In Councils with alternate members and in Disciplinary Boards, the alternate members replace, where appropriate, the full members who are prevented from sitting or who cease to hold office for any reason whatsoever before the end of their term of office. In the latter case, the term of office of the alternate members shall be that remaining until the date on which the term of office of those whom they replace would have expired.
The vacant seat shall be filled immediately by the alternate member elected in the same ballot and having received the highest number of votes. In the event of a tie, the seat shall be filled by the oldest alternate member having obtained the same number of votes. Except in the case of members elected in a single-member constituency, the alternate member who replaces the full member shall be of the same gender as the full member.
The procedures for deputising on disciplinary boards and chambers may be specified by the associations in their internal rules.
