A federal appeals court on Tuesday issued a mixed ruling on the Federal Communications Commission repeal of Obama-era net neutrality rules. The court upheld the FCC’s repeal of the rules, but struck down a key provision that blocked states from passing their own net neutrality protections.

The case pitted Mozilla and several other internet companies, such as Etsy and Reddit, as well as 22 state attorneys general, against the Republican-led FCC. They argued that the FCC hadn’t provided sufficient reason for repealing the rules.

Following the ruling, Mozilla said it’s still considering its next steps. But the company, best known for its Firefox browser, has vowed to continue fighting for net neutrality protections. It’s also encouraged by the part of the decision that struck down the FCC’s blanket preemption of state net neutrality laws. This will “free states to enact net neutrality rules to protect consumers,” Amy Keating, chief legal officer for Mozilla, said in a statement. 

Other net neutrality supporters are also focusing on the state preemption issue. Gigi Sohn, an adviser to former FCC Chairman Tom Wheeler, who helped write the 2015 net neutrality rules, said this gives states an opportunity to protect consumers. 

“The DC Circuit Court has spoken very clearly —  the states are now free to do what the FCC will not — assert authority over the broadband market and protect an open Internet,” she said. “Broadband providers will inevitably complain about having to comply with a so-called ‘patchwork’ of different state laws, but that is of their own making.”
