Although the federal government can, in no possible view, be considered as a party to a compact made anterior to its existence, and by which it was, in fact, created; yet as the creature of that compact, it must be bound by it, to its creators, the several states in the union, and the citizens thereof. Having no existence but under the constitution, nor any rights, but such as that instrument confers; and those very rights being in fact duties; it can possess no legitimate power, but such, as is absolutely necessary for the performance of a duty, prescribed and enjoined by the constitution. Its duties, then, become the exact measure of its powers; and wherever it exerts a power for any other purpose, than the performance of a duty prescribed by the constitution, it transgresses its proper limits, and violates the public trust. Its duties, being moreover imposed for the general benefit and security of the several states, in their politic character; and of the people, both in their sovereign, and individual capacity, if these objects be not obtained, the government will not answer the end of its creation: it is therefore bound to the several states, respectively, and to every citizen thereof, for the due execution of those duties. And the observance of this obligation is enforced, by the solemn sanction of an oath, from all who administer the government.
The constitution of the United States, then being that instrument by which the federal government hath been created; its powers defined, and limited; and the duties, and functions of its several departments prescribed; the government, thus established, may be pronounced to be a confederate republic, composed of several independent, and sovereign democratic states, united for their common defense, and security against foreign nations, and for the purposes of harmony, and mutual intercourse between each other; each state retaining an entire liberty of exercising, as it thinks proper, all those parts of its sovereignty, which are not mentioned in the constitution, or act of union, as parts that ought to be exercised in common. It is the supreme law of the land 32, and as such binding upon the federal government; the several states; and finally upon all the citizens of the United States.... It can not be controlled, or altered without the express consent of the body politic of three fourths of the states in the union, or, of the people, of an equal number of the states. To prevent the necessity of an immediate appeal to the latter, a method is pointed out, by which amendments may be proposed and ratified by the concurrent act of two thirds of both houses of congress, and three fourths of the state legislatures: but if congress should neglect to propose amendments in this way, when they may be deemed necessary, the concurrent sense of two thirds of the state legislatures may enforce congress to call a convention, the amendments proposed by which, when ratified by the conventions of three fourths of the states, become valid, as a part of the constitution. In either mode, the assent of the body politic of the states, is necessary, either to complete, or to originate the measure.
Their submission to it’s operation is voluntary: it’s councils, it’s engagements, it’s authority are theirs, modified, and united. It’s sovereignty is an emanation from theirs, not a flame by which they have been consumed, nor a vortex in which they are swallowed up. Each is still a perfect state, still sovereign, still independent, and still capable, should the occasion require, to resume the exercise of it’s functions, as such, in the most unlimited extent.
