re: SCOTUS isn’t going to mess with immunity

What should happen is that a limited immunity for executive action is established, and it's sent back to the trial court for determinations on that issue (which would lead to another track back to the USSC).

I haven't listened to the oral arguments to make more of a guess as to what they will do. The Colorado case showed they will violate their maxims and answer questions not asked, due to the election. I'm not sure if they would do there here and what that would lead to.
