Dred Scott v. Sandford Dred Scott v. Sandford, 60 U.S. 393 (1857) , also known simply as the Dred Scott case, was a landmark decision by the United States Supreme Court on US labor law and constitutional law. It held that "a negro, whose ancestors were imported into [the U.S.], and sold as slaves", whether enslaved or free, could not be an American citizen and therefore had no standing to sue in federal court, and that the federal government had no power to regulate slavery in the federal territories acquired after the creation of the United States. Dred Scott, an enslaved man of "the negro African race" who had been taken by his owners to free states and territories, attempted to sue for his freedom. In a 7–2 decision written by Chief Justice Roger B. Taney, the court denied Scott's request. The decision was only the second time that the Supreme Court had ruled an Act of Congress to be unconstitutional.
Thornhill v. Alabama Thornhill v. Alabama, 310 U.S. 88 (1940), was a United States Supreme Court case heard in 1938 and decided in 1940. It reversed the conviction of the president of a local union for violating an Alabama statute that prohibited only labor picketing. Thornhill was peaceably picketing his employer during an authorized strike when he was arrested and charged. In reaching its decision, Associate Justice Frank Murphy wrote for the Supreme Court that the free speech clause protects speech about the facts and circumstances of a labor dispute. The statute in the case prohibited all labor picketing, but "Thornhill" added peaceful labor picketing to the area protected by free speech.
