When the law was passed its friends well realized that its success would greatly depend on the character of the commissioners whom it was incumbent upon the President to appoint. It was feared that if the railroad influence should control these appointments, the power to suspend the long and short haul clause would be the chief and perhaps the only power exercised by the commission. There was great danger that the office of Interstate Commerce Commissioner might become a sinecure for servile railroad lawyers, as similar State officers had been before, and that a public trust might be turned into an additional corporation agency for evil. The selection of the commissioners, and especially that of Judge T. M. Cooley, of Michigan, was greatly to the credit of President Cleveland. A man of unquestionable integrity, an eminent jurist and close student of railroad affairs, Judge Cooley was particularly well qualified for the office of chairman of the Interstate Commerce Commission, which he occupied for nearly five years with signal fitness, and from which he only retired to the sincere regret of the American people. Under Judge Cooley's leadership the commission has been more than a purely executive board. It was under the Constitution not in the power of Congress to clothe the Interstate Commerce Commission with full judicial authority without giving its members, like other Federal judges, tenure for life, instead of a term of years. The inherent force of the commission's decisions in its interpretation of the law made them in many cases virtually the equivalent of judicial rulings. A few of the most important decisions of the commission may be mentioned here. Construing the long and short haul clause, they held that, in case of complaint for violating this section of the act, "the burden of proof is on the carrier to justify any departure from the general rule described by the statute, by showing that the circumstances and conditions are substantially dissimilar." They also decided that "when a greater charge in the aggregate is made for the transportation of passengers or the like kind of property for a shorter than a longer distance over the same line in the same direction, the shorter being included in the longer distance, it is not sufficient justification therefor that the traffic which is subjected to such greater charge is way or local traffic and that which is given the more favorable rates is not; and that it is not "sufficient justification for such greater charge that the short-haul traffic is more expensive to the carrier, unless when the circumstances are such as to make it exceptionally excessive, or the long-haul traffic exceptionally inexpensive, the difference being extraordinary and susceptible of definite proof; nor that the lesser charge on the longer haul has for its motive the encouragement of manufactures or some other branch of industry, nor that it is designed to build up business or trade centers."
