[Poole et al. v. The Lessee of Fleeger et al.] the first clause of the section, and cannot be validated by any consent of congress. As the compact between Kentucky and Tennessee does not come within this prohibition, and is one merely of boundary between the two states, the subject matter is not within the jurisdiction of congress, any farther than that it is subject to its consent, which, once given, the constitution is functus officio in relation to its controlling power over its terms or validity. The effect of such consent is, that thenceforth the compact has the same force as if it had been made between states who are not confederated, or between the United States and a foreign state, by a treaty of boundary: or as if there had been no restraining provision in the constitution. Its validity does not depend on any recognition or admission in or by the constitution, that states may make such compacts with the consent of con gress; the power existed in the states, in the plenitude of their sove 66 reignty, by original inherent right; they imposed a single restraint upon it, but did not make any surrender of their right, or consent to impair it to any greater extent. Like all other powers not granted to the United States, or prohibited to the states by the constitution, it is reserved to them, subject only to such restraints as it imposes, leaving its exercise free and unlimited in all other respects, without any auxiliary by any implied recognition or admission of the existence of the general power, consequent upon the particular limitation. Herein consists the peculiarity of my reasons for affirming the judgment of the circuit court in this case; fully concurring with the opinion delivered, as to the original power of the states to make compacts of boundary, as well as to the effect of the prohibition, being ‘a single limitation or restriction" upon the power. Vide 11 Pet. 209. I can give it no other effect by implication, without impairing the great principle on which the reserved powers of the states rest. Though the result, in this case, would be the same, whether the right of making compacts of boundary is original in the states, or exists by the admissions of the constitution, it might have an important bearing on other questions and cases, depending on the same general principle, as to the granting and restraining power which established that instrument. If it is considered as the source of the powers which are reserved to the states, it necessarily admits that its origin is from a power paramount to theirs, and limits them to the exercise of such as it recognises or tacitly admits, by imposing limited restraints. This is a principle which, once conceded, will destroy all harmony between the state and federal governments, by resorting to implication and construction to ascertain their respective powers, instead of adopting the definite rule furnished by the tenth amendment. That refers to the constitution for the ascertainment of the specific powers granted to the United States, or prohibited to the states, as the certain and fixed standard by which to measure them; and then, by express declaration, reserves all other powers to the states, or the peo [Poole et al. v. The Lessee of Fleeger et al.] ple thereof. The grant in the one case, or the prohibition in the other, must therefore be shown, or the given power remains with the state, in its original plenitude, not only independent of any power of the constitution, but paramount to it, as a portion of sovereignty attached to the soil and territory, in its original integrity. By adhering to this rule, there is found a marked line of separation between the powers of the two governments, the metes and bounds of which are visible; so that the portion of power separated from the state by its cession, can be as easily defined as its cession of a portion of its territory by known boundaries, a reference to which will bring every constitutional question to an unerring test. I have therefore considered those which have arisen in this case, as involving a general principle applicable to all restrictions on states. Though a narrower view would suffice to settle the questions presented upon this compact, or any compact between the states of this Union: yet, when we consider that the power of a state to make an agreement or compact, with a foreign power, is put on the same footing as one between two or more states, the necessity of an adherence to principle is the more apparent. It is a settled principle of this Court, that the boundaries of the United States, as fixed by the treaty of peace in 1783, were the boundaries of the several states, 12 Wh. 524; from which it follows, that on a contest between a state and a foreign power respecting the boundary between them, the state has the same power over the subject matter, as if the contest was with another state. It must then be ascertained, what is the source of that power, its extent by original right, how far it is restricted by the constitution; and when a compact of boundary is made with the consent of congress, whether their legislative power can be exercised over it to any extent. When this is done, it must then be inquired, how far the judicial power has been extended