S. K. DAS J.--- This appeal on a certificate of fitness granted by the High Court of Bombay raises a question of interpretation of sub-section (10) of section 35 of the Indian Income-tax Act, 1922. This sub-section is one of a group of sub-sections substituted or inserted in the said section by section 19 of the Finance Act, 1956 (18 of 1956). By section 28 of the said Finance Act, sub-section (10) of section 35 of the Income-tax Act, 1922, came into force on April 1, 1956. The short question before us is, whether on its true construction, sub-section (10) of section 35 applies in a case where a company declares dividends by availing itself wholly or partly of the amount on which a rebate of income-tax was earlier allowed to it under clause (i) of the proviso to Paragraph B of Part I of the relevant Schedules to the Finance Acts, when such dividends were declared prior to the coming into force of the sub-section, that is, prior to April 1, 1956.

The facts which have given rise to the appeal are these. The Ahmedabad Manufacturing and Calico Printing Co. Ltd. is the appellant before us. The appellant company was incorporated under the Indian Companies Act, 1866, and has its office at Ahmedabad. It carries on the business of manufacturing and selling cotton piece-goods and chemicals. For the assessment year 1952-53, the corresponding account year being the calendar year 1951, the appellant was assessed to income-tax and super-tax on a total income of Rs. 1,02,79,808 and was allowed a rebate of one anna per rupee on the undistributed profits of Rs. 36,62,776 under the first proviso to Paragraph B of Part I of the First Schedule to the Finance Act, 1952. The amount of rebate allowed was Rs. 2,28,924. For the assessment year 1953-54, the corresponding account year being the calendar year 1952, the appellant showed a book profit of Rs. 45,67,966, but was assessed to a loss of Rs. 5,98,353 on April 17, 1954. For the said calendar year 1952, the appellant declared a dividend of Rs. 19,32,000 on April 20, 1954. This dividend came out of the undistributed profits of the calendar year 1951 on which the appellant had been allowed a rebate.

On March 18, 1958, the Income-tax Officer, Special Circle, Ahmedabad, respondent No. 1 before us, issued a notice to the appellant calling upon the latter to show cause why action under sub-section (10) of section 35 should not be taken against the appellant by withdrawing the rebate allowed on the sum of Rs. 19,32,000. The appellant raised some objections, one of which was that sub-section (10) of section 35 did not apply to his case. The Income-tax Officer, however, held that sub-section (10) of section 35 applied and accordingly directed that the rebate allowed on the sum of Rs. 19,32,000 should be withdrawn, by recomputing the tax payable by the appellant. He ordered the issue of a demand notice for a sum of Rs. 1,20,750 which was the rebate allowed on Rs. 19,32,000. The Income-tax Officer passed this order on March 27, 1958.

Being aggrieved by that order, the appellant moved the High Court of Bombay by a writ petition filed on June 26, 1958. The main ground taken by the appellant was that sub-section (10) of section 35 did not apply to a case where dividend was declared, as in this case, before the coming into force of sub-section (10) of section 35. The High Court rejected this contention and dismissed the writ petition. The appellant then obtained a certificate of fitness and has preferred the present appeal in pursuance of that certificate.

We may now read some of the provisions of section 35 in so far as they are relevant for our purpose :

" 35. (1) The Commissioner or Appellate Assistant Commissioner may, at any time within four years from the date of any order passed by him in appeal or, in the case of the Commissioner, in revision under section 33A and the Income-tax Officer may, at any time within four years from the date of any assessment order or refund order passed by him on his own motion rectify any mistake apparent from the record of the appeal, revision, assessment or refund as the case may be, and shall within the like period rectify any such mistake which has been brought to his notice by an assessee : .........

(5) Where in respect of any completed assessment of a partner in a firm it is found on the assessment or reassessment of the firm or on any reduction or enhancement made in the income of the firm under section 31, section 33, section 33A, section 33B, section 66 or section 66A that the share of the partner in the profit or loss of the firm has not been included in the assessment of the partner or, if included, is not correct, the inclusion of the share in the assessment or the correction thereof, as the case may be, shall be deemed to be a rectification of a mistake apparent from the record within the meaning of this section, and the provisions of sub-section (1) shall apply thereto accordingly, the period of four years referred to in that sub-section being computed from the date of the final order passed in the case of the firm.

