What was the primary question surrounding the 1832 to nullification crisis

The Nullification Crisis was a conflict over customs that broke out between the government of South Carolina and the federal government during the mandate of the American president Andrew Jackson.  The main stumbling block was the U.S. federal government’s effort to steadily increase tariff rates. From the first protective customs passed in 1816, the customs were increased twice more, in 1824 and 1828. The South was most affected by these measures. The center of dissatisfaction was South Carolina, whose assembly in December 1828 adopted a law to nullify federal laws concerning customs.

However, the nullification came into force only in 1832, after the enactment of a new customs law. Although the law reduced customs rates, they were still high for South Carolina. The nullificationists also sent an ultimatum to the federal government that if the federal government resorted to force, South Carolina would leave the Union.  Finally, South Carolina withdrew its order of nullification and accepted new tariffs, which ended this dispute.
