Article III - The Judicial Branch

Article III of the Constitution of the United States establishes the federal government's judicial branch. The text of the Constitution only references the Supreme Court, but it gave the Senate and House of Representatives the power to create lower courts (known as “inferior courts") as necessary.

The fact that the Constitution only establishes one federal court says a lot about what the Framers were thinking when they were setting up a new government after the Revolutionary War. Many at the Constitutional Convention feared a strong central government would be too similar to the monarchy and advocated for the states to have more power. But others argued that leaving the interpretation of federal law up to state courts would mean the federal government would never get anything done.

In 1789, Congress set up the Supreme Court, which then had six justices. Today, there are nine Supreme Court justices, including the Chief Justice.

For more than 100 years, the Supreme Court was responsible for hearing all appeals in federal court cases. Then, Congress passed the Judiciary Act of 1891, also known as the Evarts Act. The Evarts Act created the U.S. Court of Appeals, a system of federal appellate courts tasked with reducing the workload of the Supreme Court. Congress divided this new court system into nine circuits and assigned a “circuit justice" to each.

If a party disagrees with the decision of a federal district court, they can appeal to have the decision reviewed by a three-judge panel in their circuit. Today, there are twelve federal circuits. The Evarts Act greatly limited the types of cases that could be appealed to the Supreme Court, giving appellate jurisdiction in most cases to the U.S. Court of Appeals.