(6) Where the excess profits tax or the business profits tax payable by an assessee has been modified in appeal, revision or any other proceeding, or where any excess profits tax or business profits tax has been assessed after the completion of the corresponding assessment for income-tax (whether before or after the commencement of the Income-tax (Amendment) Act, 1953), and in consequence thereof it is necessary to re-compute the total income of the assessee chargeable to income-tax, such recomputation shall be deemed to be a rectification of a mistake apparent from the record within the meaning of this section, and the provisions of sub-section (1) shall apply accordingly, the period of four years referred to in that sub-section being computed from the date of the order making or modifying the assessment of such excess profits tax or business profits tax .....

(10) Where, in any of the assessments for the years beginning on the 1st day of April, of the years 1948 to 1955 inclusive, a rebate of income-tax was allowed to a company on a part of its total income under clause (1) of the proviso to Paragraph B of Part I of the relevant Schedules to the Finance Acts specifying the rates of tax for the relevant year, and subsequently, the amount on which the rebate of income-tax was allowed as aforesaid is availed of by the company, wholly or partly, for declaring dividends in any year, the amount or that part of the amount availed of as aforesaid, as the case may be, shall, by reason of the rebate of income-tax allowed to the company and to the extent to which it has not actually been subjected to an additional income-tax in accordance with the provisions of clause (ii) of the proviso to Paragraph B of Part I of the Schedules to the Finance Acts above referred to, be deemed to have been made the subject of incorrect relief under this Act, and the Income-tax Officer shall recompute the tax payable by the company by reducing the rebate originally allowed, as if the recomputation is a rectification of a mistake apparent from the record within the meaning of this section and the provisions of sub-section (1) shall apply accordingly, the period of four years specified therein being reckoned from the end of the financial year in which the amount on which the rebate of income-tax was allowed as aforesaid was availed of by the company wholly or partly for declaring dividends."

Speaking generally, section 35 deals with rectification of mistakes in circumstances detailed in the various sub-sections thereof and provides for orders consequent on such rectification. Sub-section (1) empowers the income-tax authorities to rectify mistakes apparent from the record in respect of certain orders passed by them. It provides that the Income-tax Officer concerned may at any time within four years from the date of any assessment order passed by him on his own motion rectify any mistake apparent from the record of the assessment. The power of rectification may be exercised subject to two conditions : (1) that there is a mistake apparent from the record of the assessment, and (2) that the order of rectification is made within four years from the date of the assessment sought to be rectified. Sub-section (5) deals with inclusion or correction of the income of a partner in a firm consequent upon assessment or reassessment of the firm of which he was a partner. Sub-section (6) deals with recomputation of total income of an assessee in consequence of modifications made in the excess profits tax or the business profits tax payable by an assessee subsequent to an assessment made under the Income-tax Act. These two sub-sections were considered by this court in two decisions to which we shall presently refer. They have been relied on by the appellant and have some bearing on the interpretation of sub-section (10). Sub-sections (2), (3), (4), (7), (8) and (9) are not relevant for our purpose and need not be referred to.

Now, we come to sub-section (10). It deals with a case where a rebate was allowed to a company on a part of its income (viz., undistributed profits) by virtue of the concessions given by the Finance Acts of 1948 to 1955 : this is clear from the first part of the sub-section. The second part states the condition in which, or rather the crucial event on the happening of which, the rebate granted to a company is deemed to have been given by a mistake apparent from the record : this condition or crucial event is the declaration of dividends by the company out of the amount in whole or in part, on which rebate was earlier granted to it. The third and operative part states that on the happening of the crucial event, the amount on which rebate was granted and which has been subsequently utilised for declaring dividends shall be deemed to have been made the subject of incorrect relief under the Act and the Income-tax Officer shall recompute the tax payable by the company by reducing the rebate originally allowed as if the recomputation is a rectification of a mistake apparent from the record within the meaning of the section. The fourth and last part introduces a period of limitation of four years, the four years being reckoned not from the date of the order passed as in sub-section (1), but from the end of the financial year in which the amount on which rebate of income-tax was allowed was availed of by the company wholly or partly for declaring dividends. This, in brief, appears to be the scheme of sub-section (10) of section 35.

