As a very cynical exercise, you can set the size of the EC at your AGM and then decide who is and isn’t on it.
You can also demand that every contentious decision at a general meeting be decided by a poll vote (based on unit entitlements).
But be prepared to be the most hated person in the building if you throw your weight around in this way.
But you can’t alter common property without the support of another 10 percent of owners (giving you 75 percent) and you must have a properly constituted AGM every year at which certain items must be on the agenda.
But as far as running the EC is concerned, it depends how unpopular you are prepared to make yourself. It’s one person, one vote on the EC – unit entitlements don’t count – and you would have to hold a general meeting to overturn any decisions that you didn’t like.
As Whale says, use your power responsibly because there are ways too many poor decisions could come back to bite you on the bum. Not least among them is that another owner could successfully apply for the statutory appointment of a strata manager at which point you would find you had exactly the same power as other owners – ZERO.
