The Marbury vs Madison case, decided in 1803, was a landmark Supreme Court case that established the principle of judicial review in the United States. This case arose when William Marbury petitioned the Supreme Court for a writ of mandamus to compel Secretary of State James Madison to deliver his commission as a justice of the peace. The decision asserted the power of the judiciary to review acts of Congress and determine their constitutionality, solidifying the role of the Supreme Court in the American system of government.
