My point was meant to note that many laws, including strata laws and regulations, can also apply to “occupiers”.
Yes, I got that, and it’s true. But it’s also possible that the owner simply wants it so his mother can visit (very frequently, you’d think), and I don’t think guests are considered to be the same as occupiers.
Either way, as I said, what lies at the heart of this problem is information, or the lack thereof. I think the OP is entitled to rev up the only other owner he needs to block the vote until everyone has sufficient reliable information on which to judge the issue.
