Judgement M. ANANTANARAYANAN, C. J. : The case referred to us under Section 57 of the Indian Stamp Act involves this question whether a particular document is an instrument chargeable as a conveyance under Art. 23 of Schedule I (previous Art. 19 of Schedule 1-A) or as release under Art. 55 of Schedule I of the Indian Stamp Act. We have had the benefit of elaborate arguments on this matter, and, apart from the facts to which we shall presently refer, and which are explicit and clear, the question also involves the interpretation of what amounts to a release in law as distinguished from a conveyance or transfer of property for value; there are one or two leading authorities available on this aspect, to which also we shall make a brief reference. 2. In order to have a clear picture of the preceding facts, we might immediately take up the settlement deed dated 5-4-1955 which is among the papers and which involves one N.K. Patel and his two sons K.N. Patel (first son) and R.N. Patel (second son). Under this settlement deed, it is recited that there are certain immoveable properties, of which the settlor (N.K. Patel) and his first son (K.N. Patel) are co-owners and joint tenants, with a right of survivorship reserved to the surviving party. The settlor out of natural love and affection for the second son donee, makes this settlement of his undivided half share in the properties, the other co-owner (the first son) joining in the instrument as thereby, the right of survivorship comes to an end The document proceeds to state that the donee will thereafter hold the property along with the first son as tenants-in-common in equal shares. 3. The next document that we have to scrutinise is the document dated 12-7-1957, which is the instrument under analysis. This instrument refers to a mortgage dated 14-7-1955 and the releasee (first son) assigns this mortgage to the releasor (second son), which forms the element of consideration for the release itself. We need not further dwell on this aspect. The learned counsel for the State (Sri Ramaswami) does not contend that a release deed is valid only when it is gratuitous. Admittedly, a release deed can be validly executed also for some benefit accruing to the releasor simultaneously. We need not further dwell on this aspect. The learned counsel for the State (Sri Ramaswami) does not contend that a release deed is valid only when it is gratuitous. Admittedly, a release deed can be validly executed also for some benefit accruing to the releasor simultaneously. After having recited this the donee (second son) (releasor) purports to release his undivided half share and interest in the entire property, in favour of the first son (releasee). The document proceeded to state that the amount secured under the mortgage (Rs. 51,250) forms the consideration, in the sense that this half share itself is valued at about that figure. Admittedly, the entire estate was acquired for a much less amount several years earlier, and both the co-owners claim to have spent moneys on the estate, resulting in a considerable enhancement of its value. 4. The question that falls to be decided by us is whether this instrument must necessarily be construed as amounting to a conveyance, and assessed for stamp as such, or could be accepted as a release under Article 55 of Schedule I. If is not in dispute that the nomenclature is not decisive not the language which the parties may choose to employ, in framing the document. What is decisive is the actual character of the transaction, and the precise nature of the rights created by means of the instrument. 5. Of the several authorities that have been referred to before us, the decision of the Pull Bench in Board of Revenue v. Murugesa Mudaliar, 1955-2-Mad LJ 166, : (AIR 1955 Mad 641) (FB) would appear to be most relevant, and indeed, virtually decisive of the issue. There also the Full Bench was concerned with a transaction between co-owners, with regard to property under which these co-owners held undivided shares, and there had been no division by metes and bounds. The relevant canon was stated by Rajamannar C.J. in the following form :- "In such a case there need be no conveyance as such by one of the co-owners in favour of the other co-owners. Each co-owner in theory is entitled to enjoy the entire property in part and in whole. It is not therefore necessary for one of the co-owners to convey his interest to the other co-owners. It is sufficient if he releases his interest. Each co-owner in theory is entitled to enjoy the entire property in part and in whole. It is not therefore necessary for one of the co-owners to convey his interest to the other co-owners. It is sufficient if he releases his interest. The result of such a release would be enlargement of the share of the other co-owners. There can be no release by one person in favour of another who is not already entitled to the property as co-owner." 6. In the last paragraph of this decision, there is some reference to the parallel case of a Hindu coparcenary, where one member purports to relinquish his rights in the family property in favour of the remaining coparceners. The learned Judges finally proceeded to observe :- "We can see no difference in principle, between such a document as between members of a coparcenary and the document in question, which is a document between co-owners." Finally, the learned Judges held that the document was a release, not liable to be charged either as a deed of dissolution of partnership or as a conveyance. 