The reviewing court may, upon motion therefor, order that additional evidence in the matter be taken by the Commission upon such terms and conditions as the court may deem just and proper. Such motion shall not be granted except upon a showing that the additional evidence is material and necessary and that sufficient reason existed for failure to present such evidence at the hearing of the Commission. The motion shall be supported by an affidavit of the moving party or his or her 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 shall be permitted. In matters in which additional evidence is presented to the Commission, 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 shall become a part of the record on review.
