W.M.M. v. Trump: Date Argued: January 22nd, 2026; Docket Number: 25-10534

Case Summary:W.M.M. v. Trump is a habeas class-action challenge brought by Venezuelan detainees held in Texas after President Donald Trump invoked the Alien Enemies Act (AEA) through a March 2025 presidential proclamation to detain and remove alleged members of the Tren de Aragua gang to the CECOT prison in El Salvador. After the Supreme Court ruled in related litigation that challenges to removal under the AEA must be filed in the districts of detention and that detainees must receive sufficient notice and opportunity to seek habeas relief before removal, W.M.M. and others filed in the Northern District of Texas, where emergency relief was initially sought but constrained by the district court’s schedule, prompting an emergency stay application in the Fifth Circuit and an administrative stay from the Supreme Court temporarily blocking removals. On remand, the Fifth Circuit panel later issued a 2–1 decision granting a preliminary injunction against removals under the AEA proclamation, finding the detainees faced irreparable harm and were likely to succeed on their claim that the AEA did not authorize the President’s use of the Act in the absence of an “invasion” or “predatory incursion”, while largely crediting the government’s updated notice against broader due process challenges; the government then sought and obtained en banc rehearing, setting the stage for the appeal identified as W.M.M. v.
