What irritates me is the calm acceptance of everyone that “this emergency decree can be adjudicated in court.”
Well, maybe so, but what is NOT in the Constitution is that a lower level Federal judge can veto a Congressionally authorized Presidential executive order.
You are right and I don't think that the Courts aren't going to touch this. This is way outside their lane. Certainly, some numbnuts district court judge may try to do it, but the Circuit Courts and the SCOTUS will quickly put a stop to it. Quickly being the operative word.
