I agree the order to reinsert the feeding tube should be made instantly while he considers the case. I'm not one who thinks she has a federal case, but miracles happen and anyway she should not be suffering unneccessarily during the consideration and appeals of her case.
Courts don't issue "instant" orders. They insist on evidence, they have hearings, require briefings, etc. I'm not surprised it wasn't done instantly, particularly since "instantly" was in the middle of the night.
On the other hand, I'd be surprised if any relief is granted. It seems like it would be very easy for this judge to simply rule that the bill authorizing his jurisdiction is a bill of attainder, and hence, is unconstitutional.
And yet, I'd say that a federal court has jurisdiction to hear a case relating to Terry's due process rights, even before Congress passed the law last night. So maybe we'll get lucky, and the court will use that as a basis for intervening.
