What principle allows courts to review and strike down laws that conflict with the Constitution?

• A. Judicial Review
• B. Due Process
• C. Habeas Corpus
• D. Double Jeopardy

Answer: (A)

Judicial review is the power of courts to interpret the Constitution and strike down laws or government actions that conflict with it. This authority creates a check on both the legislative and executive branches, ensuring that statutes remain within constitutional boundaries. The principle was firmly established in Marbury v. Madison, which held that courts can nullify laws that violate the Constitution.

That makes it the best answer because the question asks about reviewing and striking down laws on constitutional grounds. Due process concerns fair treatment within legal procedures; habeas corpus protects against unlawful detention; double jeopardy guards against being tried twice for the same offense. While important, those concepts do not describe the overarching power to review and invalidate laws that conflict with the Constitution.
