No. 19 of 1967	 66 of 1964 and 27 of 1972 respectively. B. Datta	 Additional Solicitor General	 M.B. Rao and Ms. A. Subhashini for the Appellant. Soli J. Sorabji	 Harish Salve	 Mrs. A.K. Verma and Jeel Peres for the Respondents. The Judgment of the Court was delivered by PATHAK	 CJ. The assessee is a Hindu Undivided Family deriving income from interest on securities	 dividends	 property and dealing in shares. In 1941 the assessee pur chased a share of the Shorrock Spinning and Manufacturing Co. Ltd.	 hereinafter referred to as 181 "the Shorrock Co."	 of the face value of Rs. 1	000 for Rs.3	307. Later this share was split into 10 shares of Rs. 100 each	 and from time to time a total of 80 shares of the face value of Rs. 100 each was issued to the assessee by way of bonus shares. In consequence	 on 31 December	 1959 the assessee owned 90 shares in the Shorrock Co. of the face value of Rs. 100 each. There is another company called the New Shorrock Spin ning and Manufacturing Co. Ltd. to which reference may be made as "the New Shorrock Co.". It was decided to amalgamate the Shorrock Co. with the New Shorrock Co.	 and upon peti tions filed under section 39 1 and section 394 of the the Gujarat High Court made an order dated 23 Septem ber	 1960 directing meetings of the share holders of both the companies. The meetings were held on 27 October	 1960 and the scheme of amalgamation was approved. On 25 November	 1960 the High Court sanctioned the scheme of amalgamation and declared that the scheme would be binding on members of both the Companies. Under the scheme of amalgamation	 the undertaking and all the property rights and powers as well as all liabili ties and duties of the Shorrock Co. were to stand trans ferred and vest with effect from 1 January	 1960 in the New Shorrock Co. The scheme of amalgamation provided further for an increase in the share capital of the New Shorrock Co. and it permitted the creation of 14	625 new ordinary shares of the face value of Rs. 125 each of the transferee company. The newly created shares were to rank pari passu with the existing shares of the transferee company in all respects. Under the scheme the New Shorrock Co.	 as the transferee company	 was directed to allot to members of the Shorrock Co.	 the transferor company	 one share in the transferee company for every two shares of the transferor company held by them. The order of the Court directed that the Shorrock Co. should file a certified copy of the order with the Registrar of Companies within 14 days for registration	 and on such certified copy being delivered the transferor compa ny would stand dissolved and the Registrar of Companies was to place all documents relating to the transferor company on the file relating to the transferee company and the folios relating to the two companies were to be consolidated ac cordingly. During the assessment proceedings for the assessment year 1961 62	 the previous year being the financial year ended 31 March	 1961	 the Income Tax Officer	 although apprised of the fact of the scheme of amalgamation and of the acquisition by the assessee of 45 shares of the 182 New Shorrock Co. omitted to consider the applicability of section 12B of the Indian Income Tax Act	 1922. On 21 January	 1964 the Commissioner of Income tax issued a notice under section 33B of the Act to the assessee stating that the receipt of 45 shares of the New Shorrock Co. "in exchange" of his original holding of 90 shares in the Shorrock Co. in December 1960 had resulted in an assessable profit	 and this aspect had been overlooked by the Income Tax Officer when making the regular assessment	 and	 therefore	 he proposed a revision of the assessment. After heating the assessee	 the Commis sioner of Income Tax passed an order dated 29 January	 1964 directing the Income Tax Officer to revise the assessment and to include an amount of Rs.49	350 representing the capital gain resulting from the transaction of the acquisi tion of 45 shares of New Shorrock Co. in place of the 90 shares held in Shorrock Co. On appeal by the assessee before the Income Tax Appellate Tribunal	 the Appellate Tribunal held that the transaction represented neither an exchange nor a relinquishment and	 therefore	 section 12B of the Act was not attracted. At the instance of the Revenue the Appel late Tribunal referred the following questions to the High Court for its opinion: "1. Whether on the facts and in the circumstances of the case	 the sum of Rs.49	350 could be assessed in the hands of the assessee as capital gains as having ac crued to the assessee by exchange or relin quishment as provided for under section 12B of the Act? 2. If the answer to the above question is in the affirmative	 whether the said sum of Rs.49	350 was assessable in the year 1961 62?" Before the High Court the Revenue did not contend that the transaction constituted a sale or a transfer	 and the parties confined themselves to the point whether the trans action represented an exchange or a relinquishment for the purposes of section 12B. The High Court took the view that no exchange can be said to have taken place on the allotment of the 45 shares of the New Shorrock Co. under the scheme of amalgamation. Nor	 in the opinion of the High Court	 did it constitute a relinquishment. In