"Where, in the performance of its judicial duties, the Court decides a case in such a way as to resolve the sort of intensely divisive controversy reflected in Roe and those rare, comparable cases, its decision has a dimension that the resolution of the normal case does not carry. It is the dimension present whenever the Court's interpretation of the Constitution calls the contending sides of a national controversy to end their national division by accepting a common mandate rooted in the Constitution."
The Court failed in Casey to will the Nation "to end their national division." There was no consensus in 1973, in 1992, and and there is none in 2017. It is still an issue, Jimbo.
