Marbury v. Madison, 5 U.S. (1 Cranch) 137 (1803) is a landmark case in United States law and in the history of law worldwide. It formed the basis for the exercise of judicial review in the United States under Article III of the Constitution. It was also the first time in Western history a court invalidated a law by declaring it "unconstitutional".[1][2] The landmark decision helped define the boundary between the constitutionally separate executive and judicial branches of the American form of government.
A law school funky who actually taught law, yes? Amazing.
