SCOTUS has a role in this too. I know folks are cheering on their decision yesterday BUT: Early on they effectively decided that inconveniencing the powerful (Trump) was worse than we the people being illegally taxed for a year and didn't do anything until later / let the case roll through the system. And now ... he's at it again.
His actions are entirely predictable, he has said he would do it, and it means that it SCOTUS sticks to their game plan that lead us to their last decision ... SCOTUS is not relevant and illegal taxes continue while new cases spin up and the SCOTUS majority folds its arms.
In the meantime as individuals who were illegally taxed, I doubt we see a dime back.
