§ 101. Review by industrial board of appeals. 1. Except where otherwise prescribed by law, any person in interest or his duly authorized agent may petition the board for a review of the validity or reasonableness of any rule, regulation or order made by the commissioner under the provisions of this chapter. Such petition shall be filed with the board no later than sixty days after the issuance of such rule, regulation or order.

2. The petition shall be filed with the board in accordance with such rules as the board shall prescribe, and shall state the rule, regulation, or order proposed to be reviewed and in what respects it is claimed to be invalid or unreasonable. Any objections to the rule, regulation or order not raised in such appeal shall be deemed waived. The board may join in one proceeding all petitions alleging invalidity or unreasonableness of substantially similar rules, regulations or orders. Except as otherwise prescribed by any provision of this chapter or any other law, the filing of such petition may, in the discretion of the board, operate to stay all proceedings against the petitioner under such rule, regulation or order until the determination of such petition.

3. If the board finds that the rule, regulation or order, or any part thereof, is invalid or unreasonable it shall revoke, amend or modify the same.
