Section 75-76-125 - Motion requesting taking of additional evidence by commission; modification of decision or order by commission; standard of review; grounds for reversing decision or order of commission(1) The reviewing court may, upon motion therefor, order that additional evidence in the case be taken by the commission upon such terms and conditions as the court may deem just and proper. The motion must not be granted except upon a showing that the additional evidence is material and necessary and that sufficient reason existed for failure to present the evidence before the hearing examiner or the commission. The motion must be supported by an affidavit of the moving party or his counsel showing with particularity the materiality and necessity of the additional evidence and the reason why it was not introduced in the administrative hearing. Rebuttal evidence to the additional evidence must be permitted. In cases in which additional evidence is presented, the commission may modify its decisions and orders as the additional evidence may warrant and shall file with the reviewing court a transcript of the additional evidence together with any modifications of the decision and order, all of which become a part of the record on review.(2) The review must be conducted by the court sitting without a jury, and must not be a trial de novo but is confined to the record on review.(3) The reviewing court may affirm the decision and order of the commission, or it may remand the case for further proceedings or reverse the decision if the substantial rights of the petitioner have been prejudiced because the decision is: (a) In violation of constitutional provisions;(b) In excess of the statutory authority or jurisdiction of the commission;(c) Made upon unlawful procedure;(d) Unsupported by any evidence; or(e) Arbitrary or capricious or otherwise not in accordance with law.Laws, 1990 Ex Sess, ch. 45, § 63, eff. 6/29/1990.
