43. Every member of the Council present at a sitting has one vote and must vote on all questions put to a vote. However, no member of the Council may take part in any deliberations nor vote on a question in which he has a personal interest, but he must disclose his interest to the meeting.
In the case of dispute, the Council decides whether the member has a personal interest in the matter, and such member shall not vote on the question of whether or not he is interested.
