The term 'SCOTT IN A SUPREME COURT CASE' refers to the landmark case of Dred Scott v. Sandford, which was decided by the United States Supreme Court in 1857. The case involved a slave named Dred Scott who sued for his freedom after being taken by his owner into a free state. The court ruled that Scott was not a citizen and therefore could not sue in federal court. This ruling had far-reaching implications for the future of slavery in the United States.
