Crystallex. Reporting on the 2019 four-hour oral argument in Venezuela’s first of many attempted appeals, The Financial Times noted that among the lawyers for “Venezuela, PDVSA and a motley of creditors”, Miguel “was the best litigator in the room.” A judicial auction of those assets is expected in the summer of 2024.
