A coalition of trade groups recently petitioned the Federal Communications Commission (the “Commission”), urging it to adopt a narrow interpretation of “Automated Telephone Dialing System” (“ATDS” or, commonly, “autodialers”) under the Telephone Consumer Protection Act (“TCPA”). The petition, filed on behalf of the U.S. Chamber of Commerce and other trade associations, follows the March 2018 decision of the U.S. Court of Appeals for the D.C. Circuit that vacated several key elements of the Commission’s 2015 TCPA Order. ACA Int’l v. Fed. Comm. Comm’n, 885 F.3d 687, 692, 701 (D.C. Cir. 2018). Among other things, the D.C. Circuit set aside the Commission’s 2015 interpretation of what constitutes an ATDS. The court held that the Commission’s interpretation of the term ATDS was “unreasonably expansive” and “‘offer[ed] no meaningful guidance’ to affected parties in material respects on whether their equipment is subject to the statute’s autodialer restrictions.” Because of the limited scope of the matter before it, the D.C. Circuit did not itself interpret the term ATDS, but instead provided guidance for the Commission as to how the term should be defined.
