The Supreme Court's Decision in Plussy Versus Ferguson in 1897

Soisrel: Can a decision be overruled simply because it was erroneously wrong, even if nothing has changed between the time of that decision and the time when the court is called upon to consider whether it should be overruled? Soisrel: I still don't have your answer clearly. Is it your answer that we needed all the experience from 18 96 to 19 54 to realize that plussis was wrongly decided? Which answer my question?"
