62-79. Final orders and decisions; findings; service; compliance.
(a) All final orders and decisions of the Commission shall be sufficient in detail to enable the court on appeal to determine the controverted questions presented in the proceedings and shall include:
(1) Findings and conclusions and the reasons or bases therefor upon all the material issues of fact, law, or discretion presented in the record, and
(2) The appropriate rule, order, sanction, relief or statement of denial thereof.
(b) A copy of every final order or decision under the seal of the Commission shall be served in the manner prescribed by the Commission upon the person against whom it runs or his attorney and notice thereof shall be given to the other parties to the proceeding or their attorney. Such order shall take effect and become operative when issued unless otherwise designated therein and shall continue in force either for a period which may be designated therein or until changed or revoked by the Commission. If an order cannot, in the judgment of the Commission, be complied with within the time designated therein, the Commission may grant and prescribe such additional time as in its judgment is reasonably necessary to comply with the order, and may, on application and for good cause shown, extend the time for compliance fixed in its order.
