So now the process is to wait years to see if something a president does is technically an 'official act' or not. Seems like there should have been a better way to solve this.
Yup, presidents will enjoy the "presumption of immunity" for practically any action, and the only chance at consequence is years and years down the line after jumping through massive courtroom hurdles, in which it will almost certainly need to be in front of the supreme Court again, where the court majority will forgive 'their' president or convinct the 'other' president.
Years of zero consequence. Imagine what an egomaniacal, unethical, vengeful, unempathetic, asshole could do with all of that power.
