Does the Court of Appeal have any authority to overturn a final disposition?

"It is settled law, however, that '[t]he conclusive effect of a final disposition is not to be disturbed by a subsequent change in decisional law' [citing cases]. The principle applies even when the change heralds a new policy as important as the relative apportionment doctrine evolved in Dole v. Dow Chem. Co. [citing cases]. That the change in legal doctrine is constitutional in nature does not, automatically, dictate a different result. It may be that where a final adjudication affects "important ongoing social or political relationships", a subsequent major change in constitutional doctrine should permit reconsideration of the original claim, at least as to its future effect [citation]. That possibility need not be addressed, for the situation posited is not presented in this case." ⁵
