I think this is a very loaded question.
And I’m not really sure what the complaint is.
If you have a triad of office bearers, it’s because the AGM, to which you were invited, decided by a majority vote to have a triad. Did you attend? Did you nominate yourself for a position?
It’s the EC’s duty to write the agenda for meetings, and it must include any motions which they (or you) have submitted beforehand.
It’s normal meeting procedure for the submitter of a motion to move it, and speak for it.
It’s the EC’s duty to write the minutes. If you disagree with what’s written, you can (speak and) vote against them at the next meeting.
All decisions are carried by a “block” of at least 50% of votes, so maybe the majority just thought the motions were a good idea or gave proxies to people they thought were doing a good job.
How about giving us a few examples of the decisions which were not in “the best interests of the owners”?
