Section 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.