Now, the argument on behalf of the appellant is this. Like sub-section (5) of section 35, sub-section (10) affects a vested right, namely the right to a rebate of income-tax on a part of the total income of the company under clause (i) of the proviso to Paragraph B of Part I of the relevant Schedules to the Finance Acts of 1948 to 1955, and the further right to declare dividends out of the undistributed profits of the previous year. Under the well-settled rules of statutory construction, no statute which impairs an existing right or obligation except as regards a matter of procedure, shall have a retrospective operation unless such a construction appears very clearly in the terms of the Act or arises by necessary and distinct implication. Put differently, a statute is not to be construed to have a greater retrospective operation than its language renders necessary ; and it is submitted that " the general rule is that all statutes other than those which are merely declaratory, or which relate only to matters of procedure or of evidence are prima facie prospective ; and retrospective effect is not to be given to them unless by express words or necessary implication, it appears that this was the intention of the legislature " and " it is a corollary of this general presumption against retrospection that, even when a statute is intended to be to some extent retrospective, it is not to be construed as having a greater retrospective effect than its language renders necessary " (Halsbury's Laws of England, volume 36, third edition, page 423 and page 426). The argument on behalf of the appellant is that by section 28 of the Finance Act, 1956, sub-section (10) has undoubtedly retrospective effect from April 1, 1956 ; but the language of the sub-section does not expressly, nor by necessary implication, show that it has any greater retrospective effect. It is pointed out that, on the contrary, where the legislature wanted a particular sub-section to have greater retrospective effect, it had said so, e.g., in sub-section (6). It is also pointed out that sub-section (5) of section 35 was inserted by the Indian Income-tax (Amendment) Act, 1953, and by section 1(2) of the said Act it came into force on April 1, 1952. Where the legislature wanted to give greater retrospective effect to particular provisions, it said so in sections 3(2), 7(2) and 30(2) of the said Act. That being the position, the argument on behalf of the appellant is that we should not give any greater retrospective effect to sub-section (10) of section 35 than what has been done by section 28 of the Finance Act, 1956. Learned counsel for the appellant has strongly relied on the decision of this court in Income-tax of Officer v. S. K. Habibullah wherein with regard to sub-section (5) of section 35 it was held that the sub-section was not declaratory of the pre-existing law nor a matter relating to procedure but affected vested rights and must be deemed to have come into force only from April 1, 1952 ; therefore the Income-tax Officer had no jurisdiction under the said sub-section to rectify the assessment of a partner consequent on the assessment of the firm in cases where the firm's assessment was completed before April 1, 1952. The argument of the learned counsel for the appellant is that the same principle must apply in the present case and sub-section (10) of section 35 does not apply to a case where dividend was declared by the company before the date of the coming into force of the sub-section namely, April 1, 1956.

The second part of the argument of the learned counsel for the appellant is that there is no real difference in language between the two sub-sections, sub-section (5) and sub-section (10) of section 35. In both cases a rectification or correction is made by reason of a subsequent event ; in sub-section (5) the subsequent event is the assessment of the firm which discloses the inaccuracy in the earlier assessment of a partner ; in sub-section (10) the subsequent event is the declaration of dividend out of the amount on which a rebate was earlier granted. It is pointed out that in their true scope and effect, the two sub-sections stand on the same footing. Sub-section (10) further makes it clear, that by a legal fiction that which was correct at the time when it was made is rendered incorrect after the coming into force of the sub-section. The sub-section states clearly : "...shall, by reason of the rebate of income-tax allowed to the company ... be deemed to have been made the subject of incorrect relief under this Act, and the Income-tax Officer shall recompute the tax payable by the company by reducing the rebate originally allowed..." This language, it is argued, is clearly prospective and does not justify the carrying of the legal fiction to a period earlier than April 1, 1956.

