This brought Marshall to the third question: Whether the Supreme Court had proper jurisdiction over the case, which would determine whether or not the Court had the power to issue the writ Marbury requested. This issue depended entirely on how the Court interpreted the text of the Judiciary Act of 1789. Congress had passed this Act to establish the American federal court system, since the U.S. Constitution itself only mandates a Supreme Court and leaves the rest of the U.S. federal judicial power to reside in "such inferior Courts as the Congress may from time to time ordain and establish." Section 13 of the Judiciary Act deals with the Supreme Court's original and appellate jurisdictions.
