Rajapalayam Mills Ltd. v. Commissioner of Income Tax, Madras

BHAGWATI J., These two appeals by special leave raise a short but interesting question of Law relating to the interpretation of section !SC of the Indian Income Tax Act. 1922 and section 84 of the In-come Tax Act, 1961. These two sections are in material respects in identical terms and the interpretation we place on section I SC is bound to apply equally to section 84. We will, therefore. first deal with Civil Appeal 1989 of 1972 which involves the interpretation of section lSC and then tum to Civil Appeal 2418 of 1977 which deals with section 84.

The assessee in Civil Appeal 1989 of 1972 is a public limited company carrying on business in manufacture and sale of yarn. Dur-ing the financial year ending 31st March. 1959. being the accounting year relevant to the assessment year 1959·60, the assessee set up a new industrial undertaking which admittedly satisfied the requirement of section 15C(2) of the Indian Income Ta" Act, 1922. The profit. depreciation and development rebate in respect of this new un[t for tbe assessment years 1959-60 and 1960-61 were as follows:

,lfl Year Profit Depreciation and Development Rebate

1959-60 Rs. 33, 118/- Rs. 1,4', 361/- Rs. 5,07, 336/-(Development rebate) i_

1960-61 Rs. 3, 64, 672/- Rs. 3,19, 591/- Rs. 1,17, 205/-(Development rebate) Rs. 3, 97, 790/- Rs. 10, 88,493/- fn the assessment year 1959-60 the total profit of the assessee in res-pect of its old and new units came to Rs. 2,4.2,432/-, including Rs. 33, 118/- in respect of the new unit and the total depreciation amounted to Rs. 2,66,651 including Rs. J,44,361 in respect of the new unit and after setting off the amount of depreciation against the total profit, a sum of Rs.24,183/-remained as unabsorbed depreciation which was carried forward to the next year. The entire development rebate which included Rs. 5,07,336/- in respect of the new unit, also re-mained unabsorbed owing to the smallness of the profit and that too bad to be carried forward. The total profit of the assessee in respect of its old and new units for the assessment year 1960-61 was Rs. 14,13.6(}4/- inclusive of Rs 3,64,672/- in respect of the new unit and this was large enough to absorb the carried forward depre-ciation and development rebate as also the current year's depreciation and development rebate in respect of both the units. In fact, after setting off of such depreciation and development rebate, a sum of Rs. 3,25,176/- remained as the taxable income of the assessee and it was assessed to tax in its bands. The result was that no part of J the depreci~tion or development rebate for the assessment years 1959-

60 and 1960-61 remained unabsorbed 'to be carried forward to the next assessment year 1961-62.

· The position in the assessment year 1961-62 was that the assessee earned a net business i'I!come of Rs. 12,69,403/- which included a sum of Rs. 1,36,822/- repres·enting the income from the new unit. The assessce in its assessment to tax for this assessment year claimed exemption of. the income from the new unit to the extent of 6 % of the average capital employed in it under section 15C. This secti'on insofar as material read as follows :

( 1 ) Save as otherwise hereinafter provided, the tax shall

not be payable by an assessee on so much of the profits or gains derived from any industrial underta-ki•ng (or hotel) .to which this section applies as do not exceed six per cent per annum on the capital

an industrial undertaking, apply) to the assessment :E for the financial year next fo!Jowing the previous year

The Income-Tax Officer took the view.that the benefit of section 15C, sub-6'ection ( 1) could be claimed by the assessee only if thece was any profit derived from the new unit and since this profit wos, by reeson of sub-section ( 3) of section l 5C, required to be computed in accordance with the provisions of section 10, it was necessary to worki out the trading result of the new unit without reference to any other activity carried on by the assessee and if that was done, the result would clearly show there was a loss in the working of the new unit in the assessment year 1961-62. The computation made by the Income Tax Officer was as under. The total depr~ciation and development rebate in respect of the new unit for the assessment years 1959-60 and 1960-61 was Rs. 10,88,493/-, while the profit for these two a55essment years came to only Rs. 3,97,790/- so that, taking into account only the trading result ot the new unit as if that was the only source ot income of the a.Ssessee during the assessment years 1959-60 and 1960-61, a sum of Rs. 6,90,703/- representing the excess of depreciation and <levelopment rebate over profit re-mained unabsorbed to be carried forward to the next assessment ymc 1961-62. If this carried forward depreciation and development re-bate amounting to Rs. 6,90,703/- were allowed against the profit of Rs. 1,36,822/- derived from the new unit in the assessment year 1961-62, there would be a resultant loss and hence the benefit of the exemption under section 15C, sub-section ( 1) was held not available to the assessee and! the claim of the assessee for exemption was re-jected.

