Birchmeier, et al. v. Caribbean Cruise Line, Inc., Case No. 12 C 4069 (N.D. Ill. 2014), here, Judge Kennelly certified two nationwide classes of individuals who received robocalls offering a free cruise trip for participation in a political survey. The plaintiffs alleged that these robocalls violated the TCPA. Between August 2011 and August 2012, millions of calls were made, and approximately 930,000 telephone numbers that received the calls were produced in discovery. Defendants opposed class certification on a number of grounds, including that (a) the class was not ascertainable because there is no practical way to identified the subscriber of the number that was called during the 2011/2012 period, (b) each class member had different caller experiences, dependent on: the length of call, whether caller took the survey, and type of phone plans, (c) none of the named plaintiffs appeared in the list of the approximately 930,000 numbers who unquestionably received a call from the defendants, and (d) liability and damages depend on individualized proof. The District Court certified the class anyway, holding that “plaintiffs need not establish that the people who received the calls at the numbers on the list of 930,000 were the actual subscribers; the fact that they received calls is enough to permit them to sue.” Further, limiting the class membership to only those who appear in the defendants records is “fundamentally unfair” because individuals who can submit a claim with documentation of their cellular telephone records ought also be classmembers.
