The ruling halts a lower court order that temporarily allowed migrants to challenge their removal to countries outside their homeland.

The Supreme Court on Thursday cleared the way for the Trump administration to deport to South Sudan a group of migrants that have been held for weeks on a military base in Djibouti. The high court’s unsigned order came days after a majority of justices allowed the administration to deport certain migrants to countries other than their homeland with little notice.

The court’s order followed a broader one last month allowing removals to countries with which migrants have no connections.