The assessee carried the matter iu appeal and before the Appel-late Assistant Commissioner, the assessetl succeeded in making good its claim for exemption under section !SC, sub-secti<on (1). The Appellate Assistant Commissioner pointed out in a brief but prec~e order: "The loss of Rs. 6,90,703/- being depreciation iu excess of the income made by the new mill was set off against the income of the old mill in both the years and the net result for the assessment year 1960-61 was a positive figure which was assessed to tax. There is no question of once again carrying forward the deprei:iation of the new mill to the assessment year 1961-62 and allowing it against the income of tho new mill. It is only when there is a loss of the earlier year due to depreciation attributable to the new indus-trial undertaking which could not be set off against the profits of the earlier years, it has to be carried forward and set off against the income of the current year in working out the income liable to tax under section 10". The Appellate Assistant Commissioner accord-ingly allowed the claim for exemption and directed the Incdme Tax Officer to modify the assessment in conformity with his decision.

The Revenue being aggrieved by th~ decision of the Appellate Assistant Commissioner preferred an appeal before the Income Tax Appellate Tribunal. The appeal was successful and the Tribunal set aside the order of the Appellate Assistant Commissioner and restored that of the Income Tax Officer. The Tribunal took the view ·that the trading result of the new unit must be considered as if it stood by itself, ignoring every other income producing activity of the assessee and if that was done, it was clear that there was an unabsorbed dep-reciation and development rebate of Rs. 6,90, 703/- in respect of the new unit which was required to be carried forward and treated as part of the allowance for the assessment year 1961-62 and that would wholly wipe out the profit of Rs. 1,36,822/- leaving a resultant lOiS in the new unit for the assessment year 1961-62. The Tribunal in thi's view held that the benefit of the ~emption under section l SC, sub-section (1) was not available and the Income Tax Officer was justified in refusing to grant such exemption.

114 6 SUPREME COURT REPORTS [1979] I s.c.R.

This led to the filing of an application for reference by the assessee and· on the application, the Tribunal stated 3J case and referred the folldwing question of law for the opinion of the High Court :

"Whether on the facts and in the circumstances of the case the assessee company was entitled to the relief under section 15C(2)".

The IDgh Court agreed with the view taken by the Tribunal and proceeding on the assumption that for the purpose of determining the appfa:ability of section 15C, sub-section (I), the new unit was re-quired to be treated in isolation, as if no other income producing activity was carried on by the assessee, the High Court '>bserved that there was unabsorbed depreciation and development rebate of Rs. 6,90,703/- in respect of the new unit which was required to be carried forward and set off against the profit of Rs. 1,36,822/- de-rived from the new unit in the assessment year 1961-62 and since that left the new unit in a resultant position of loss, the assessee was not entitled to claim the benefit of the exemption under section 15C, sub-section (1). The High Court accordingly answered the question referred by the Tribunal i'n favour of the Revenue and against the assessee. The assessee thereupon preferred the present Civil Appeal No. 1989 of 1972 after obtaining certificate of fitness from the High Court.

111e same question also arose in the assessment of the assessee to tax for the assessment year 1962-63, but in this assessment year the law in force was the Income Tax Act, 1961 which had come into force with effect from 1st April, 1962. The corresponding provision in section 84 of the new Act was however, in material respects in the same terms as section 15C of the old Act. The claim for exemption made by the assessee under section 84 for the assessment year 1962-63 met with the same fluctuating vicissitudes of fortune as the claim for the earlier assessment year and ultimately, the Tribunal having decided against the assessee, a reference of the question whether on the facts and the circumstances of the case the assessee was entitled to r exemption under section 84 was made to the High Court. The High Court in view of its decision for the earlier assessment year, decided against the assessee and hence, the present Civil Appeal No. 2418 of 1977 was brought by the assessee after obtaining certificate of fitness from the High Court. Since both sections ! 5C and 84 are, for all material purposes, in identical terms, we will discuss the interpreta-tion and applicability of section !SC in Civil Appeal No. 1989 of 1972 and the view we take in that appeal will equally govern the de-cision of Civil Appeal No. 2418 of 1977.

