Some of the bills now pending before Congress propose to deprive the federal courts of the power to issue preliminary injunctions in these cases. This would be a policy fraught with immeasurable danger to property interests as well as to personal liberty. It would frequently amount to a complete denial of justice. The delay of litigation might readily be attended by ruin. But, undoubtedly, some reform is called for. There can be no question that preliminary injunctions against the enforcement of state statutes regulating public service corporations should never be granted without prior notice to the representatives of the people, and full opportunity for them to be heard, and then only upon the clearest showing of threatened irreparable injury pending the delay of a full hearing on the merits. Such cases ought not only to be given the earliest possible hearing, but the courts should insist that both sides proceed with the utmost expedition in the taking of testimony. A hearing in open court and not before a master would greatly facilitate this result. The people are entitled to a speedy determination of the questions involved in order that they may promptly have the benefit of the statute if it be constitutional, or that they may at once amend it if it be unconstitutional. There is no reason why in the majority of cases such a suit should not be ready for final hearing and actually be heard within sixty days, or why it should not be finally disposed of in the appellate courts within less than a year. It should have preference on all calendars. The Expedition Act of Congress, applicable to cases arising under the Anti-Trust and Interstate Commerce laws, would furnish a good model for cases involving the validity of state laws.
