United Ates v. Bruno — Opinion of the Court
“ In some instances there was a subsequent adjustment of the price to conform to the price ceiling for the grade actually shipped. But in others there was not. And bearing on the integrity of the system were two other facts- (1) the debits made followed the OPA investigation; (2) the inflated prices were not disclosed on Bruno's books. In a seller's market upgrading may be a convenient device for black market operations. ”
