In a speech delivered to the Brookings Institution, FCC Chairman Julius Genachowski confirmed that the FCC will soon launch rulemaking proceedings to implement the net neutrality principles adopted by the agency in 2005. Although the FCC cited those principles in its decision last year to hold Comcast accountable for certain web traffic management practices, the initiative unveiled on Monday would constitute the FCC’s first effort at officially regulating traffic and content carried across the Internet. The rulemaking also dovetails with the recent introduction of legislation, sponsored by former House Telecommunications and Internet subcommittee chairman Ed Markey (D-MA), that would amend the 1934 Communications Act to “protect the right of consumers to access lawful content, run lawful applications and use lawful services of their choice on the Internet.” Specifically, the rulemaking would codify existing FCC net neutrality principles that uphold the right of Internet users, among other things, to access lawful content of their choice and connect devices of their choice to Internet service provider (ISP) networks as long as such devices cause no harm to such networks. The proposed rules (which also apply to wireless ISPs) would also prohibit ISPs from selectively blocking or degrading web content or applications and would further require ISPs to disclose fully their network management practices to consumers. Although the plan has been endorsed by FCC Commissioners Michael Copps and Mignon Clyburn, the FCC’s Republican minority consisting of Commissioners Robert McDowell and Meredith Baker expressed reservations about what they described as “a dramatic proposal to grow government’s involvement in Internet governance and management” that is “monumental in . . . scope.” While AT&T, Comcast and other affected carriers urged the FCC to gather evidence of actual market abuses before it enacts any rules, Kay Bailey Hutchison (R-TX) was joined by five other Senate Republicans in introducing an amendment to pending appropriations legislation that would “prohibit the FCC from expending funds to develop and implement new regulatory mandates,” as Hutchison told reporters: “the case has simply not been made for what amounts to a significant regulatory intervention into a vibrant marketplace.”
