Several internet-dependent companies and advocacy groups earlier this week filed a brief in a petition before a federal appeals court in Washington, D.C., asking the court to review the Federal Communication Commission's decision last year to end Obama-era net neutrality rules.

Software developer Mozilla Corp., video-sharing service Vimeo LLC, and e-commerce site Etsy Inc., and numerous other technology advocacy groups and media companies filed the brief Monday in the U.S. Court of Appeals for the District of Columbia Circuit [#18-1051], joining a petition led by New York Attorney General Barbara Underwood and attorneys general of 21 other states and D.C. against the FCC order ending net neutrality.

Government petitioners in the case also filed a new brief on Monday that includes an addendum stating that firefighters battling wildfires in Northern California were hampered when their internet service provider, Verizon, slowed the internet speeds on the Fire Department's communications equipment and told them the only way to ramp up the speed was to pay for a new data plan. Verizon claimed a customer service error was responsible and not the net neutrality rollback, according to the Los Angeles Times and other accounts.

The Mozilla et al brief argues that the FCC's rationale for reclassifying broadband internet access service as an information service rather than as telecommunications, and delegating authority to the Federal Trade Commission and Department of Justice, is “unambiguously contrary to the law.”

The revised FCC rules under Chairman Ajit Pai, which took effect in June, were a win for big internet service providers, including AT&T, Comcast Corp. and Verizon Communications Inc. Large companies such as Facebook, Google and Amazon, however, put up opposition. The order also pre-empts states from passing regulation similar to the 2015 order.

The protective petition for review was filed in January with the appeals court by attorneys general from New York, California, Connecticut, Delaware, D.C., Illinois, New Jersey, Pennsylvania and Virginia, among others. The states claim that the FCC's order terminating “net neutrality” rules, which required that all internet traffic be treated equally, threatens public health and safety.

The governments' brief further argues that the FCC order was not only “arbitrary and capricious,” but unlawfully attempts to pre-empt state and local regulation. The petition asks the court to vacate and reverse the FCC order. Oral arguments are not yet scheduled.

In an addendum to the government brief filed by Santa Clara County Counsel, Underwood and the California Public Utilities Commission, Fire Chief Anthony Bowden made a declaration in which he claimed Verizon “throttled,” or slowed, the fire department's data connection speeds in the middle of battling the Mendocino Complex fires, and said the county would have to switch to a new data plan at more than twice the cost in order to increase the speed despite an emergency request.

Etsy and the Coalition of Internet Openness are represented by Steptoe & Johnson LLP lawyers Pantelis Michalopoulos, Cynthia Taub and Travis West. Steptoe lawyers Markham Ericson and Georgios Leris represent Mozilla and INCOMPAS. General counsel of Vimeo, Michael Chea, represents the company. A host of other lawyers represented other interested trade groups in the brief.

Meanwhile, in California, state net neutrality legislation was approved by a key Assembly committee and was headed to a floor vote in the chamber next week. The bill was approved by the state Senate in May. Legislation requiring net neutrality has been introduced in 29 states, according to the National Conference of State Legislatures in response to the Restoring Internet Freedom Order issued Jan. 4 that ended net neutrality as federal law. Governors in six states including Hawaii, Montana, New Jersey, New York, Rhode Island and Vermont have since signed executive orders requiring net neutrality within their states, and another three states—Oregon, Vermont and Washington—had enacted net neutrality legislation as of last month.

Pai said on CNBC in June that he did not believe that the states' efforts would be successful. “What we're going to do is take a look on a case-by-case basis at each state law and determine the right course, but at a broad level, the internet is inherently an interstate service,” he said.
