Marbury v. Madison
John Marshall ruled on this case as the Chief Justice. He first answered that Marbury had a right to his job because it had been signed and approved. The actual delivery was a custom, not a requirement. He then ruled that a writ of mandamus (a type of court order) was the correct way for Marbury to rule. Finally, he noted that the Judiciary Act of 1789 allowed the Supreme Court to make this kind of ruling.
