In 1857, the Supreme Court heard the case of Dred Scott, a slave whose master moved him to a free state and then died. Roger B. Taney, Chief Justice of the Supreme Court at the time, was completely proslavery and anti-Republican. Therefore, his decision went accordingly, ruling that slaves are property, and property can’t be taken away without due process of the 5th Amendment. This translated that Congress didn’t have the authority to ban slavery anywhere because it is unconstitutional to take property. In accordance with this ruling, the Northwest Ordinance, Missouri Compromise, Wilmot Proviso, and the Kansas-Nebraska Act were all deemed unconstitutional. This proved to be a major victory for the South since slavery could be constitutionally moved anywhere now, but the North denounced this decision.
