Although I can’t find this spelled out anywhere, it’s pretty clear that poll voting is not permitted at executive committee meetings in the ACT (or anywhere else for that matter).
This is what Schedule 2 of the Unit Titles legislation says:
2.10 Voting of executive committee
(1) At meetings of an executive committee, all matters must be decided by a majority of the votes of the executive members present and voting.
(2) If an executive committee has only 2 members, all matters must be decided by unanimous vote.
The clue is in the second section. If poll votes were allowed, then they would be the deciding factor in committees with only two members
Also, further on, Schedule 2 refers to the chair having the deciding vote in cases when there is a tied vote. Again, there is no mention of poll voting.
It’s one committee member, one vote – as it should be and is everywhere else in Australia.
