What is good for the goose is good for the gander. The saying often finds application in Washington, when a principle formerly benefiting one ideological side suddenly benefits the other due to the vagaries of the ballot box. The filibuster is a classic example. The respect that courts accord to agencies is another. In FCC v. Prometheus Radio Project, the Supreme Court reversed the Third Circuit and unanimously upheld the FCC’s relaxation of its media ownership rules, a significant deregulatory policy of the Trump Administration. But the wide latitude that the Supreme Court gave the Commission’s factual findings has become a valuable tool in the hands of the Biden-era FCC, as the FCC can command the same respect for crucial factual findings needed in support of quite different initiatives, such as new net neutrality rules. Meanwhile, in the proceeding at hand, media ownership, the Commission has subsequently issued a public notice to update the record in the 2018 Quadrennial Review proceeding for its media ownership rules and extended the comment and reply comment deadlines to September 2, 2021 and October 1, 2021, respectively.
