In brief
Overview
Petitioners argue they were not named plaintiffs in the prior federal proceeding and never received notice, an opportunity to be heard, to opt out, or to appeal the denial of class certification.
According to Petitioners, petitioners assert that procedural rights, including due process, must be adjudicated consistently and that West Virginia may apply and interpret its own Rule 23 as it sees fit.
According to MR. MONAHAN, monahan states that the Court has recognized a procedural right to seek class certification, but there is no substantive right to obtain it.
According to MR. BECK, beck frames the core issue as whether absent class members can be bound by a denial of class certification when there was adequate representation on the issue but no notice or opportunity to be heard.
Background and question before the Court
Justice Alito asked whether the petitioners’ argument would be the same if, after a denial of class certification in one West Virginia district, the same plaintiff filed the identical complaint in another district and sought certification again.
According to Justice Ginsburg, justice Ginsburg questioned whether simply obtaining a new named plaintiff would satisfy the requirements for a class action.
According to Justice Kagan, justice Kagan inquired whether a federal Rule 23 decision can ever be preclusive with respect to a state Rule 23.
Justice Kagan also asked whether Congress, when enacting the Class Action Fairness Act, contemplated the issue of a lawyer filing in different states with different named plaintiffs.
According to Justice Breyer, justice Breyer queried whether there is any precedent of a plaintiff seeking class certification in a different federal court after a denial in another court.
Justice Scalia asked whether a subsequent plaintiff who was not given notice or an opportunity to opt out would be bound by a prior denial of class certification, even if the later filing is in the same court.
According to Justice Kagan, justice Kagan noted that the case was dismissed because a summary‑judgment motion was granted, not because of the denial of class certification.
According to Justice Scalia, justice Scalia observed that a party attempting to bring a later class action cannot do so because a prior class action was denied.
