JUDGMENT (Per T. D. Sugla, J.) By this petition under Article 226 of the Constitution of India, the petitioners, a registered partnership firm, have challenged the legality and validity of notice dated 21st March, 1984 issued under section 148 read with section 147(a) of the Income-tax Act, 1961 for the petitioners' assessment for the assessment year 1975-76. The assessment was originally completed under section 143(3) read with section 144-B on 30th December, 1977. This assessment was set aside by the CIT (Appeals), Bombay, by his order dated 24th March, 1979. Fresh assessment was completed under section 143(3) read with section 144-B on 24th September, 1981. Both in this and the original assessment, the assessees income under the head capital gains on sale of shares was computed at Rs. 69,09,658/-. This was on the basis of the assessees' statement as under :- Statement showing the basis of computation of capital gains in respect of shares of The Great Eastern Shipping Co. Ltd. -------------------------------------------------------------------------- Original Bonus Year How allotted Rate Total Cost Shares Shares -------------------------------------------------------------------------- 60 - 1953 - 10 600 ------------------------------------------------------------------------- 6549 - 1957 - 10 65,490 ------------------------------------------------------------------------- - 11,105 1952 - 10 1,11,050 ------------------------------------------------------------------------- - 11,762 1956 1 share for every 5 shares held 2 23,524 ------------------------------------------------------------------------- - 36,249 1965 1 share for every 3 shares held 3 1,08,747 ------------------------------------------------------------------------- - 41,422 1967 1 share for every 5 share held 2 82,844 ------------------------------------------------------------------------- - 21,849 1968 1 share for every 3 shares held 3 65,547 ------------------------------------------------------------------------- 1004 10 10,040 ------------------------------------------------------------------------- 7613 + 1,22,387 = 1,30,00 shares 4,67,842 ------------------------------------------------------------------------- 1,30,000 shares sold at the rate of Rs. 56.75 realising Rs. 73,77,500 as against the cost price of Rs. 4,67,842. Subsequently, the Income-tax Officer felt that full details as to how the value of the bonus shares was computed by the assessees was not furnished at the time of original assessment. He required the petitioners to furnish necessary details. When the assessees did not furnish the details as required the Income-tax Officer issued the impugned notice under section 148 read with section 147(a) to file return of income in response thereto. However, during the pendency of this writ petition, the re-assessment was completed, as a result of which the income under the head capital gains was computed at Rs. 69,93,879/- as against Rs. 69,09,658/- computed originally. However, during the pendency of this writ petition, the re-assessment was completed, as a result of which the income under the head capital gains was computed at Rs. 69,93,879/- as against Rs. 69,09,658/- computed originally. The first question that requires consideration is whether the reasons recorded by the Income-tax Officer for re-opening the assessment under section 147(a) have a direct nexus or live link with the formation of the belief that the income of the assessee chargeable to tax had escaped assessment. For this purpose, it is desirable to refer to the reasons recorded by the Income-tax Officer. They are :- "It is seen from the records that assessee has show long term capital gains of Rs. 69,09,658/- on the sale of shares of Great Eastern Shipping Co. Ltd. The shares sold include bonus shares also. The details of basis on which the cost of the bonus shares have been calculated has not been furnished by the assessee. Accordingly the assessee was asked to furnish the details vide letter of even No. dated 22.2.1984 fixing the case for 29.2.1984 (11 a.m.). No details have been furnished in this respect till date. Therefore, I have reason to believe that by reason of omission or failure on part of the assessee to disclose truly and fully all the material facts necessary for A.Y. 1975-76 income chargeable to tax has escaped assessment for the A.Y. 1975-76." It is evident that the Income-tax Officer merely observed that the assessee had not filed complete particulars as regards computation of the valuation of the bonus shares. From that fact he assumed that the assessee's income chargeable to tax must have escaped assessment. For the present, it may be assumed that the petitioners had not given the basis as to how they had valued their bonus shares at Rs. 2/- per share in some years and at Rs. 3/- per share in other years and this amounted to non-disclosure of full particulars. However, this Court is not in agreement with Shri Jetley that non-disclosure of certain facts must necessarily lead to the formation of belief that income chargeable to tax had escaped assessment. As best, such a non-disclosure could lead to suspicion that the income assessed might to might not have been the correct income. To illustrate the point, let us assume case of an assessee who does not file his return of income. As best, such a non-disclosure could lead to suspicion that the income assessed might to might not have been the correct income. To illustrate the point, let us assume case of an assessee who does not file his return of income. Mere fact that returns of income were not filed cannot by any stretch of imagination lead to the belief that income assessable to had escaped assessment. For formation of that belief you require something more than the mere fact of non-filing of return or non-disclosure of what is considered by the Income Tax Officer to be full particulars. Indirect support for the view is available in the decisions of the Supreme Court in the case of ITO v. Lakhmani Mewal Das, 103. ITR 437 and in the case of ITO v. Madnani Engineering Works Ltd. 118 ITR 1. In the above view of the matter, the notice issued is without jurisdiction and is hereby quashed. As a consequence thereof, the assessment made in pursuance thereof will also have to be quashed. In the result, rule is made absolute in terms of prayer clause (a) and the amended prayer (c)(1). No order as to costs.
