ubiq: A FUNDAMENTAL principle of American constitutional law is that the three branches of the government, the Executive, the Legislative and the Judicial are each COEQUAL to each other. It is an undisputed and basic principle of constitutional law that no court can order Congress to act in any way.
The Vice President of the United States is constitutionally the presiding officer of the United States Senate and of the Joint Session of Congress that is constitutionally tasked with making the final count and determination of the winner of the Electoral College.
As presiding officer, Vice President Michael Pence’s rulings in the Joint Session are final and unappealable.
All of this is basic constitutional law.
