“ The United States does not seek review of the ruling that Chairman Dixon was disqualified from participating in this case. We therefore venture no opinion as to the correctness of that conclusion. The petition for writ of certiorari is granted. The judgment of the United States Court of Appeals for the District of Columbia Circuit is vacated and the case is remanded with instructions to remand it immediately to the Federal Trade Commission for further proceedings, without the participation of Chairman Dixon, in light of Atlantic Refining Co. ”

“ The majority of the court held, further, that the Commission's order was not supported by substantial evidence on the record as a whole. Although it recognized that under these circumstances a remand would ordinarily be called for, the court concluded that because of the delays that had existed throughout the litigation the complaint should be dismissed. ”
