Supreme Court of the United States

There are 9 justices on the court now: one Chief Justice and eight Associate Justices. Courts (a set of all justices of the court while one Chief Justice is serving) are unofficially named for the Chief Justice; the current Court is called the "Roberts Court" after Chief Justice John Roberts.

The Supreme Court chooses which cases it will decide on, by choosing to give a writ of certiorari or not.^[1] Almost 7,000 people, known as petitioners, ask the Supreme Court to decide their cases every year, but the court only gives a writ to about 100 or less.^[2] For the Supreme Court to decide a case, the case must be about: federal law, the Constitution of the United States, disagreements between states or their residents, or another court's decision that differs from what the Supreme Court has decided on a similar case. Cases must first be decided by a federal district court and a federal court of appeals or by a state supreme court. Even after that, the Supreme Court can choose not to decide a case for any reason. Cases about disagreements between states or their residents sometimes can only be decided by the Supreme Court, but those are rare.

The justices serve for life unless they want to retire earlier or are impeached. If a justice retires, he or she can still be asked to serve as a judge on a federal Court of Appeals. New justices are nominated (picked) by the President of the United States, and then must be approved by the United States Senate.

The most recent justice to be chosen is Ketanji Brown Jackson, who was nominated by President Joe Biden in February 2022, to replace retiring Justice Stephen Breyer. After the Senate approved her, Jackson became the first female African American justice.^[3]
