D.C. Circuit Halts District Court's Criminal Contempt Probe Into Executive Branch Detainee Transfers

The underlying dispute centers on the President's invocation of the Alien Enemies Act against members of Tren de Aragua, a Venezuelan criminal gang designated as a foreign terrorist organization. On March 15, 2025, the government placed alleged gang members on planes to El Salvador. The district court subsequently issued a temporary restraining order, but the Supreme Court later vacated that order, ruling that the plaintiffs' habeas claims belonged in a different venue.

Despite this vacatur, the district court proceeded with criminal contempt proceedings, arguing the government willfully disobeyed the now-invalid order by transferring custody to Salvadoran authorities.

The government identified then-Secretary of Homeland Security Kristi Noem as the official responsible for the transfer decision. The district court then expanded its inquest, ordering hearings to extract more information from government counsel about the specific events of March 15.

Circuit Judge Rao, writing for the court, held that the district court's widening investigation constituted an abuse of discretion. The opinion stated that the original order lacked the clarity required to support criminal contempt based on the transfer of custody.

The D.C. Circuit further reasoned that the district court's inquiry improperly probed high-level Executive Branch deliberations regarding national security and diplomacy. The court noted that the government had already provided the name of the responsible official, making further judicial investigation unnecessary and improper.

The opinion emphasized that the district court's actions impaired the Executive Branch's constitutional duties. The writ of mandamus was issued to prevent the district court from assuming an antagonistic jurisdiction that encroaches on the autonomy of the Executive Branch.

The case originated from a petition for writ of mandamus in No. 25-5452, arising from the underlying litigation in No. 1:25-cv-00766. The decision was issued on April 14, 2026, with Concurring and Dissenting opinions also filed.
