What was significant about the court case Marbury v. Madison?

In Marbury v. Madison (1803) the Supreme Court announced for the first time the principle that a court may declare an act of Congress void if it is inconsistent with the Constitution.

Madison the Supreme Court has been the final arbiter of the constitutionality of congressional legislation.
