What were the two most important decisions that came out of the supreme courts dred Scott decision?

The Dred Scott decision, issued in 1857, primarily established two critical points: first, it ruled that African Americans, whether enslaved or free, could not be considered American citizens and therefore had no right to sue in federal court. Second, the Court declared that the federal government lacked the authority to regulate slavery in the territories, effectively nullifying the Missouri Compromise and intensifying sectional tensions leading up to the Civil War.
