Judicial review, the power of the judiciary to review the acts of other branches of government, was established for the national government in Marbury v. Madison in 1803.
Step-by-step explanation:
Judicial review, the power of the judiciary to review the acts of other branches of government, was established for the national government in Marbury v. Madison in 1803. The Supreme Court declared for itself the power of judicial review, allowing it to declare acts of the other branches unconstitutional. This power of the courts to overturn laws or other actions based on their constitutionality is a core aspect of the court's ability to check the other branches of government.
