"I did not see where they decided the order was unlawful or unconstitutional which courts generally do when invalidating an Executive or legislative action."
You were looking for the wrong thing.  Basically, all the TRO does is temporarily (TEMPORARY Restraining Order) prevent enforcement of the order not invalidating it.  This was an appeal to the grant of a TRO not invalidating anything.  That comes on a trial on the merits.  In this case it'll be during the trial for a permanent injunction not the temporary restraining order.
