SEC. 19. Unlawful acts.—It shall be unlawful for any public service: To provide or maintain any service that is unsafe, improper, or inadequate, or withhold or refuse any service which can reasonably be demanded and furnished, as found and determined by the Commission in a final order which shall be conclusive and shall take effect in accordance with this Act, upon appeal or otherwise. To make or give, directly or indirectly, by itself or through its agents, attorneys or brokers, or any of them, discounts or rebates on authorized rates, or grant credit for the payment of freight charges, or any undue or unreasonable preference or advantage to any person or corporation or to any locality or to any particular description of traffic or service, or subject any particular person or corporation or locality or any particular description of traffic to any prejudice or disadvantage in any respect whatsoever; to adopt, maintain, or enforce any regulation, practice or measurement which shall be found or determined by the Commission to be unjust, unreasonable, unduly preferential or unjustly discriminatory, in a final order which shall be conclusive and shall take effect in accordance with the provisions of this Act, upon appeal or otherwise. To refuse or neglect, when requested by the Director of Posts or his authorized representative, to carry public mail on the regular trips of any public land transportation service maintained or operated by any such public service, upon such terms and conditions and for a consideration in such amount as may be agreed upon between the Director of Posts and the public service carrier or fixed by the Commission in the absence of an agreement between the Director of Posts and the carrier. In case the Director of Posts and the public service carrier are unable to agree on the amount of the compensation to be paid for the carriage of the mail, the Director of Posts shall forthwith request the Commission to fix a just and reasonable compensation for such carriage and the same shall be promptly fixed by the Commission in accordance with section sixteen of this Act.
