After the expiration of the period specified in a declaration under section 183(5)(c) the trade union may present a further complaint to the Central Arbitration Committee that the employer has failed to disclose or, as the case may be, to confirm in writing to representatives of the union information specified in the declaration.
On receipt of a further complaint the Committee shall proceed to hear and determine the complaint and shall make a declaration stating whether they find the complaint well-founded, wholly or in part, and stating the reasons for their finding.
On the hearing of a further complaint any person who the Committee consider has a proper interest in that complaint shall be entitled to be heard by the Committee, but a failure to accord a hearing to a person other than the trade union and employer directly concerned shall not affect the validity of any decision of the Committee in those proceedings.
If the Committee find the further complaint wholly or partly well-founded the declaration shall specify the information in respect of which the Committee find that that complaint is well-founded.
