What Is Marbury v. Madison? The Case That Gave Courts the Power to Strike Down Unconstitutional Laws

A Missing Piece of Paper That Reshaped American Government

In the final hours of his presidency, John Adams signed a stack of judicial appointments late into the night. One of those appointments, a commission naming William Marbury as a justice of the peace for the District of Columbia, was signed and sealed but never delivered. When Thomas Jefferson took office days later, his new Secretary of State, James Madison, was ordered not to hand it over.

What followed was a lawsuit over a single undelivered piece of paper. What the Supreme Court did with that lawsuit became, by most accounts, the most consequential decision in the history of American constitutional law. Marbury v. Madison (1803) established the principle of judicial review: the authority of federal courts to declare an act of Congress void if it conflicts with the Constitution.

This article explains what the case actually involved, how it connects to a separate and often-confused piece of legislation called the Judiciary Act of 1801, what the Supreme Court actually decided, and why the decision still defines the relationship between the courts, Congress, and the President more than two centuries later.

The Political Background: The Election of 1800 and the Judiciary Act of 1801

To understand Marbury v. Madison, it helps to understand the political chaos that preceded it.

The election of 1800 was a bitter contest between the Federalist Party, led by incumbent President John Adams, and the Democratic-Republicans, led by Thomas Jefferson. Jefferson won the presidency, and his party also won control of both chambers of Congress. For the Federalists, this was a near-total loss of political power, with one exception: the judiciary, where Federalist-appointed judges held lifetime positions that the incoming administration could not simply remove.

In the final months before Jefferson’s inauguration, the outgoing Federalist Congress passed the Judiciary Act of 1801. This law reorganized the federal court system, created new circuit courts, and crucially, created a number of new judgeships, including 42 new justice of the peace positions for the District of Columbia. President Adams moved quickly to fill these new positions with Federalist appointees before leaving office. Because many of these commissions were signed and sealed in the last days, and in some cases the last hours, of the Adams administration, the appointees became known to history as the “midnight judges.”

William Marbury was one of these appointees. His commission as a justice of the peace was signed by Adams and sealed by the acting Secretary of State, who at the time happened to be John Marshall, the same man who would soon become Chief Justice of the Supreme Court and write the Marbury opinion. But in the rush of the transition, Marbury’s commission was never physically delivered to him.

When Jefferson took office on March 4, 1801, he viewed the Judiciary Act of 1801 and the midnight appointments as a blatant attempt by the defeated Federalists to entrench their influence in the one branch of government they still controlled. Jefferson instructed his new Secretary of State, James Madison, not to deliver the remaining undelivered commissions, including Marbury’s. The new Democratic-Republican Congress went further, repealing the Judiciary Act of 1801 entirely in 1802 and replacing it with a new judiciary act that restored much of the structure that had existed before 1801.

It is important to understand what the Judiciary Act of 1801 did and did not do in relation to the Marbury case itself. The 1801 Act is the law that created the position Marbury was appointed to, and the broader political dispute over that Act, and its repeal, is the backdrop against which the entire controversy unfolded. But the 1801 Act itself was not the law the Supreme Court ultimately ruled unconstitutional. That distinction belongs to a different, earlier statute: the Judiciary Act of 1789.

The Lawsuit: Marbury Sues for His Commission

Having been denied his commission, Marbury did something that, at the time, seemed procedurally straightforward. He went directly to the United States Supreme Court and asked for a writ of mandamus, a court order compelling a government official to perform a duty they are legally required to perform. In this case, Marbury wanted the Court to order Madison to deliver his commission.

Marbury’s lawyer, Charles Lee, who had served as Attorney General under Adams, argued that the Supreme Court had the authority to issue this writ directly, without the case first going through a lower court. He based this argument on Section 13 of the Judiciary Act of 1789, the foundational law that had established the federal court system more than a decade earlier. Section 13 appeared to authorize the Supreme Court to issue writs of mandamus in cases falling within its original jurisdiction, meaning cases the Court could hear directly rather than on appeal from a lower court.

The Jefferson administration, for its part, largely ignored the lawsuit. Madison did not appear, and the government did not formally contest the case. This left Chief Justice John Marshall in an extraordinarily delicate, and personally awkward, position. As outgoing Secretary of State under Adams, Marshall had personally signed the official seal onto Marbury’s commission. The job of physically delivering it had fallen to Marshall’s own brother, James, who returned several commissions, including Marbury’s, when he found he could not carry them all before the administration’s term ended. The undelivered commission at the center of the lawsuit was, in other words, a loose end from Marshall’s own tenure in the executive branch.

Marshall did not recuse himself. Two of the six justices on the Court, William Cushing and Alfred Moore, did not participate in the case, but Marshall not only sat on it, he wrote the unanimous opinion deciding it, ruling on the legal consequences of his own prior conduct as Secretary of State. By modern judicial standards this would almost certainly call for recusal, and it remains one of the most frequently noted aspects of the case. At the time, however, recusal standards focused narrowly on direct financial interests, and contemporary critics of the decision, even Marshall’s political opponents, did not raise the issue.

