In late July 2009, Representatives Edward Markey (D-MA) and Anna Eshoo (D-CA) introduced H.R. 3458, the Internet Freedom Preservation Act of 2009, a bill to require Internet access providers to comply with specific net neutrality mandates and to offer stand-alone Internet access service. It also would require the FCC to promulgate rules to implement the mandates. The bill’s chances of advancement for 2009 are unclear, given FCC Chairman Genachowski’s recent announcement that the FCC would institute a net neutrality rulemaking. Congress may wait to see how the FCC proceeds, and could also hold legislation pending the resolution of Comcast’s challenge in the U.S. Circuit Court of Appeals for the D.C. Circuit challenge of the Commission’s authority to regulate Internet services.
