All this might have been done without going beyond the limits of their commission "to revise the Articles of Confederation," and to consider and report such "alterations and provisions" as might seem necessary to "render the Federal Constitution adequate to the exigencies of government and the preservation of the Union." A serious difficulty, however, was foreseen. The thirteenth and last of the aforesaid articles had this provision, which has already been referred to: "The Articles of this Confederation shall be inviolably observed by every State, and the union shall be perpetual; nor shall any alteration, at any time hereafter, be made in any of them, unless such alteration be agreed to in a Congress of the United States, and be afterward confirmed by the Legislatures of every State."

It is obvious, from an examination of the records, as has already been shown, that the original idea in calling a Convention was, that their recommendations should take the course prescribed by this article—first, a report to the Congress, and then, if approved by that body, a submission to the various Legislatures for final action. There was no reason to apprehend the non-concurrence of Congress, in which a mere majority would determine the question; but the consent of the Legislatures of "every State" was requisite in order to final ratification, and there was serious reason to fear that this consent could not be obtained. Rhode Island, as we have seen, had declined to send any representatives to the Convention; of the three delegates from New York, two had withdrawn; and other indications of dissatisfaction had appeared. In case of the failure of a single Legislature to ratify, the labors of the Convention would go for naught, under a strict adherence to the letter of the article above cited. The danger of a total frustration of their efforts was imminent.

In this emergency the Convention took the responsibility of transcending the limits of their instructions, and recommending a procedure which was in direct contravention of the letter of the Articles of Confederation. This was the introduction of a provision into the new Constitution, that the ratification of nine States should be sufficient for its establishment among themselves. In order to validate this provision, it was necessary to refer it to authority higher than that of Congress and the State Legislatures—that is, to the People of the States, assembled, by their representatives, in convention. Hence it was provided, by the seventh and last article of the new Constitution, that "the ratification of the Conventions of nine States" should suffice for its establishment "between the States so ratifying the same."

There was another reason, of a more general and perhaps more controlling character, for this reference to conventions for ratification, even if entire unanimity of the State Legislatures could have been expected. Under the American theory of republican government, conventions of the people, duly elected and accredited as such, are invested with the plenary power inherent in the people of an organized and independent community, assembled in mass. In other words, they represent and exercise what is properly the sovereignty of the people. State Legislatures, with restricted powers, do not possess or represent sovereignty. Still less does the Congress of a union or confederacy of States, which is by two degrees removed from the seat of sovereignty. We sometimes read or hear of "delegated sovereignty," "divided sovereignty," with other loose expressions of the same sort; but no such thing as a division or delegation of sovereignty is possible.

In order, therefore, to supersede the restraining article above cited and to give the highest validity to the compact for the delegation of important powers and functions of government to a common agent, an authority above that of the State Legislatures was necessary. Mr. Madison, in the "Federalist,"[33] says: "It has been heretofore noted among the defects of the Confederation, that in many of the States it had received no higher sanction than a mere legislative ratification." This objection would of course have applied with greater force to the proposed Constitution, which provided for additional grants of power from the States, and the conferring of larger and more varied powers upon a General Government, which was to act upon individuals instead of States, if the question of its confirmation had been submitted merely to the several State Legislatures. Hence the obvious propriety of referring it to the respective people of the States in their sovereign capacity, as provided in the final article of the Constitution.

In this article provision was deliberately made for the secession (if necessary) of a part of the States from a union which, when formed, had been declared "perpetual," and its terms and articles to be "inviolably observed by every State."

Opposition was made to the provision on this very ground—that it was virtually a dissolution of the Union, and that it would furnish a precedent for future secessions. Mr. Gerry, a distinguished member from Massachusetts—afterward Vice-President of the United States—said, "If nine out of thirteen (States) can dissolve the compact, six out of nine will be just as able to dissolve the future one hereafter."

Mr. Madison, who was one of the leading members of the Convention, advocating afterward, in the "Federalist," the adoption of the new Constitution, asks the question, "On what principle the Confederation, which stands in the solemn form of a compact among the States, can be superseded without the unanimous consent of the parties to it?" He answers this question "by recurring to the absolute necessity of the case; to the great principle of self-preservation; to the transcendent law of nature and of nature's God, which declares that the safety and happiness of society are the objects at which all political institutions aim, and to which all such institutions must be sacrificed." He proceeds, however, to give other grounds of justification:

"It is an established doctrine on the subject of treaties, that all the articles are mutually conditions of each other; that a breach of any one article is a breach of the whole treaty; and that a breach committed by either of the parties absolves the others, and authorizes them, if they please, to pronounce the compact violated and void. Should it unhappily be necessary to appeal to these delicate truths for a justification for dispensing with the consent of particular States to a dissolution of the Federal pact, will not the complaining parties find it a difficult task to answer the multiplied and important infractions with which they may be confronted? The time has been when it was incumbent on us all to veil the ideas which this paragraph exhibits. The scene is now changed, and with it the part which the same motives dictate."

Mr. Madison's idea of the propriety of veiling any statement of the right of secession until the occasion arises for its exercise, whether right or wrong in itself, is eminently suggestive as explanatory of the caution exhibited by other statesmen of that period, as well as himself, with regard to that "delicate truth."
