Sandford case of 1857, popularly known as the "Dred Scott Decision". Scott claimed that he and his wife should be granted their freedom because they had lived in Illinois and the Wisconsin Territory for four years, where slavery was illegal . The United States Supreme Court decided 7--2 against Scott, finding that neither he nor any other person of African ancestry could claim citizenship in the United States, and therefore Scott could not bring suit in federal court under diversity of citizenship rules . Moreover, Scott's temporary residence outside Missouri did not bring about his emancipation under the Missouri Compromise, which the court ruled unconstitutional as it would "improperly deprive Scott's owner of his legal property". </P> <P> While Chief Justice Roger B. Taney had hoped to settle issues related to slavery and Congressional authority by this decision, it aroused public outrage, deepened sectional tensions between the northern and southern U.S. states, and hastened the eventual explosion of their differences into the American Civil War . President Abraham Lincoln's Emancipation Proclamation in 1863, and the post-Civil War Reconstruction Amendments--the Thirteenth, Fourteenth and Fifteenth amendments--nullified the decision . </P>
