On July 1, 1832, before Calhoun resigned the vice presidency to run for the Senate, where he could more effectively defend nullification, Jackson signed into law the Tariff of 1832. This compromise tariff received the support of most Northerners and half the Southerners in Congress. But it did not satisfy South Carolina, and on November 24, 1832, a state convention adopted the Ordinance of Nullification, which declared that the Tariffs of 1828 and 1832 were unconstitutional and unenforceable in South Carolina after February 1, 1833. South Carolina initiated military preparations to resist anticipated federal enforcement, but on March 1, 1833, Congress passed both the Force Bill—authorizing the President to use military forces against South Carolina—and a new negotiated tariff, the Compromise Tariff of 1833, which was satisfactory to South Carolina. The South Carolina convention reconvened and repealed its Nullification Ordinance on March 15, 1833, but three days later, nullified the Force Bill as a symbolic gesture of principle.
