193.Section 57 provides that the commissioner is to be returned under the simple majority system unless there are three or more candidates, in which case the provisions of Schedule 9 provide for the supplementary voting system. A supplementary vote in this context means a vote capable of being given to indicate first and second preferences from among the candidates. Schedule 9 provides in paragraph 3 for the counting process where a candidate has an overall majority of first preference votes, and paragraph 4 where no candidate has such an overall majority.
