The importance of the Force Bill is that it is the first piece of legislation to publicly deny the right of secession to individual states. Its approval meant that the principle of secession was no longer in keeping with the idea of a national union. In a presidential proclamation to the people of South Carolina, Jackson stated:
Seduced as you have been, my fellow countrymen by the delusion theories and misrepresentation of ambitious, deluded & designing men, I call upon you in the language of truth, and with the feelings of a Father to retrace your steps. As you value liberty and the blessings of peace blot out from the page of your history a record so fatal to their security as this ordinance will become if it be obeyed. Rally again under the banners of the union whose obligations you in common with all your countrymen have, with an appeal to heaven, sworn to support, and which must be indissoluble as long as we are capable of enjoying freedom. Recollect that the first act of resistance to the laws which have been denounced as void but those who abuse your confidence and falsify your hopes is Treason, and subjects you to all the pains and penalties that are provided for the highest offence against your country. Can (you)...consent to become Traitors? Forbid it Heaven!
The issue of nullification was a precursor to the American Civil War. Nullification is not specifically shown in the constitution; however neither is it specifically precluded and hence might be penumbrally retained and/or reserved under the Ninth and Tenth Amendments.
The Force Bill was later used by President Eisenhower when schools in Little Rock, Arkansas refused to integrate their schools. The 101st Airborne Division was sent in to Little Rock to protect the African-Americans who were going to white schools at that time.
