Following the principles developed in Mr. Calhoun's letter of August 28th, 1832, Governor Hamilton issued a call for a special session of the legislature of South Carolina, in the autumn of 1832, for the purpose of effecting through it the assembly of the convention of the Commonwealth. The party in favor of nullification had at last secured both branches of the legislature, and on October 24th, 1832, the assembled legislature voted to issue the call for the convention, and appointed November 19th as the day upon which it should meet. [Sidenote: The work of the Nullification Convention.] The convention assembled at the time designated, elected Governor Hamilton as its chairman, and appointed a committee of twenty-one members to consider the situation and report a proposition to meet it. In due time this committee made its report to the convention, in which was contained, first, a review of the development of the tariff from a revenue measure to a measure for the protection of manufactures, of the ten years of fruitless struggle in Congress by the South against the oppression inflicted by the protective system upon that section, and of the theories advanced by the fathers of the Republic for meeting, in last instance, such a condition of affairs; and, second, the famous Ordinance of Nullification as the remedy of last resort. The convention voted to receive the report and to adopt its recommendations. {222} On November 24th the convention passed, in solemn form, the Ordinance of Nullification of the existing tariff laws of the United States. [Sidenote: The Nullification Ordinance.] The convention declared and ordained in this instrument, that "the several acts and parts of acts of the Congress of the United States, purporting to be laws for the imposing of duties and imposts on the importation of foreign commodities, and now having actual operation and effect within the United States, and, more especially," the Act of May 19th, 1828, and that of July 14th, 1832, "are unauthorized by the Constitution of the United States and violate the true meaning and intent thereof, and are null and void and no law, nor binding upon this State, its officers or citizens; and all promises, contracts, and obligations made or entered into, or to be made or entered into, with purpose to secure the duties imposed by the said acts, and all judicial proceedings which shall be hereafter had in affirmance thereof, are and shall be held utterly null and void."