the result	 the High Court answered both questions in favour of the assessee and against the Revenue. The relevant portion of section 12B of the Act provides: 183 section 12B(1) Capital gains. The tax shall be payable by an assessee under the head "Capital gains" in respect of any profits or gains arising from the sale	 exchange	 relinquish ment or transfer of a capital asset effected after the 31st day of March	 1956	 and such profits and gains shall be deemed to be income of the previous year in which the sale	 ex change	 relinquishment or transfer took place. The sole question is whether the receipt of the 45 shares of the New Shorrock Co. upon amalgamation by reason of the share holding of 90 shares of the Shorrock Co. can be described as an "exchange" or a "relinquishment" within the meaning of section 12B of the Act. It seems plain to us that no exchange is involved in the transaction. An exchange in volves the transfer of property by one person to another and reciprocally the transfer of property by that other to the first person. There must be a mutual transfer of ownership of one thing for the ownership of another. In the present case	 the assessee cannot be said to have transferred any property to any one. When he was allotted the shares of the New Shorrock Co. he was entitled to such allotment because of his holding the 90 shares of Shorrock Co. The holding of the 90 shares in the Shorrock Co. was merely a qualifying condition entitling the assessee to the allotment of the 45 shares of the New Shorrock Co. The dissolution of the Shor rock Co. deprived the holding of the 90 shares of that company of all value. On the question whether there was any relinquishment	 the decision must again be against the Revenue. A relin quishment takes place when the owner withdraws himself from the property and abandons his rights thereto. It presumes that the property continues to exist after the relinquish ment. Upon amalgamation	 the shares of the Shorrock Co.	 as has been mentioned earlier	 lost all value as that company stood dissolved. There is no relinquishment. The connected cases raise similar questions	 and are dealt with accordingly. In the result	 we agree with the view taken by the High Court	 and dismiss these appeals with costs. H.L.C. Appeals dis missed.

Sub section (1) of section 12B of the Indian Income Tax Act	 1922 provides that tax shall be payable by an assessee under the head "Capital gains" in respect of any profits or gains arising from the sale	 exchange	 relinquishment or transfer of a capital asset. The respondent assessee who owned 90 shares in the Shorrock Co. which stood dissolved under a scheme of amalga mation with another company known as New Shorrock Co.	 which was sanctioned by the High Court	 was aborted 45 shares of the New Shorrock Co. in terms of the provisions of the said scheme. During the assessment proceedings for the assessment year 1961 62	 the Income Tax Officer omitted to consider the applicability of section 12B 10 the case of the assessee. Later on	 the Commissioner issued a notice under section 33B to the assessee stating that the receipt of 45 shares of the New Shorrock Co. "in exchange" of his original holding of 90 shares in the Shorrock Co. had resulted in an assessable profit	 and passed an order directing the Income Tax Officer to revise the assessment and to include an amount of Rs.49	350 representing the capital gain resulting from the transaction. On appeal by the assessee the Appellate Tribu nal held that the transaction represented neither an ex change nor a relinquishment and	 therefore	 section 12B of the Act was not attracted. However	 at the instance of the Revenue the Tribunal referred the question to the High Court which answered it in favour of the assessee. Dismissing the appeals	 180 HELD: The sole question is whether the receipt of the 45 shares of the New Shorrock Co. upon amalgamation by reason of the share holding of 90 shares of the Shorrock Co. can be described as an "exchange" or a "relinquishment" within the meaning of section 12B. It seems plain to us that no exchange is involved in the transaction. An exchange involves the trans fer of property by one person to another and reciprocally the transfer of property by that other to the first person. There must be a mutual transfer of ownership of one thing for the ownership of another. In the present case	 the assessee cannot be said to have transferred any property to any one. When he was allotted the shares of the New Shorrock Co. he was entitled to such allotment because of his holding the 90 shares of Shorrock Co. The holding of the 90 shares in the Shorrock Co. was merely a qualifying condition enti tling the assessee to the allotment of the 45 shares of the New Shorrock Co. The dissolution of the Shorrock Co. de prived the holding of the 90 shares of that company of all value. [183B E] On the question whether there was any relinquishment	 the decision must again be against the Revenue. A relin quishment takes place when the owner withdraws himself from the property and abandons his rights thereto. It presumes that the property continues to exist after the relinquish ment. Upon amalgamation	 the shares of the Shorrock Co. lost all value as that company stood dissolved. [183E F]
