What were chief justice taneys arguments to support his ruling?

Answer 1

Chief Justice Roger B. Taney's arguments in the Dred Scott v. Sandford case centered on the notion that African Americans, whether enslaved or free, could not be considered U.S. citizens and therefore had no right to sue in federal court. He claimed that the Constitution did not intend to include them as citizens and argued that Congress lacked the authority to regulate slavery in the territories, declaring the Missouri Compromise unconstitutional. Taney's ruling reinforced the institution of slavery and heightened tensions leading up to the Civil War.
