The holding in Marbury v. Madison, 5 U.S. 137 (1803), is that federal courts have the power to declare an act of Congress unconstitutional and refuse to enforce it. Chief Justice John Marshall, writing for a unanimous Court on February 24, 1803, found that William Marbury was entitled to his judicial commission and that the law gave him a remedy, but that the Supreme Court itself could not grant it because the statute Marbury relied on, Section 13 of the Judiciary Act of 1789, conflicted with Article III of the Constitution. In striking down that provision, the Court established the doctrine of judicial review.1National Archives. Marbury v Madison (1803)
The Three Questions Marshall Asked
Marshall broke the case into three parts, and the answers form the full holding.
First, did Marbury have a right to the commission? Yes. Marbury had been appointed a justice of the peace for the District of Columbia during the final days of the Adams administration, and the position carried a fixed five-year term. The appointment was complete the moment President Adams signed the commission and the Great Seal was affixed. Physical delivery, Marshall reasoned, is a convenience rather than a legal requirement; the commission is transmitted to someone already appointed, not to someone whose appointment depends on the letter arriving.2Cornell Law School. William Marbury v James Madison, Secretary of State of the United States
Second, did the law give him a remedy? Yes again. Marshall stated the principle that wherever there is a legal right, there must be a legal remedy; a government that can violate rights with no possibility of correction is not a government of laws. Because delivering a signed and sealed commission was a duty the law required rather than a matter of executive judgment, a writ of mandamus was the proper remedy against Secretary of State James Madison.3Justia. Marbury v Madison, 5 US 137 (1803)
Third, could the Supreme Court itself issue that writ? No. And that answer is where the case became a landmark.
Why the Court Refused to Issue the Order
Marbury filed directly in the Supreme Court. He relied on Section 13 of the Judiciary Act of 1789, which stated that the Court “shall have power 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.”4The Avalon Project. The Judiciary Act of 1789
Marshall read Section 13 as an attempt by Congress to give the Supreme Court original jurisdiction over mandamus actions. Article III of the Constitution, however, lists exactly which cases the Supreme Court may hear as a trial court: cases affecting ambassadors and other foreign diplomats, and cases in which a state is a party. Everything else reaches the Court only on appeal.5Congress.gov. Article III Section 2, Constitution Annotated
Marbury was a private citizen suing a cabinet officer. His case did not fit either category. Congress, Marshall held, could not enlarge the Court’s original jurisdiction beyond what Article III specifies, and Section 13 was void to the extent it tried to.6Congress.gov. Constitution Annotated – ArtIII.S2.C2.2 Supreme Court Original Jurisdiction Marbury had a right and a remedy, but he had come to the wrong court.
What Judicial Review Means
Nothing in the Constitution’s text expressly gives courts the authority to invalidate statutes. Marshall built the argument from first principles. A written constitution exists to limit government power. If Congress could pass any law it pleased regardless of those limits, the Constitution would be a suggestion rather than a supreme law. When a statute and the Constitution conflict, some institution must decide which one controls, and because judges take an oath to uphold the Constitution, they cannot enforce a law that violates it.7Congress.gov. ArtIII.S1.3 Marbury v Madison and Judicial Review
Marshall’s most quoted line follows from that reasoning: “It is emphatically the province and duty of the judicial department to say what the law is.” Any law “repugnant to the Constitution” is void and does not bind the courts.2Cornell Law School. William Marbury v James Madison, Secretary of State of the United States With that, the Court positioned itself as the final interpreter of the Constitution.
Ministerial Versus Discretionary Acts
The remedy portion of the holding produced a second doctrine that still matters. Marshall drew a line between two kinds of executive action. Some duties are discretionary: the officer carries out the President’s will and answers to the President, and courts have no role in reviewing those choices. Foreign policy and political appointments fall on that side of the line. Other duties are ministerial: the law directs the officer to do a specific thing, and no personal judgment is involved. Ministerial duties are enforceable by mandamus.3Justia. Marbury v Madison, 5 US 137 (1803)
That framework remains part of how courts sort which government actions they can review and which they cannot, and it is one of the roots of the modern political question doctrine.
How the Holding Has Been Used Since
After 1803, the Supreme Court did not strike down another federal statute for more than fifty years. The next instance was Dred Scott v. Sandford (1857), which invalidated the Missouri Compromise.8Federal Judicial Center. Marbury v Madison (1803) The long gap reflects how sparingly the early Court used the power Marshall had claimed. Since then the Court has invalidated portions of well over a hundred federal statutes, along with countless state and local laws.
Every time the Court evaluates whether a federal agency has exceeded its statutory authority, whether a state law violates the Bill of Rights, or whether an executive order oversteps the separation of powers, it is exercising the authority first asserted in Marbury. The rule that courts can refuse to enforce laws that conflict with the Constitution is the structural foundation of American constitutional law.
