The other tactic that one strata manager uses is to hold committee and general meetings off site ie in his office. When the troublemaker starts trouble, the strata manager gives a warning and the next outburst uninvites the troublemaker from the premises.
It sounds like a good idea, but I can imagine a serial pest (rather than Shouty Angryman at a meeting) might then launch an action at NCAT that they had been deprived of their right to attend a meeting.
I’m not saying they’re right, just that if people are determined to make nuisance of themselves using spurious complaints then this would be grist to their mill.
Interested in the behaviour by-law. What’s the actual wording?
