If objections are filed with the commission, the commission shall cause a pre-hearing conference to be held between all parties, intervenors, and the commission staff in all cases involving more than one hundred thousand customers.
If objections are filed with the commission within thirty days after the filing of such report, the application shall be promptly set down for hearing of testimony before the commission or be forthwith referred to an attorney examiner designated by the commission to take all the testimony with respect to the application and objections which may be offered by any interested party. The commission shall also fix the time and place to take testimony giving ten days' written notice of such time and place to all parties. The taking of testimony shall commence on the date fixed in said notice and shall continue from day to day until completed. The attorney examiner may, upon good cause shown, grant continuances for not more than three days, excluding Saturdays, Sundays, and holidays. The commission may grant continuances for a longer period than three days upon its order for good cause shown. At any hearing involving rates or charges sought to be increased, the burden of proof to show that the increased rates or charges are just and reasonable shall be on the public utility.
When the taking of testimony is completed, a full and complete record of such testimony noting all objections made and exceptions taken by any party or counsel, shall be made, signed by the attorney examiner, and filed with the commission. Prior to the formal consideration of the application by the commission and the rendition of any order respecting the prayer of the application, a quorum of the commission shall consider the recommended opinion and order of the attorney examiner, in an open, formal, public proceeding in which an overview and explanation is presented orally. Thereafter, the commission shall make such order respecting the prayer of such application as seems just and reasonable to it.
In all proceedings before the commission in which the taking of testimony is required, except when heard by the commission, attorney examiners shall be assigned by the commission to take such testimony and fix the time and place therefor, and such testimony shall be taken in the manner prescribed in this section. All testimony shall be under oath or affirmation and taken down and transcribed by a reporter and made a part of the record in the case. The commission may hear the testimony or any part thereof in any case without having the same referred to an attorney examiner and may take additional testimony. Testimony shall be taken and a record made in accordance with such general rules as the commission prescribes and subject to such special instructions in any proceedings as it, by order, directs.
