What three points did the Chief Justice Roger B Taney make in his decisions?

Chief Justice Roger B. Taney, in his most notable decision in Dred Scott v. Sandford (1857), made three key points: first, he ruled that African Americans, whether enslaved or free, could not be considered citizens and therefore lacked the standing to sue in federal court. Second, he declared that the federal government had no authority to regulate slavery in the territories, effectively nullifying the Missouri Compromise. Lastly, Taney asserted that enslaved individuals were property, and the Fifth Amendment protected the rights of slaveholders to their property, thus reinforcing the institution of slavery.
