The test of reasonableness was never applied by the court at common law to contracts or combinations or conspiracies in restraint of trade whose purpose was or whose necessary effect would be to stifle competition, to control prices, or establish monopolies. The courts never assumed power to say that such contracts or combinations or conspiracies might be lawful if the parties to them were only moderate in the use of the power thus secured and did not exact from the public too great and exorbitant prices. It is true that many theorists, and others engaged in business violating the statute, have hoped that some such line could be drawn by courts; but no court of authority has ever attempted it. Certainly there is nothing in the decisions of the latest two cases from which such a dangerous theory of judicial discretion in enforcing this statute can derive the slightest sanction. FORCE AND EFFECTIVENESS OF STATUTE A MATTER OF GROWTH. We have been twenty-one years making this statute effective for the purposes for which it was enacted. The Knight case was discouraging and seemed to remit to the States the whole available power to attack and suppress the evils of the trusts. Slowly, however, the error of that judgment was corrected, and only in the last three or four years has the heavy hand of the law been laid upon the great illegal combinations that have exercised such an absolute dominion over many of our industries. Criminal prosecutions have been brought and a number are pending, but juries have felt averse to convicting for jail sentences, and judges have been most reluctant to impose such sentences on men of respectable standing in society whose offense has been regarded as merely statutory. Still, as the offense becomes better understood and the committing of it partakes more of studied and deliberate defiance of the law, we can be confident that juries will convict individuals and that jail sentences will be imposed. THE REMEDY IN EQUITY BY DISSOLUTION. In the Standard Oil case the Supreme and Circuit Courts found the combination to be a monopoly of the interstate business of refining, transporting, and marketing petroleum and its products, effected and maintained through thirty-seven different corporations, the stock of which was held by a New Jersey company. It in effect commanded the dissolution of this combination, directed the transfer and pro rata distribution by the New Jersey company of the stock held by it in the thirty-seven corporations to and among its stockholders; and the corporations and individual defendants were enjoined from conspiring or combining to restore such monopoly; and all agreements between the subsidiary corporations tending to produce or bring about further violations of the act were enjoined.
