EFF: “In a ruling that imposes important limits on the FCC’s authority to regulate the Internet, the D.C. Circuit Court of Appeals today overturned the FCC ruling against Comcast for interfering with the BitTorrent traffic of its subscribers. The court found that the Commission had overstepped the limits of its “ancillary authority” when it disciplined Comcast for its clandestine blocking behavior. The ruling is not likely to make much difference to Comcast subscribers—Comcast had already agreed to cease its BitTorrent interdiction before the FCC’s ruling was issued. Instead, the court’s ruling is important because it represents a blow to FCC Chairman Genachowski’s proposed net neutrality regulations, which are premised on the same theory of “ancillary jurisdiction” that the FCC used against Comcast and that the court rejected today.”
