Answer:
the Supreme Court ruled that Congress could not outlaw slavery anywhere in the United States.
Explanation:
In the Dred Scott v. Stanford case 1847, Dred Scott sued for freedom citing that as far as he has visited two free states he is automatically a free individual and cannot be re-enslaved. However he lost the case. In 1854, the case was brought to United States Supreme Court and Chief Justice Roger Taney rules against him. In his ruling, he said that all people of African descent, free or slave, were not United States citizens and therefore had no right to sue in federal court. he also wrote that the Fifth Amendment protected slave owner rights because slaves were their legal property.
