AJP – the fact that your resident bully may be elected Chairman is of little consequence, as the holder of that position has no more authority than any other Member of the Executive Committee; no casting vote or any other privilege.
Furthermore, the Legislation requires that an Agenda be produced and distributed to all Owners at least 72 hours in advance of each Executive Committee Meeting, so Owners who regard any Motion/s as contentious may themselves attend the Meeting or >30% of them (by unit entitlement) can veto such Motion/s before they’re even discussed at a Meeting.
There are sufficient safeguards provided by the Legislation to stifle the activities of Executive Committee bullies – what’s that saying about all that is necessary for the triumph of evil is that good men do nothing? Perhaps you need to enlist the support of some good men (and women) in your Plan, and have them ready to do something whenever the bully is at work!
