That the doctrine is applicable to the case of a contested power between the States and the General Government, we have the authority, not only of reason and analogy, but of the distinguished statesman already referred to. Mr. Jefferson, at a late period of his life, after long experience and mature reflection, says, “With respect to our State and Federal Governments, I do not think their relations are correctly understood by foreigners. They suppose the former are subordinate to the latter. This is not the case. They are co-ordinate departments of one simple and integral whole. But you may ask, If the two departments should claim each the same subject of power, where is the umpire to decide between them? In cases of little urgency or importance, the prudence of both parties will keep them aloof from the questionable ground; but, if it can neither be avoided nor compromised, a convention of the States must be called to ascribe the doubtful power to that department which they may think best.”
It is thus that our Constitution, by authorizing amendments, and by prescribing the authority and mode of making them, has, by a simple contrivance, with its characteristic wisdom, provided a power which, in the last resort, supersedes effectually the necessity, and even the pretext for force: a power to which none can fairly object; with which the interests of all are safe; which can definitively close all controversies in the only effectual mode, by freeing the compact of every defect and uncertainty, by an amendment of the instrument itself. It is impossible for human wisdom, in a system like ours, to devise another mode which shall be safe and effectual, and, at the same time, consistent with what are the relations and acknowledged powers of the two great departments of our Government. It gives a beauty and security peculiar to our system, which, if duly appreciated, will transmit its blessings to the remotest generations; but, if not, our splendid anticipations of the future will prove but an empty dream. Stripped of all its covering, the naked question is, whether ours is a federal or a consolidated government; a constitutional or absolute one; a government resting ultimately on the solid basis of the sovereignty of the States, or on the unrestrained will of a majority; a form of government, as in all other unlimited ones, in which injustice, and violence, and force must finally prevail. Let it never be forgotten that, where the majority rules, the minority is the subject; and that, if we should absurdly attribute to the former, the exclusive right of construing the Constitution, there would be, in fact, between the sovereign and subject, under such a government, no Constitution; or, at least, nothing deserving the name, or serving the legitimate object of so sacred an instrument.
How the States are to exercise this high power of interposition, which constitutes so essential a portion of their reserved rights that it cannot be delegated without an entire surrender of their sovereignty, and converting our system from a federal into a consolidated Government, is a question that the States only are competent to determine. The arguments which prove that they possess the power, equally prove that they are, in the language of Jefferson, “the rightful judges of the mode and measure of redress.” But the spirit of forbearance, as well as the nature of the right itself, forbids a recourse to it, except in cases of dangerous infractions of the Constitution; and then only in the last resort, when all reasonable hope of relief from the ordinary action of the Government has failed; when, if the right to interpose did not exist, the alternative would be submission and oppression on one side, or resistance by force on the other. That our system should afford, in such extreme cases, an intermediate point between these dire alternatives, by which the Government may be brought to a pause, and thereby an interval obtained to compromise differences, or, if impracticable, be compelled to submit the question to a constitutional adjustment, through an appeal to the States themselves, is an evidence of its high wisdom: an element not, as is supposed by some, of weakness, but of strength; not of anarchy or revolution, but of peace and safety. Its general recognition would of itself, in a great measure, if not altogether, supersede the necessity of its exercise, by impressing on the movements of the Government that moderation and justice so essential to harmony and peace, in a country of such vast extent and diversity of interests as ours; and would, if controversy should come, turn the resentment of the aggrieved from the system to those who had abused its powers (a point all-important), and cause them to seek redress, not in revolution or overthrow, but in reformation. It is, in fact, properly understood, a substitute—where the alternative would be force—tending to prevent, and, if that fails, to correct peaceably the aberrations to which all political systems are liable, and which, if permitted to accumulate without correction, must finally end in a general catastrophe.
