The committee can’t say no without holding a meeting – and as you are a member you should have been informed of the meeting and given the opportunity to state your case.
Sounds like this is one of those ad hoc committees of two or three where the strata manager, chair and secretary just make decisions – totally against the regulations.
Submit your by-law and a letter requesting a decision as soon as possible to the secretary and the strata manager. They will inevitably tell you that you’ll need to wait until the next AGM, but if that’s too far away, inform them that you will be seeking orders under section 232 (and will do so anyway if it’s rejected at the meeting).