The Three Questions Marshall Had to Answer

When the Court issued its decision on February 24, 1803, Chief Justice Marshall structured the opinion around three sequential questions. The structure of these questions, and the order in which Marshall answered them, is what made the decision so consequential.

First: Did Marbury have a legal right to his commission?

Marshall said yes. Once the President signed the commission and the Secretary of State affixed the official seal, the appointment was legally complete. Delivery of the physical document was a formality that did not affect the underlying legal right. Marbury was entitled to the commission, and withholding it was a violation of that right.

Second: If Marbury had a legal right, did the law provide him a remedy?

Marshall again said yes, in sweeping terms. He articulated a foundational principle of American law: where there is a legal right, there must be a legal remedy. A government that could violate individual rights without any judicial recourse would not truly be a government of laws. Madison’s refusal to deliver the commission was, in Marshall’s words, a plain violation of Marbury’s legal rights, and the law afforded him a remedy in the form of a writ of mandamus.

Third: Was a writ of mandamus from the Supreme Court the correct remedy, and could the Supreme Court issue it in this case?

This is where the opinion took its decisive turn. Marbury had brought his case directly to the Supreme Court, relying on Section 13 of the Judiciary Act of 1789 as the source of the Court’s authority to hear it. But Marshall examined Article III, Section 2 of the Constitution, which defines the Supreme Court’s original jurisdiction, the narrow category of cases the Court can hear directly without first going through a lower court. Article III lists only a small number of case types within that original jurisdiction, primarily cases involving ambassadors, public ministers, and disputes between states. A case seeking a writ of mandamus against a Secretary of State was not among them.

Section 13 of the Judiciary Act of 1789, as Marshall read it, purported to give the Supreme Court original jurisdiction over this type of case anyway, expanding the Court’s original jurisdiction beyond what Article III of the Constitution permitted. Marshall held that Congress could not do this. A statute that conflicts with the Constitution, he reasoned, cannot stand. The Constitution is the supreme law of the land, and any legislative act repugnant to it is void.

Therefore, Marshall concluded, Section 13 of the Judiciary Act of 1789 was unconstitutional to the extent it attempted to expand the Supreme Court’s original jurisdiction beyond what Article III allowed. Because the Court lacked jurisdiction to hear Marbury’s case as an original matter, it could not issue the writ of mandamus, regardless of how clearly Marbury’s underlying rights had been violated.

Why This Outcome Was So Strategically Brilliant

On its face, the ruling was a loss for Marbury. He never got his commission. It was also, in a narrow sense, a political win for Jefferson and Madison, since the Court did not order them to do anything.

But the substance of the ruling went much further than the outcome for Marbury himself. In the course of explaining why the Supreme Court could not hear this particular case, Marshall established something far more significant: that the judiciary has the authority to examine acts of Congress and declare them void if they conflict with the Constitution. This was the first time the Supreme Court had struck down a federal statute on constitutional grounds.

The strategic brilliance of the decision lay in its sequencing. Marshall first established that Marbury was right on the merits and that Madison’s conduct was illegal, which satisfied Federalists who wanted the Jefferson administration’s conduct condemned. He then declined to issue any order the administration might defy, which avoided a direct confrontation the young Court could not have won. And in the process of explaining that refusal, he claimed for the judiciary a power, the power of judicial review, far more enduring than any single writ of mandamus could have been.

As Marshall wrote in the opinion, it is emphatically the province and duty of the judicial department to say what the law is. That sentence, more than any other in the opinion, became the foundation of the American judiciary’s role for the next two centuries.

The week that followed underscores just how carefully Marshall was navigating the moment. Six days after deciding Marbury, the Court issued its decision in Stuart v. Laird, a case that tested the constitutionality of the very 1802 repeal of the Judiciary Act of 1801 that had eliminated the midnight judges’ circuit court positions. Having just claimed, in Marbury, the power to strike down an act of Congress, Marshall might have used that same power to invalidate the repeal he personally disagreed with. He did not. Marshall did not even participate in the decision, and the remaining justices upheld the 1802 repeal, allowing Congress’s reorganization of the courts to stand. The Court had asserted the principle of judicial review against a narrow, procedural provision of the Judiciary Act of 1789 while declining to apply that same principle to the far more politically explosive repeal of the Judiciary Act of 1801, the very Act whose appointments had created Marbury’s claim in the first place.

What Judicial Review Means in Practice

Judicial review is the power of courts to assess whether a law, regulation, or government action complies with the Constitution, and to refuse to enforce it if it does not.

The Constitution does not explicitly grant federal courts this power. Article III establishes the judicial branch and describes the types of cases federal courts may hear, but it does not contain a sentence stating that courts may strike down unconstitutional laws. Marbury v. Madison is the source of that power as American constitutional law has developed it. Since 1803, the Supreme Court has extended the logic of judicial review well beyond its original context, applying it to state statutes, federal regulations, and executive actions, not just the specific type of federal statute at issue in Marbury itself.

