The Supreme Court delivered a major win to President Donald Trump on Friday in his ongoing war with the federal judiciary, limiting the power of courts to step in and block policies on a nationwide basis in the short term while judges review their legality.

The court tied the hands of judges at a time when Congress has been cowed and internal executive branch constraints have been steamrolled.

One year ago, the Supreme Court recognized criminal immunity for the sitting president. But when it comes to the systematic expansion of executive power, Friday’s ruling — which severely curtails the power of federal district courts to issue nationwide injunctions — dwarfs the immunity decision.
