Thomas Jefferson defeated John Adams in the 1800 presidential election. Before Jefferson took office, Adams and Congress passed the Judiciary Act of 1801, which created new courts, added judges, and gave the president more control over appointment of judges. William Marbury had been appointed Justice of the Peace, but his commission was not delivered. Marbury petitioned the Supreme Court to compel the new Secretary of State, James Madison, to deliver the documents. The Court found that Madison's refusal to deliver the commission was illegal, but held that the provision of the Judiciary Act of 1789 enabling Marbury to bring his claim to the Supreme Court was itself unconstitutional, since it purported to extend the Court's original jurisdiction beyond that which Article III, Section 2, established. This case establishes the Supreme Court's power of Judicial Review.
