In the U.S., the Supreme Court is the highest court in the land. It serves as the final judge in all Congressional laws and the ultimate interpreter of the Constitution. The Supreme Court is often referred to as "the court of last resort."
The creation of the Supreme Court is provided in the U.S. Constitution. Congress has the authority for its organization, while the President has the power to appoint Supreme Court justices. All appointed justices need to be confirmed by the Senate before they can be seated. This system of checks and balances ensures that each branch of government does not go beyond the limits of its own power.
