Okay so in that case what Biden could do is go ahead and execute all of his political opponents and then if the lower court returns that the ruling of the supreme Court is unconstitutional than the new supreme Court can decide whether or not to uphold that.
To decide if the list of trumps illegal actions are considered official like social media posts. Now that the rule is set to protect anything official Biden only has to put it on white house stationary to make any action legal.
