1803
Chief Justice Marshall delivered the opinion of the Court.

In the order in which the court has viewed this subject, the following questions have been considered and decided: 1st. Has the applicant a right to the commission he demands? 2d. If he has a right, and that right has been violated, do the laws of his country afford him a remedy? 3d. If they do afford him a remedy, is it a mandamus issuing from this court?

The first object of inquiry is -- 1st. Has the applicant a right to the commission he demands? . . . It [is] decidedly the opinion of the court, that when a commission has been signed by the president, the appointment is made; and that the commission is complete, when the seal of the United States has been affixed to it by the secretary of state. . . . To withhold his commission, therefore, is an act deemed by the court not warranted by law, but violative of a vested legal right. This brings us to the second inquiry; which is 2dly. If he has a right, and that right has been violated, do the laws of his country afford him a remedy? The very essence of civil liberty certainly consists in the right of every individual to claim the protection of the laws, whenever he receives an injury. One of the first duties of government is to afford that protection. [The] government of the United States has been emphatically termed a government of laws, and not of men. It will certainly cease to deserve this high appellation, if the laws furnish no remedy for the violation of a vested legal right. . . . By the constitution of the United States, the President is invested with certain important political powers, in the exercise of which he is to use his own discretion, and is accountable only to his country in his political character, and to his own conscience. To aid him in the performance of these duties, he is authorized to appoint certain officers, who act by his authority and in conformity with his orders. In such cases, their acts are his acts; and whatever opinion may be entertained of the manner in which executive discretion may be used, still there exists, and can exist, no power to control that discretion. The subjects are political. They respect the nation, not individual rights, and being entrusted to the executive, the decision of the executive is conclusive. . . . But when the legislature proceeds to impose on that officer other duties; when he is directed peremptorily to perform certain acts; when the rights of individuals are dependent on the performance of those acts; he is so far the officer of the law; is amenable to the laws for his conduct; and cannot at his discretion sport away the vested rights of others. The conclusion from this reasoning is, that where the heads of departments are the political or confidential agents of the executive, merely to execute the will of the President, or rather to act in cases in which the executive possesses a constitutional or legal discretion, nothing can be more perfectly clear than that their acts are only politically examinable. But where a specific duty is assigned by law, and individual rights depend upon the performance of that duty, it seems equally clear, that the individual who considers himself injured, has a right to resort to the laws of his country for a remedy. . . . It is, then, the opinion of the Court [that Marbury has a] right to the commission; a refusal to deliver which is a plain violation of that right, for which the laws of his country afford him a remedy.

It remains to be enquired whether, 3dly. He is entitled to the remedy for which he applies. This depends on -- 1st. The nature of the writ applied for, and, 2dly. The power of this court. 1st. The nature of the writ. . . . This, then, is a plain case for a mandamus, either to deliver the commission, or a copy of it from the record; and it only remains to be enquired, Whether it can issue from this court. The act to establish the judicial courts of the United States authorizes the Supreme Court "to issue writs of mandamus in cases warranted by the principles and usages of law, to any courts appointed, or persons holding office, under the authority of the United States." The Secretary of State, being a person holding an office under the authority of the United States, is precisely within the letter of the description; and if this court is not authorized to issue a writ of mandamus to such an officer, it must be because the law is unconstitutional, and therefore incapable of conferring the authority, and assigning the duties which its words purport to confer and assign. The constitution vests the whole judicial power of the United States in one Supreme Court, and such inferior courts as congress shall, from time to time, ordain and establish. This power is expressly extended to all cases arising under the laws of the United States; and, consequently, in some form, may be exercised over the present case; because the right claimed is given by a law of the United States.

