Answer:
Dred Scott v. Sandford was a case brought before the United States Supreme Court in 1857, which deprived African Americans of federal judicial capacity and allowed slavery in the federal territories, declaring the Missouri Compromise as unconstitutional.
The judgment written by Supreme Court Chief Justice Roger B. Taney stated that African Americans could not be US citizens and therefore lacked federal legal capacity. The Court also found that Congress did not have the constitutional right to regulate slavery in the federal territories.
Roger B. Taney's vote, which was accepted by the majority of the Court, assumed that people of African race were not or could not become citizens under the United States Constitution. The Constitution, according to the sentencing ruling, gave Congress the right to regulate the federal territories, and only applied to the territories of the United States when the Constitution was ratified. The Missouri Compromise, which prohibited slavery in the territories that became part of the United States after the Mexican war, did not apply.
