First Circuit Rules Trump Third-Country Deportation Policy Unlawful Requires Due Process for Migrants

BLUFDHS will very likely escalate this ruling within 90 days, but the required individualized notice procedures, if sustained, would structurally slow a deportation pipeline that has already moved over 25,000 people.

A three-judge panel of the U.S. Court of Appeals for the First Circuit ruled Friday that DHS must give migrants a "meaningful opportunity" to contest deportation to third countries where they lack ties, largely upholding a February order from U.S. District Judge Brian Murphy that found the policy unlawful 123. Circuit Judge Seth Aframe, writing for the unanimous panel, said the right to contest removal "means little" without prior notice of destination and a chance to raise persecution or torture concerns 23. The panel overturned part of the lower ruling on procedural grounds regarding whether officials must first attempt deportation to countries where migrants have ties 1. DHS General Counsel James Percival said on X that the policy "continues" because the ruling is not yet in effect. The National Immigration Litigation Alliance's Trina Realmuto said the decision confirms deportees cannot be sent to undisclosed countries without due process 2. More than 25,000 migrants have been deported to at least 29 third countries under agreements the administration has struck, according to Third Country Deportation Watch 13.

Analysis
The ruling forces DHS to build individualized notice-and-contest procedures into third-country removals rather than relying on blanket diplomatic assurances, slowing a deportation pipeline that has already moved over 25,000 people. Percival's statement that the policy "continues" pending effect signals DHS will keep operating on the current track while litigation proceeds. The administration will very likely seek further appellate review, whether en banc rehearing or a Supreme Court emergency application, within 90 days, given its pattern of immediately escalating adverse third-country rulings to the high court. High confidence in this timeline reflects DHS's public rejection of the ruling's immediate effect and its established practice of seeking Supreme Court intervention in this same litigation twice before.
