Several states are filing a lawsuit, so this is likely going to court. The NY AG last night explained their case. I guess the FCC has to show some type of reason for making this change and he's asserting there is no real reason for it.

Additionally part of the lawsuit is the FCC's refusal to address whether they filtered out the millions of fraudulent comments that were submitted during the public open comment period. There is countless evidence of people's identities stolen to submit comments as well as comments from dead people.
