(1) If an appointed person has a personal interest in a matter that is required to be disclosed under section 28:
(a) the appointed person must not take part in any deliberation or decision of the Board about the matter; and
(b) the appointed person must be disregarded for the purpose of constituting the quorum of the Board for the deliberation or decision; and
(c) the quorum for the deliberation or decision is a majority of persons entitled to participate in the deliberation or decision.
(2) However, a failure by the appointed person to disclose the interest in the matter does not, on its own, invalidate any decision of the Board about the matter.
