… from the facts you stated it’s unlikely thst the resolution was legally passed.
I’m afraid I disagree. A motion to seek council approval for work is not the same as a motion to commence the work. The council’s approval doesn’t mean that the work will be done, just that it can be done. There’s a big difference.
Obviously the majority of owners intend for the work to go ahead but they still require a special resolution and they simply don’t have the votes to achieve that.
