Third Circuit Rejects Effort At End Run Around The Ascertainability Requirement

We previously wrote about the Third Circuit's decision in Carrera v. Bayer Corp., which reversed a district court's class-certification order because there was no reliable way to ascertain class membership—indeed, no way to identify who was a member of the class aside from a class member's own say-so. Last week, the full Third Circuit denied (pdf) the plaintiff's request to rehear the case en banc over the dissent of four judges. The clear message of Carrera is that when plaintiffs file class actions that have no hope of compensating class members for alleged wrongs because the class members can't be found, courts should refuse to let these actions proceed.

As we discuss below, the denial of rehearing is significant in itself, given the concerted efforts by Carrera and his amici to draw attention to the case. But what might be most significant about this latest set of opinions is what even the dissenting judges did not say.
