Final answer:
Justice Taney used the 'originalist' view to argue that enslaved people were not intended to be citizens by the framers of the Constitution, influencing the Dred Scott decision that further entrenched the sectional divides over slavery and citizenship.
Step-by-step explanation:
Justice Roger B. Taney's view of the framers' "original intent" was used to articulate the Dred Scott v. Sandford decision. Taney believed that the Constitution should be interpreted as its framers intended, meaning that at the time the Constitution was written, enslaved people were not considered citizens. He asserted that, irrespective of whether an individual was born into slavery or freedom, Black people in the United States were not entitled to citizenship or civil rights. In his ruling, Taney declared that blacks could not be citizens of the United States and therefore had no standing to sue in federal court. This perspective also led to the statement that Congress had no authority to bar slavery in the territories, overturning the Missouri Compromise and inflaming the sectional divide over slavery.
