What is the significance of Marbury v. Madison?

• A. It established the right to free speech
• B. It established the principle of judicial review
• C. It expanded the powers of Congress
• D. It limited the power of the President

Answer: (B)

Marbury v. Madison is significant primarily because it established the principle of judicial review, a fundamental aspect of the American legal and constitutional framework. This landmark Supreme Court case in 1803 determined that it is the role of the judiciary to interpret the law and ensure that no laws or executive actions are in conflict with the Constitution. Chief Justice John Marshall asserted that the Constitution is the supreme law of the land, and it is the duty of the courts to uphold it.

As a result, this case granted the Supreme Court the authority to invalidate laws and actions that it deemed unconstitutional, effectively providing a check on the legislative and executive branches of government. This principle has greatly influenced how laws are interpreted and enforced in the United States, ensuring that all branches of government operate within the confines set by the Constitution. Thus, Marbury v. Madison laid the groundwork for the judiciary's role in maintaining constitutional governance and the balance of power among the branches.