over such compacts by the constitution, and in controversies arising under them, what are judicial questions on which courts can act, as distinguished from political questions, which must be referred to the parties to the compact. In this view of the subject, I am disposed to take broader ground than is done in the opinion of the Court, and think it necessary to examine whether the powers of a state depend in any degree on the recognition or admission in the constitution, as the construction put upon it by those who framed or adopted it. This is a sound principle, when applied to grants of power by paramount authority, to a body subordinate to it, which can act only under the authority of the grant; and fairly applies to the powers of the federal government, which is a mere creature of the constitution. Such is the established rule of this Court, where there is an express exception of a particular case, in which any given power shall not be exercised, that it may be exercised in cases not within the exception; otherwise the exception would be useless, and the words of the constitution become unmeaning. [Poole et al. v. The Lessee of Fleeger et al.] 66 But the principle is radically different, when it is applied to a provision of the constitution, excepting a particular case from the exercise of state legislation, or containing a prohibition that a state law shall not be passed on any given subject, or shall not have the effect of doing what is prohibited; in such cases, there results no implication of power in other cases, for a most obvious reason:- -That states do not derive their powers from the constitution, but by their own inherent reserved right can act on all subjects which have not been delegated to the federal government, or prohibited to states. This distinction necessarily arises from the whole language of the constitution and amendments, and is expressly recognised in the most solemn adjudications of this Court. "The government, then, of the United States, can claim no powers which are not granted to it by the constitution; and the powers, actually granted, must be such as are expressly given, or given by necessary implication;" 1 Wh. 326; Hunter v. Martin. The powers retained by the states, proceed from the people of the several states, and remain, after the adoption of the constitution, what they were before, except so far as they may be abridged by that instrument;" 4 Wh. 193. So where there is an exception to the exercise of the power of congress, as in the first clause of the ninth section of the first article of the constitution. "The migration or importation of such persons as any of the states, now existing, shall think proper to admit, shall not be prohibited by congress prior to the year 1808. The whole object of the exception is to preserve the power to those states which might be disposed to exercise it, and its language seems to convey this idea to the Court unequivocally. It is an exception to the power to regulate commerce, and manifests, clearly, the intention to continue the pre-existing right of the state to admit or exclude for a limited period;" 9 Wh. 206, 7, 216. So when a state is prohibited from imposing duties on imports, except what may be absolutely necessary for executing its inspection laws. "This tax is an exception to the prohibition on the states to lay duties on imports and exports. The exception was made, because the tax would otherwise have been within the prohibition;" 12 Wh. 436. "If it be a rule of interpretation to which all assent, that the exception of a particular thing, from general words, proves, that in the opinion of the lawgiver, the thing excepted would be within the general clause, had the exception not been made, we know no reason why this general rule should not be as applicable to the constitution as other instruments;" 12 Wh. 438. In applying this rule to deeds, the language of this Court is strong and clear. "It is observable that the granting part of this deed begins by excepting, from its operation, all the lots, &c., which are within the exception. The words are, doth grant, &c., except as is hereinafter excepted, all those hereafter mentioned and described lots, &c. In order, therefore, to ascertain what is granted, we must first ascertain what is within the exception; for whatever [Poole et al. v. The Lessee of Fleeger et al.] is included in the exception, is excluded from the grant, according to the maxim laid down in Co. Litt. 47, a. Si quis rem dat et portem retinet illa pars quam retinet semper cum eo est et semper fuit;" 6 Pet. 310. In a subsequent case, at the same term, the same rule and maxim was adopted, and applied to a treaty with a foreign nation. "It became, then, all-important to ascertain what was granted, by what was excepted. The king of Spain was the grantor, the treaty was his deed, the exception was made by him, and its nature and effect depended on his intention, expressed by his words, in reference to the thing granted, and the thing reserved and excepted, in and by the grant;" 6 Pet. 741. As this was a treaty of cession, granting soil and sovereignty, it is, in the latter respect, precisely analogous to the grant of power, by the constitution, to the federal government; so