In order to obtain the same number of representatives, on the one hand, of the trade union organisations and, on the other hand, of the professional organisations plus the representatives of the consular networks, the prefect may appoint additional representatives of a trade union or professional organisation. Depending on the case, the additional seats are allocated to the employees’ trade union organisations that obtained the best results in the audience measurement carried out in application of the provisions of Chapter II of Title II of Book I of Part Two or to the employers’ professional organisations whose audience measurement carried out in application of the provisions of Chapter II of Title V of Book I of Part Two is the most significant.
