In the event that a Member of the Board of Directors departs from membership of the Board of Directors or from the legal entity he represents, then his membership of the Board of Directors shall terminate. In such case, the vacated membership of the Board of Directors shall be substituted by alternate members. In the event that the number of Members of Board of Directors falls under one half of the original number as a result of such vacations despite the appointment of alternate members, the Board of Directors or the Board of Auditors shall call for a General Assembly meeting. In the event that such a call is not made, upon application by a member, the local civil court shall call for a General Assembly.
