The BEST summary of the impact of the Supreme Court decision in Dred Scott v. Sandford (1857) is that it was a victory for slavery advocates in the South and invalidated the Missouri Compromise. To understand this, we can look at the details of the case. The Dred Scott case involved a slave named Dred Scott who sued for his freedom after living in free territories. The Supreme Court's decision in favor of Sandford (Scott's owner) had several significant impacts. Firstly, it declared that enslaved people were property, not citizens, and therefore did not have the right to sue in federal court. This decision, in effect, denied enslaved people access to the legal system for asserting their rights. Secondly, the Court ruled that the Missouri Compromise of 1820, which prohibited slavery in certain territories, was unconstitutional. The decision overturned the compromise's ban on slavery in the northern territories and opened the door for the expansion of slavery into new territories. Thus, it was a victory for slavery advocates in the South and invalidated the Missouri Compromise.
