Supreme Court of the United States

Highest federal court with ultimate appellate and original jurisdiction.

Supreme Court of the United States

The Supreme Court of the United States, often called SCOTUS, sits at the top of the federal court system. It hears final appeals from all federal courts and from state courts when the case involves the U.S. Constitution or federal law. The Court also handles a small set of cases directly, such as those involving ambassadors or disputes where a state is a party. In 1803, the Court claimed the power of judicial review, meaning it can throw out a law if it conflicts with the Constitution. It can also overturn presidential orders that break the Constitution or federal statutes.

The Court’s structure and rules were set by the first Congress in the Judiciary Act of 1789, based on Article Three of the Constitution. Today, it has nine justices: one chief justice and eight associate justices. They work in the Supreme Court Building in Washington, D.C. Justices serve for life—unless they die, retire, resign, or are removed through impeachment. When a seat opens, the president picks a replacement, and the Senate must confirm the choice.

Each justice gets one vote on cases. If the chief justice is in the majority, they decide who writes the Court’s opinion; otherwise, the most senior justice in the majority makes that call. Justices can write separate opinions agreeing (concurrences) or disagreeing (dissents), and others may join them. Each year, the Court gets about 7,000 requests for review, but it only hears around 80.

**History**

In 1787, four years after the Revolutionary War ended, delegates at the Constitutional Convention in Philadelphia argued over how to split power between Congress and the president. They also set up a national judiciary as a third branch. Before that, British tradition put judicial matters under the king’s authority. Some delegates, wary of a strong central government, thought state courts could enforce national laws. James Madison and others wanted a national court chosen by Congress. There was talk of letting the judiciary check the executive by vetoing or revising laws.

The framers compromised by sketching only a basic outline of the judiciary in Article Three. They gave federal judicial power to “one supreme Court” and any lower courts Congress might create. They didn’t spell out the Court’s exact powers or how it should be run.

Lore & Background

The Supreme Court was established by the 1st Congress through the Judiciary Act of 1789, following the outline in Article Three of the U.S. Constitution. The first six justices—a chief justice and five associates—were nominated by President George Washington and confirmed by the Senate in September 1789. The court held its inaugural session in February 1790 at the Royal Exchange in New York City, then the U.S. capital. Early sessions were devoted to organizational proceedings, with the first cases reaching the court in 1791. The court moved with the capital to Philadelphia in 1790 and later to Washington, D.C., where it met in the U.S. Capitol Building until 1935, when it moved to its own building.

Under Chief Justice John Marshall (1801–1835), the court established the power of judicial review in Marbury v. Madison and made important rulings on federal-state balance. The court's size was last changed in 1869, when it was set at nine justices. Justices have lifetime tenure, serving until death, retirement, resignation, or impeachment and removal. Each justice has a single vote; the chief justice assigns the opinion of the court when in the majority, otherwise the most senior justice in the majority does so. The court receives about 7,000 petitions for certiorari each year but grants only about 80.

Reader's Guide

The Supreme Court of the United States is significant as the final arbiter of constitutional and federal law, shaping American legal and political life through its power of judicial review. Its decisions have addressed fundamental issues such as federal power, civil rights, and the balance between government branches. The court's composition—nine justices with lifetime appointments—ensures continuity but also makes appointments politically consequential. The court's early lack of prestige grew substantially under the Marshall Court, which established judicial review and ended the practice of seriatim opinions. Later courts, such as the Warren Court, expanded constitutional civil liberties. The court's ability to invalidate both statutes and presidential directives makes it a key check on the other branches. Its limited caseload—granting only about 80 of 7,000 annual petitions—allows it to focus on cases of national importance. The court's history reflects ongoing debates about federal power, individual rights, and the role of the judiciary in a democratic system.
