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 sys

tem 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 inquire 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 propor

tioned 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 government, 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.

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 ur 'imited 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 consquently 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 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 favor 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?

This is too extravagant to be maintained.

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 obey?

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
