The U.S. Supreme Court’s conservative majority delivered a major victory to the Trump administration on Monday, allowing immigration officials to resume deporting migrants to third countries without the additional due process safeguards previously mandated by a federal judge.

The high court, offering no detailed explanation, lifted a lower court injunction that had required officials to give migrants advanced notice of their deportation destinations, time to raise fears of torture, and an opportunity to challenge adverse findings before removal. The litigation, which began with a lawsuit filed by detainees allegedly bound for South Sudan, is still ongoing and may take years to resolve.

U.S. District Judge Brian Murphy had issued a preliminary injunction last month, halting the deportation of migrants without sufficient procedural protections. His ruling called for at least 10 days’ notice before removal, and a 15-day window to appeal any government findings. The Supreme Court’s decision effectively restores the Trump administration’s expedited removal policies in the interim.

The administration has already deported migrants to nations including El Salvador, Guatemala, South Sudan, and Libya under this program.

Justice Sonia Sotomayor, joined by Justices Elena Kagan and Ketanji Brown Jackson, issued a scathing dissent, accusing the majority of endorsing unlawful executive overreach in “matters of life and death.”

“This Court now intervenes to grant the Government emergency relief from an order it has repeatedly defied,” Sotomayor wrote. “By rewarding lawlessness, the Court once again undermines the foundational principle that ours is a government of laws.”

She denounced the majority’s decision as an “incomprehensible” use of discretion, arguing it dismisses the real threat of harm to migrants in exchange for relieving the government of what it deemed “onerous” legal obligations.

Immigrant rights groups had urged the court to preserve the injunction, arguing it provided essential due process protections for those being forcibly removed to nations that are not their own. The Trump administration, however, labeled the lower court’s requirements both burdensome and unlawful.

With the Supreme Court’s order, expedited removals to third countries can now resume while the broader constitutional challenge plays out in court.
