In order to ensure a broad level of support for the natureplus Seal of Quality, all groups who are involved in the building process or affected by it, are represented within the Associations structure. This representation is also reflected in the twelve member executive committee.
The executive committee members are elected for a two year period by the membership general assembly. Re-elections are possible. The executive committee members elect the chairman, the vice-chairman and the treasurer. The chairman and vice-chairman are both individually empowered to represent the Association in all circumstances, in or out of a court of law.
Details of the regulations relating to the executive committee can be found in the Constitution under § 9.
