What did the Supreme Court decide in the Dred Scott decision? Slavery was a choice each state could make

Slaves were property

Slaves were citizens.

Slavery was illegal

The Dred Scott decision was the U.S. Supreme Court's ruling on March 6, 1857, that having lived in a free state and territory did not entitle an enslaved person, Dred Scott, to his freedom. In essence, the decision argued that, as someone's property, Scott was not a citizen and could not sue in a federal court.
