The first amounts merely to a declaration that the compact ought to have the interpretation plainly intended by the parties to it; the other, to a declaration that it ought to have the execution and effect intended by them. If the powers granted be valid, it is solely because they are granted; and if the granted powers are valid because granted, all other powers not granted must not be valid.
The resolution, having taken this view of the federal compact, proceeds to infer, "That, in case of a deliberate, palpable, and dangerous exercise of other powers, not granted by the said compact, the states, who are parties thereto, have the right, and are in duty bound, to interpose for arresting the progress of the evil, and for maintaining, within their respective limits, the authorities, rights, and liberties, appertaining to them."
It appears to your committee to be a plain principle, founded in common sense, illustrated by common practice, and essential to the nature of compacts, that, where resort can be had to no tribunal superior to the authority of the parties, the parties themselves must be the rightful judges, in the last resort, whether the bargain made has been pursued or violated. The Constitution of the United States was formed by the sanction of the states, given by each in its sovereign capacity. It adds to the stability and dignity, as well as to the authority, of the Constitution, that it rests on this legitimate and solid foundation. The states, then, being the parties to the constitutional compact, and in their sovereign capacity, it follows of necessity that there can be no tribunal, above their authority, to decide, in the last resort, whether the compact made by them be violated; and consequently, that, as the parties to it, they must themselves decide, in the last resort, such questions as may be of sufficient magnitude to require their interposition.
It does not follow, however, because the states, as sovereign parties to their constitutional compact, must ultimately decide whether it has been violated, that such a decision ought to be interposed either in a hasty manner or on doubtful and inferior occasions. Even in the case of ordinary conventions between different nations, where, by the strict rule of interpretation, a breach of a part may be deemed a breach of the whole,—every part being deemed a condition of every other part, and of the whole,—it is always laid down that the breach must be both wilful and material, to justify an application of the rule. But in the case of an intimate and constitutional union, like that of the United States, it is evident that the interposition of the parties, in their sovereign capacity, can be called for by occasions only deeply and essentially affecting the vital principles of their political system.
The resolution has, accordingly, guarded against any misapprehension of its object, by expressly requiring, for such an interposition, "the case of a deliberate, palpable, and dangerous breach of the Constitution, by the exercise of powers not granted by it." It must be a case not of a light and transient nature, but of a nature dangerous to the great purposes for which the Constitution was established. It must be a case, moreover, not obscure or doubtful in its construction, but plain and palpable. Lastly, it must be a case not resulting from a partial consideration or hasty determination, but a case stamped with a final consideration and deliberate adherence. It is not necessary, because the resolution does not require, that the question should be discussed, how far the exercise of any particular power, ungranted by the Constitution, would justify the interposition of the parties to it. As cases might easily be stated, which none would
