Wherever the real power in a Government lies, there is the danger of oppression. In our Governments the real power lies in the majority of the Community, and the invasion of private rights is chiefly to be apprehended, not from acts of Government contrary to the sense of its constituents, but from acts in which the Government is the mere instrument of the major number of the constituents.

Mr. MADISON observed that whatever reason might have existed for the equality of suffrage when the Union was a federal one among sovereign States, it must cease when a national Govermt. should be put into the place. In the former case, the acts of Congs. depended so much for their efficacy on the cooperation of the States, that these had a weight both within & without Congress, nearly in proportion to their extent and importance. In the latter case, as the acts of the Genl. Govt. would take effect without the intervention of the State legislatures, a vote from a small State wd. have the same efficacy & importance as a vote from a large one, and there was the same reason for different numbers of representatives from different States, as from Counties of different extents within particular States.

But it is understood that the nullifying doctrine imports that the decision of the State is to be presumed valid, and that it overrules the law of the United States, unless overruled by three fourths of the States.Can more be necessary to demonstrate the inadmissibility of such a doctrine, than that it puts it in the power of the smallest fraction over one fourth of the United States, that is, of seven states out of twenty four, to give the law, and even the Constitution to seventeen States; each of the seventeen having as parties to the Constitution, an equal right with each of the seven, to expound it, and to insist on the exposition. That the seven might, in particular instances be right, and the seventeen wrong, is more than possible. But to establish a positive and permanent rule giving such a power, to such a minority, over such a majority, would overturn the first principle of free government, and in practice necessarily overturn the government itself.It is to be recollected that the Constitution was proposed to the people of the States as a whole, and unanimously adopted by the States as a whole, it being a part of the Constitution that not less than three fourths of the States should be competent to make any alteration in what had been unanimously agreed to.
