which the p1amtiff seeks to enforce. That expression includes the cause of action and the relief claimed. Unless the cause of action and the relief claimed in the second suit are the same as in the first suit, it cannot be said that the subject-matter of the second suit is the same as that in the previous suit. Now coming to the case before us in the first suit Dr. Madan Lal was seeking to enforce his right to partition and separate possession. In the present suit he seeks to get possession of the suit properties from a trespasser on the basis of his title: In the first suit the cause of action was the division of status between Dr. Madan Lal and his adoptive father and the relief claimed was the conversion of joint possession into separate possession. In the present suit the plaintiff is seeking possession of the suit properties from a trespasser. In the first case his cause of action arose on the day he got separated from his family. In the present suit the cause of action, namely, the series of transactions which formed the basis of his title to the suit properties, arose on the death of his adoptive father and mother. It is true that both in the previous suit as· well as in the present suit the factwn and validity of adoption of Dr. Madan Lal came up for decision. But that adoption was not the cause of action in the first nor is it the cause of action in- the present suit. It was merely an antecedent even which conferred certain rights on him. Mere identity of some of the issues in the two suits does not bring about an identity of the subject matter in the two suits. As observed in Rakhma Bai v. Mahadeo Narayan('), the expression "subject matter" in Order 23, Rule 1, Code of Civil Pro· cedure means the series of acts or transactions alleged to exist giV:ing rise to the relief claimed. In other words "subject matter" means the bundle of facts which have to be proved in order to entitle the plaintiff to the relief claimed by him, We accept as ·correct the observations of Wallis C.J. in Singa Reddi v. Subba Reddi(2), that where the cause of action and the· relief claimed in the second suit are not the same as the cause of action and the mlief claimed in the fir't suit, the second suit cannot be considered to have been broaght in respect of the same subject matter as the first suit.
