Sec. 7. (a) Upon determination of the appeal, the court shall have jurisdiction to affirm or set aside such decision, ruling, or order of the commission, in whole or in part, or remand the proceeding to the commission with instructions. No evidence beyond that contained in the record of the proceedings before the commission shall be considered or received by the court, except that in cases where issues of confiscation or of constitutional right are involved, the court, on its own motion or verified petition of a party, may order such additional evidence as it deems necessary for the determination of such issues to be taken before the commission and to be received at the hearing before the commission in such manner and upon such terms and conditions as the court shall order.(b) If a new hearing is ordered under subsection (a), the commission is not required to receive any evidence as to facts which were in existence at the time of the prior commission hearing or hearings, except upon a showing, either to the court in the first instance, or the commission, upon the hearing, that:(1) the evidence was not available for presentation to the commission prior to the entry of its final decision, ruling, or order, or prior to the determination of the commission upon the petition for rehearing, if a petition for rehearing was filed; and(2) due diligence was exercised by the party offering the evidence to procure and present the evidence to the commission prior to the entry of its final decision, ruling, or order, or its determination upon the petition for rehearing, if any was filed.(c) Whenever the court shall order additional evidence to be taken the commission shall promptly hear and report the evidence to the court so that the proof may be brought as nearly as reasonably possible down to the date of its report to the court. The commission may, after hearing such evidence, modify its findings as to facts and its original decision, ruling, or order, and it shall file with the court the amended decision or orders and any modified or new findings.(d) If the commission modifies or amends its original decision or orders, the appealing party or any other party aggrieved by the modified or amended decision or order may file with the court, within the time allowed by the court, a specification of any errors of law claimed to have been made by the commission in the modified decision or orders. A specification of errors shall be considered by the court in addition to the errors of law asserted in the assignment or assignments of error.(e) The supreme court and the court of appeals, as the case may be, have jurisdiction, upon application of the commission or any party, to order or enjoin temporarily or permanently the enforcement of any determination, ruling, or order of the commission made in the cause.(f) The supreme court and the court of appeals, as the case may be, also have jurisdiction upon application of a public utility to issue temporary injunctions protecting the utility in the collection of rates determined by the court to be nonconfiscatory during the pendency of the proceeding and until nonconfiscatory rates are fixed by the commission if existing rates are finally determined to be confiscatory, with appropriate provisions as to bonds and refunds.Formerly: Acts 1957, c.189, s.7.
