Sandford, 60 U.S. (19 How.) 393 (1857), commonly referred to as The Dred Scott Decision, was a decision by the United States Supreme Court that ruled that people of African descent imported into the United States and held as slaves, or their descendants . whether or not they were slaves, were not protected by the Constitution and could never be citizens of the United States. It also held that the United States Congress had no authority to prohibit slavery in federal territories. The Court also ruled that because slaves were not citizens, they could not sue in court. Lastly, the Court ruled that slaves as chattel or private property, could not be taken away from their owners without due process. The Supreme Court's decision was written by Chief Justice Roger B. Taney.
