SECTION 15. That the Commission is authorized and empowered, and it shall be its duty, whenever, after full hearing upon a complaint made as provided in section thirteen of this Act, or upon complaint of any common carrier, it shall be the opinion that any of the rates, or charges whatsoever, demanded, charged, or collected by any common carrier or carriers, subject to the provisions of this Act, for the transportation of persons or property as defined in the first section of this Act, or that any regulations or practices whatsoever of such carrier or carriers affecting such rates are unjust or unreasonable, or unjustly discriminatory, or unduly preferential or prejudicial, or otherwise in violation of any of the provisions of this Act, to determine and prescribe what will be the just and reasonable rate or rates, charge or charges, to be thereafter observed in such case as the maximum to be charged; and what regulation or practice in respect to such transportation is just, fair, and reasonable to be thereafter followed; and to make an order that the carrier shall cease and desist from such violation, to the extent to which the Commission shall find the same to exist, and shall not thereafter publish, demand, or collect any rate or charge for such transportation in excess of the maximum rate or charge so prescibed, and shall conform to the regulation or practice so pre-scribed. All orders of the Commission, except orders for the payment of money, shall take effect within such reasonable time, not less than thirty days, and shall continue in force for such period of time, not exceeding two years, as shall be prescribed in the order of the Commission, unless the same shall be suspended or modified or set aside by the Commission or be suspended or set aside by a court of competent jurisdiction. Whenever the carrier or carriers, in obedience to such order of the Commission or otherwise, in respect to joint rates, fares, or charges, shall fail to agree among themselves upon the apportionment or division thereof, the Commission may after hearing make a supplemental order prescribing the just and reasonable proportion of such joint rate to be received by each carrier party thereto, which order shall take effect as a part of the original order.

The Commission may also, after hearing of a complaint, establish through routes and joint rates as the maximum to be charged and prescribe the division of such rates as hereinbefore provided, and the terms and conditions under which such through routes shall be operated, when that may be necessary to give effect to any provision of this Act, and the carriers complained of have refused or neglected to voluntarily establish such through routes and joint rates, provided no reasonable or satisfactory through route exists, and this provision shall apply when one of the connecting carriers is a water line.

If the owner of property transported under this Act directly or indirectly renders any service connected with such transportation, or furnishes any instrumentality used therein, the charge and allowance therefor shall be no more than is just and reasonable, and the Commission may, after hearing on a complaint, determine what is a reasonable charge as the maximum to be paid by the carrier or carriers for the service so rendered or for the use of the instrumentality so furnished, and fix the same by appropriate order, which order shall have the same force and effect and be enforced in like manner as the orders above provided for in this section.

The foregoing enumeration of powers shall not exclude any power which the Commission would otherwise have in the making of an order under the provisions of this Act.

[Section 15. That if in any case in which an investigation shall be made by said Commission it shall be made to appear to the satisfaction of the Commission, either by the testimony of witnesses or other evidence, that anything has been done or omitted to be done in violation of the provisions of this Act, or of any law cognizable by said Commission, by any common carrier, or that any injury or damage has been sustained by the party or parties complaining, or by other parties aggrieved in consequence of any such violation, it shall be the duty of the Commission to forthwith cause a copy of its report in respect thereto to be delivered to such common carrier, together with a notice to said common carrier to cease and desist from such violation, or to make reparation for the injury so found to have been done, or both, within a reasonable time, to be specified by the Commission; and if, within the time specified, it shall be made to appear to the Commission that such common carrier has ceased from 6uch violation of law, and has made reparation for the injury found to have been done, in compliance with the report and notice of the Commission, or to the satisfaction of the party complaining, a statement to that effect shall be entered of record by the Commission, and the said common carrier shall thereupon be relieved from further liability or penalty for such particular violation of law.]
