Sriram Pasricha vs Jagannath & Ors on 24 August, 1976. reported in : 1976 AIR 2335 refers:
that all persons who purchases apartment in a group housing are automatic members of the apartment owners association. Therefore, there can be more than one member from one flat depending upon the number of owners the flat has.
As per the law settled by the Hon’ble Supreme Court any of the co-owner can cast its vote
there is no legal provision which determines who among co-owners shall vote. Therefore, it can be any co-owner against whose name other co-owner(s) have given no-objection either expressly or impliedly. It is advisable that the co-owner desiring to vote or put forward their candidature must give his name before the publication of final voters list by the election officer. A valid voter has the right to contest.
However, in case of co-operative group housing societies, the situation is a little rigid as the voting right is fixed in the name of the co-owner whose name stands first in the share-certificate issued by the co-operative society. But if the co-operative society does not issue share certificate than this rule shall not apply.
in a builder developed group housing a co-owner has right to cast vote and contest for the post in the board of management if remaining co-owner(s) have no objection, either expressly or impliedly. It is immaterial whether the name of the co-owners is mentioned at first, second or at any serial in the list of owners in the conveyance deed.