It is worth noting how rarely this power was actually used in the decades immediately following Marbury. The Supreme Court did not strike down another federal law on constitutional grounds until the Dred Scott decision in 1857, fifty-four years later. Judicial review’s significance was not that courts immediately began striking down laws at scale. Its significance was establishing, as a matter of settled constitutional principle, that they could.

Why This Case Still Matters for Constitutional Litigation Today

The principle established in Marbury v. Madison is the doctrinal foundation underlying virtually every constitutional challenge brought in American courts today, including the kinds of cases that define Constitutional Law practice at Kassouni Law. When a property owner challenges a government permit condition as exceeding what the Constitution allows, when a litigant argues that a state law conflicts with a constitutional protection, or when a court is asked to determine whether a government agency has acted within the bounds the Constitution sets, the underlying premise, that courts have the authority to make that determination and that their conclusion binds the other branches of government, traces directly back to Marshall’s 1803 opinion.

The firm’s own published analysis of Marbury v. Madison describes the decision as having established the precedent by which the government still operates today: that the legislative and executive branches cannot conduct business in an unconstitutional manner, and that the judiciary has the ultimate authority to determine compliance with the Constitution. That principle is not an abstract historical footnote. It is the reason a court can examine whether a government agency’s permit conditions satisfy the Nollan/Dolan test, whether a fee schedule complies with the Takings Clause, or whether an enforcement action satisfies due process. Every one of those inquiries depends on the premise that courts have the authority to say what the Constitution requires, and that a government action inconsistent with it cannot stand.

The Constitutional Property Rights practice at Kassouni Law and the firm’s broader appellate work rest on exactly this foundation: the conviction, established in 1803 and tested in courts ever since, that constitutional limits on government power are enforceable, and that the judiciary is the institution responsible for enforcing them.

Frequently Asked Questions

What is Marbury v. Madison and why is it important?

Marbury v. Madison (1803) is a United States Supreme Court decision that established the principle of judicial review, the authority of federal courts to declare an act of Congress unconstitutional and therefore unenforceable. The case arose from a dispute over an undelivered judicial commission, but its lasting significance lies in Chief Justice John Marshall’s holding that the Constitution is the supreme law of the land and that it is the role of the judiciary to determine when a law conflicts with it. It is widely regarded as the single most important decision in American constitutional law because it established the framework through which courts review the constitutionality of government action to this day.

What is the connection between Marbury v. Madison and the Judiciary Act of 1801?

The Judiciary Act of 1801, passed by the outgoing Federalist Congress in the final weeks of John Adams’ presidency, reorganized the federal courts and created the new judicial positions, including the justice of the peace position William Marbury was appointed to. The political controversy surrounding the Act, its midnight appointments, and its subsequent repeal by the incoming Jefferson administration forms the backdrop of the dispute. However, the Judiciary Act of 1801 was not the law the Supreme Court declared unconstitutional in Marbury v. Madison. That distinction belongs to Section 13 of the separate and earlier Judiciary Act of 1789, which the Court found had improperly expanded its original jurisdiction beyond what Article III of the Constitution permits.

Did William Marbury ever get his commission?

No. The Supreme Court held that Marbury had a legal right to the commission and that withholding it was illegal, but the Court also held that it lacked jurisdiction to issue the writ of mandamus that would have compelled its delivery. Because the provision of the Judiciary Act of 1789 that Marbury relied on to bring his case directly to the Supreme Court was found unconstitutional, the Court could not grant the remedy regardless of the merits of his underlying claim. Marbury never served as a justice of the peace. Notably, the commission had gone undelivered during Chief Justice John Marshall’s own prior tenure as Secretary of State, and Marshall, without recusing himself, was the one who ultimately authored the opinion explaining why the Court could not order its delivery.

What does it mean that a law is “unconstitutional”?

A law is unconstitutional when it conflicts with the Constitution, the foundational legal document that establishes the structure, powers, and limits of the federal government and protects individual rights. Under the principle of judicial review established in Marbury v. Madison, when a court finds that a statute conflicts with the Constitution, that statute cannot be enforced, regardless of whether Congress validly passed it through the normal legislative process. The Constitution functions as a higher law that ordinary legislation cannot override.

How does Marbury v. Madison relate to constitutional property rights cases today?

Every constitutional challenge to government action, including the kinds of property rights cases litigated by Kassouni Law, depends on the premise established in Marbury v. Madison: that courts have the authority to determine whether a government action is consistent with the Constitution, and that an action found to violate the Constitution cannot stand regardless of which branch of government took it. Whether the question involves a permit condition, a fee schedule, an eminent domain proceeding, or a regulatory restriction, the ability of a court to evaluate that government action against constitutional standards, and to provide a remedy where the Constitution has been violated, is the legacy of the framework Chief Justice Marshall articulated in 1803.
