The fight to reinstate net neutrality rules could return to federal court, if consumer groups and tech companies including Mozilla get their way.

The maker of the Firefox Web browser joined other tech firms and public-interest advocates to fire their latest salvo Friday: They asked a panel of judges to rehear a case that upheld a Federal Communications Commission decision to repeal the government’s open-Internet rules.

In October, the U.S. Court of Appeals for the District of Columbia Circuit determined that the FCC acted lawfully when it voted in 2017 to unwind the protections that had required AT&T, Comcast, Verizon and other telecom giants to treat all Web traffic equally. The telecom agency’s repeal wiped out rules that prohibited broadband providers from blocking websites, throttling consumers’ connections or charging websites for faster delivery of their content or services.

But Mozilla, public-interest groups and trade associations representing Facebook, Google and other tech giants argued in filings that the D.C. Circuit erred in its reasoning. Some said judges misinterpreted decades-old legal precedent, giving the FCC too much leeway without considering the facts, and they asked some or all of the panel to reconsider the decision to uphold the repeal. Mozilla and its allies also faulted the FCC for having “abdicated its ability to regulate the behavior of ISPs for the first time in its history.”
