NEW YORK (CNNMoney) -- Verizon filed a legal appeal on Thursday challenging the Federal Communications Commission's authority to enforce the new Net neutrality rules it adopted last month.
"We believe this assertion of authority goes well beyond any authority provided by Congress, and creates uncertainty for the communications industry, innovators, investors and consumers," Verizon senior vice president and deputy general counsel Michael E. Glover said in a written statement
But the FCC's legal grounds for expanding its authority is shaky, and industry observers predicted that Internet providers would take the issue to court.
"Undoubtedly, there's going to be litigation against it," Rebecca Tushnet, a professor at Georgetown University who specializes in digital media, said at the time.
Enter Verizon (VZ, Fortune 500). The company was already in the thick of the Net neutrality fight after striking a backroom deal with Google (GOOG, Fortune 500) last year that it hoped would head off new FCC rules. It didn't.
The FCC has been through the legal wringer several times in its attempts to police Internet providers.
In 2007, Comcast -- the nation's largest Internet provider -- blocked its subscribers from using peer-to-peer file-sharing networks. The FCC tried to force Comcast to stop, and Comcast fought back with a lawsuit challenging the FCC's authority in the matter. In April 2010, a U.S. court of appeals ruled in Comcast's favor.
