If the complaining company were as anxious to give the new tariff a fair trial as it usually is to demonstrate to the satisfaction of the court that it is devoid of every principle of justice, such a test might be accepted by the public as a reliable basis of judicial procedure. But railroad managers are not only striving to perpetuate their own high rates, but to show to the public that freight tariffs not emanating from a railroad company's office are of necessity crude and unjust to the carrier. They know that if they should succeed in convincing the public that administrative boards are incapable of dealing with that question, they might for years to come be left in undisputed possession of the power to make their own rates. This is certainly for the railroad manager a prize worth contending for, and no sacrifice is too great for him to make when there is any hope of ultimate victory. Being absolutely uncontrolled in his action, he finds it an easy matter, by temporarily diverting business from his line, by the increase of operating expenses and by repressing growing industries, and in many other ways, to curtail the business of his road and diminish its revenues. He can court losses in a thousand different ways discernible neither to the courts nor the general public. In short, it is in the power of any railroad manager to manipulate such a trial in his own interest, and, if determined, to obtain a verdict against any tariff not of his own making. This policy was pursued by several Iowa roads subsequent to Judge Brewer's decision that the alleged unreasonableness of the Iowa commissioners' tariff must be established by an actual trial, and was persevered in until the suit was withdrawn.
