The Judicial Review power of the U.S. Supreme Court refers to its authority to examine laws and executive actions and determine whether they are in accordance with the U.S. Constitution. If a law is found to be unconstitutional, the Court can strike it down. This power was established in the landmark case Marbury v. Madison (1803), where Chief Justice John Marshall asserted that it is the duty of the judiciary to interpret the law and uphold the Constitution as the supreme law of the land. Judicial review allows the Court to:
- Invalidate federal and state laws that conflict with the Constitution.
- Check the powers of the legislative and executive branches.
- Protect the fundamental rights and liberties of citizens.
