The Judiciary Act of 1789 was the statute the first Congress passed to build the federal court system from the ground up. Signed into law on September 24, 1789, it turned a single sentence in Article III of the Constitution into a working judiciary: a Supreme Court with a fixed number of justices, a network of trial courts covering every state, and the officers needed to prosecute cases and enforce orders.1Legal Information Institute. U.S. Constitution – Article III Article III had created “one Supreme Court” and left everything else, including how many judges to appoint, what cases they could hear, and how their rulings would be enforced, for Congress to decide. The Act filled those gaps, and much of what it built is still standing.
The Three-Tier Court System It Created
The Act organized the federal judiciary into three levels.2Federal Judicial Center. Judiciary Act of 1789 Establishes Federal Courts
At the top was the Supreme Court, composed of a Chief Justice and five Associate Justices, with any four making a quorum.3National Archives. Judiciary Act of 1789 That number of justices changed repeatedly over the following decades before Congress settled on nine in 1869.
At the bottom sat thirteen district courts, roughly one per state plus separate districts for the then-territories of Kentucky and Maine.4Supreme Court of the United States. The Court as an Institution A single district judge ran each one. These courts handled admiralty and maritime cases, seizures under trade and navigation laws, minor federal criminal offenses, and civil suits brought by the United States worth more than one hundred dollars.5The Avalon Project. The Judiciary Act – September 24, 1789 Jury trials were guaranteed in district courts for everything except admiralty cases.
In between were circuit courts. Eleven of the thirteen districts were grouped into three circuits (the Eastern, the Middle, and the Southern), with Maine and Kentucky left out of the grouping. Each circuit court was staffed by two Supreme Court justices and the local district judge sitting together, any two of them making a quorum.3National Archives. Judiciary Act of 1789 Circuit courts served as the principal federal trial courts for more serious cases and had limited appellate review over the district courts.2Federal Judicial Center.

Requiring the justices to ride circuit turned out to be brutal on them, and by 1792 they had formally complained to President Washington that the travel was unbearable. Congress reduced the requirement from two justices per circuit to one in 1793, but the burden did not fully disappear until the Evarts Act of 1891 created a separate tier of federal appellate courts.6Federal Judicial Center.

What Cases Federal Courts Could Hear
Building the courts was one thing; deciding what they could do was another. The Act defined federal jurisdiction across several categories.
Supreme Court Original and Appellate Jurisdiction
Section 13 gave the Supreme Court two kinds of authority. For a narrow set of disputes, the Court was the first and only forum. It had exclusive original jurisdiction over civil cases where a state was a party (except suits between a state and its own citizens), and original but non-exclusive jurisdiction over cases involving foreign diplomats or disputes between a state and citizens of another state.5The Avalon Project. The Judiciary Act – September 24, 1789 For everything else, the Court worked as an appellate body, reviewing federal legal questions decided by the courts below.
Diversity Jurisdiction Between Citizens of Different States
Section 11 let circuit courts hear ordinary lawsuits between citizens of different states when the amount in dispute exceeded five hundred dollars, provided at least one party was a citizen of the state where the suit was filed.7Legal Information Institute. Overview of Diversity Jurisdiction The concern was practical: a merchant from one state sued in another state’s courts could face local bias, and a federal forum offered neutrality.
Section 12 gave out-of-state defendants and foreign nationals a way to move a qualifying case out of state court and into federal circuit court, so long as they acted at their first appearance and posted a bond. A separate removal procedure existed for land-title disputes where both parties were from the same state but claimed under grants from different states.5The Avalon Project. The Judiciary Act – September 24, 1789
Congress later broadened diversity jurisdiction. An 1875 law dropped the requirement that one party live in the forum state. Today, federal diversity jurisdiction under 28 U.S.C. ยง 1332 requires the amount in controversy to exceed $75,000.
Writs of Mandamus, Prohibition, and Habeas Corpus
Federal courts also needed tools to compel action and stop overreach. Section 13 authorized the Supreme Court to issue writs of mandamus (orders directing a federal officer to perform a legal duty) and writs of prohibition (orders forbidding a lower court or official from exceeding lawful authority).
