Marbury v. Madison is the 1803 Supreme Court decision that established judicial review, the power of federal courts to declare laws unconstitutional. Chief Justice John Marshall’s unanimous opinion turned a minor political fight over an undelivered job commission into the foundation of American constitutional law. The ruling denied William Marbury the office he had been promised, but in doing so it claimed for the Supreme Court a power the Constitution had left unspoken: the final say on what the Constitution means.
How the Dispute Began
Thomas Jefferson defeated President John Adams in the 1800 election, ending Federalist control of the executive branch. Before Jefferson took office on March 4, 1801, Adams and the outgoing Federalist Congress moved to entrench their allies in the judiciary. Congress passed the Judiciary Act of 1801, which reorganized the federal courts and created sixteen new circuit court judgeships, all of which Adams filled with Federalists.1U.S. Capitol Visitor Center. Judiciary Act of 1801, April 8, 1800 Separate legislation created justice of the peace positions for the District of Columbia, and Adams spent his final hours in office signing those commissions too. The rushed appointees became known as the “midnight judges.”
William Marbury was one of them. Adams signed his commission and the official seal was affixed, but the paperwork was never delivered. The person responsible for getting the commissions out the door was John Marshall, who was simultaneously serving as Adams’s Secretary of State and had just been confirmed as the new Chief Justice. In the chaos of the final hours, several commissions were left sitting on Marshall’s desk.
When Jefferson took office, he treated the undelivered commissions as invalid and told his new Secretary of State, James Madison, to withhold them. Without the physical document, Marbury could not assume his duties or collect his salary.2Justia. Marbury v. Madison
What Marbury Asked the Court to Do
Rather than start in a lower court, Marbury filed directly with the Supreme Court. He pointed to Section 13 of the Judiciary Act of 1789, which authorized the 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.”3Avalon Project. 1 Stat. 73 – An Act to Establish the Judicial Courts of the United States A writ of mandamus is a court order directing a government official to perform a required duty. Marbury wanted the Court to order Madison to hand over the commission.
Madison never appeared to argue the case, apparently believing the Court had no authority to compel him.
What the Court Decided
Marshall organized his opinion around three questions, and the order mattered. He did not recuse himself, even though he was the official who had failed to deliver the commission in the first place.
First, did Marbury have a right to the commission? Marshall said yes. Once the President signed it and the Secretary of State affixed the seal, the appointment was complete. Withholding the paperwork did not undo the legal act, and Madison’s refusal to deliver it was illegal.2Justia. Marbury v. Madison
Second, did the law provide a remedy? Again, yes. A government of laws must give individuals a way to seek redress when their rights are violated. Delivering the commission was a routine administrative task, not a matter of executive discretion, so the law should offer a way to compel it.
Third, could the Supreme Court itself issue the order? Here Marshall pivoted. Despite ruling for Marbury on the merits, he concluded that the Supreme Court was the wrong court to grant the remedy, and the reason produced the most consequential holding in American constitutional history.
Why the Statute Was Unconstitutional
Section 13 of the Judiciary Act of 1789 appeared to let someone bring a mandamus case directly to the Supreme Court as a first step, part of what lawyers call original jurisdiction. But Article III of the Constitution defines the Court’s original jurisdiction narrowly: cases involving ambassadors, public ministers, and consuls, or cases where a state is a party.4Constitution Annotated. Article III Section 2 Everything else reaches the Supreme Court only on appeal.
Marbury’s dispute, a citizen demanding a commission from a cabinet secretary, fit none of those categories. Marshall concluded that Section 13 had tried to expand the Court’s original jurisdiction beyond what the Constitution allowed, and Congress had no power to do that.5Justia.

Where Judicial Review Comes From
Having found a direct conflict between a federal statute and the Constitution, Marshall asked the question that changed American law: what happens when a law passed by Congress contradicts the Constitution? His answer established judicial review.
The Constitution, Marshall wrote, is “a superior, paramount law, unchangeable by ordinary means.” If Congress could override it through ordinary legislation, the Constitution would be reduced to the level of any other statute, alterable whenever lawmakers chose. That could not have been the framers’ intent. Courts, faced with a conflict between the two, must apply the higher law and treat the inferior one as void. “It is emphatically the province and duty of the judicial department to say what the law is.”6Legal Information Institute. William Marbury v. James Madison, Secretary of State of the United States
With that reasoning, the Court struck down part of the Judiciary Act of 1789. It was the first time in American history the Supreme Court had invalidated an act of Congress.
Why the Ruling Was Politically Shrewd
The Court faced an impossible practical situation. If Marshall had ordered Madison to deliver the commission, Jefferson almost certainly would have ignored the order. The Court had no army, no treasury, and no realistic way to enforce a ruling the executive branch refused to obey. Public defiance by the President would have humiliated the judiciary and set a precedent that executive officials could simply disregard the courts.
Marshall threaded the needle. He used the first two-thirds of the opinion to declare publicly that Jefferson’s administration had acted illegally and that Marbury was entitled to his commission. Then he declined to issue the order, not because the administration was right, but because the statute Marbury had relied on was unconstitutional. Jefferson got his practical victory, and Marbury never received the commission. Marshall got something far more valuable: the established power of the Supreme Court to invalidate acts of Congress. Jefferson was reportedly furious about the rebuke but had no way to challenge a ruling that technically went in his favor.
Why the Case Still Matters
Judicial review was rarely invoked in the decades right after Marbury. The Supreme Court did not strike down another federal statute for more than fifty years.7Federal Judicial Center. Marbury v. Madison (1803) Over time, though, the power Marshall claimed became the defining feature of American constitutional law. Every landmark ruling in which the Supreme Court has struck down a federal or state statute, from school segregation to campaign finance to health care mandates, traces its authority back to Marshall’s opinion.
The case answered a structural question the Constitution had left open: who has the final word on what the Constitution means? Marshall’s answer, the courts, has shaped American government ever since.
