"In victory for Trump, Supreme Court dismisses travel ban case"

This wasn't a "victory."  Trump in effect cancelled the travel ban with a new, expanded travel ban.  The facts in the new travel ban may or may not continue the issues with the same reasoning as was in the original travel ban.  The new travel ban must be litigated on it's own merits or lack of them.  The Supreme Court was right to close the case and await developments in the lower courts where the new travel ban has already had a new case brought against it.
