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 wouldn’t 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.
