Procedures for the selection of SNB members are laid down by the national transposition laws of the Member State in which the given member is to be elected. These procedures may differ in each Member State. It is highly advisable that each elected member of the SNB present the SNB with proof of a lawful mandate (for example, protocol of the elections).

The SNB must have a minimum of three and may have a maximum number of members equal to the number of Member States in which a company is active (recent technical amendment of the EWC Directive adopted on 20 November 2006 by the European Commission, COUNCIL DIRECTIVE 2006/109/EC), in respect of the fact that:

i) each Member State in which a company has a subsidiary must have at least one member, and

ii) there are supplementary members in proportion to the number of employees working in the establishments within one country of operations.

It is obligatory to inform the central and local management about the composition of the SNB.
