Once a member of an accountable authority has disclosed a material personal interest, the member must stay out of the meeting while the matter is considered and must not vote on it. The member may take part only under a written declaration by the responsible Minister (available only where the quorum would otherwise fail, the matter is urgent, or there is a compelling reason) or under a decision of the members without an interest that the member is not disqualified, recorded in the minutes.
