(a) The commission shall cause to be made a complete record of all adjudicatory proceedings. Any party to the adjudicatory proceeding may inspect the record. Upon request, the commission shall furnish a copy of the record including exhibits and transcripts or any part thereof to any party, and the commission may charge that party not more than the commission’s cost for the preparation and furnishing of such record or transcript or any part thereof, or in the alternative, the commission may charge the rate specified in the commission’s contracts with a private hearing stenographer. A party also shall be entitled to obtain at such party’s own cost a copy of the transcript directly from the hearing stenographer.
(b) The commission shall maintain an index by name and subject of all written final decisions, determinations and orders rendered by the commission in adjudicatory proceedings. Such index and the text of any such written final decision, determination or order shall be available for public inspection and copying.
