Answer: The Supreme Court case Malbury v. Madison was significant because it established the power of judicial review.
Step-by-step explanation: Malbury v. Madison was a U.S Supreme Court case that was argued and decided in 1803. This was a landmark case because it established the principle of judicial review, which is based on a court's power to invalidate laws and acts for going against what has been established in the Constitution, that is to say for being unlawful. The decision of the Supreme Court in the Malbury v. Madison case was considering Section 13 of the Judiciary Act of 1789 unconstitutional.
