John Marshall Harlan II,
Federal Trade Commission v. Mary Carter Paint Company…
“ In administering § 5 in the context of the many elusive questions raised by modern advertising, it is the duty of the Commission to speak and rule clearly so that law-abiding businessmen may know where they stand. In proscribing a practice uncomplained of by the public, effectively harmless to the consumer, allowed by the Commission's long-established policy statement, and only a hairbreadth away from advertising practices that the Commission will continue to permit, I think that the Commission in this instance has fallen far short of what is necessary to entitle its order to enforcement. ”
