Marbury v. Madison is important because this was the case in which the Supreme Court of the United States declared that it had the power of judicial review.

The Constitution says that it is the supreme law of the land.  No law may be passed that violates the Constitution.  But who gets to decide which laws violate the Constitution?  The Constitution does not say.  In this case, the Supreme Court decided that they are the ones who get to decide on this issue (this is what “judicial review” means).  So, this case is important because it led to the establishment of one of the most important parts of our political system.

Marbury V. Madison, 1803 was a case that established the principle of Judicial Review. Judicial Review gave the supreme court the authority to declare acts of Congress unconstitutional. It was one of the series of landmark decisions of John Marshall that strengthened the federal government.
