The constitutional question in Marbury v. Madison was whether Congress could expand the Supreme Court’s original jurisdiction beyond the categories fixed in Article III of the Constitution, and, behind that, whether the Court itself had the authority to strike down a federal statute that tried. In 1803, Chief Justice John Marshall answered no to the first and yes to the second. Section 13 of the Judiciary Act of 1789 was void insofar as it conflicted with Article III, and the judiciary held the final word on what the Constitution allows. That second answer, judicial review, has governed every constitutional dispute in the country since.
How the Case Reached the Court
William Marbury had been nominated by outgoing President John Adams as a justice of the peace in the District of Columbia. The Senate confirmed him, Adams signed the commission, and the acting Secretary of State, John Marshall, affixed the official seal. The commission was never delivered. When Thomas Jefferson took office, his administration held it back.1Federal Judicial Center. Marbury v. Madison (1803)
Marbury filed directly in the Supreme Court, asking it to issue a writ of mandamus, a court order compelling Secretary of State James Madison to hand over the commission. His statutory basis was Section 13 of the Judiciary Act of 1789, which authorized the Supreme Court “to issue writs of mandamus, in cases warranted by the principles and usages of law, to any courts appointed, or persons holding office, under the authority of the United States.”2Justia. U.S. Constitution Annotated – Power to Issue Writs: The Act of 1789 By going straight to the Supreme Court instead of a lower court, Marbury was invoking original jurisdiction. That choice put the case on a collision course with Article III.
The Three Questions Marshall Asked
Marshall organized the opinion around three questions. Did Marbury have a right to the commission? If so, did the law provide a remedy? And was a writ of mandamus from the Supreme Court the proper remedy? The first two questions produced answers favorable to Marbury. The third is where the constitutional issue lives.
Marbury’s Right to the Commission
Marshall concluded the right was fully established. The President had signed, the Secretary of State had sealed, and the underlying statute gave Marbury a five-year term independent of the executive. Once those steps were complete, the appointment was no longer revocable. Withholding the commission violated Marbury’s legal rights.3Justia U.S. Supreme Court Center. Marbury v. Madison
Whether the Law Owed Him a Remedy
Marshall then distinguished between political and ministerial acts. Political acts, such as choosing whom to nominate, involve executive discretion and are not reviewable by courts. Ministerial acts are specific duties assigned by law, with no room for personal judgment. Delivering a signed and sealed commission was ministerial. The officer performed it under the authority of law, not presidential preference. The United States, Marshall wrote, is a government of laws, not of men, and when a vested legal right is violated the legal system must furnish a remedy.3Justia U.S. Supreme Court Center. Marbury v. Madison
Whether the Supreme Court Was the Right Court
This is where the constitutional question surfaced. Marshall read Section 13 as granting the Supreme Court original jurisdiction to issue writs of mandamus against federal officers. Article III, however, defines the Court’s original jurisdiction narrowly: cases affecting ambassadors, other public ministers and consuls, and cases in which a state is a party. Everything else reaches the Court only on appeal.4Congress.gov. Article III Section 2 Clause 2 Marbury’s case fit none of those categories. He was a private citizen suing a cabinet secretary. If Section 13 gave the Court jurisdiction anyway, then a federal statute was doing something the Constitution did not authorize.
Why Section 13 Could Not Stand
Marshall framed the conflict starkly. Congress had passed a law purporting to add to the Supreme Court’s original jurisdiction. The Constitution set that jurisdiction in a specific, short list. Both could not be valid. If Congress could rewrite the list by ordinary legislation, there was no reason for the Constitution to have set it out at all.5Constitution Annotated. ArtIII.S1.3 Marbury v. Madison and Judicial Review
Marshall rejected the reading that Article III set only a floor. The categories were exhaustive. A written constitution exists to fix limits that ordinary government action cannot cross, and if the legislature could shift those limits at will, the constitution would be supreme in name only.
The Supremacy Clause in Article VI reinforced the point. It declares that the Constitution and laws made “in Pursuance thereof” are the supreme law of the land.6Constitution Annotated. Article VI – Supreme Law, Clause 2 A statute that contradicts the Constitution is not made in pursuance of it and cannot claim supremacy. Section 13, to the extent it enlarged original jurisdiction beyond Article III, was void.
Who Decides: The Birth of Judicial Review
Identifying the conflict was not enough. Marshall still had to answer who gets to declare a statute unconstitutional. His answer became the most quoted line in American constitutional law: “It is emphatically the province and duty of the judicial department to say what the law is.” When two laws conflict, judges must decide which one governs. When one of them is the Constitution, the Constitution wins.3Justia U.S. Supreme Court Center. Marbury v. Madison
Marshall built the argument from structure and logic rather than any explicit constitutional grant. Nothing in the text says courts can invalidate legislation. But if courts were required to enforce statutes that violated the Constitution, the legislature could do anything: strip jury rights, impose forbidden punishments, or restructure the government by simple majority. Judges would have to close their eyes to the Constitution and read only the statute. That result, Marshall wrote, would subvert the very foundation of written constitutions. He added the judicial oath as reinforcement. Judges swear to uphold the Constitution; requiring them to enforce laws that violate it would force them to break that oath.
Why Marbury Lost
The practical outcome followed from the jurisdictional holding. Because Section 13 could not constitutionally give the Supreme Court original jurisdiction over Marbury’s claim, the Court had no power to issue the writ he wanted. Marbury walked away without his commission.2Justia. U.S. Constitution Annotated – Power to Issue Writs: The Act of 1789
The politics of the result mattered. Jefferson’s administration had refused to deliver the commission and could not comfortably attack a ruling that denied Marbury relief. But the Court, in denying that relief, had established the far more consequential principle that it could strike down acts of Congress. The decision cost the Court a small confrontation and won it an institutional power the Constitution had not clearly given.
What Article III Original Jurisdiction Looks Like Today
The rule Marshall drew from Article III remains the governing rule. Congress cannot enlarge the Supreme Court’s original jurisdiction by statute. Federal law now codifies that jurisdiction consistent with Marshall’s reading: the Court has original and exclusive jurisdiction over controversies between two or more states, and original but non-exclusive jurisdiction over cases involving ambassadors, disputes between the United States and a state, and actions by a state against citizens of another state or against foreign nationals.7Office of the Law Revision Counsel. 28 USC 1251 – Original Jurisdiction
In practice, the Court exercises this jurisdiction rarely. Interstate water rights and boundary disputes account for most of the docket, and the justices typically appoint a special master for fact-finding because the Court has no trial court machinery. Everyone else reaches the Supreme Court by way of appeal, exactly the structure Marshall enforced.
Why the Ruling Still Matters
Judicial review did not remain a theoretical claim. Over more than two centuries, courts have used the authority Marshall asserted to invalidate federal and state laws across the full range of constitutional subjects. Every ruling that strikes down a statute traces its authority to Marbury.
The reasoning still shows up in current decisions. In 2024, the Supreme Court overturned the Chevron doctrine, which had required courts to defer to federal agencies’ interpretations of ambiguous statutes. Writing for the majority in Loper Bright Enterprises v. Raimondo, the Court invoked Marbury directly, stating that legal interpretation “has been, ’emphatically,’ ‘the province and duty of the judicial department’ for at least 221 years.”8Supreme Court of the United States. Loper Bright Enterprises v. Raimondo (2024) A dispute over an undelivered commission in 1803 supplied the language a modern Court used to reset the balance between the judiciary and the administrative state.
