Final answer:
The Supreme Court's decision in the Dred Scott case determined that enslaved people were not citizens but property.
Step-by-step explanation:
The result of the Supreme Court's decision in the Dred Scott case was that an enslaved person was not a citizen but rather the property of an owner. In this landmark case of 1857, the Court ruled that enslaved people were not considered citizens and therefore did not have the right to sue for their freedom in federal courts. The decision also stated that Congress did not have the power to prohibit slavery in any territory, which further strengthened the institution of slavery.
