Stupid headline,the fcc does not have a vote........
Rule making at federal agencies is governed by the Administrative Procedure Act. If the FCC intended to adopt a new rule at its December meeting, it would have had to issue a Notice of Proposed Rulemaking, have gone through the public comment period, and so on. Administrative rules which are adopted without following the governing statutes are void.
The FCC has five commissioners, no more than three of which can be from the same political party. How do they decide things as a body? Volleyball game?