In the distribution of this power it is declared that "the Supreme Court shall have original jurisdiction in all cases affecting ambassadors, other public ministers and consuls, and those in which a state shall be a party. In all other cases, the Supreme Court shall have appellate jurisdiction." It has been insisted, at the bar, that as the original grant of jurisdiction, to the supreme and inferior courts, is general, and the clause, assigning original jurisdiction to the Supreme Court, contains no negative or restrictive words, the power remains to the legislature, to assign original jurisdiction to that court in other cases than those specified in the article which has been recited; provided those cases belong to the judicial power of the United States. If it had been intended to leave it in the discretion of the legislature to apportion the judicial power between the supreme and inferior courts according to the will of that body, it would certainly have been useless to have proceeded further than to have defined the judicial power, and the tribunals in which it should be vested. The subsequent part of the section is mere surplusage, is entirely without meaning, if such is to be the construction. If congress remains at liberty to give this court appellate jurisdiction, where the constitution has declared their jurisdiction shall be original; and original jurisdiction where the constitution has declared it shall be appellate; the distribution of jurisdiction, made in the constitution, is form without substance. Affirmative words are often, in their operation, negative of other objects than those affirmed; and in this case, a negative or exclusive sense must be given to them or they have no operation at all. It cannot be presumed that any clause in the constitution is intended to be without effect; and, therefore, such a construction is inadmissible, unless the words require it. If the solicitude of the convention, respecting our peace with foreign powers, induced a provision that the supreme court should take original jurisdiction in cases which might be supposed to affect them; yet the clause would have proceeded no further than to provide for such cases, if no further restriction on the powers of congress had been intended. That they should have appellate jurisdiction in all other cases, with such exceptions as congress might make, is no restriction; unless the words be deemed exclusive of original jurisdiction. When an instrument organizing fundamentally a judicial system, divides it into one supreme, and so many inferior courts as the legislature may ordain and establish; then enumerates its powers, and proceeds so far to distribute them, as to define the jurisdiction of the supreme court by declaring the cases in which it shall take original jurisdiction, and that in others it shall take appellate jurisdiction; the plain import of the words seems to be, that in one class of cases its jurisdiction is original, and not appellate; in the other it is appellate, and not original. If any other construction would render the clause inoperative, that is an additional reason for rejecting such other construction, and for adhering to their obvious meaning. To enable this court, then, to issue a mandamus, it must be shown to be an exercise of appellate jurisdiction, or to be necessary to enable them to exercise appellate jurisdiction. It has been stated at the bar that the appellate jurisdiction may be exercised in a variety of forms, and that if it be the will of the legislature that a mandamus should be used for that purpose, that will must be obeyed. This is true, yet the jurisdiction must be appellate, not original. It is the essential criterion of appellate jurisdiction, that it revises and corrects the proceedings in a cause already instituted, and does not create that cause. Although, therefore, a mandamus may be directed to courts, yet to issue such a writ to an officer for the delivery of a paper, is in effect the same as to sustain an original action for that paper, and, therefore, seems not to belong to appellate, but to original jurisdiction. Neither is it necessary in such a case as this, to enable the court to exercise its appellate jurisdiction. The authority, therefore, given to the Supreme Court, by the act establishing the judicial courts of the United States, to issue writs of mandamus to public officers, appears not to be warranted by the constitution; and it becomes necessary to enquire whether a jurisdiction, so conferred, can be exercised. The question, whether an act, repugnant to the constitution, can become the law of the land, is a question deeply interesting to the United States; but happily, not of an intricacy proportioned to its interest. It seems only necessary to recognize certain principles, supposed to have been long and well established, to decide it. That the people have an original right to establish, for their future govern-ment, such principles as, in their opinion, shall most conduce to their own happiness, is the basis on which the whole American fabric has been erected. The exercise of this original right is a very great exertion; nor can it, nor ought it, to be frequently repeated. The principles, therefore, so established, are deemed fundamental. And as the authority from which they proceed is supreme, and can seldom act, they are designed to be permanent. This original and supreme will organizes the government, and assigns to different departments their respective powers. It may either stop here, or establish certain limits not to be transcended by those departments.

