Answer :
Answer:
D. Slaves were blocked from bringing lawsuits in courts because they
weren't citizens.
Explanation:
By a 7-2 vote, the US Supreme Court decided that black slaves were not American citizens - thus reinforcing the notion of them as simple property - so, they could not sue their white masters in court. Besides, having lived in a free state as a free man did not entitle a black person to be freed in a slavery state if he had fallen into slavery. The Dred Scott decision of the late 1850s is the most infamous judicial sentence ever written in the US.
