Summarize the following court judgment. Civil Appeal No. 47 (N T) of 1975. From the Judgment and Order dated 3.10.1974 of t he Gujarat High Court in I.T. Reference No. 30 of 1973. Bishambar Lal for the Appellant. V.S. Desai	 B. Rao and Ms. A. Subhashini for the Responden t. M.B. Lal for the Intervener. (N.P.) 88 The Judgment of the Court was delivered by PATHAK	 C.J. This appeal by certificate granted by t he High Court of Gujarat is directed against the judgment of the High Court on the following questions referred to it by the Appellate Tribunal: "1. Whether	 on the facts and in the circumstances of the case	 the Tribunal was fight in holding that the asse s see cannot be denied the benefit of carry forward of deve l opment rebate? 2. Whether	 on the facts and in the circumstances of the case	 the Tribunal was justified in directing that t he Income tax Officer should determine the development reba te and such development rebate should be allowed to be carri ed forward and set off when profits are available and if	 in that year	 the assessee fulfils the necessary requiremen ts for such allowance like creation of adequate reserve?" The assessee is a limited Company. It has a textile mi ll at Cambay in the State of Gujarat. For the assessment ye ar 1962 63	 the previous year being the calendar year 1961	 t he assessee claimed that a sum of Rs. 1	26	233 should be a l lowed as development rebate under section 33 of the Income t ax Act	 1961. The Income tax Officer rejected the claim on t he ground that the assessee had not created a reserve as co n templated by sub section (3) of section 34 of the Income tax Ac t	 1961. The Appellate Assistant Commissioner of Income T ax dismissed the appeal filed by the assessee. In second appe al the claim by the assessee found favour with the Income T ax Appellate Tribunal. At the instance of the Revenue t he questions set forth earlier were referred to the High Cou rt for its opinion. The High Court has answered the questio ns in favour of the Revenue and against the assessee. It h as held that the assessee had failed to comply with the cond i tions of sub section (3) of section 34 of the Act. In this appeal by the assessee it is urged that the vi ew taken by the High Court is erroneous and that it is n ot necessary that a reserve should be created in the previo us year during which the machinery or plant was installed. Sub section (1) of section 33 provides that development rebate m ay be claimed as a deduction in respect of a new machinery or plant installed 89 after 31 March	 1954 which is owned by the assessee and is wholly used for the purposes of the business carried on by him	 and that the allowance of the deduction is subject to the provisions of section 34. (a) of sub section (3) of section 34 provides that the deduction referred to in section 33 shall n ot be allowed unless an amount equal to 75 per cent of t he development rebate to be actually allowed is debited to t he profit and loss account of the relevant previous year a nd credited to a reserve account to be utilised by the assess ee during a period of eight years next following for the pu r poses of the business of the undertaking	 other than f or distribution by way of dividends or profits or for remi t tance outside India as profits or for the creation of a ny asset outside India. The Finance Act	 1966 added an Explan a tion to this clause. The Explanation declared that t he deduction referred to in section 33 could not be denied by reas on only that the amount debited to the profit and loss accou nt of the relevant previous year and credited to the aforesa id reserve account exceeded the amount of the profit of su ch previous year (as arrived at without making the depos it aforesaid) in accordance with the profit and loss accoun t. The Explanation was inserted with retrospective effect fr om the commencement of the Act. Before the Explanation w as enacted a difference of opinion had existed between the Hi gh Courts on the question whether the statute required t he creation of a reserve in the previous year in which the n ew machinery or plant was installed	 when the amount of t he profit of that previous year was either nil or insufficie nt for the purposes of enabling the creation of such reserv e. It is not necessary to refer to these cases	 for it see ms clear to us that the Explanation	 which applied to t he assessment year under consideration before us	 removes t he doubt altogether. What is contemplated is the creation of a Reserve Fund in the relevant previous year irrespective of the result of the profit and loss account disclosed by t he books of the assessee. Mere book entries will suffice f or creating such a Reserve Fund. The debit entries and t he entries relating to the Reserve Fund have to be made befo re the profit and loss account is finally drawn up. That is a condition for securing the benefit of development rebate a nd if that condition is not satisfied we fail to see how t he deduction on account of development rebate can be claimed at all. Learned counsel for the assessee relies on West Laikdi hi Coal Co. Ltd.	 Calcutta vs Commissioner of Income tax	 We st Bengal 11	 and Commissioner of Income ta x	 Delhi Central vs Modi Spinning & Weaving Mills Co. Ltd . 	 Those were cases decided under the prov i sions of the Indian Income tax Act	 1922 and there was no Explanation such as we have before us. Re 90 ference was made to the decision of this Court in Indi an Overseas Bank Ltd. vs Commissioner of Income tax Madra s	 In that case	 however	 the question w as whether the creation of a reserve in compliance with section 17 of the Banking Companies Act constituted sufficient compl i ance with the requirements of proviso (b) to section 10(2) (vi b) of the Indian Income tax Act	 1922. Reference has also be en made to Additional Commissioner of Income tax vs Vishnu I n dustrial Enterprise	 We do not find it possible to agree with the view taken by the Allahabad Hi gh Court in that case that the development reserve need not be created in the relevant previous year during which the n ew machinery or plant is installed	 and that a profit must ha ve been earned during the previous year to permit the creati on of a reserve fund. We think that the Explanation is clea r	 and that there can be no doubt that it envisages the cre a tion of a Reserve Fund notwithstanding that there is no profit or insufficient profit from which such reserve may be provided. To contemplate otherwise would be to negate t he entire scheme incorporated in section 33 read with section 34 of t he Act. For the same reason we are unable to affirm the vi ew taken by the Allahabad High Court in Commissioner of Income tax vs U.P. Hotel and Restaurants Ltd.	 [1984] 1 Our attention has been drawn by the learned couns el for the assessee to Dodballapur Spinning Mills Ltd. vs Commissioner of Income tax	 Karnataka 2 and Anr.	 [1980] 1 where reference has been made to a circular issued by the Central Board of Direct Taxes dated 14th October	 19 65 and to a subsequent circular dated 30 January	 1976. We ha ve carefully considered the matter and we do not think that t he circulars affect the true position in law. On behalf of the assessee reliance was placed on Indi an Oil Corporation Ltd. vs section Rajagopalan	 Income tax Office r	 Companies Circle II (1) Bombay and others	 41 where the Bombay High Court has held that there was no obligation on the assessee to create a reserve in the ye ar of installation if there was no taxable income in the rel e vant year. Some of the submissions addressed in that ca se may be set forth in detail. A powerful argument was a d dressed by learned counsel for the assessee and it w as pointed out that the expression "shall be allowed" in clau se (a) of sub section (1) of section 33 indicated that the developme nt rebate is to be assessed and thereupon it becomes allowabl e	 and that sub section (2) of section 33 which provides for the allo w ance of development rebate mentions that the sum "to be allowed" by way of development rebate for the assessme nt year shall be only such amount as shall be sufficient to reduce the total assessable income to nil and the amount of development rebate to the extent to which 91 it has not been allowed shall be carried forward to t he following assessment years for eight subsequent year section Reference was also made to the distinction between t he expressions "to be allowed" and "actually allowed" used in the relevant provisions. It was also argued that the util i sation by the assessee of the development rebate reserve f or the purposes of the business of the undertaking contemplat ed the existence of an actual fund which could be utilised f or the purposes of the business	 and that an illusory deb it entry in the profit and loss account and an illusory cred it entry in the development rebate reserve account were n ot contemplated. The High Court accepted the submission a nd concluded that it was not mandatory that the necessary deb it and credit entries must be made in the assessment ye ar following the year of installation in which the developme nt rebate is determined under section 33. Having considered t he matter at some length in the present case	 it seems to us clear that in order to claim the deduction on account of development rebate under sub section (1) of section 33 it is obligat o ry that the debit entries in the profit and loss account a nd the credit entry in a reserve account should be made in t he relevant previous year in which the machinery or plant is installed or first put to use. The development rebate co n templated by sub section (1) of section 33 cannot be allowed as a deduction unless a reserve account has been created in t he previous year in which the installation or first use occur section Any doubt in so reading the provisions because of a want or insufficiency of profit in such previous year has be en removed by the Explanation to clause (a) of sub section (3) of section 34. The significance of the words "actually allowed" in clause (a) of sub section (3) of section 34 has been considered by t he High Court in the judgment under appeal	 and we are in entire agreement with the view taken by the High Court in that ' regard. A number of other cases have also been placed before us by learned counsel for the assessee	 but as they deal wi th the point on the basis of considerations substantially t he same as have been referred to in the cases mentioned earl i er	 we think it unnecessary to deal with them specifically . Upon the aforesaid considerations we hold that the Hi gh Court is right in answering the questions in favour of t he Revenue and against the assessee. In the result	 the appeal is dismissed but there is no ord er as to costs. H.L.C. Appeal di s missed.

Sub section (1) of section 33 of the Income Tax Act	 1961 provid es that subject to the provisions of section 34 thereof developme nt rebate may be claimed as a deduction in respect of a n ew machinery or plant. Clause (a) of sub section (3) of section 34 stip u lates that the said deduction shall not be allowed unless an amount equal to 75 per cent of the development rebate is debited to the profit and loss account of the releva nt previous year and credited to a reserve account; and t he Explanation thereto provides that the deduction shall not be denied by reason only that the amount so credited to t he reserve account exceeded the amount of the profit of su ch previous year. The appellant assessee which had a textile mill claim ed a sum as development rebate for the assessment year 1962 6 3. The Income Tax Officer rejected the claim on the ground th at the assessee had not created a reserve as contemplated by sub section (3) of section 34 and his order	 on appeal	 was upheld by the Assistant Commissioner. In second appeal	 the claim by the assessee found favour with the Appellate Tribunal; b ut on a reference made by it at the instance of the Revenu e	 the High Court held that the assessee had failed to comp ly with the conditions of sub section (3) of section 34. The appella nt contended that the view taken by the High Court was erron e ous and that it was not necessary that a reserve should ha ve been created in the previous year. Dismissing the appeal	 HELD: In order to claim the deduction on account of development rebate under sub section (1) of section 33 it is obligat o ry that the debit entries in the profit and loss account a nd the credit entry in a reserve account should be made in t he relevant previous year in which the 87 machinery or plant is installed or first put to use. T he development rebate contemplated by sub section (1) of section 33 cannot be allowed as a deduction unless a reserve accou nt has been created in the previous year in which the install a tion or first use occurs. Any doubt in so reading the prov i sions because of a want or insufficiency of profit in su ch previous year has been removed by the Explanation to clau se (a) of sub section (3) of section 34. [91D E] What is contemplated is the creation of a Reserve Fu nd in the relevant previous year irrespective of the result of the profit and loss account disclosed by the books of t he assessee. Mere book entries will suffice for creating such a Reserve Fund. The debit entries and the entries relating to the Reserve Fund have to be made before the profit and lo ss account is finally drawn up. That is a condition for secu r ing the benefit of development rebate. [89E F] West Laikdihi Coal Co. Ltd.
