The analysis stood out in a session that otherwise rehashed, on both sides, the perennial concerns of the broadband debate. The FCC chose not to appeal the decision.
Still, Genachowski said, in spite of that "open ground," the FCC's document "falls well within our authority in the Communications Act" and can coexist with the appellate decision.
Genachowski noted that his agency considered a different legal route to underpin the rules — Title II reclassification — but eventually backed off that approach when both parties expressed a strong distaste.
"We listened to that. We heard that. We didn't rely on Title II in adopting our final decision," he said.
Republicans on the panel felt strongly that the FCC had exceeded its authority.
"You ought to be real sure you have the authority … or if you're even questioning the authority, you should come to the people's house," said Rep. Adam Kinzinger (R-Ill.).
Communications subcommittee Chairman Greg Walden (Ore.) said if the rules are not challenged, "this claim of authority would allow the FCC to regulate any matter it discussed in the national broadband plan."
