Housing society denying share certificates

Hi I am a resident and flat owner of a housing society at Ahmedabad. Recently our managing committee has started the process of distributing share certificates when i have gone and asked for mine they said that they will not issue it as i have a Chajja (temporary structure) in balcony which is against the society rules. I told them that Chajja is to safeguard from rain/sunlight and both the matters are entirely different. There are other members also with Chajja, I requested them to treat both the matters differently but they are not listening or even ready to understand. Sir need your kind advise as am left dejected. Are they right in doing so? Can they be this authoritative and deny the basic rights?
