Johnty – As I said before it’s NOT your ceiling, and if your Owners Corporation resolves to permit your upstairs neighbour to cut a hole in it, then it’s up to it to ensure that the ceiling is returned to its original state.
Frankly, I wouldn’t preempt a 75% vote in favour of your neighbour’s proposal at the General Meeting that’s yet to be convened, as right now I’m unconvinced about the validity of the respective units of entitlement that you quoted in your other post on that topic!
Can you update your post on that issue!
