General SummaryThis case is from a collection containing the full text of over 16,000 Supreme Court cases from 1793 to the present. The body of Supreme Court decisions are, effectively, the final interpretation of the Constitution. Only an amendment to the Constitution can permanently overturn an interpretation and this has happened only four times in American history.