The law of income tax in a modern society is intended to achieve various social and economic objectives. It is often used as an instru-ment for accelerating economic grnwth and development. Section 1 SC is a provision intrnduced in the Indian Income Tax Act, 1922 with a view to carrying out this objective and it is calculated to encourage setting up of new industri~l undertakings in the country. Sub-sec-tion (I) of this section exempts from tax so much of the profits or gains derived from a new industrial undertaking as do not exceed 6% per annum of the capital employed in the undertaking. There are rules made under the Act for computing the capital employed in a new industrial undertaking but we are not concerned with these rules in the present appeals. What is material is only the provision for exemption and according to this provision, the profits and gains of a new industrial undertaking are exempt from tax to the extent of 6% per annum of the capital employed, and obviously, therefore, there must be prnfits or gains derived from the new industrial undertaking in the assessment year in question before any claim for exemption can be sustained under section 15 C, sub-section (1 ) . If there are no profit or gains derived from the new industrial undertaking in any particular assessment year, there can be no question of any ex-emption, because it is only where there are such profits or gains that to the extent of 6% per annum of the capital employed, they become eligible for exemption. The first question which must, therefore, arise for consideration in every case where a claim for exemption is made under section !SC, sub-section(!) is whether there are any profits or gains derived from the new industrial undertaking in the assessment year in question, and if so, what is the quantum of such profits or gains. Now, sub-section (3) of section 15C says that the profits or gains of a new industrial undertaking shall be com-puted in accordance with the provisions of section 10 and since under the income tax law, every assessment year is a self-contained period, prnfits and gains of the new undertaking must be computed for the par-ticular assessment year in respect of which the claim for exemption is made, by applying the provisions of section 10. Sub-section (2) of that section provides for various allowances to be made in computing profits and gains of a business and amongst such allowances are one in respect of depreciation and the other in respect of development rebate. Gause (vi) of sub-section '(2) deals with allowance for depreciation and it says that in computing the profits or gains of a business allowance shall be made, in respect of depreciation of building, machinery, plant or furni-ture belonging to the assessee and used for the purpose of the business, a sum equivalent to "such percentage on the written down value thereof as may in any case or class of cases be prescribed". Depreciation cal-culated in accordance with the provisions of clause (vi) is thus allowable in computing the profits and gains of a business chargeable to tax and if the profits and gains of the business are insufficient to absorb such depreciation allowance, the .amount of the allowance to the extent it is unabsorbed, must, like any other business loss be set off against the profits of any other business. It is settled law that though the profits of each distinct business carried on by an assessee have to be computed separately in accordance with the provisions of section 10, the tax is chargeable under that section not separately on the profits of each busi-ness, but on the aggregate of the profits of all the businesses carried on by the assessee. Vide Anglo-French Textile Co. Ltd. v. Commissioner of Income-tax('), Commissioner !of Income tax v. Inda-Mercantile Bank Ltd.(") and Commissioner of Income-tax v. Muthuraman Chettiar('). It follows, therefore, that where the assessce carries on several business-es, he is entitled under section 10 to set off loss in one business against profits in another. If there is any loss in a business carried on by the assessee by reason of the profits of such business not being suffi-cient to absorb the dep!'.eciation allowance, such loss can be set off against the profits of another business carried on by the assessee. If, however, there are no profits chargeable under the· head 'Business or profession' or if the profits chargeable under that head are insufficient to cover the depreciation allowance, the amount of the allowance to th extent to which it is not absorbed can be set off against profits chargeable under any other head for that assessment year. This is the plain and undoubted effect of section 24, sub-section ( 1) as explained in Com-missioner of Income-tax v. Inda-Mercantile Bank Ltd. (supra). But what would happen if still some part of the depreciation allowance remains unabsorbed. The answer is p!'.OVided by proviso (b) to clause (vi) of section 10 which reads as follows :

r "Provided that- (a) x x x (b) Where, (in the assessment of the assessee or if the r

assessee is a registered firm, in the assessment of its partners,) full effect cannot be given to any such allowance in any year (not being a year which ended prior to the 1st day of April, 1939), owing to there being no profits or gains chargeable for that year or ------ owing to the profits or gains chargeable being less than

(!} 23 I.T.R. 82 at 86 (2) 36 I.T.R. I at 6 (3) 44 I.T.R. 710 at 713.

