A casual vacancy shall arise in the event of the death, disqualification of a Trustee, or vacation of office by a Trustee, before the end of that Trustee’s term of office as specified in accordance with article 6 (or as the case may be article 5), or the failure of a Trustee to make a declaration under article 7.

A casual vacancy arising in the office of a Trustee shall be filled by the appointment of a Trustee by the other Trustees.

A Trustee appointed to fill a casual vacancy under this article shall hold office (unless that person previously dies or otherwise ceases to be a Trustee) during the remainder of the term for which the Trustee who is replaced was appointed.
