Document Summary
Judgment of the U.S. Court of Appeals for the District of Columbia Circuit
This summary note is machine-generated. Always consult the original materials.

This document is a Judgment issued by the United States Court of Appeals for the District of Columbia Circuit on July 21, 2026, in the appellate proceedings between Titan Consortium 1, LLC (Appellee) and the Argentine Republic (Appellant).

The procedural posture involves an appeal from a prior judgment rendered by the United States District Court for the District of Columbia (Case No. 1:21-cv-02250). The appellate panel, consisting of Circuit Judges Millett, Wilkins, and Garcia, heard the cause on the record following oral arguments by counsel.

In its operative ruling, the Court of Appeals issued a per curiam order affirming the judgment of the District Court. The Court noted that the affirmance was issued in accordance with the accompanying opinion of the court, which was filed on the same date and authored by Circuit Judge Millett. The document itself serves as the formal dispositive order concluding this phase of the appellate review, leaving the lower court's decision intact.
