Allotment of car parking

Dear Sir / Madam, I have purchased an apartment in chennai 12yrs ago and the building has 10 apartments in total. The builder has not alloted the car parking officially to owners for the past 12yrs and now he passed away. There were only 2 cars 12yrs ago but now slowly the number of cars increased and people started parking on their favorite and easy parking spaces. Now association wants to allocated car parking and the association gave good parkings to their friendly neighbours. The parking alloted for me is side wise parking where 3 parkings to be parked one behind the other and my parking is the middle one which is practically not possible to park a car. I am the first purchaser of apartment in my building and my apartment is the biggest apartment 3 bhk and i am paying the highest maintenance charges. The association is considering any of these and trying to allot a parking asper their wish. My question is 1. Can i stop the allotment of car parking by association legally. 2. The allotment of car parking by assocition is for their friendly people. Can i have fair allotment of car parking since i am having bigger flat and paying highest maintenance charges or by means of any other method kindly advice me sir. 3. Since there is no parking space alloted by builder can we have a fresh allotment. If so how to allot car parkings and on what basis. Thank you for your advice in advance sir.
