Supreme Court of the United States

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all U . federal court cases, and over state court cases that turn on questions of U . constitutional or federal law. It also has original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party". In 1803, the court asserted itself the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution. It is also able to strike down presidential directives for violating either the Constitution or statutory law. Under Article Three of the United States Constitution, the composition and procedures of the Supreme Court were originally established by the 1st Congress through the Judiciary Act of 1789. As currently constituted the court consists of nine justices—the chief justice of the United States and eight associate justices—who meet at the Supreme Court Building in Washington, D . Justices have lifetime tenure, meaning they remain on the court until they die, retire, resign, or are impeached and removed from office. When a vacancy occurs, the president, with the advice and consent of the Senate, appoints a new justice. Each justice has a single vote in deciding the cases argued before the court. When in the majority, the chief justice decides who writes the opinion of the court; otherwise, the most senior justice in the majority assigns the task. A justice may write an opinion in concurrence with the court, or they may write a dissent, and these concurrences or dissents may also be joined by other justices. On average, the Supreme Court receives about 7,000 petitions for writs of certiorari each year, but only grants about 80.
