Explanation:

Dred Scott v. Standford was an 1857 court ruling that stated blacks, free or not, were not citizens of the U.S. If you are not a citizen of the United States you are not allowed to sue in a Federal court, but Dred Scott did. He stated he was actually in fact free, because he was living in a free territory. He eventually lost the case.