As against these arguments, learned counsel for the respondent has contended that the language of sub-section (10) is different from that of sub-section (5) and the principle laid down by this court in S. K. Habibullah's case cannot be applied to the present case. Alternatively, he has argued that the decision is incorrect and should be reconsidered by us. The argument of learned counsel for the respondent is that sub-section (10) by necessary implication has a greater retrospective effect than what is laid down by section 28 of the Finance Act, 1956. He points out that the first part of the sub-section talks of the assessments made for any of the years beginning on April 1, 1948, to April 1, 1955, when a rebate of income-tax was, allowed ; then the second part refers to the subsequent declaration of dividend by the company in any year. Learned counsel for the respondent has emphasised the expression " in any year " and has submitted that this shows that the intention was to take in a declaration of dividend made even earlier than April 1, 1956. According to him, the only effect of section 28 of the Finance Act, 1956, is that the Income-tax Officer can take action only after April 1, 1956, but the language of the sub-section does not justify the conclusion that the legal fiction created by it must be restricted to the declaration of dividends on or after April 1, 1956.

We have carefully considered these arguments. The language of sub-section (10) of section 35 is perhaps not as clear as one might wish, it to be. There is no doubt, however, that the sub-section affects vested rights and should not be given a greater retrospective operation than its language renders necessary. Even though the sub-section is to a certain extent retrospective, and section 28 of the Finance Act, 1956, in express terms makes it retrospective from April 1, 1956, it is blear to us that there is nothing in the language of the sub-section which would justify the inference that the legislature intended to carry the legal fiction created by the sub-section to a period earlier than the date on which the sub-section came into force. The maxim applicable in such cases is that even in construing a section which is, to a certain extent retrospective, the line is reached at which the words of the section cease to be plain. We are further of the opinion that when the first part of the sub-section refers to the assessments for the years 1948 to 1955, it merely refers to the period during which the rebate provisions were in force. It is not disputed before us that the rebate provisions came into force from the Finance Act of 1948 and ended with the Finance Act of 1955. The first part, therefore, is merely a reference to the period during which the rebate provisions were in force. It is indeed true that in the second part of the sub-section the expression used is " declaring dividends in any year " and this has to be read in conjunction with the word " subsequently " which can only mean subsequent to the allowance of the rebate. But in the very same part, it is further stated that the declaration of dividend in any year shall by reason of the rebate, be deemed to have made the amount on which the rebate was granted, the subject of incorrect relief etc. This language which creates the legal fiction is clearly prospective and shows that what was correct at the time when the rebate was granted is rendered incorrect on the happening of the crucial event after the coming into force of the sub-section, and by the express terms of section 28 of the Finance Act, 1956, the sub-section comes into force on April 1, 1956. We are unable, therefore, to agree with the learned counsel for the respondent that the language of sub-section (10) by necessary implication takes the legal fiction back to a period earlier than April 1, 1956. In coming to this conclusion, we have kept in mind the principle that a statute does not necessarily become retrospective because a part of the requisites for its action is drawn from a time antecedent to its passing.

Furthermore, we see no reason why the principle laid down in S. K. Habibullah's case, will not apply in the present case nor are we satisfied that that decision with regard to sub-section (5) of section 35 was incorrect. We may point out, however, that in Second Additional Income-tax Officer v. Atmala Nagaraj this court went a step further and held that sub-section (5) of section 35 was not applicable to cases where the assessment of the partner was completed before April 1, 1952, even though the assessment of the firm was completed after April 1, 1952. Learned counsel for the appellant frankly conceded before us that he did not wish to go as far as that and contend that even in a case where a declaration of dividend was made after April 1, 1956, sub-section (10) would not apply ; because that would make sub-section (10) unworkable. The decision in Second Additional Income-tax Officer v. Atmala Nagaraj, may perhaps require reconsideration as to which we need not express any final opinion now ; but so far as this case is concerned we see no reason why the principle in S. K. Habibullah's case will not apply. The principle is simply this. A statute which is not declaratory of a pre-existing law nor a matter relating to procedure but affects vested rights cannot be given a greater retrospective effect than its language renders necessary, and even in construing a section which is to a certain extent retrospective, the line is reached at which the words of the section cease to be plain. These are well-settled principles, and there is no reason to doubt their accuracy.

For the reasons given above, we would allow the appeal, set aside the order and judgment of the High Court and quash the order of the Income-tax Officer dated March 27, 1958, and the notice of demand dated March 28, 1958. The appellant will be entitled to its costs throughout.

