May a damages class be certified if the proponent of certification is unable to show a reliable, administratively feasible way to identify putative class members? Federal circuit courts continue to answer this question in varying ways, with the Eleventh Circuit last week contributing to a deepening division of federal authority on what is required of a proposed class representative in order to demonstrate the existence of an ascertainable Rule 23(b)(3) class. In Cherry v. Dometic, 2021 WL 346121 (11th Cir. Feb. 2, 2021), the court departed from unpublished decisions from other Eleventh Circuit panels and emphatically declined to adopt a requirement imposed by three circuits that plaintiffs show the existence of a reliable and administratively feasible mechanism to identify absent class members as a precondition to class certification. The role of class ascertainability and whether identification of putative class members is administratively feasible present fundamental questions that recur across a range of class actions, especially consumer and securities litigations.
