The U.S. Constitution is the supreme law of the land, and any statute, to be valid, must be in agreement. It is impossible for a law that violates the Constitution to be valid. This is succinctly stated as follows: “All laws which are repugnant to the Constitution are null and void.” Marbury vs. Madison 5 US (2 Cranch) 137, 144, 176, (1803)

Marbury vs. Madison is a legal case in which, on February 24, 1803, the U.S. Supreme Court first declared an act of Congress unconstitutional, thus establishing the doctrine of judicial review. The court’s opinion, written by Chief Justice John Marshall, is considered one of the foundations of U.S. constitutional law.
