Does the Supreme Court have authority to rule? Sometimes its not a matter of if the decision was correct, but whether the right entity is making it.

In matters of the division of power and authority between the national government and the States, who else would have authority to rule on it?

Why would the Supreme Court have more authority to say when the Legislature/Executive is wrong than the Legislature/Executive has to overrule the Supreme Court? If the Supreme Court is king, then there is no separation of powers. Indeed, what is to prevent a liberal supreme court from making rulings that the Legislature must raise taxes and provide free health care, if they rule that it is a right?

It was a long time after the Constitution's ratification before the Supreme Court decided that it was the final arbiter of constitutionality and Congress/President have failed to rein it in.

Where in the Constitution is such power granted to the Supreme Court? Why would the court make better decisions than the Congress or the President?