SARKAR J.--- In its assessment to income-tax for the year 1952-53, the appellant, a company, had been granted under the provisions of the Finance Act, 1952, a rebate on a portion of its profits of the previous year, that is, 1951, which it had not distributed as dividends to its shareholders. In the next assessment year 1953-54, the appellant used a part of the aforesaid undistributed profits for declaring dividends. As the law then stood, nothing could be done by the revenue authorities to withdraw the rebate earlier granted on the ground of the profits being utilised in declaring dividends in a later year. From April 1, 1956, however, there was a change in the law as sub-section (10) of section 35 of the Income-tax Act, 1922, was brought into force then. By an order made on March 27, 1958, under that sub-section, the terms of which I will set out presently, the aforesaid rebate was withdrawn and the appellant was called upon to refund it. The appellant then applied to the High Court at Bombay for a writ to quash the order of March 27, 1958, on the ground that sub-section (10) was not applicable to the facts of this case for reasons which I will later state. That application was dismissed. This appeal is against this decision of the High Court at Bombay dismissing the application.

Now sub-section (i) of section 35 of the Income-tax Act was enacted by the Finance Act of 1956 and it was given effect from April 1, 1956. That sub-section, in so far as it is necessary to state for the purpose of this case, provides that where in any of the assessment years 1948-49 to 1955-56, a rebate of income-tax was allowed to a company under the Finance Act prevailing in that year on a part of its, total income " and subsequently the amount on which the rebate of income-tax was allowed as aforesaid is availed of by the company, wholly or partly, for declaring dividends in any year ..... the Income-tax Officer shall recompute the tax payable by the company by reducing the rebate originally allowed ". The sub-section in substance permits a rebate duly allowed in any year before it came into force to be withdrawn if " subsequently " the amount on which the rebate was allowed " is availed of for declaring dividends in any year ".

The appellant contends that the sub-section does not apply unless the amount on which the rebate was granted is availed of for declaring dividends after the sub-section had come into force, that is, after April 1, 1956, and, therefore, it does not apply to the present case. It is said that if it were not so, the sub-section would be given a retrospective operation and the rule is that it is to be presumed that a statute dealing with substantive rights is not to have such operation. The case of Income-tax Officer, Madras v. S. K. Habibullah, was cited in support of this contention.

I will assume that if the sub-section were applied to a case like the present, it would affect a vested right. The rule no doubt is that a statute is presumed not to be so. But this rule does not apply if the language of the statute indicates an intention to give it a retrospective operation. It seems to me that sub-section (10) uses language which indicates sufficiently clearly that it was intended to be applied where the amount on which rebate had been obtained was availed of for declaring dividends before the sub-section came into force, that is to say, to have a retrospective operation. It says, " subsequently the amount on which the rebate of income-tax was allowed as aforesaid is availed of for declaring dividends in any year ". There is no doubt that the words " subsequently " and " in any year " mean in, any year subsequently to the year in which the rebate was granted. They would, therefore, clearly include a year before the sub-section came into force. But it is said that these words should in view of the rule be read as not including a year before the sub-section came into force as they also include years subsequent to the coming into force of the sub-section and are therefore ambiguous.

I am unable to accept this contention. I find no ambiguity. If the intention was that the sub-section would apply only when the amount was availed of for declaration of dividends after it was enacted then the words " subsequently " and " in any year " were wholly unnecessary. Without these words the sub-section would have read, " and the amount is availed of for declaring dividends ". There would then be no doubt that it was intended to operate only prospectively. But the legislature used some more words. It must have done so with some purpose. What that purpose was if it was not to give the sub-section a retrospective operation, I fail to see. I am unable to read the words " subsequently " and " in any year " as otiose and as indicating no different intention. Therefore, it seems to me that the language of the sub-section plainly requires it to have a retrospective operation. The sub-section is properly applicable to this case.

There is another consideration leading me to the view that the presumption against retrospective operation does not arise here. It was said in Pardo v. Bingham that it was not an invariable rule that a statute could not have a retrospective operation unless so expressed in its very terms, and that it was necessary to look to the general scope and purview of the statute and at the remedy sought to be applied and consider what was the former state of the law and what it was that the legislature contemplated. It is quite plain that in providing for the grant of rebate on undistributed profits by the Finance Acts 1948 to 1955 the legislature wanted to encourage the employment of the profits made in a business in the business itself. The object presumably was to expand the industries of the country. This involved a long term employment of the profits in the business. It could not have been the intention of the legislature to grant rebate when a company only kept the profits for a short time with itself and having earned the rebate distributed the profits without the industry having had any real benefit of them. I think I should state here that the provisions for the grant of rebate did not require that dividend was not to be declared at all. The object was to encourage a reasonable division of the profits between the shareholders and the industry. Allowance of rebate was provided for on that part of the profits which, was left for employment in the industry after reasonable dividends had been distributed to the shareholders. The rebate was allowed on, a graded scale depending on the amount of profits which was not distributed as dividends.

