If you are a clear majority and you are a small enough group to be able to readily communicate with each other I think you could issue a notice of a general meeting yourselves. You would need to have contact details for all owners to issue the notice. If you make sure that you do everything by the book I can’t see who could restrain an owners corporation from meeting.
We (our EC) recently called a meeting in the more usual manner to put a series of motions on an urgent and necessary matter and one extra matter that was not strictly necessary but a majority wanted to do it and it had to be done now if we were going to. An owners who has long campaigned against the second of those and refused to accept our legal advice on the first of those went to ACAT (the ACT Tribunal) seeking orders to declare each of the motions invalid and for orders to cancel the meeting.
The ACAT called an urgent hearing two days before our scheduled meeting date. This sort of behaviour has gone beyond a joke. We did not want to put up with this sort of sabotage and we engaged a lawyer to represent the owners corporation, the same lawyer who had assisted us in drawing up the necessary motions for the meeting. The meeting proceeded and the lawyer tweeted afterwards: “Just won a tribunal hearing in ACT so a meeting an (sic) proceed this week – courts don’t like restraining meetings – it’s jumping the gun”
So, if you tried before the conventional route to call a meeting and now a majority of owners put their names to a meeting notice, I doubt you could be be in trouble and I expect the decisions of the meeting would be valid if proper notice was given to all owners and proper minutes taken and distributed in the correct time frame and so on.
If you can afford proper legal advice though it would be worth it.
