James Clark McReynolds,
United States v. American Linseed Oil Company…
“ In the absence of a purpose to monopolize, or the compulsion that results from contract or agreement, the individual certainly may exercise great freedom; but concerted action through combination presents a wholly different problem, and is forbidden when the necessary tendency is to destroy the kind of competition to which the public has long looked for protection. The situation here questioned is wholly unlike an exchange, where dealers assemble and buy and sell openly, and the ordinary practice of reporting statistics to collectors stops far short of the practice which defendants adopted. ”
