Has something else gone on here, that you haven’t mentioned?
Either way, this bully needs to pull his head in. He can’t deny you access to common property, his by-law shouldn’t even be registered (if your strata manager is even barely competent) as it is harsh and discriminatory and unconscionable.
And you don’t have to put up with this. I wouldn’t even start with the various infractions of strata law. Apply to NCAT for the statutory appointment of a strata manager to take over all the duties and responsibilities of the committee and officebearers for the next two years on the grounds that the scheme is dysfunctional.
At the same time apply for a personal AVO on the grounds of racial and personal abuse and threats of violence, and ask that this knuckle-dragger be forbidden from talking to you or your partner or even discussing your conflict with neighbours.
Nibbling around the edges never works with these psychos although I can guarantee that even if you get a statutory manager and AVO, which will bring some relief for the next year or so, he will come back bad as ever when their time runs out.
