The Constitution did not specifically delegate the power of judicial review to any one branch, and the executive and legislative branches might have argued in 1803 that they were equally entitled as the judicial branch to be entrusted with the power of judicial review. The Supreme Court ruled unanimously. Chief Justice John Marshall wrote these famous words that are now engraved on the wall of the Supreme Court building: "It is emphatically the province and duty of the judicial department to say what the law is."
