The appointment of the former Chairman was made correctly (in NSW), provided he held the proxy of an Owner that permitted him to attend the Meeting and to vote on all matters on the Agenda (including the one to receive nominations for and to elect the Executive Committee), and provided he was nominated for election to the Committee by another Owner present at the Meeting who was themselves not a nominee for election (so his daughter could not nominate him).
As for the identity of the Owners who granted the proxies, the Minutes of the Meeting must show all people in attendance both personally and by proxy from Owners, so your former Chairman should be listed there as ” (name) by proxy from the Owner of Lot – “.
