2.The suit has been laid by the deceased first plaintiff for declaration and permanent injunction. Pending suit, the first plaintiff died and his legal heirs namely, the plaintiffs 2 to 6 were brought on record. The plaintiffs claim title over the suit property based upon the Sale Deed dated 28.12.1990 executed by one Gajendran. The certified copy of the above said Sale Deed has been marked as Ex.A2. Further, according to the plaintiffs, Gajendran purchased the suit property from Ekambaram, the second defendant under the Sale Deed dated 27.05.1988. The certified copy of the above said Sale Deed has been marked as Ex.A7.
