Article 54 Acting appointments

If a member of the Corporation is unable to perform the functions of his office by reason of illness, absence from the Territories, or any other cause, the authority by which that member was appointed may appoint any person, not being a person disqualified for appointment as a member, to act in his place; and any person so appointed shall, subject to the provisions of section 53, continue so to act until the expiration of such period as may be specified in his instrument of appointment or until that member resumes the performance of those functions, whichever is the earlier.
