What is the US Supreme Court?
The US Supreme Court is the head of the Judicial branch of
government, and is the highest appellate court, for federal cases
and state cases that involve questions of federal or constitutional
law, in the United States. The Court also has original jurisdiction
over a restricted class of cases.
The Supreme Court is the final arbiter of the US Constitution,
and has the authority of judicial review, which allows it to
nullify unconstitutional laws if they are legally challenged
and brought before the Court.
