Whatever the SC says, is law of the land. Remember, Marbury v Madison.

That wasn't the holding in MvM.

[Reagan Man]

In Marbury v Madison, the USSC asserted its power to review acts of Congress. The outcome gave the SC power to invalidate whatever it determined as a conflict with the Constitution. Thereby establishing the courts power to declare acts of Congress unconstitutional. The SC under John Marshall emphasized that the Constitution is the supreme law of the land and that the SC is the arbiter and final authority of the Constitution. The result of this ruling set the standard that exists till this day.
