View the complete text of the infamous Dred Scott v. Sandford Supreme Court Decision here.
On March 6th, 1857, Chief Justice Roger B. Taney delivered the majority opinion of the U.S. Supreme Court in the Dred Scott case. Seven of the nine justices agreed that Dred Scott should remain a slave, but Taney did not stop there. He also ruled that as a slave, Dred Scott was not a citizen of the United States, and therefore had no right to bring suit in the federal courts on any matter.
In addition, he declared that Scott had never been free, due to the fact that slaves were personal property; thus the Missouri Compromise of 1820 was unconstitutional, and the Federal Government had no right to prohibit slavery in the new territories. The court appeared to be sanctioning slavery under the terms of the Constitution itself, and saying that slavery could not be outlawed or restricted within the United States.
