The general assembly of Virginia in 1798 adopted resolutions declaring that it viewed "the powers of the Federal government ... as limited by the plain sense and intention of [the Constitution] ... and that, in case of a deliberate, palpable, and dangerous exercise of other powers, not granted, ... the states ... 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 authority, rights, and liberties appertaining to them." These resolutions were drawn by Madison who had now come to oppose the strong centralizing policy of the Federalists.
A more explicit statement of this doctrine is to be found in the Kentucky Resolutions of 1798 which declared "that the several states composing the United States of America are not united on the principle of unlimited submission to their general government; ... and that whenever the general government assumes undelegated powers, its acts are unauthoritative, void, and of no force; that to this compact each state acceded as a state, and is an integral party; that this government, created by this compact, was not made the exclusive or final judge of the extent of the powers delegated to itself, since that would have made its discretion, and not the Constitution, the measure of its powers; but that as in all other cases of compact among parties having no common judge, _each party has an equal right to judge for itself, as well of infractions as of the mode and measure of redress_."
The Kentucky resolutions of 1799 go one step farther and give definite expression to the doctrine of nullification. They declare "that the several states who formed that instrument [the Constitution], being sovereign and independent, have the unquestionable right to judge of the infraction; and, _that a nullification, by those sovereignties, of all unauthorized acts done under color of that instrument, is the rightful remedy_."
The first clear and unequivocal statement of the doctrine of nullification may be traced to Jefferson. In the original draft of the Kentucky resolutions of 1798, which he wrote, it is asserted that where the Federal government assumes powers "which have not been delegated, a nullification of the act is the rightful remedy; that every state has a natural right in cases not within the compact (_casus non foederis_) to nullify of their own authority, all assumptions of power by others within their limits."[138] This was omitted, however, from the resolutions as finally adopted, although included in substance, as we have seen, in the Kentucky resolutions of 1799.
