Sectional title.Blocking someone from becoming a trustee

[RonSwanson]

OP, it's easy to get rid of a chair, not so easy for a trustee. Even if behind in levies, they can still be a trustee, but may not vote on resolutions, at least for 67 days.

As per Paddocks:

A trustee will be disqualified from holding office if they resign, becomes of unsound mind, is declared insolvent or is sequestrated, is convicted of an offence involving dishonesty, removed by ordinary resolution of the members at a general meeting, is in arrears for more than 60 days with any levies and contributions and has failed to settle the arrears following a 7 day notice period. If a trustee is disqualified or removed from office in one of these ways, the body corporate may, in terms of PMR 14, and at a general meeting, appoint another trustee for the unexpired portion of the term, until the next AGM.

Your idea of presenting reasons why the person's nomination as a trustee cannot be accepted at the AGM is one that might fly, so long as you have sufficient votes in favour of the motion. To get that, you need to do your homework and have enough reasonable and substantiated evidence to present in order to allow for an ordinary resolution to take place. The chair of the AGM may also not allow it if it is not on the agenda, or if it takes up too much time. And here's the clincher: As per PMR 18(1) of the Regulations the current chairperson chairs the AGM, unless the BC members present resolve otherwise.

Good luck, let us know how it went?
