Q. Judicial Review is the most distinctive contribution of which of the following Supreme Courts?
Answer: Supreme Court of the United States
Notes: The correct answer is the Supreme Court of the United States. Judicial review, the power to invalidate laws and executive actions that are contrary to the Constitution, was established in the landmark case Marbury v. Madison (1803). This principle has since become a cornerstone of American constitutional law, allowing the judiciary to act as a check on legislative and executive powers. Other countries, like Canada and India, have adopted similar practices, but the U.S. Supreme Court is credited with formalizing the concept.
