Except as provided in section 261E-12(g), the commission, upon complaint of any interested person or upon its own initiative at once and, if it so orders, without answer or other formal pleading by the interested carrier or carriers, but upon reasonable notice, may enter upon a hearing concerning the lawfulness of the rate, fare, or charge, or the rule or practice, and pending the hearing and decision the commission, may suspend the operation of the schedule and defer the use of the rate, fare, or charge, or the rule or practice, by delivering to the affected carrier or carriers not later than five days prior to the effective date of the schedule, a statement in writing of its reasons for the suspension. The commission shall have up to six months from the date of ordering a hearing to investigate the lawfulness of the rate, fare, or charge, to complete its investigation. If the commission fails to issue a final order within the six-month period then the changes proposed by the carrier shall go into effect. At any hearing involving a change in a rate, fare, charge, or classification, or in a rule or practice, the burden of proof shall be upon the carrier to show that the proposed changed rate, fare, charge, classification, rule, or practice is just and reasonable. In exercising its authority under this subsection and subsection (e), the commission shall consider the factors regarding reasonableness set forth in section 261E-12(e).
