Explanation:

In the decision Dred Scott v. Sandford (1857), the Supreme Court listened to the case of a slave who was suing his owners for his liberty. He believed that the fact that they had taken him to a free state meant that he should be able to acquire his freedom.

The decision greatly angered Northern abolitionists.