Section 14 gave all federal courts the power to issue writs of habeas corpus, letting a federal judge order that a prisoner be brought in so the judge could examine whether the detention was lawful.5The Avalon Project. The Judiciary Act – September 24, 1789 The Act limited this power to people held under federal authority or awaiting trial in a federal court, so it did not initially reach prisoners held by state governments. That limitation would not fully change until after the Civil War.
Supreme Court Review of State Court Decisions
Section 25 was arguably the Act’s most controversial provision. It let the Supreme Court review and reverse final decisions from the highest state courts whenever a state court had struck down a federal law, upheld a state law over a conflicting federal one, or ruled against a right claimed under the Constitution or a federal treaty.8Federal Judicial Center. Supreme Court Jurisdiction Expanded Without it, each state’s top court would have had the final word on what federal law meant within its borders, and the Constitution could have come to mean different things in different states.
Section 25 put teeth into the Supremacy Clause of Article VI, which declares the Constitution, federal statutes, and treaties the supreme law of the land.9Legal Information Institute. Federal-State Court Relations – Overview The Supreme Court upheld its validity in Martin v. Hunter’s Lessee in 1816, holding that federal appellate power “does extend to cases pending in the State courts” and that Section 25 was “supported by the letter and spirit of the Constitution.”10Justia U.S. Supreme Court. Martin v. Hunter’s Lessee, 14 U.S. 304 (1816) Chief Justice John Marshall reinforced the point in Cohens v. Virginia five years later.
The Officers Who Staffed and Enforced the Courts
A court system needs people to run it. The Act created three categories of federal legal officers.
Section 35 established the Attorney General as the federal government’s top legal officer. The original job was much narrower than today’s cabinet role: handle Supreme Court litigation for the United States and advise the President and department heads on legal questions when asked.11GovInfo. Judiciary Act of 1789 – 1 Stat. 73 There was no Department of Justice and no staff.
The Act also placed a United States Attorney in each judicial district to prosecute federal cases locally, and a United States Marshal in each district to serve as the court’s enforcement arm. Section 27 spelled out the marshal’s duties: attend every session of the district and circuit courts, execute all lawful orders issued under federal authority, and appoint deputies as needed. Each marshal had to post a twenty-thousand-dollar bond and swear an oath to act without malice or partiality.5The Avalon Project. The Judiciary Act – September 24, 1789
Marshals quickly became the federal government’s only visible presence in most of the country. Congress assigned them the first national census in 1790, a duty they kept until 1870, and they also protected tax collectors during the Whiskey Rebellion and chased counterfeiters before the Secret Service existed.12U.S. Marshals Museum. Origins and Early Days of the U.S. Marshals
Marbury v. Madison and the Section 13 Problem
The Act’s most famous legal consequence came from a provision the Supreme Court eventually struck down. In 1803, William Marbury asked the Court to use its original jurisdiction under Section 13 to issue a writ of mandamus forcing Secretary of State James Madison to deliver his judicial commission. Chief Justice John Marshall agreed that Section 13 authorized exactly that kind of order.13Constitution Annotated. Marbury v. Madison and Judicial Review
Then Marshall did something no court had done before. He held that Congress could not expand the Supreme Court’s original jurisdiction beyond what Article III already specified, so Section 13’s mandamus provision was void. The result was the doctrine of judicial review: the principle that federal courts can declare an act of Congress unconstitutional and refuse to enforce it. Marshall framed the point in words that have been quoted ever since: “It is emphatically the province and duty of the judicial department to say what the law is.”14Legal Information Institute. Marbury v. Madison and Judicial Review
Judicial review has no explicit basis in the Constitution’s text. It exists in part because the 1789 Act gave Marshall the vehicle to find it.
What Still Survives Today
Much of the Act’s original architecture is still in place. The federal courts still run on a three-tier model of district courts, appellate courts, and the Supreme Court. U.S. Marshals still enforce federal court orders. U.S. Attorneys still prosecute federal cases in each district. The Attorney General still serves as the government’s chief legal officer, though the role has grown enormously. The Supreme Court still reviews state court decisions on questions of federal law under the same principle Section 25 established.
Details have changed repeatedly. The number of justices rose and fell before settling at nine. Circuit riding disappeared. The diversity threshold climbed from five hundred dollars to seventy-five thousand. Congress created the Department of Justice in 1870 and reorganized the appellate courts in 1891.6Federal Judicial Center.
