At this point, the kindred topic of the obligation of contracts presented itself to the mind of Rufus King, suggested doubtless by a provision in the Ordinance then recently passed by Congress for the government of the Northwestern Territory.[303] The idea of a special restraint on legislative power, for the purpose of rendering inviolate the obligation of contracts, appears to have originated with Nathan Dane, the author of that Ordinance. It was not embraced in the resolve of 1784, reported by Mr. Jefferson, which contained the first scheme adopted by Congress for the establishment of new States in the Northwestern Territory; and it first appears in our national legislation in the Ordinance of 1787. Its transfer thence into the Constitution of the United States was a measure of obvious expediency, and indeed of clear necessity. In the Ordinance, Congress had provided a system of fundamental law, intended to be of perpetual obligation, for new communities, whose legislative power was to be moulded by certain original maxims of assumed justice and right. The opportunity thus afforded for shaping the limits of political sovereignty according to the requirements of a preconceived policy, enabled the framers of the Ordinance to introduce a limitation, which is not only peculiar to American constitutional law, but which, like many features of our institutions, grew out of previous abuses. In the old States of the Confederacy, from the time when they became self-governing communities, the power of a mere majority had been repeatedly exercised in legislation, without any regard to its effect on the civil rights and remedies of parties to existing contracts. The law of debtor and creditor was not only subjected to constant changes, but the nature of the change depended in many of the States upon the will of the debtor class, who formed the governing majority. So pressing were the evils thus engendered, that, when the framers of the Ordinance came to provide for the political existence of communities whose institutions they were to dictate, they determined to impose an effectual restraint on legislative power; and they accordingly provided, in terms much more stringent than were afterwards employed in the Constitution, that no law should have effect in the Territory which should in any manner whatever interfere with or affect private contracts or engagements previously made.[304]
