the Privy Council observed as follows: "That the right and its infringement, and not the ground or origin of the right and its infringement, constitute the cause of action, buy the cause of action for the Oudh suit (No. 8 of 1928) so far as the Mahbub brothers are concerned was only a denial of title by them as that suit was mainly against Abadi Begum for possession of the Oudh property; whilst in the present suit the cause, of action was wrongful 861 possession by the Mahbub brothers of the Shahjahanpur property, and that the two causes of action were thus different." "Their Lordships are satisfied that there is no force in the contention that the plaintiffs in the present suit could not reasonably commence an action in respect of the Shahjahanpur property while their right to mutation in the Revenue registers was the subject of an appeal to the Commissioner which had not been decided, or, in other words, that it was not open to them to sue the defendants in respect of the Shahjahanpur property at a date earlier than October 29, 1928 and to include the Shahjahanpur property in the earlier suit No. 8 instituted on September 14, 1928".
