Summary

MEMORANDUM OPINION

In September 2025, the court entered judgment in favor of Petitioners Infrastructure Services Luxembourg S.A.R.L. and Energia Termosolar B.V., confirming an arbitral award of more than $156 million, plus post-judgment interest, against Respondent, the Kingdom of Spain. Spain appealed the judgment to the U.S. Court of Appeals for the D.C. Circuit in October 2025. Pending before the court are the parties' post-judgment motions. Petitioners seek an order pursuant to 28 U.S.C. § 1610(c) permitting them to attach and execute on Spain's assets and an order pursuant to 28 U.S.C. § 1963 permitting them to register the court's judgment in other judicial districts. Spain has filed a cross-motion to stay enforcement of the court's judgment without being required to post a supersedeas bond, or, in the alternative, to quash two subpoenas issued by Petitioners to the Clearing House Payments Company ("Clearing House") and the Federal Reserve Bank of New York. For the reasons explained below, the court will grant Petitioners' motion and deny Spain's cross-motion.
