(1) A voter must cast a vote at a TSRA election by marking the ballot paper to show the order of the voter's preference for the candidates.
(2) A ballot paper is formal if, and only if:
(a) an authorised electoral officer is satisfied that it is an authentic ballot paper; and
(b) it indicates the voter's first preference for one, and only one, candidate; and
(c) it does not have any identifying mark on it.
(3) A ballot paper that is formal must be given effect according to the voter's intention so far as that intention is clear.
"identifying mark" means writing or another mark by which, in the opinion of
an authorised electoral officer, the voter can be identified, but does not
include writing or another mark placed on the ballot paper (whether or not in
contravention of any law) by a person involved in conducting the election.