This is too extravagant to be maintained. The government of the United States is of the latter description. The powers of the legislature are defined and limited; and that those limits may not be mistaken, or forgotten, the constitution is written. To what purpose are powers limited, and to what purpose is that limitation committed to writing, if these limits may, at any time, be passed by those intended to be restrained? The distinction between a government with limited and unlimited powers is abolished, if those limits do not confine the persons on whom they are imposed, and if acts prohibited and acts allowed, are of equal obligation. It is a proposition too plain to be contested, that the constitution controls any legislative act repugnant to it; or, that the legislature may alter the constitution by an ordinary act. Between these alternatives there is no middle ground. The constitution is either a superior, paramount law, unchangeable by ordinary means, or it is on a level with ordinary legislative acts, and, like other acts, is alterable when the legislature shall please to alter it. If the former part of the alternative be true, then a legislative act contrary to the constitution is not law: if the latter part be true, then written constitutions are absurd attempts, on the part of the people, to limit a power in its own nature illimitable. Certainly all those who have framed written constitutions contemplate them as forming the fundamental and paramount law of the nation, and consequently, the theory of every such government must be, that an act of the legislature, repugnant to the constitution, is void. This theory is essentially attached to a written constitution, and is, consequently, to be considered, by this court, as one of the fundamental principles of our society. It is not therefore to be lost sight of in the further consideration of this subject. If an act of the legislature, repugnant to the constitution, is void, does it, notwithstanding its invalidity, bind the courts, and oblige them to give it effect? Or, in other words, though it be not law, does it constitute a rule as operative as if it was a law? This would be to overthrow in fact what was established in theory; and would seem, at first view, an absurdity too gross to be insisted on. It shall, however, receive a more attentive consideration. It is emphatically the province and duty of the judicial department to say what the law is. Those who apply the rule to particular cases, must of necessity expound and interpret that rule. If two laws conflict with each other, the courts must decide on the operation of each. So if a law be in opposition to the constitution; if both the law and the constitution apply to a particular case, so that the court must either decide that case conformably to the law, disregarding the constitution; or conformably to the constitution, disregarding the law; the court must determine which of these conflicting rules governs the case. This is of the very essence of judicial duty. If, then, the courts are to regard the constitution, and the constitution is superior to any ordinary act of the legislature, the constitution, and not such ordinary act, must govern the case to which they both apply. Those then who controvert the principle that the constitution is to be considered, in court, as a paramount law, are reduced to the necessity of maintaining that the courts must close their eyes on the constitution, and see only the law. This doctrine would subvert the very foundation of all written constitutions. It would declare that an act which, according to the principles and theory of our government, is entirely void, is yet, in practice, completely obligatory. It would declare that if the legislature shall do what is expressly forbidden, such act, notwithstanding the express prohibition, is in reality effectual. It would be giving to the legislature a practical and real omnipotence, with the same breath which professes to restrict their powers within narrow limits. It is prescribing limits, and declaring that those limits may be passed at pleasure. That it thus reduces to nothing what we have deemed the greatest improvement on political institutions -- a written constitution -- would of itself be sufficient, in America, where written constitutions have been viewed with so much reverence, for rejecting the construction. But the peculiar expressions of the constitution of the United States furnish additional arguments in favour of its rejection. The judicial power of the United States is extended to all cases arising under the constitution. Could it be the intention of those who gave this power, to say that in using it the constitution should not be looked into? That a case arising under the constitution should be decided without examining the instrument under which it arises?

In some cases, then, the constitution must be looked into by the judges. And if they can open it at all, what part of it are they forbidden to read or to oey? There are many other parts of the constitution which serve to illustrate this subject. It is declared that "no tax or duty shall be laid on articles exported from any state." Suppose a duty on the export of cotton, of tobacco, or of flour; and a suit instituted to recover it. Ought judgment to be rendered in such a case? Ought the judges to close their eyes on the constitution, and only see the law? The constitution declares that "no bill of attainder or ex post facto law shall be passed." If, however, such a bill should be passed, and a person should be prosecuted under it; must the court condemn to death those victims whom the constitution endeavors to preserve? "No person," says the constitution, "shall be convicted of treason unless on the testimony of two witnesses to the same overt act, or on confession in open court." Here the language of the constitution is addressed especially to the courts. It prescribes, directly for them, a rule of evidence not to be departed from. If the legislature should change that rule, and declare one witness, or a confession out of court, sufficient for conviction, must the constitutional principle yield to the legislative act? From these, and many other selections which might be made, it is apparent, that the framers of the constitution contemplated that instrument as a rule for the government of courts, as well as of the legislature. Why otherwise does it direct the judges to take an oath to support it? This oath certainly applies, in an especial manner, to their conduct in their official character. How immoral to impose it on them, if they were to be used as the instruments, and the knowing instruments, for violating what they swear to support! The oath of office, too, imposed by the legislature, is completely demonstrative of the legislative opinion on this subject. It is in these words: "I do solemnly swear that I will administer justice without respect to persons, and do equal right to the poor and to the rich; and that I will faithfully and impartially discharge all the duties incumbent on me as _____, according to the best of my abilities and understanding, agreeably to the constitution, and laws of the United States." Why does a Judge swear to discharge his duties agreeably the constitution of the United States, if that constitution forms no rule for his government? If it is closed upon him, and cannot be inspected by him?

If such be the real state of things, this is worse than solemn mockery. To prescribe, or to take this oath, becomes equally a crime. It is also not entirely unworthy of observation that in declaring what shall be the supreme law of the land, the constitution itself is first mentioned; and not the laws of the United States generally, but those only which shall be made in pursuance of the constitution, have that rank. 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. The rule must be discharged. Source: 1 Cranch 137 (1803).
