passed by those intended to be restrained." Marshall observed that the Constitution is "the fundamental and paramount law of the nation", and that it cannot be altered by an ordinary act of the legislature. Therefore, "an act of the Legislature repugnant to the Constitution is void." Marshall then discussed the role of the courts, which is at the heart of the doctrine of judicial review. It would be an "absurdity", said Marshall, to require the courts to apply a law that is void. Rather, it is the inherent duty of the courts to interpret and apply the Constitution, and to determine whether there is a conflict between a statute and the Constitution: Marshall stated that the courts are authorized by the provisions of the Constitution itself to "look into" the Constitution, that is, to interpret and apply it, and that they have the duty to refuse to enforce any laws that are contrary to the Constitution. Specifically, Article III provides that the federal judicial power "is extended to all cases arising under the Constitution." Article VI requires judges to take an oath "to support this Constitution." Article VI also states that only laws "made in pursuance of the Constitution" are the law of the land. Marshall concluded: "Thus, the particular phraseology of the Constitution of the United States confirms and strengthens the principle, supposed to be essential to all written Constitutions, that a law repugnant to the Constitution is void, and that courts, as well as other departments, are bound by that instrument." Marbury long has been regarded as the seminal case with respect to the doctrine of judicial review. Some scholars have suggested that Marshall's opinion in Marbury essentially created judicial review. In his book The Least Dangerous Branch, Professor Alexander Bickel wrote: Other scholars view this as an overstatement, and argue that Marbury was decided in a context in which judicial review already was a familiar concept. These scholars point to the facts showing that judicial review was acknowledged by the Constitution's framers, was explained in the Federalist Papers and in the ratification debates, and was used by both state and federal courts for more than twenty years before Marbury, including the Supreme Court in Hylton v. United States. One scholar concluded: "[B]efore Marbury, judicial review had gained wide support." Judicial review after Marbury Marbury was the point at which the Supreme Court adopted a monitoring role over
