Viewpoint General
In this issue, we look at industry comments on the FCC’s report on robocalling and efforts to urge the agency to reconsider its reassigned numbers database proposal. In addition, we examine a recent circuit split on what constitutes an automatic telephone dialing system (ATDS) in the Third and Ninth Circuits and what that means for TCPA defendants. The split follows the D.C. Circuit’s May 2018 decision in ACA International v. Federal Communications Commission, which set aside the FCC’s “unreasonably expansive interpretation” of what constitutes an automatic telephone dialing system.

Viewpoint General
In May 2018, the D.C. Circuit set aside the FCC’s “unreasonably expansive interpretation” of what equipment constitutes an automatic telephone dialing system (“ATDS”). See ACA International v. Federal Communications Commission, No. 15-1211 at 5 (D.C. Cir. 2018). The FCC’s 2015 promulgations broadly interpreted the TCPA’s statutory language, subjecting “ordinary calls from any conventional smartphone to the Act’s coverage.” Id. at 5. This unconfined interpretation caused TCPA lawsuits and settlement figures to skyrocket. After ACA Int’l, technology needs to actually generate telephone numbers to qualify as an ATDS. In this post-ACA landscape, at least eight district courts have held that the FCC’s expansive rulings on the TCPA have been vacated.
