Only the owners corp can, the committee can’t and if they that is something HH could raise. However, if no one is in the meeting and they have the proxies I suppose by default then they hold the power.
That’s how it works in most schemes that have this problem. The committee rocks up at the AGM, proxies and nominations in hand. They set the agendas and dominate the meetings and eventually other owners don’t even bother to show up,
They often use their exclusive access to owners’ email addresses and committee minutes to push their agendas and undermine attempts to change anything.
This can include listing the committee members who are in place and who will be standing again, in the agenda for the upcoming AGMs.
Barring something disastrous occurring financially, most other owners will lose interest and just leave things the way they are. This is so commonplace that the government had to change the rules on quorums for AGMs just so they could go ahead.
