The business and affairs of the Society are governed by its Management Board, which possesses all of the powers of the Society, and is elected by the General Meeting of Members among the Full Members. The Management Board comprises at least the President of the Board, the Treasurer, Secretary and Vice Chairman. The Management Board can add extra members as appropriate between General Meetings and these additions will be ratified at the next General Meeting.

The Management Board meets at least once every six months upon convocation by the Chairman of the Board. Decisions are taken by a simple majority of votes, except for decisions on the deprivation of membership which have to be taken by a 2/3 majority of votes. The Chairman of the Board has a deciding vote in case of even numbers of votes for or against a decision. Vote by proxy is possible. Each member in the Management Board can be represented if necessary by another member of the Board, with a limit of two such proxies. A quorum of four Directors, present or represented, is requested for all decisions of the Management Board. All meetings of the Management Board are minuted. The Management Board can hold virtual meetings by way of teleconference, videoconferences or other means.
