The United States Supreme Court on Wednesday, Sept. 30, 2026, permitted the administration of President Donald Trump to resume deporting migrants to third countries without providing them an opportunity to contest potential dangers. The 6-3 emergency ruling stays a lower court order and strengthens a central mechanism of the administration’s mass deportation agenda.
Supreme Court Lifts Block on Third-Country Removals
District Judge Brian Murphy in Boston. Murphy had previously ruled that the Department of Homeland Security policy to transfer migrants to alternate nations was unlawful. The conservative-majority Supreme Court voted 6-3 to allow the rapid removals to proceed while litigation continues, with oral arguments scheduled for December.
Three liberal justices dissented from the decision to let deportations continue immediately. The underlying class-action lawsuit was brought by immigrant rights groups on behalf of individuals facing transfer without notice or a chance to voice safety fears. Activist tallies show more than 25,000 migrants have been sent to 29 different nations under the policy, with the majority routed to Mexico.
Destinations and Legal Arguments in the Dispute
Deportations under the initiative have included politically volatile locations such as South Sudan, which the U.S. State Department advises citizens to avoid due to armed conflict, kidnapping, and violent crime. Other destination countries include Uganda, Equatorial Guinea, Liberia, and the Central African Republic. Department of Homeland Security General Counsel James Percival praised the ruling on social media, calling it a bad day for criminal illegal immigrants and open-border activists.
Conversely, Trina Realmuto, an attorney for the plaintiffs with the National Immigration Litigation Alliance, described the decision as devastating. She stated that the court has permitted the government to send individuals to third countries where they face persecution or torture before receiving notice or an opportunity to present a fear claim. In February, Judge Murphy ruled that the policy violated immigration procedures and Fifth Amendment due process protections, which typically require notice and a hearing.
Appellate History Leading to the High Court
Prior to the Supreme Court’s intervention, a panel of the U.S. Court of Appeals for the First Circuit in Boston issued a ruling on Friday, Sept. 18, 2026, also finding the third-country removal policy unlawful. That three-judge panel affirmed Murphy’s earlier injunction, ruling that the Department of Homeland Security failed to provide adequate due process. The administration subsequently turned to the Supreme Court to overturn the lower appellate blocks, mirroring earlier legal battles that allowed the expedited removal of eight men to South Sudan.
DHS instituted the policy in March 2025 to manage individuals with final removal orders who could not be returned to their home countries due to immigration court protections. Under the framework, the government relies on diplomatic assurances that transferees will not face persecution. However, critics argue the process bypasses statutory safeguards against sending people to nations where they lack ties or face severe risks.
