The court's action suggests it also will dismiss the second case and step away from the controversy, at least for now. The justices did not act on Trump v. Hawaii, the challenge that it had agreed to review along with Trump v. IRAP last June.
The March 6 decree, opposed by the states of Maryland and Hawaii, was suspended. Though the Court does not explain why it treats these two cases differently, it likely stems from one crucial difference between them. Those questions are likely to return to the court soon, perhaps even this term.

Adversary of the ban, who had convinced the two appeals courts to occlude the executive order, stated that the high court should perpetuate to review the cases.
Trump furnished a novel command about immigrants last month, and the management had conveyed the court that meant there was no basis for the justices to pass judgment on the old one.
Justice Sonia Sotomayor was the only judge to dismiss the case as improvidently granted, saying she would have preserved the appeal's court ruling against the ban rather than vacating it all together. It requested the lower court rulings to be deleted. Technically, section 2 (c) of Executive Order No. 13,780 expired on September 24th, though it was replaced with a new travel ban impacting eight different nations.
