For any other committee that has this problem, I would start minuting breaches under a system where members are given a warning verbally but if they persist, they are named in the minutes as having breached the code of conduct.
First of all, you would make it an agenda item for a committee meeting – under a heading like “Breaches of strata committee code of conduct” – and get a majority to agree that in future breaches of the code of conduct will be treated this way.
At the very least, at the next AGM you can point out that a certain owner is disruptive at meetings and shouldn’t be re-elected.