7. Another very relevant decision is that of the Supreme Court in Kuppuswami Chettiar v. Arumuga Chettiar, C. A. No. 521 of 1964 : ( AIR 1967 SC 1395 ), (not reported in full text so far). Their Lordships were concerned with the nature of a document of release and they approbated the observations that ''a release deed can only feed title but cannot transfer title" and also that "renunciation must be in favour of a person who had already title to the estate, the effect of which is only to enlarge the right." Their Lordships further proceeded to observe, with great significance for the facts of the present case, that "it cannot be disputed that a release can be usefully employed as a form of conveyance by a person having some right or interest to another having a limited estate, e.g. by a remainderman to a tenant for life and the release then operates as an enlargement of the limited estate." 8. In the present case, prima facie, it may be contended with great force and plausibility that the document rightly purports to be a release, and should be received as such. In the present case, prima facie, it may be contended with great force and plausibility that the document rightly purports to be a release, and should be received as such. For it cannot be disputed, we think, that the estate in question is owned by two parties or co-owners, that the releasee has already an undivided half share in the estate and that what the releasor purports to do by the document is to effect himself, in respect of both this title and his right to possession in favour of the releasee Nevertheless, Sri Ramaswami for the State has contended, upon two main lines of reasoning, that the document has to be interpreted as a conveyance, or should be held essentially to be such. The first line of reasoning is based upon the distinction well known to law borrowed from the English law of real Property between a joint tenant and a tenant-in-common. This distinction has also been applied to the concept of a Hindu Coparcenary as existing before a division in status and the state of rights between erst-while co-parceners after division in status, as would be apparent from cited passages in Mulla's Hindu law. The other line of reasoning is that upon the actual phraseology of Article 55 of Schedule I such a document as this cannot amount to a release. 9. We have carefully examined these arguments, and we do not find them to be substantial. No doubt, there is a well understood distinction between tenancy in common and a joint tenancy, and our attention has been drawn to the relevant passage or entry in Jowitt's Dictionary on English law, page 1728. It is pointed out there :- "Tenancy in common differs from joint tenancy, in that joint tenants have one interest in the whole and no interest in any particular part. Tenants in common have several and distinct interests in their respective parts-tenants in common held by unity of possession, because neither of them knows his own severally." Our attention has also been drawn to one passage upon this aspect, setting forth an extract from Halsbury in State of Madras v. Subramania Iyer, 1965-1 Mad LJ 566, to which one of us was a party. 10. We do not think that this distinction is really significant on the present facts, and it need not be pressed very far in the present case. 10. We do not think that this distinction is really significant on the present facts, and it need not be pressed very far in the present case. To the extent of the present facts, these two parties are co-owners, with a title which cannot be demarcated or fixed, with reference to any particular part of the property. In other words, there is a joint possession that can only be severed by partition, and further commonalty of title, in the sense that the title of the releasor is derived from the father, who jointly held the property with the other son, the releasee. In that context, therefore, we do not think that the mere fact that these persons can be described in a certain sense as tenants in common would convert a document which purports to be a document of release, into a conveyance. 11. On the contrary, we may emphasise that the essential ingredients of release are here present. There is already a legal right in the property vested in the releasee, and the release operates to enlarge that right into an absolute title for the entire property, as far as the parties are concerned. 12. The next argument of the learned counsel that this kind of release does not fall within the ambit of Article 55 of Schedule I appears to be devoid of substance. Article 55 refers to release, that is to say "any instrument ......... whereby a person renounces a claim upon any other person, or against any specifies property." We do not think that this means that a releasor cannot validly state, in the instrument, that he is effacing his rights in the property, in favour of another named individual. There is an entity known to law as a document of release, and we have no reason to think that, by this Article that entity was not indicated but only one particular kind of sub-species release, wherein the person in whose favour the release is declared or intimated, is not designated by identity or name. 13. We would, therefore, unhesitatingly answer the question. In the form that the document was rightly interpreted as a release under Art 55 of Schedule I of the Indian Stamp Act and is liable to duty as such. Answer accordingly.
