What a ridiculous decision. The question before the court wasn't the merits of the rule, but whether it should be enjoined during the ongoing appeal process. Allowing it to take effect *before* higher courts review whether it violates immigrant civil rights is preposterous.
If a lower court has found a federal regulation alarming enough to enjoin it nationwide, the Supreme Court should offer a very compelling reason why the government's interest in enforcing it immediately is *more* important than determining whether it is legal on the merits.
The right-wing justices are essentially implementing the vision of Jeff Sessions and Bill Barr, in which lower courts are stripped of nationwide injunction authority — or at least, they are when someone challenges a Republican policy.
