Every such agreement of merger or consolidation with such certificate of the secretaries and the tentative approval of the Commissioner of Banking and Insurance indorsed thereon shall be filed in the office of the Commissioner of Banking and Insurance and at the expiration of 30 days thereafter the commissioner shall indorse his final approval thereon unless within said 30 days, 5% or more of the member policyholders shall file with the commissioner objections to such agreement, in which case the commissioner shall call a hearing thereon and shall cause not less than 10 days' notice thereof to be given to such objectors and to each corporation to the agreement.

The commissioner's disapproval of such agreement shall be subject to review, hearing and relief in the Superior Court.
