This week, Clay Jenkinson interviews frequent guest Beau Breslin of Skidmore College about the most famous decision in Supreme Court history. One William Marbury sued the US Government for not installing him into a post to which he had been appointed by outgoing President John Adams. Marshall could not find a way to get Marbury his job, but he did declare that the Supreme Court was the final arbiter of the Constitution, that it emphatically had the duty of determining which laws were constitutional and which were unconstitutional. Beau Breslin helps Clay sort out this monumental decision of 1803, which changed the nature of the US Court System forever.
