leif – the O/C of which you’re a part by the way, CAN decide to remove the sound-blocking feature, and even to not maintain something at all provided ≥75% of those owners who bother to attend an AGM vote to do so, but ONLY if that doesn’t affect the security of the building, the structure of the building, the appearance of the building, or the appearance (and possibly therefore the value) of any Unit within it.
So NO, I’m afraid that a properly made decision to do that doesn’t require your approval, BUT you can have your say and vote (against) at the AGM, and seek the assistance of the NCAT to overturn any decision that wasn’t properly made (i.e. by Special Resolution) and to ensure that items of Common Property like the entrance lights, garden lights, and door locks are properly maintained.
It’s a pity that there apparently aren’t enough Owners who feel as you do, and who are prepared to either attend the AGM or to give you their vote by proxy so that the votes of your Committee and their friends can be overcome. That’s not unusual though, and more’s the pity.
I don’t know how you can think that nothing can be achieved by insisting that the rules are adhered to and that further actions are a waste of every body’s time when you haven’t as yet tried what I and others have suggested!
You still have a couple of choices:
1) Write to your Strata Manager and E/C Secretary to demand that they comply with Sect 62(1) and (2) of the SCMA by properly maintaining items such as the lighting and door locks, and to advise them that if they don’t do so, then you’ll be seeking the assistance of the NCAT to ensure that they do, and;
that if they decided to not maintain anything that affects the security of the building, then you’ll also ask the NCAT to overturn that decision as it breaches Sect 62(3)(b)
OR
2) sell your Unit at a reduced profit and let somebody else worry about all this.
Sorry, but this topic has just about been flogged to death in my opinion, and I don’t think that I for one can assist you any further; good luck with whatever you decide to do.
