I see no reason this needs to move through the court system again. It's done. It's been decided.
Sure, we could go through it a second time. We could get the current Supreme Court to once again declare that the powers are co-equal but separate. We could do that a second time.
And then a third.
And then a fourth.
When does it stop? It stops when the President says "We're done here."
Those woefully ignorant of history need an occasional “one across the chops” to understand reality.
I have serious doubts that the Supremes would do that again, in fact I am quite sure they won't. Just my personal feelings about how corrupt the system really is. It will take a tyrant to bring these crooks into submission and then we have to fear the tyrant.
We have seen that play out hundreds of times in Western Movies. A town is so corrupt they hire a gun fighter to clean it up, then they have to plot to remove the gun fighter.
