schedule item No.7, it was contended by the first defendant in the said suit that though the same is the property obtained by the deceased husband of the fifth defendant in his name, it is actually a property obtained by him along with Madhaven, and Vasudevan, another brother, and therefore, he is entitled to 1/3rd share in the said property on that basis. That suit was decreed in part by the trial court. The plaintiff therein, namely, the first defendant took up the matter in appeal and the appellate court modified the decision of the trial court and decreed the suit as prayed for. Though a third party challenged the decision of the appellate court before this Court, the second appeal preferred in this connection was dismissed by this Court. According to the plaintiff, his father was a person of unsound mind at the time when O.S.No 12 of 1965 was instituted and that the decision in the said suit is vitiated by fraud and collusion. The suit, in the circumstances, was for setting aside the decree in O.S. No 12 of 1965 and for partition of the properties described in plaint schedule item numbers 1, 6 and 7 and also for a declaration of his title and possession over the properties included in plaint schedule item Nos. 2, 3 and 4.
