We previously reported on the Gannon v. Metwork Telephone Services, Inc., decision where the District Court denied class cert in a TCPA class action.  (http://www.calautofinance.com/?p=4181).  In Gannon v. Network Telephone Services, Inc., 2016 WL 145811, at *1 (9th Cir. 2016) (unpublished), the Court of Appeals for the Ninth Circuit affirmed the District Court’s denial of class certification.

Paul Gannon challenges the district court’s denial of class certification in his suit under the Telephone Consumer Protection Act, 47 U.S.C. § 227. We have jurisdiction of this appeal under 28 U.S.C. § 1291 because the parties stipulated to dismissal of Gannon’s Second Amended Complaint. We affirm.  . . . Gannon’s proposed class includes all recipients of “unauthorized” text messages from Network Telephone Services (“NTS”). The central issue in the case is whether the text messages were unauthorized. But, the proposed class includes at least the following groups: (a) those, like Gannon, who claim to have called an NTS phone line by mistake and may have discontinued the call before hearing the “mid-amble” that informed the caller of NTS’s intent to send future text messages; (b) those who heard the mid-amble and did not follow its instructions as to how to opt out of receiving text messages; and (c) those who called the NTS phone line in response to an advertisement that expressly promised future text messages. To determine liability, the district court would be required to determine whether under each of these different factual scenarios—and undoubtedly others—the caller agreed to receive text messages. Given “the significance of those uncommon questions,” the district court did not abuse its discretion by finding the requirements of Rule 23(b)(3) unsatisfied. See Amchem Prods., Inc. v. Windsor, 521 U.S. 591, 624 (1997).  The district court did not abuse its discretion by finding that the members of the proposed class were not readily ascertainable. See, e.g., Williams v. Oberon Media, Inc., 468 F. App’x 768, 770 (9th Cir.2012); In re NJOY, Inc. Consumer Class Action Litig., ––– F.Supp.3d ––––, 2015 WL 4881091, *23 (C.D.Cal. Aug. 14, 2015). The district court appropriately determined that it would be extremely difficult to ascertain the identities of the individuals who had not consented to receive the messages.
