JUDICIAL REVIEW
In a constitutional law context, judicial review expresses the concept first articulated in Marbury v Madison, 5 US (1 Cranch) 137 (1803) that it is "the province and the duty of the judicial department to say what the law is." Under this doctrine the US Supreme Court and the highest courts of every state have assumed the power and responsibility to decide the constitutionality of the acts of the legislative and executive branches of their respective jurisdictions.
