I support that dred scoot was the worst supreme court ruling in American history.
Step-by-step explanation:
In Dred Scoot v Stanford, which was argued in 1856 and was decided in the year 1857, the decision taken by the Supreme court was that the American of African descent, whether free or slave were not American citizens. Neither could they sue in the federal court.
In this case, the supreme court decided that the congress did not have the power that was required to ban slavery in the territories in the United States of America. Therefore it was a great threat to liberalism and the right to equality.
