The statement that best describes the Supreme Court ruling in the Dred Scott Case is: "Scott as a slave was not a citizen and therefore had no right to sue."
In the 1857 decision, the Supreme Court ruled that Dred Scott, an enslaved African American man, was not a citizen of the United States and thus did not have the legal standing to bring a lawsuit. The ruling further stated that laws prohibiting slavery in certain territories were unconstitutional, effectively advancing the pro-slavery stance and deepening the national divide on the issue.
