APPEAL from the Court for the Trial of Impeachments and Correction of Errors of the State of New-York. Aaron Ogden filed his bill in the Court of Chancery of that State, against Thomas Gibbons, setting forth the several acts of the Legislature thereof, enacted for the purpose of securing to Robert R. Livingston and Robert Fulton, the exclusive navigation of all the waters within the jurisdiction of that State, with boats moved by fire or steam, for a term of years which has not yet expired; and authorizing the Chancellor to award an injunction, restraining any person whatever from navigating those waters with boats of that description. The bill stated an assignment from Livingston and Fulton to one John R. Livingston, and from him to the complainant, Ogden, of the right to navigate the waters between Elizabethtown, and other places in New-Jersey, and the city of New-York; and that Gibbons, the defendant below, was in possession of two steam boats, called the Stoudinger and the Bellona, which were actually employed in running between New-York and Elizabethtown, in violation of the exclusive privilege conferred on the complainant, and praying an injunction to restrain the said Gibbons from using the said boats, or any other propelled by fire or steam, in navigating the waters within the territory of New-York. The injunction having been awarded, the answer of Gibbons was filed; in which he stated, that the boats employed by him were duly enrolled and licensed, to be employed in carrying on the coasting trade, under the act of Congress, passed the 18th of February, 1793, entitled, 'An act for enrolling and licensing ships and vessels to be employed in the coasting trade and fisheries, and for regulating the same.' And the defendant insisted on his right, in virtue of such licenses, to navigate the waters between Elizabethtown and the city of New-York, the said acts of the Legislature of the State of New-York to the contrary notwithstanding. At the hearing, the Chancellor perpetuated the injunction, being of the opinion, that the said acts were not repugnant to the constitution and laws of the United States, and were valid. This decree was affirmed in the Court for the Trial of Impeachments and Correction of Errors, which is the highest Court of law and equity in the State, before which the cause could be carried, and it was thereupon brought to this Court by appeal....
Mr. Chief Justice MARSHALL delivered the opinion of the Court, and, after stating the case, proceeded as follows:
The appellant contends that this decree is erroneous, because the laws which purport to give the exclusive privilege it sustains, are repugnant to the constitution and laws of the United States.
They are said to be repugnant--
1st. To that clause in the constitution which authorizes Congress to regulate commerce.
2d. To that which authorizes Congress to promote the progress of science and useful arts.
This instrument contains an enumeration of powers expressly granted by the people to their government. It has been said, that these powers ought to be construed strictly. But why ought they to be so construed? Is there one sentence in the constitution which gives countenance to this rule? In the last of the enumerated powers, that which grants, expressly, the means for carrying all others into execution, Congress is authorized 'to make all laws which shall be necessary and proper' for the purpose. But this limitation on the means which may be used, is not extended to the powers which are conferred; nor is there one sentence in the constitution, which has been pointed out by the gentlemen of the bar, or which we have been able to discern, that prescribes this rule. We do not, therefore, think ourselves justified in adopting it.... As men, whose intentions require no concealment, generally employ the words which most directly and aptly express the ideas they intend to convey, the enlightened patriots who framed our constitution, and the people who adopted it, must be understood to have employed words in their natural sense, and to have intended what they have said....
The words are, 'Congress shall have power to regulate commerce with foreign nations, and among the several States, and with the Indian tribes.'
The subject to be regulated is commerce; and our constitution being, as was aptly said at the bar, one of enumeration, and not of definition, to ascertain the extent of the power, it becomes necessary to settle the meaning of the word. The counsel for the appellee would limit it to traffic, to buying and selling, or the interchange of commodities, and do not admit that it comprehends navigation. This would restrict a general term, applicable to many objects, to one of its significations. Commerce, undoubtedly, is traffic, but it is something more: it is intercourse. It describes the commercial intercourse between nations, and parts of nations, in all its branches, and is regulated by prescribing rules for carrying on that intercourse. The mind can scarcely conceive a system for regulating commerce between nations, which shall exclude all laws concerning navigation, which shall be silent on the admission of the vessels of the one nation into the ports of the other, and be confined to prescribing rules for the conduct of individuals, in the actual employment of buying and selling, or of barter....
