[JURIST] The US Supreme Court on Monday upheld an FCC determination [FCC press release] that broadband cable modem companies are free from the mandatory regulations that apply to common-carriers. The 6-3 ruling means cable companies are allowed to keep rival internet providers from using their lines, a decision that lessens competition and consumer choice. The decision is likely to be seen as a victory for a Bush administration seeking to promote broadband investment. Read the Court's opinion [PDF] in the consolidated cases of Nat'l Cable and Telecomm.
