POWER OF THE SUPREME COURT

The Supreme Court is the only court mentioned by name in the Constitution. Article III establishes the Court as the top of the country’s judicial branch, making it equal to the executive branch (the president) and the legislative branch (Congress). Article III also gives the Court jurisdiction (authority to review) over broad classes of cases. In 1803 in Marbury v. Madison the Court interpreted its own authority, ruling that the Constitution gave it the power to strike down unconstitutional acts of government—that is, laws or other government conduct that violate the Constitution. This decision created the power of judicial review, an essential component in the American system of checks and balances, a system that is intended to safeguard Americans from government abuses of power.