The subject to which the power is next applied, is to commerce 'among the several States.' The word 'among' means intermingled with. A thing which is among others, is intermingled with them. Commerce among the States, cannot stop at the external boundary line of each State, but may be introduced into the interior.
It is not intended to say that these words comprehend that commerce, which is completely internal, which is carried on between man and man in a State, or between different parts of the same State, and which does not extend to or affect other States. Such a power would be inconvenient, and is certainly unnecessary.
Comprehensive as the word 'among' is, it may very properly be restricted to that commerce which concerns more States than one. The phrase is not one which would probably have been selected to indicate the completely interior traffic of a State, because it is not an apt phrase for that purpose; and the enumeration of the particular classes of commerce, to which the power was to be extended, would not have been made, had the intention been to extend the power to every description.... The genius and character of the whole government seem to be, that its action is to be applied to all the external concerns of the nation, and to those internal concerns which affect the States generally; but not to those which are completely within a particular State, which do not affect other States, and with which it is not necessary to interfere, for the purpose of executing some of the general powers of the government. The completely internal commerce of a State, then, may be considered as reserved for the State itself.
We are now arrived at the inquiry-What is this power?
It is the power to regulate; that is, to prescribe the rule by which commerce is to be governed. This power, like all others vested in Congress, is complete in itself, may be exercised to its utmost extent, and acknowledges no limitations, other than are prescribed in the constitution.... The power of Congress, then, comprehends navigation, within the limits of every State in the Union; so far as that navigation may be, in any manner, connected with 'commerce with foreign nations, or among the several States, or with the Indian tribes.' It may, of consequence, pass the jurisdictional line of New-York, and act upon the very waters to which the prohibition now under consideration applies....
In argument, it has been contended, that if a law passed by a State, in the exercise of its acknowledged sovereignty, comes into conflict with a law passed by Congress in pursuance of the constitution, they affect the subject, and each other, like equal opposing powers. But the framers of our constitution foresaw this state of things, and provided for it, by declaring the supremacy not only of itself, but of the laws made in pursuance of it. The nullity of any act, law. The appropriate inconsistent with the constitution, is produced by the declaration, that the constitution is the supreme law. The appropriate application of that part of the clause which confers the same supremacy on laws and treaties, is to such acts of the State Legislatures as do not transcend their powers, but, though enacted in the execution of acknowledged State powers, interfere with, or are contrary to the laws of Congress, made in pursuance of the constitution, or some treaty made under the authority of the United States. In every such case, the act of Congress, or the treaty, is supreme; and the law of the State, though enacted in the exercise of powers not controverted, must yield to it....
This act demonstrates the opinion of Congress, that steam boats may be enrolled and licensed, in common with vessels using sails. They are, of course, entitled to the same privileges, and can no more be restrained from navigating waters, and entering ports which are free to such vessels, than if they were wafted on their voyage by the winds, instead of being propelled by the agency of fire. The one element may be as legitimately used as the other, for every commercial purpose authorized by the laws of the Union; and the act of a State inhibiting the use of either to any vessel having a license under the act of Congress, comes, we think, in direct collision with that act.
As this decides the cause, it is unnecessary to enter in an examination of that part of the constitution which empowers Congress to promote the progress of science and the useful arts....
Powerful and ingenious minds, taking, as postulates, that the powers expressly granted to the government of the Union, are to be contracted by construction, into the narrowest possible compass, and that the original powers of the States are retained, if any possible construction will retain them, may, by a course of well digested, but refined and metaphysical reasoning, founded on these premises, explain away the constitution of our country, and leave it, a magnificent structure, indeed, to look at, but totally unfit for use. They may so entangle and perplex the understanding, as to obscure principles, which were before thought quite plain, and induce doubts where, if the mind were to pursue its own course, none would be perceived. In such a case, it is peculiarly necessary to recur to safe and fundamental principles to sustain those principles, and when sustained, to make them the tests of the arguments to be examined.
