Why is Marbury v. Madison important in the American political system?

The court
case of Marbury v Madison was an important one in the American political
system. This court case gave the Supreme Court the power to determine if laws passed by Congress
were constitutional. This was a huge factor politically, because it served as another check on
the power of Congress. Prior to this decision, there was no way that laws could be declared
unconstitutional. Congress now had to consider if a proposed bill would meet the
constitutionality test, which could potentially alter the wording of bills to ensure, if
Congress passed them, the Supreme Court wouldnt strike them down.

This power
has frustrated both the executive and legislative branches. President Franklin Roosevelt wanted
to add younger judges, whom he felt were more in touch with the daily lives of the American
people after the Supreme Court had struck down some of the New Deal bills that Congress had
passed. Members of Congress also have had concerns that unelected judges were getting involved
in the lawmaking process.
