None of that has mattered or will matter to the administration. It’s becoming very obvious that they decide the crime, criminals and punishment (in any order they please). Legal precedent, clear constitutional rights and established jurisdiction don’t mean anything. Whatever rulings they don’t want will be thrown out and the ones they keep will be grist for the fascist mill.

The only thing the judge can do here is release a soundbite that makes it clear the actions that continue are in violation of the court order. Legalese is not that, no matter how technically correct.

Ah so this is another powderpuff order to be ignored. Why not just say “has concrete evidence”? Don’t want to make it too obvious the house of cards has already collapsed when they completely ignore you?

Are there any insights on what the policy implications of new leadership might be? Or is it less a factional takeover and more a “meet the new manager”?

It’s still a fine needle to thread. No matter the reason, loyalty is being sacrificed for competency. Lose too much loyalty and you lose control completely.
