White House must return Jordin Melgar-Salmeron, who was deported less than 30 minutes after his removal was barred

An appeals court has ordered the Trump administration to return a man wrongfully deported to El Salvador to the US and to explain how it is complying in a ruling apparently designed to break a pattern of apparent government defiance of judicial orders.

The US court of appeals for the second circuit in New York also required the government to provide a declaration of the current whereabouts and custodial status of Jordin Melgar-Salmeron, who was deported on 7 May less than half an hour after the court had expressly barred his removal.
