(b) Any interested party notified of a determination may request a hearing within ten days after delivery in hand by the commissioner's authorized representative, or mailing of said notice, unless it is determined in accordance with procedures prescribed by the commissioner that the party had good cause for failing to request a hearing within such time. In no event shall good cause be considered if the party fails to request a hearing within thirty days after such delivery or mailing of said notice. If a hearing is so requested, the commissioner or his authorized representative, except when the alternative provided in subsection (d) is invoked, shall afford all interested parties a reasonable opportunity for a fair hearing before an impartial hearing officer designated by the commissioner. The manner in which disputed claims shall be presented, and the conduct of the hearings, shall be in accordance with chapter thirty A, and such other procedures as prescribed by the commissioner which are not inconsistent with chapter thirty A. Such procedures shall include provisions for the following:
(1) reasonable notice of the time and place of the hearing to all parties in order to permit adequate preparation;(2) notice of the issues to be considered thereat;(3) the right of representation by an agent, counsel, or advocate;(4) the right to produce evidence and offer testimony, examine and cross-examine witnesses; and(5) making available to a party, upon request and within a reasonable time prior to a hearing, written information and documents in the possession of the commissioner to the extent necessary for the proper presentation of its case. The decision of the commissioner or his authorized representative shall be based solely on the testimony, evidence, materials and issues introduced at the hearing. The commissioner or his authorized representative shall make every reasonable effort to give notice of such decision, together with the findings and reasons therefor, to the parties by mailing to each party at his last known address a copy of such decision, findings and reasons, within forty-five days after the date of request for hearing. Benefits shall be paid promptly or denied in accordance with such decision. Unless action is taken under section forty, the decision of the commissioner or his authorized representative shall be final on all questions of fact and law.
