A majority of the justices concluded that the Venezuelan migrants had brought their cases in the wrong court but that they were entitled to an opportunity to challenge their removal.

The Supreme Court is allowing the Trump administration to use an 18th century wartime law to deport Venezuelan migrants, but says they must get a court hearing before they are taken from the United States.

The ruling said a judge can't block Trump’s plan nationwide but made it clear that people swept up must have a chance to challenge their seizures before they can be deported.
