Why did Andrew Jackson believe that one state could not decide which federal laws to obey?
President Andrew Jackson rejected the doctrine of nullification because he viewed it as fundamentally incompatible with the existence of the United States and a direct threat to national authority.12
In his December 1832 proclamation to the people of South Carolina, Jackson argued that the U.S. Constitution did not permit a state to remain in the Union while simultaneously choosing which federal laws to obey. He contended that granting a state the power to unilaterally declare an act of Congress void and prohibit its execution would effectively grant that state the power to resist all federal laws.12
Jackson maintained that such a position was "contradicted expressly by the letter of the Constitution" and warned that any attempt to achieve disunion through armed force constituted treason. By asserting the supremacy of the federal government, Jackson sought to preserve the integrity of the Union against the states' rights theory advocated by John C. Calhoun, which claimed that individual states held the final authority to judge the constitutionality of federal legislation.12
