"(a) To give to the protest of a single shipper the effect of preventing the advance of any rate until the reasonableness of that advance was affirmatively determined by the commission, would establish a hard and fast rule of doubtful fairness to the railroads and questionable advantage to the public. "(b) Under existing conditions we are of the opinion that it would be unwise to adopt the arbitrary limitation which this bill proposes. "(c) If every proposed advance had to be investigated by the commission and officially sanctioned before it could take effect the number of cases to be considered would presumably be so great as to render this prompt disposition almost impossible. "(d) It is further to be observed that the passage of such a bill at this time would impose a burden upon the commission, which it should not be asked to undertake. "(e) In instances of justifiable increase all necessary delay resulting from probable volume of cases would work injustice to the carriers. "(f) Until conditions become more stable and the substantive operations of the act are more completely observed in railway tariffs and practices, we entertain the belief that a wider latitude of discretion on the part of carriers than this measure allows would be permitted. "(g) It is also suggested that the practical effect of a proposed amendment might be to prevent voluntary reductions of rates by the carriers. "(h) If no rate could be increased without the approval of the commission after affirmative showing by the carrier, it might happen that many reductions now voluntarily accorded would not be made." The nine reasons suggested by the commission why the original amendment offered to section 6 should not be adopted, fully sustain the committee in reporting the bill adversely, and to a great extent, fully justify the views which it has expressed in this report as influencing the actions of the committee in its adverse report upon the amendment proposed in the committee. The committee is unable to appreciate the force of the suggestion of the modification proposed to the original amendment, as in any way changing the principle embodied in it, or the practical results which would flow from its adoption. If the power was conferred upon the commission, when a rate was advanced, upon complaint to suspend the going into effect of that rate until a final hearing, every objection urged by the commission to the adoption of the bill, but the first two, would be applicable to the modification proposed by the commission to the original amendment.