Now the system of granting rebates started in 1948-49. It was, stopped in 1955-56. The sub-section was brought into force on April 1, 1956, that is, seven years after the system had first been started. The sub-section provided for withdrawal of the rebate when the amount on which it had been granted was availed of in declaring dividends. It is fairly clear from this that the legislature did not approve of these amounts being utilised in declaration of dividends. It is also not too much to suppose that there had been many previous cases of such utilisation of profits for if it had not happened earlier, there is no reason to think that the legislature anticipated the evil happening in future and passed the law to stop it. In view of the large number of years that had passed between the time when the allowance of rebate commenced and the time when the sub-section was brought into force, it can be imagined that a very large number of cases of distribution of profits on which rebate had been allowed, had already taken place. I find it difficult to think that many cases remained after April 1, 1956, where a company which intended to utilise the amounts on which rebate had been granted in the declaration of dividends, had not already done so.

There is no dispute that by sub-section (10) the legislature intended to penalise a case. where subsequent to its enactment, the amount on which rebate had been granted was utilised in declaration of dividends. Now is there any reason to think that the legislature did not want to impose the penalty also on those who had earlier utilised the amount in declaration of dividends? There was no special merit in these latter cases. And I also think that they formed -the majority of the cases. The grant of rebate having been stopped after March 31, 1956, there was no occasion to provide for cases of such grant thereafter. All these circumstances lead me to the view that the intention of the legislature was to penalise the cases of utilisation of amounts on which rebate had been granted in payment of dividends which had happened before the sub-section came into force. The remedy which the sub-section provided would largely fail in any other view. The general scope and purview of the sub-section and a consideration of the evil which it was intended to remedy lead me to the opinion that the intention of the legislature clearly was that the sub-section should apply to the facts that we have in this case.

As to S. K. Habibullah's case, I do not think that much assistance can be had from it. It applied the rule of presumption against a statute having a retrospective operation---as to which rule, of course, there is no dispute---to sub-section (5) of section 35. Now cases on the construction of one statute are rarely of value in construing another statute, for each case turns on the language with which it is concerned and statutes are not often expressed in the same language. The language used in sub-sections (5) and (10) seem to me to be wholly different. There is nothing in S. K. Habibullah's case to indicate that in the opinion of the learned judges deciding it there were any words which would indicate that sub-section (5) was to have a retrospective operation. In my view, sub-section (10) contains such words. Furthermore, I do not find that the other considerations to which I have referred arose for discussion in that case. In my view, the two cases are entirely different.

I, therefore, think that sub-section (10) of section 35 properly applies to this case. In my view, the appeal should be dismissed with costs.

HIDAYATULLAH J.--- This is an appeal by an assessee with certificate under article 133(1)(c) of the Constitution from the judgment and order of the High Court of Bombay dismissing the assessee-company's petition under article 226 of the Constitution which challenged an order under section 35(10) of the Income-tax Act rectifying the earlier assessment and sought a writ or writs to prohibit the income-tax authorities from giving effect to that order.

The assessee (the Ahmedabad Manufacturing & Calico Printing Co. Ltd.) is a public limited company carrying on business of manufacture of cotton piece-goods and chemicals. The year of account of the assessee-company is the calendar year. In the assessment year 1952-53, corresponding to the calendar year 1951, the appellants were assessed on January 31, 1953, on a total income of Rs. 1,02,79,808. The assessee-company was allowed a rebate of one anna per rupee amounting to Rs. 2,28,924 on the undistributed profits of Rs. 26,62,776 ,under the first proviso to Paragraph B of Part 1 of the First Schedule to the Finance Act, 1952. For the assessment year 1953-54 (account year calendar year 1952) the books of the assessee-company showed a profit of Rs. 45,67,966. That profit became a loss of Rs. 5,98,353 after deductions like depreciation etc., were allowed. In spite of there being a loss, the assessee-company declared on April 20, 1953, a dividend of Rs. 19,32,000 for the year of account 1952.

