§ 36. Orders and service thereof. 1. If it be ascertained after an investigation or hearing conducted as herein provided, that any person, association or corporation has failed to comply with or is guilty of a violation of the provisions of this chapter or of a rule of the department, or of any other general or special law relative to any matter within the jurisdiction of the department, an order may be made by the commissioner, under the seal of the department, compelling a compliance with such law or rule.
2. Every such order shall be served upon every person, association or corporation affected thereby, either by personal delivery of a certified copy thereof, or by mailing a certified copy thereof with postage prepaid to the person affected thereby, or in case of a corporation or association, to an officer or agent thereof, upon whom a summons may be served in accordance with the provisions of the civil practice act.
3. It shall be the duty of the person, association or corporation upon whom such order is so served to notify the department forthwith, in writing, of the receipt of such order, and in the case of an association or corporation such notification must be signed and acknowledged by a person or officer duly authorized by such association or corporation to admit service. Within a time specified in the order, every person, association or corporation upon whom it is served must, if so required in the order, notify the department in like manner whether the terms of the order are accepted and will be obeyed.
4. Every such order shall take effect at a time therein specified, and shall continue in force either for a period to be designated therein or until changed or abrogated by the commissioner.
5. If such hearing is held before a deputy commissioner, a report shall be made upon the termination of the hearing to the commissioner, with recommendation as to the determination which should be made as to the issues raised on such hearing. If the commissioner find upon such report or upon a hearing conducted by him, that the rule or order complained of is reasonable and valid he shall render his decision ratifying or confirming such rule or order; if he find that such rule or order is unreasonable or invalid, he shall revoke or modify it, or substitute a new rule or order in its place. If such modified or new rule or order is substantially different from the rule or order complained of, the parties affected thereby may bring before the commissioner, by a new petition, in the manner above provided, objections to its reasonableness or validity.
6. The decision of the commissioner shall be final, unless within thirty days after its issuance one of the parties shall institute a proceeding for the review thereof, as provided in section thirty-seven.
