Web browser developer Mozilla has filed a petition against the Federal Communications Committee (FCC) over its recent decision to overturn the 2015 Open Internet Order.

The suit has been filed in the federal court in Washington DC in the view that the FCC has actually violated federal law with its decision, and that the decision harms internet users and innovators.

“The internet is a global, public resource. It relies on the core principle of net neutrality (that all internet traffic be treated equally) to exist,” said Denelle Dixon, chief business and legal officer at Mozilla, in a blog post. “If that principle is removed — with only some content and services available or with roadblocks inserted by ISPs to throttle or control certain services — the value and impact of that resource can be impaired or destroyed.

“Ending net neutrality could end the internet as we know it. That’s why we are committed to fighting the order.”

Mozilla has said that it may need to file the petition once again, because the FCC decision states that suits should be filed 10 days after it is published in the Federal Register – which has not yet occurred.

On top of filing the suit, Mozilla is also urging Congress and the courts to fix the broken policies surrounding the open internet and net neutrality.
