The Judiciary Act of 1789 was a landmark piece of legislation that meticulously outlined the structure and jurisdiction of the United States federal court system. Signed into law by President George Washington, this act went far beyond simply creating a Supreme Court; it established a multi-tiered judicial framework designed to administer justice across the newly formed nation. Its provisions detailed the composition of the highest court, the creation
of lower federal courts, and the establishment of key legal offices, all essential for the functioning of a unified federal government.
The Supreme Court and its Powers
At the apex of the newly formed federal judiciary, the Judiciary Act of 1789 established the Supreme Court. The act specified that the Supreme Court would consist of a Chief Justice and five Associate Justices, totaling six members. It also mandated that any four of these justices would constitute a quorum, allowing the Court to conduct business. Furthermore, the act stipulated that the Supreme Court would hold two annual sessions at the seat of government, commencing on the first Monday of February and the first Monday of August.
The act carefully defined the Supreme Court's jurisdiction. It was granted exclusive original jurisdiction over all civil actions between states, or between a state and the United States. This meant that such cases could only be initiated in the Supreme Court. Additionally, the Court held exclusive original jurisdiction over all suits and proceedings brought against ambassadors and other diplomatic personnel. For other cases where a state was a party or cases brought by an ambassador, the Court had original, but not exclusive, jurisdiction. Beyond its original jurisdiction, the Supreme Court was also given crucial appellate jurisdiction over decisions from federal circuit courts, as well as certain decisions from state courts. This appellate power extended to state court rulings that invalidated a U.S. statute or treaty, upheld a state law challenged as inconsistent with federal law, or rejected a claim made under the federal constitution, treaties, or laws, ensuring a mechanism for federal oversight and uniformity.
Establishing Lower Federal Courts and Districts
Beyond the Supreme Court, the Judiciary Act of 1789 was instrumental in creating a network of lower federal courts. It established 13 judicial districts within the 11 states that had ratified the Constitution at that time. North Carolina and Rhode Island were added as judicial districts in 1790, with other states incorporated as they joined the Union. Each state generally comprised one district, with the notable exceptions of Virginia and Massachusetts, which each contained two. Massachusetts was divided into the District of Maine (which was then part of Massachusetts) and the District of Massachusetts (covering modern-day Massachusetts). Similarly, Virginia was split into the District of Kentucky (then part of Virginia) and the District of Virginia (encompassing modern-day West Virginia and Virginia).
Within each of these judicial districts, the act established both a circuit court and a district court. The only exceptions were Maine and Kentucky, where the district courts were granted much of the jurisdiction typically held by circuit courts. The circuit courts were composed of a district judge and, initially, two Supreme Court justices who would "ride circuit" – traveling to hear cases. These circuit courts had original jurisdiction over serious crimes and civil cases involving at least $500, particularly those involving diversity jurisdiction (disputes between citizens of different states) or cases where the United States was the plaintiff in common law and equity. They also held appellate jurisdiction over the district courts. The single-judge district courts primarily handled admiralty cases, petty crimes, and suits by the United States for at least $100. Notably, the act did not grant original federal question jurisdiction to these federal courts at this time, highlighting diversity jurisdiction as an "original" and "ancient" aspect of federal court authority.
New Offices and the Alien Tort Statute
In addition to structuring the courts, the Judiciary Act of 1789 created several vital offices to support the federal judiciary. It established the Office of Attorney General, whose primary responsibility was to represent the United States before the Supreme Court. Furthermore, the act mandated the creation of a United States attorney and a United States marshal for each judicial district. These roles were crucial for prosecuting federal crimes and enforcing federal laws and court orders across the country.
Another significant inclusion in the Judiciary Act of 1789 was the Alien Tort Statute, now codified as 28 U.S.C. § 1350. This statute provided jurisdiction in the district courts for lawsuits brought by aliens for torts (civil wrongs) committed in violation of the law of nations or treaties of the United States. This provision, described as a "powerful device to assert the primacy of the national judicial power over that of the states," also introduced the concept of removal jurisdiction, allowing persons sued by citizens of another state in the plaintiff's home state court to transfer the lawsuit to a federal circuit court. This innovation was a key mechanism for asserting federal judicial authority.
