(CNN)Here is a look at the Supreme Court of the United States.
The U.S. Supreme Court was created in accordance with Article III, section 1 of the Constitution of the United States and by the authority of the Judiciary Act of September 24, 1789.
February 2, 1790 - The first court assembles in New York City.
Nine Justices comprise the U.S. Supreme Court, one chief justice and eight associate justices.
The number of associate justices may be fixed by Congress and under the authority of the act of June 25, 1948 (28 U.S.C. 1).
The President of the United States nominates candidates for the Supreme Court. They must be approved by the U.S. Senate.
Approval process for the Chief Justice is the same as it is for the Associate Justices.
Once approved, all justices serve for life. Congress can remove a justice through impeachment for corrupt behavior or other abuses of office, but this has never happened.
Chief Justices are sworn in by the outgoing Chief Justices. Other Justices (Associate Justices) are sworn in by the current Chief Justice or one of the other Associate Justices.
Each justice oversees at least one of the twelve (12) Federal Judicial Circuit Courts.
