This is a very good example of how a statutorily appointed manager can be a double edged sword. While owners corps can, to some extent, pay fast and loose with their responsibilities, Strata Managers have a legal responsibility to do the right thing and therefore tend to err on the side of over-servicing rather than under-servicing. And remember, things haven’t been done properly or they wouldn’t be there so they know that there is a level of scrutiny.
Your best if not only hope is for you and your neighbours to present a united front at the CTTT. If you can’t do that, the CTTT would be very unlikely to remove the order since the fundamental problem clearly still exists.
