On August 29th, a Ninth Circuit panel unanimously held that the FTC has no power to challenge “throttling” of unlimited data plan customers by mobile broadband providers as an “unfair or deceptive act.”  The panel found that a core source of FTC authority (Section 5 of the FTC Act) does not apply to any “common carriers” that are subject to regulation under the Communications Act of 1934.  (FTC v. AT&T Mobility LLC, No. 14-04785 (9th Cir. Aug. 29, 2016)).
