Judges in Texas and New York on Wednesday temporarily barred the U.S. government from deporting Venezuelans jailed in parts of those two states while their lawyers challenge the Trump administration’s use of a rarely invoked law letting presidents imprison noncitizens or expel them from the country in times of war.

The Supreme Court has allowed the Trump administration to use a 1798 wartime law, the Alien Enemies Act, to deport Venezuelan migrants it accuses of being gang members, ending the temporary halt on deportations ordered by a federal district judge.

A Texas judge blocked deportations of anyone held in a south Texas detention facility who may be removed under the wartime law, and a New York judge planned a similar order.