the allowance, (then, subject to the provisions of clause (b) of the proviso to sub-section (2) of sec-tion 24), the allowance or part of the allowance to which effect has not been given as the case may be, shall be added to the amount of the allowance for depreciation for the following year and deemed to be part of that allowance, or if there is no such allo-wance for that year, be deemed to be the allowance for that year, and so on for succeeding years :

lt is clear on a plain reading of the language of proviso (b} to clause (vi) that it comes into operation only where full effect cannot be given to the depreciation allowance for the assessment year in question owing to there being no profits or gains chargeable for that year or profits or gains chargeable being less than the depreciation allowance. Now, it is well settled, as a result of the decision of this Court in Commissioner of Income-tax v. Jaipuria China Clay Mines( 1) that the words 'no profits or gains chargeable for that year' are not confined to profits and gains derived from the business whose income is being computed under section 10, but they refer to the totality of the profits or gains computed under the various heads and chargeable to tax. It is, therefore, clear that effect must be given to depreciation allowance first against the profits or gains of the particular business whose income is being computed under section 10 and if the profits of that business are not sufficient to absorb the depreciation allowance, the allowance to the extent to which it is not absorbed would be set off against the profits of any other business and if a part of the depreciation allowance still remains unabsorbed, it would be liable to be set off against the profits or gains chargeable under any orher head and' it is only if some part of the depreciation allowance still remains unabsorbed that it can be carried forward to the next assess-ment year. Obviously, therefore, there would be no scope for the appli-cability ot proviso (b) to clause (vi) if the total income of the assessee chargeable to tax is sufficient to absorb the depreciation allowance, for then there would not be any unabsorbed depreciation allowance to be carried forward to the following assessment year. But where any part of th~ depreciation allowance remains unabsorbed after being set off against the total income chargeable to tax, it can be carried forward under proviso (b) to clause (vi) to the following year and set off against that years' income and so on for succeeding years. The method adopted by the statute for achieving this result is that the carried forward depre-ciation allowance is deemed to be part of and stands on exactly the same footing as, the current depreciation for the assessment year and is thus allowable as a deduction under clause (vi). It would, therefore, be seen that when the profits or gains of a business for a pa1ticular assess-ment year are to be computed under section 10, the current depreciation allowance for the assessment year in question is deductible under clause (vi) but the depreciation allowance of the preceding years would be liable to be taken into account only if, and to the extent to which, it i• not absorbed by the total income of the assessee computed under diffe-rent heads and chargeable to tax for those '"se>Smcnt years.

The position in regard to development rebate is the same. The relevant provision in that behalf is to be found in clause (vi-b) of sub-section (2) of section 10. That clause, insofar as material, provides as follows:

"10(2). Such profits and gains shall be computed after making the following allowances, namely, ( vi-b) in respect of new machinery or plant installed after the 31st day of March, 1954, which is wholly used for the purposes of the business carried on by the assessec, a sum by way of development rebate in respect of the year-nf the install,ition of the machinery or plant, equivalent to,-

(i) (ii) in the case of machinery or plant installed before the

1st day of April. 1961, twenty-five per cent and in the case of machinery or plant installed ofter 31st day of March, 1961, twenty per cent of the actual cost of the machinery or plant to the assessee;

Explanation I. In the case of --machinery or plant

installed after the 31st day of December, 1957, where y the total income of the assessee for the year of--in-stallation (the total income for this purpose being com-puted without making any allowance under this clause) is nil or is less than the full amount of the development rebate calculated at the rate applicable thereto under this clause,- (i) the sum to be allowed by way of development rebate

for that year under thi•s clause shall be only such amount as is sufficient to reduce the said total in-come to nil; and (ii) the amount of the development rebate, to the extent

to which it has not been allowed as aforesaid, shall be - • •x teo/' RAJAPALAYAM. MILLS v. C.I.T. (Bhagwati, J.) 1151 carried forward to the following year, and the deve-lopment rebate to be allowed for the following year shall be such amount as is sufficient to reduce the total income of the assessee for that year, computed in the manner aforesai'd, to nil, and the balance of the qevelopment rebate, if any, still outstanding shall be carried forward to the following year and so on, so however that no portion of the development rebate shall be carried forward for more than eight years; The amount of development rebate in respect of new machinery used for the purpose of the business is allowable in the year of in-stallation of the machinery under sub-clause (ii) of clause (vi-bJ, but· Explanation ( 1) provides that if the total income of the assessee for the year of installation is nil or is less than the full amount of the development rebate, the amount of the development rebate, to the extent to which it is not absorbed, may be carried forward to the following year and set off against the total income of the assessee for that year and if even thereafter, a part of the development rebate re-mains unabsorbed, the balance outstanding may be carried forward to the following year and so on for an aggregate period not exceeding eight years. Though the amount of the development rebate is, under the main provision in sub-clause (ii) of clause ( vi-b), allow-able in the first instance against the P\Ofits or gains of the particular husiness wl)ose profits or gains are being computed, clause (i) of Explwation ( 1) makes it clear that· if any part of the development rebate remains unabsorbed, it is to be set off against the other income J of the assessee ·under any of the chargeable heads and it is only if

