round three points, namely, (1)Whether the security bond (exhibit E 1) executed by Rashmoni along with Mohini was executed for legal, necessity and was therefore binding on the reversioners, of Haripada after the death of Rashmoni ? (2)Whether the fact that Mohini, who was the presumptive reversioner at that time, joined with his mother in executing the security bond would make it binding on the ,actual reversioner after the death of Rashmomi? In ' any event if such consent on the part of the presumptive reversioner raised a presumption of legal necessity, was that presumption rebutted in the present case by the evidence adduced by the parties ? (3)Whether the title of defendant No. I was protected ,he being a stranger purchaser who had purchased the property from the purchaser at an execution sale after making proper enquiries and obtaining legal advice ? The trial Judge by his judgment dated the 22nd December, 1944, decided all these points in favour of the plaintiffs and decreed the suit.
