That the principle and construction contended for by sundry of the state legislatures, that the general government is the exclusive judge of the extent of the powers delegated to it, stop nothing short of despotism; since the discretion of those who administer the government, and not the constitution, would be the measure of their powers: That the several states who formed that instrument, being sovereign and independent, have the unquestionable right to judge of its infraction; and that a nullification, by those sovereignties, of all unauthorized acts done under colour of that instrument, is the rightful remedy.
