Marbury v. Madison was the first time the Supreme Court declared something "unconstitutional," and established the concept of judicial review in the U.S. (the idea that courts may oversee and nullify the actions of another branch of government). The landmark decision helped define the "checks and balances" of the American form of government. No such power was explicitly granted to the judiciary in the constitution.
