"But the FCC's authority here is shaky, and some legal experts (like Stanford Professor Barbara van Schewick) have argued that when the FCC rolled back its Title II authority over ISPs, it also dismantled its right to tell these states what to do:
"The bill is on firm legal ground.
While the FCC’s 2017 Order explicitly bans states from adopting their own net neutrality laws, that preemption is invalid. According to case law, an agency that does not have the power to regulate does not have the power to preempt. That means the FCC can only prevent the states from adopting net neutrality protections if the FCC has authority to adopt net neutrality protections itself."
