A group of more than 20 attorneys general, including New York's Eric Schneiderman, has already announced its plan to legally challenge the repeal, as have a number of other groups, including the National Hispanic Media Coalition, Public Knowledge, and Free Press.
Congressional aides say the publication will trigger a 60-legislative-day deadline for Congress to vote on whether to overturn the decision.
While the filing may feel like the final nail in the coffin, so to speak, the fight for a free and open internet is far from over.
The state governments "are doing what the FCC chose not to do - listening to consumers who overwhelmingly support net neutrality rules - and sending a strong message to internet service providers looking to do business in their states", says Schwantes.
The rule was also unlawful because it includes "sweeping preemption of state and local laws", he said.
Net neutrality laws were created during the Obama administration and barred broadband companies from blocking access or slowing down the performance of certain websites and online services.
"It turned a blind eye to all kinds of corruption in our public record - from Russian intervention to fake comments to stolen identities in our files", she said.
The FCC's opponents argue that eliminating net neutrality principles will lead to internet service providers discriminating against some content and poorer service for subscribers. "The FCC is on the wrong side of history and the wrong side of the law and it deserves to have its handiwork revisited, reexamined and ultimately reversed".
The order will be officially published tomorrow in the Federal Register.
Democrats have enough votes to force an up-or-down vote on the bill through the Senate, and if they can get just one more Republican senator to flip, it'll pass.
Separately, governors in five states - Montana, New Jersey, New York, Hawaii, and Vermont - have passed Executive Orders requiring any ISP with a state contract to adhere to net neutrality.
In addition to NY, attorneys general from California, Connecticut, Delaware, the District of Columbia, Hawaii, Illinois, Iowa, Kentucky, Massachusetts, Maine, Maryland, Minnesota, Mississippi, New Jersey, New Mexico, North Carolina, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia and Washington joined Thursday's petition.