some part of the development rebate still remains outstanding that it can be carried forward to the following assessment year and set off against the total income of the assessee for that year. The amount of the development rebate is to be set off against the total income of the assessee and not merely against the profits or gains of the parti-cular business in respect of which the development rebate is granted and so also the development rebate which remains unabsorbed and is carried forward to the next assessment year is, by reason of clause (ii) of Explanation 1 to be set off not merely against the profits or gains of the particular business but against the total income of the assessee for that year. It would, therefore, be seen that it is only where the amount of development rebate has not been fully set off against the total income of the assessee in the past assessment years ff and a part of it still remains unabsorbed and is carried forward to me assessment year in question that it can be allowed against the profits or gains of the business for the particular assessment year and if there is still some balance outstanding, then against the other income of the assessee for that assessment year. But i'f the amount of the develop-ment rebate is wholly set off against the total income of the assessee in the past assessment years and there is no unabsorbed development rebate to be carried forward to the assessment year in question, there )c. would be nothing in respect of the past development rebate to be set off against the profits or gains of the business under clause (ii) of Explanation 1. It is, therefore, necessary, when the profit, or gains of business are being computed under section 10 to ask the question whether the machinery in respect of which the development rebate is admissible has been installed in the asse~mcnt year in question, and if it is found that it has been installed earlier, whether any part of the development rebate has remained unabsorbed against the total incomr of the assessee in the past assessment years and is carried forward to the present assessment year. In a case where the machinery is in-stalled in an earlier assessment year, it is only if the whole of the development rebate has not been fully set off against the total income of the assessee in the past assessment years and a part of it has re-mained unabsorbed and is carried forward that it can be set off &gainst the profits or gains of the business for the garticular assessment year. But if the whole of the development rebate has been absorbed and no part of it is carried forward, there can be no question of allowing it against the profits or gains of the business for the assessment year in question.

Now, sub-section (3) of section !SC provides that the profits or gains of a new industrial undertaking shall be computed under section 10 and, therefore, according to clause (vi) read with provi'So (b), no part of the depreciation allowance and according to clause ( vi-b) Explanation 1, no part of the development rebate in respect of the r new industrial undertaking for the past assessment years can be allow-ed as a deduction in computing the profits and gains, unless it has remained unabsorbed by reason of inadequacy of the total income chargeable to tax in the past assessment years--and, as pointed our above, by total income we mean not only profits or gains derived from the new industrial undertaking but the totality of profits or gains com-puted under various heads-and is carried forward to the assessment year in question. There is nothing i•n sub-section (3) of section 15C or in any other provision of the Act which requires that in computing the profits or gains of a new industrial undertaking under section 10, depreciation allowance or development rebate in respect of the new industrial undertaking for the past assessment years should be taken into account, even if it has been set off fully again~t the profits or gains of any other business carried on by the assessee or against income under any other head and there is no unabsorbed depreciation allow-I ance or development rebate to be carried forward. It Is indeed diffi-

