What is judicial review?

• A. The ability of courts to review executive actions
• B. The power of the courts to declare laws unconstitutional
• C. The process of reviewing judicial appointments
• D. The review of state laws by the federal government

Answer: (B)

Judicial review refers to the power of the courts to declare laws unconstitutional, which is pivotal in maintaining the checks and balances among the branches of government. This principle emerged from the landmark Supreme Court case Marbury v. Madison in 1803, where Chief Justice John Marshall established that it is the duty of the judicial system to interpret the law and ensure that no law or executive action conflicts with the Constitution. This function allows the judiciary to act as a guardian of the Constitution, protecting individual rights and ensuring that all legislative and executive actions comports with constitutional principles.

The other responses touch on aspects related to judicial authority but do not encapsulate the essence of judicial review. For instance, while the ability of courts to review executive actions is related, it is a narrower concept than judicial review as a whole. Similarly, the process of reviewing judicial appointments pertains to the confirmation and evaluation of judges rather than the evaluation of laws against the Constitution. Lastly, the review of state laws by the federal government does highlight interactions between state and federal powers, but it does not capture the broader and more fundamental role of judicial review in assessing the constitutionality of legislative actions.
