Decide what? That SCOTUS hasn't heard the case?
That's not a "decision" I made; it's just a fact.
Do you believe SCOTUS heard the case?
Incorrect. Again.
"Though it ruled in Trump’s favor, the court also rejected an argument from the Administration that the National Guard deployment could not be reviewed, however."
A federal appeals court has overturned an earlier ruling that found the President’s mobilization of the troops was “illegal.”

That means it can be decided by another court whether it was legal.
That court would be SCOTUS, and COA doesn't get to decide if an act is constitutional, or not.