The Income-tax Officer, by an order dated March 18, 1958, called upon the assessee-company to show cause why action under section 35(10) of the Income-tax Act should not be taken to recall a proportionate part of the rebate because in his opinion the entire dividend of Rs. 19,32,000 came out of the undistributed profits of the calendar year 1951, on which the appellant had received a rebate. The assessee-company objected saying that the 10th sub-section of section 35 was introduced as from April 1, 1956, and could not operate on an assessment which had become final before April 1, 1956, from which date sub-section (10) was retrospectively applied. The objection was not accepted and the Income-tax Officer held that dividend paid in the year 1952 came out of the undistributed profits of 1951 and a tax proportionate to the sum of Rs. 19,32,000 amounting to Rs. 1,20,750 was leviable. The assessee-company filed a petition under article 226 of the Constitution. That application was heard along with another filed by the New Shorrock Spg. & Mfg. Co. Ltd., in which the leading judgment was delivered by the High Court. Following the decision in the New Shorrock Spg. & Mfg. Co's case, the High Court dismissed the assessee-company's petition with costs. The High Court, however, certified the case as fit for appeal and hence the present appeal.

Section 35 deals with rectification of mistakes. Prior to 1939, rectification of any mistake apparent from the record could be made within one year of the order of assessment but by the Indian Income-tax (Amendment) Act, 1939 (7 of 1939) the period of four years was substituted for one year in the first sub-section. That sub-section omitting the provisos read at all material times as follows :

" The Commissioner or Appellate Assistant Commissioner may, at any time within four years from the date of any order passed by him in appeal or, in the case of the Commissioner, in revision under section 33A and the Income-tax Officer may, at any time within four years from the date of any assessment order or refund order passed by him, on his own motion rectify any mistake apparent from the record of the appeal, revision, assessment or refund, as the case may be, and shall within the like period rectify any such mistake which has been brought to his notice by an assessee."

It must be noticed that the time-limit started from the date of the order of assessment which was to be rectified.

In 1953, by section 19 of the Indian Income-tax (Amendment) Act, 1952 (25 of 1953), sub-section (5) (among others) was added as from April 1, 1952. That sub-section reads as follows :

" (5) Where in respect of any completed assessment of a partner in a firm it is found on the assessment or reassessment of the firm or on any reduction or enhancement made in the income of the firm under section 31, section 33, section 33A, section 33B, section 66 or section 66A that the share of the partner in the profit or loss of the firm has not been included in the assessment of the partner or, if included, is not correct, the inclusion of the share in the assessment or the correction thereof, as the case may be, shall be deemed to be a rectification of a mistake apparent from the record within the meaning of this, section, and the provisions of sub-section (1) shall apply thereto accordingly, the period of four years referred to in that sub-section being computed from the date of the final order passed in the case of the firm."

It must be noticed that under this amendment time-limit started from the date of the final order passed in the case of the firm though the rectification is to be made in the assessment of the partners of the firm.

By section 19 of the Finance Act, 1956, sub-section (10) (among others) was added as from April 1, 1956. That sub-section reads as follows :

" (10) Where, in any of the assessments for the years beginning on the 1st day of April, of the years 1948 to 1955 inclusive, a rebate of income-tax was allowed to a company on a part of its total income under clause (i) of the proviso to Paragraph B of Part I of the relevant Schedules to the Finance Acts specifying the rates of tax for the relevant year, and subsequently the amount on which the rebate of income-tax was allowed as aforesaid is availed of by the company, wholly or partly, for declaring dividends in any year, the amount or that part of the amount availed of as aforesaid, as the case may be, shall, by reason of the rebate of income-tax allowed to the company and to the extent to which it has not actually been subject to an additional income-tax in accordance with the provisions of clause (ii) of the proviso in Paragraph B of Part I of the Schedules to the Finance Acts above referred to, be deemed to have been made the subject of incorrect relief under this Act, and the Income-tax Officer shall recompute the tax payable by the company by reducing the rebate originally allowed, as if the recomputation is a rectification of a mistake apparent from the record within the meaning of this section and the provisions of sub-section (1) shall apply accordingly, the period of four years specified therein being reckoned from
