What legal principle gave marbury a right to same remedy under law?

The legal principle that gave William Marbury a right to the same remedy under the law is rooted in the concept of judicial review established by the Supreme Court in Marbury v. Madison (1803). The Court determined that Marbury was entitled to his commission as it was a legal right, and that it was the duty of the judiciary to provide a remedy when a right is violated. This case established that it is the role of the courts to interpret the law and ensure that individuals receive the remedies they are entitled to under it.
