Marbury v. Madison 1803
What the case was about: William Marbury was an intended recipient of an appointment as justice of the peace but it was not delivered before the expiration of Adams’s term as president. He applied directly to the Supreme Court of the United States for a writ of mandamus to compel Jefferson’s Secretary of State, James Madison, to deliver the commissions.

What the Supreme Court Decided: Marbury has a right to the commission, the law grants Marbury a remedy, the Supreme Court has the authority to review acts of Congress and determine whether they are unconstitutional and therefore void, Congress cannot expand the scope of the Supreme Court’s original jurisdiction beyond what is specified in Article III of the Constitution, the Supreme Court does not have original jurisdiction to issue writs of mandamus.

My oppinon: I don't think this was fair at all William Marbury was intended to be justice of the peace but the letter wasn't delivered in time evn though it was written well beforehand. The letter had already been signed and sealed.
