Broadband industry lobby groups have appealed to the US Supreme Court in an attempt to kill the Federal Communications Commission's network neutrality rules. The groups want the Supreme Court to rule that the FCC exceeded its authority when it reclassified Internet providers in order to impose stricter regulations. Such a ruling could prevent future FCCs from implementing net neutrality rules as strict as the current ones, which outlaw blocking, throttling, and paid prioritization. A ruling for the industry could also prevent future FCCs from reviving other consumer protections that are likely to be overturned by the commission's current Republican majority.
Lobby groups also allege that the FCC didn't do enough to justify its decision and that it didn't follow the required administrative procedures. But for potential long-term impact, the question of whether the FCC has the authority to classify broadband as a common carrier service is probably more significant. Whether the Supreme Court will actually decide to hear the case is far from certain.
