I’d just ask your questions now. You don’t need to wait for a general meeting. You can ask your committee a question any time.
If you don’t like their answer and if the matter can be put in the form of a motion then you could do that. Most meeting rules would require that you give notice so it can be included in the meeting papers distributed with the notice of the meeting. Your motion should be seconded by someone, ideally someone you have appointed as your proxy for the meeting.
If it really is a matter for discussion only, then I think your proxy has to be ready to speak on the matter. Our AGM agenda routinely has an ‘Other Business’ item which is divided into two parts, 1) Discussion of matters notified to the managing agent before (some date), and 2) Discussion of any other matters, if time permits.
I.e. The chair can exercise some discretion about whether to allow the meeting to hear someone raising a matter that was not notified but any notified matter gets a hearing. NB. ‘Other Business’ should only be discussion. At most the minutes might record that the ‘mood of the meeting largely supported (some view)’. This is because the meeting can only pass resolutions on notified motions.
