Answer:
Step-by-step explanation:
Marbury v Madison was a landmark case heard by the Supreme Court of the United States in 1803. The case was brought by William Marbury, who was appointed as a justice of the peace by outgoing President John Adams but whose commission was not delivered by incoming President Thomas Jefferson's Secretary of State, James Madison.
Marbury sued Madison in the Supreme Court, seeking a writ of mandamus, which would have compelled Madison to deliver the commission. The case was significant because it established the principle of judicial review, which gave the Supreme Court the power to declare laws unconstitutional.
Chief Justice John Marshall ruled in favor of Madison, denying Marbury's request for a writ of mandamus. However, in doing so, he also established the principle of judicial review, stating that the Constitution gives the Supreme Court the power to declare acts of Congress unconstitutional.
This ruling marked the first time the Supreme Court had ever declared an act of Congress unconstitutional, and it established the principle of judicial review as a cornerstone of the American system of government. The case remains one of the most important decisions in the history of the Supreme Court and the United States.