cult to see how effect can be given to depreciation allowance and development rebate twice over, once in the past ~sessment years and again in the assessment year in question. To give effect to deprecia-tion allowance or development rebate for the past assessment years, even though it has been set off and absorbed completely against the total income of the assessee for those assessment years would be to allow a deduction not warranted by any provision of the Act and in-deed it would be going contrary to tl:te express provision of proviso (b) to clause (vi) and Explanation 1 to clause (vi-b). Sub-section (3) of section lSC clearly does not have any such effect. What it does is no more than provide as to how "the profits or gains derived from new industrial undertaking" referred to in sub-section ( 1) of section 15C shall be computed. If sub-section (3) of section 15C had not been enacted, it might have been a matter of some contro-versy as to what is meant by the expression "the profits or gains de-rived from new industrial undertaking". Does it mean commercial profits or gains or profits or gains chargeable to tax or does it have any other connotation? It was to sef this controversy at rest that sob-section (3) of section 15C enacted that the profits or gains of the new industrial undertaking shall be computed in accordance with the provisions of section 10. It may be noted that sub-sec.tion (3) of section 15C does not enact any legal fiction providing that the profits or gains of the new industrial undertaking shall be computed as if the new industrial undertaking were the only business of the assessee from the da~ of its establishment or the past years depreciation or development rebate had not been set off against other income of the assessee. The new industrial undertaking is not retrospectively quarantined or isolated from the other income producing activities of tke assessee for determining its profits or gains for the purpose of applicability of sub-section (1) of section 15C. What sub-section (3) of section !SC does is merely to lay down the same rule of com-pul!ation for the profits or gains of a new industrial undertaking as in respect of any other business and, therefore, neither depreciation allowance nor development rebate ln respect of the new industrial undertaking for the past assessment years can be allowed as a deduc-_J tion in computing the profitS or gains for tl:te assessment year in

question, except where and to the extent to which, it has not been set off against the total income of die assessee for those assessment years and bas remained unabsorbed. This is the plain and undoubted ·effect of the language used in sub-sectioo (3) of section 15C. Indeed

the language is so clear and unambiguous that it is impossible to place any other construction upon it. But apart from the language of the section, it may be noted that if the construction contended for on behalf of the Revenue and upheld by the High Court as well as by the Tribunal were accepted, it would lead to the highly anomalous results that, though, for the purpose of computing the total income chargeable to tax, the depreciation allowance and development rebate which have been set off against the other income of the asses-see for the past assessment years would not be liable to be taken into account, they would have to be deducted in computing the profits or gains 'of the business for the purpose· of applicability of sub-secti'On (1) of section 15C. Thus, there would be two different modes of determining the profits or gains of the business, one for computing the total income chargeable to tax and the other for applying the provi-sions of sub-section (!) of section 15C. \Ve cannot imagine that such a consequence would ever h"'·e been intended by the Legisfa-ture.

We find in the present case from the undisputed figures on record that the whole of the depreciation allowance of Rs. 1,44,361/- in respect of the new industrial undertaking for the assessment year 1959-60 could not be absorbed owing to the total profit of the asses-see being insufficient and a sum of Rs. 24,1831-remained as unab-sorbed depreciation which was carried forward to the assessment year 1960-61. The entire development rebate of Rs. 5,07,336/- also remained unabsorbed and had to be carried forward to the as-sessment year 1960-61. But during the assessment year 1960-61 the total profit of the asscsscc came to Rs. 14,13,604/-and this was sufficient to absorb not only the carried forward depreciation of Rs. 24,183/- and the current year's depreciation, but also the carried forward development rebate of Rs. 5,07,3361-and the development T. rebate of Rs. 1,17.205/- in respect of machinery installed in that assessment year. The result was that no part of the depreciat,'On allowance or development rebate remained unabsorbed to be .carried forward to the assessment year J 961-62. If that be so, it is difficult r to see how any part of the depreciation allowance or development re-bate could possibly be allowed as a deduction in computing the pro-fits or gains of the new industrial undertaking for the assessment year 1961-62. It is only if a part of the depreciation allowance or deve-lopment rebate had remained unabsorbed against the total income of the assessee in the past assessment years that it could be carried for-ward and set off against the profits or gains of the new industrial un-dertaking for the assessment year 1961-62. But when admittedly entire depreciation allowance and development rebate for the past assessment years were fully set off against the total income of the assessee for those assessment years and no part of the depreci'ation allowance or development rebate remained unabsorbed, nothing could be deducted in respect thereof and hence, for the purpose of sub-section (1) of section 15C the profits or gains of the new industrial under-taking for the assessment year 1961-62 came to Rs. 1,36,822/- aud the assessee was in the circumstances, entitled to the benefit of the exemption under section 15C, sub-section ( 1). We are, therefore, of the v;•cw that the High Court as well as the Tribunal were in error in refusing the benefit of the exemption under section 15C, sub,section ( 1) to the assessce for the assessment year 1961-62. The same view must also prevail in regard to the assessment year 1962-63 for, as we have pointed out above, section 84 of the new Act is, in material respects. identical as section 15C of the old Act. The reasoning which has weighed with ns must apply equally in regard to the assess-ment year 1962-63 and we must likewise hold that the assessee was entitled to the benefit of the exemption under section 15C, sub-section (1) in respect of the assessment year 1962-63 also.
