Am I able to direct these complaints to our Property Manager and tell her we will not discuss these at the AGM? Can she legally just use our AGM as a whingingfest?
Who chairs the meeting? Do you have an elected chair? If the items aren’t on the agenda they shouldn’t be discussed. If they are, then you can tell her to pull her head in and maybe vote her out of her role (whatever it is). Your property manager may well tell you this is not in their scope of duties.
