This quickly becomes a standard ritual at the changing of each administration, and an accepted job hazard for incoming justices.
E.g. from the court's opinion:
> Whenever the President and Vice President discuss their official re- sponsibilities, they engage in official conduct.
It's not a huge leap to infer that the President, as Commander in Chief, is engaging in official conduct any time they ask the army (or its many contractors) to do something.
The only thing the Constitution says is:
> The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States
There's nothing in there that says they can't be used domestically, or for what purposes the President can control them. There could be some quibbling about what "actual Service" means, but I suspect it becomes recursive to "whatever the president says actual Service is".
The specific reason that everyone is freaking out is this part of the opinion:
> In dividing official from unofficial conduct, courts may not inquire into the President’s motives. Such a “highly intrusive” inquiry would risk exposing even the most obvious instances of official conduct to ju- dicial examination on the mere allegation of improper purpose.
I.e. the president's motive is unquestionable, the only question is whether the action was taken via some power granted to the President. If it is, the President has immunity, and the president has _very_ broad powers.
This is a misleading partial quotation. In the context of what they were saying, the president has the presumption of immunity, but it is not guaranteed. They specifically remanded the issue of Trump trying to get Pence to break the law to the lower courts to decide whether there was immunity. They did not say there was blanket immunity.
The question then becomes whether that presumption of immunity is rebutted under the circumstances. It is the Government’s burden to rebut the presumption of immunity. The Court therefore remands to the District Court to assess in the first instance whether a prosecution involving Trump’s alleged attempts to influence the Vice President’s oversight of the certification proceeding would pose any dangers of in- trusion on the authority and functions of the Executive Branch.
"Distinguishing the President’s official actions from his unofficial ones can be difficult."
-SCOTUS
If you can't enter private comms into evidence, all a president need do is privately communicate the disappearance of someone, domestic or foreign, and that evidence would be barred from any possible court cases.
Of course, you could still impeach, but no criminal prosecution could occur. If you're 35, at worst (legally) you'd lose out on your remaining term.
The implications of this ruling are absurd, and rife for abuse, should one decide to go rouge.
Good on you!
I’m not saying it should be done, but that’s the reductio ad absurdium this decision leaves us with. The aspiring despot’s toolbox has been converted into a full-blown machine shop.