that its exceptions, prohibitions, and reservations, as well as grants, must be interpreted as all other instruments, grants, treaties, and cessions, taking the words as the words of the grantor, referred to the subject matter granted or excepted, &c. Assuming, on the reasons and authority referred to in the preceding general views, that the constitution is a grant made by the people of the several states, by their separate ratifications, and that the prohibition on their pre-existing powers are their separate voluntary covenants, restraining the exercise of those which are reserved, over the subjects prohibited, these conclusions necessarily follow:That a prohibition upon a state, as to any given subject, can, by no just reasoning, enlarge or vary the powers delegated to congress, so as to bring, within its jurisdiction, any matters not within the enumerations of the powers granted. That where the assent of congress is made necessary to validate any law of a state, congress can only assent or dissent thereto or therefrom, but can exercise no legislative power over the subject matter, without some express authority to revise and control such state law, by regulations of its own. And that in the absence of any power in congress, to do more than simply assent or dissent, the assent is a condition; and when once given to an act of a state, it has the same validity as if no prohibition had been made in the constitution against the exercise of any right of the state, to do the act in virtue of its reserved powers, or any condition in any way imposed, to affect its original inherent sovereignty. The assent of congress is made an exception to the prohibition, and when given, takes the case out of the prohibition, and leaves the power of the state uncontrolled, on the common law rule, that "an exception out of an exception leaves the thing unexcepted;" 4 D. C. D. 290. "No state shall, without the consent of congress, enter into any agreement or compact with another state, or a foreign power." By the terms, then, of this clause, whenever the consent of congress is given to any such agreement or compact, the prohibition is fully satisfied and ceases to operate; the states stand towards each [Poole et al. v. The Lessee of Fleeger et al.] other, and foreign powers, as they did before the adoption of the constitution, so far as this sentence abridged their reserved powers. But as the consent of congress cannot dispense with the prohibition in the first sentence of this section, it becomes, by necessary implication, a proviso or limitation to the second. That such agreement or compact shall not be a treaty, alliance, or confederation; if it does not come within the constitutional meaning of these terms, the agreement or compact is valid, if made with the consent of congress; if it does, it is void by the first part of the prohibition, which annuls whatever is done in opposition to it. A reference to the articles of confederation will show the sense in which these terms are used in the constitution, in their bearing on this case. Article 6. "No state, without the consent of the United States, in congress assembled, shall send any embassy to, or receive any embassy from, or enter into any conference, agreement, alliance, or treaty, with, any king, prince, or state. No two or more states shall enter into any treaty, confederation, or alliance whatever, between them, without the consent of the United States in congress assembled, specifying accurately the purposes for which the same is to be entered into, and how long it shall continue;" 1 Vol. Laws, 15. Article 9. "The United States, in congress assembled, shall have the sole and exclusive right and power of sending and receiving ambassadors, entering into treaties and alliances," &c. "The United States," &c. " shall also be the last resort on appeal, in all disputes and differences, now subsisting, or that may hereafter arise, between two or more states, concerning boundary, jurisdiction, or any cause whatever, which authority shall always be exercised in the manner following," &c., 1 Vol. 16. "All controversies respecting the private right of soil, claimed under different grants of two or more states, whose jurisdiction as they may respect such lands, and the states which passed such grants, are adjusted, the said grants or either of them being, at the same time, claimed to have originated antecedent to such settlement of jurisdiction, shall, on petition of either party to the congress of the United States, be finally determined as near as may be, in the same manner as is before prescribed for deciding disputes respecting territorial jurisdiction between different states;" i Laws, 17. From these provisions it is most manifest, that the framers of the constitution had the whole subject matter directly before them, and substituted the prohibitions in the tenth section of the first article, for those in the sixth article of confederation, with two important changes. 1. In the discrimination between the prohibition on states, in relation to foreign powers, and between themselves, apparent in the two first sentences of the sixth article of confederation. All embassies to or from, and all conferences or agreements with foreign powers, are |
