Sandford (argued 1856 -- decided 1857), the Supreme Court ruled that Americans of African descent, whether free or slave, were not American citizens and could not sue in federal court. The Court also ruled that Congress lacked power to ban slavery in the U.S. territories. Finally, the Court declared that the rights of slaveowners were constitutionally protected by the Fifth Amendment because slaves were categorized as property.
