The ruling is a victory for the Trump administration, which had asked the court to drop the case after Trump signed a proclamation Sept. 24 that replaced the temporary travel ban on six nations with a new, indefinite ban affecting eight countries. That action made the court challenge moot, the justices ruled.
“We express no view on the merits,” the justices said in a one-page order.
The decision effectively wipes the record clean in the U.S. Court of Appeals for the 4th Circuit, one of two federal appeals courts that had struck down major portions of Trump’s travel ban. That case began in Maryland.
