The Jumma Masjid, Mercara Vs Kodimaniandra Deviah AIR 1962 SC 847

Transfer of Property Act - Sections 6, 43 and 44
Hon'ble Supreme Court of India observed, “The sole point for determination in this appeal is, whether a transfer of property for consideration made by a person who represents that he has a present and transferable interest therein, while he possesses, in fact, only a spes successionis, is within the protection of s. 43 of the Transfer of Property Act. If it is, then on the facts found by the courts below, the title of the respondents under Ex. III and Ex. IV must prevail over that of the appellant under Ex. A. If it is not, then the appellant succeeds on the basis of Ex. A.…
whenever a person transfers property to which he has no title on a representation that he has a present and transferable interest therein, and acting on that representation, the transferee takes a transfer for consideration. When these conditions are satisfied, the section enacts that if the transferor subsequently acquires the property, the transferee becomes entitled to it, if the transfer has not meantime been thrown up or cancelled and is subsisting. There is an exception in favour of transferees for consideration in good faith and without notice of the rights under the prior transfer. But apart from that, the section is absolute and unqualified in its operation. It applies to all transfers which fulfil the conditions prescribed therein, and it makes no difference in its application, whether the defect of title in the transferor arises by reason of his having no interest whatsoever in the property, or of his interest therein being that of an expectant heir….
Section 43 deals with representations as to title made by a transferor who had no title at the time of transfer, and provides that the transfer shall fasten itself on the title which the transferor subsequently acquires. Section 6(a) enacts a rule of substantive law, while s. 43 enacts a rule of estoppel which is one of evidence. The two provisions operate on different fields, and under different conditions, and we see no ground for reading a conflict between them or for cutting down the ambit of the one by reference to the other. In out opinion, both of them can be given full effect on their own terms, in their respective spheres. To hold that transfers by persons who have only a spes successionis at the date of transfer are not within the protection afforded by s. 43 would destroy its utility to a large extent….
when a person transfers property representing that he has a present interest therein, whereas he has, in fact, only a spes successionis, the transferee is entitled to the benefit of s. 43, if he has taken the transfer on the faith of that representation and for consideration. In the present case, Santhappa, the vendor in Ex. III, represented that he was entitled to the property in praesenti, and it has been found that the purchaser entered into the transaction acting on that representation. He therefor acquired title to the properties under s. 44 of the Transfer of Property Act.”
