Does association have the power to disconnect the DG back up and Club house entry.

We are in Chennai staying in a apartment were we have 350+ flats are there. Initially we conduct the election to decide on which method we follow to collect the maintenance. In which 3 methods are announced and they are: Sqft, Hybrid & Flat. The result was in favors of Sqft method. However it was not accepted by few owners and the SGM was conducted in the very next month were the association advised every one to participate. In the last minute they said there will be a voting for finalize the maintenance collection method. Most of the members are unable to participate. However in the second time flat method has been rejected and only sqft & Hybrid method has been announced for voting. In the result Hybrid won the majority and it has been implemented. Now this time its not satisfied for us. After several opinion we had a discussion with association that the maintenance has to be collected with sq.ft basis not on any other basis. At the same time we are paying maintenance based on sq.ft till date. After 4 month no movement from association but suddenly they stopped the DG back up for people who all paid in sqft basis. Also they announced that these peoples are not allowed to enter the club house. Hence we sent a legal notice to them but not getting any response, meanwhile we are struggling with out DG back up during this summer season. Need legal advise to proceed further.
