An ongoing debate about the authority of the U.S. Federal Communications Commission (FCC) and the Federal Trade Commission (FTC) to regulate broadband may soon come to a head.  AT&T recently asked a U.S. district court to dismiss a complaint filed against it by the FTC.  The motion to dismiss challenges the FTC’s authority to regulate telephone companies providing broadband and raises complicated jurisdictional issues the resolution of which may depend on the outcome of the high-profile Open Internet proceeding currently pending at the FCC.
