Summarize the following court judgment. Appeals Nos. 314 to 322 of 1966 Appeals by special leave from the judgment and order dated April 25	 1963 of the Allahabad High Court in Special Appeals Nos. 662	 663	 679	 664	 665	 667	 666	 669 and 671 of 1962 respectively. S.K. Aiyer and R.N. Sachthey	 for the appellant (in all the appeals. ) J.P. Goyal	 Sobhag Mal Jain and P.N. Pachauri	 for the respondents (in all the appeals ). The Judgment of the Court was delivered by Ramaswami	 J. In these appeals which have been heard together a common question of law arises for determination	 that is	 whether the. expression "any person who has not hitherto been assessed" in section 18A(3) of the Income Tax Act	 1922 (hereinafter called the Act) after the Income Tax Amendment Act (Act 67 of 1949) should be interpreted so as to include a person who has only been provisionally assessed under section 23B of that Act. The respondents in these appeals are four persons Mani Ram	 Jagmohan	 Kishandas	 Bhagirathmal partners of Shri 726 Kishan Das	 DhankUtti	 Kanpur. They were members of a joint Hindu farmily carrying on business until they became divided in the middle of assessment year 1953 54. Thereafter they were carrying on the business in partnership. For the year 1953 54	 the firm submitted a return showing loss. But in the next succeeding year 1954 55 it disclosed a profit and submitted a return. All the four partners filed returns individually on 27 9 1954 and they were provisionally assessed on their returns on 14 10 1954. But the regular assessment was made for this year only on 27 2 1958. The 	firm continued to make profits in the subsequent years 1955 56	 1956 57	 1957 58 and 1958 59 and the partners filed returns for their income for each of these years and were regularly assessed for these years under section 23 sometime after 27 2 1958. The assessment order for 1958 59 was in fact made on 19 2 1959. It is not disputed that none of the four partners sent any estimate of the tax payable on their income as required by section 18A of the Income Tax Act	 1922 or pay the tax in advance. Therefore	 the Income Tax Officer	 Kanpur while assessing them under section 23 of the Act held that they were liable to pay interest under section 18A(8) and determined the amount payable by each in respect of each of the years on the basis of the income found taxable in the regular assessment. In addition	 he applied the provisions of section 18A(9)(b) and imposed a penalty for each year of assessment by virtue of section 28 read with section 18A(9) (b) of the Act. The four partners preferred appeals to the Appellate Assistant Commissioner on the ground that the levy of interest and penalty was unauthorised. But the appeals were dismissed. The partners applied in revision to the Commissioner of Income Tax under section 33A(2)	 but the revision applications were dismissed. The respondents thereafter moved the Allahabad High Court for grant of a writ to quash the orders of the Income Tax Officer and of the Appellate Assistant Commissioner in appeal. The applications for writ were allowed by Mr. Justice S.C. Manchanda who held that section 18A(3) could not apply to the facts of the case as there had been a provisional assessment under section 23B in the year 1954. Against the decision of the Single Judge the appellants preferred appeals before the Division Bench. These appeals were dismissed by a common judgment of the Allahabad High Court dated 25th March	 1963. The present appeals are brought to this Court by special leave from the judgment of the Allahabad High Court dated 25th March	 1963 in the batch of appeals affirming the judgment of the Single Judge dated 25th May	 1956 in C.W.M. No. 1591 of. 1962 and the connected writ applications. It is necessary at this stage to set out the provisions of seetions 18A	 23 and 23B of the Income Tax Act	 1922 as they stood at the material time: 727 "18A (1) (a). In the case of income in respect of which provision is not made under section 18 for deduction of income tax at the time of payment	 the Income Tax Officer may	 on or after the 1st day of April in any financial year	 by order in writing	 require an assessee to pay quarterly to the credit of the Central Government on the 15th day of June	 15th day of September	 15th day of December and 15th day of March in that year	 respectively	 an amount equal to onequarter of the income tax and super tax payable on so much of such income as is included in his total income of the latest previous year in respect of which he has been assessed	 if that total income exceeded the maximum amount not chargeable to tax in his case by two thousand five hundred rupees. Such income tax and super tax shall be calculated at the rates in force for the financial year in which he is required to pay the tax	 and shall bear to the total amount of income tax and super tax so calculated on the said total income the same preparation as the amount of such inclusions bears to his total income or	 in cases where under the provisions of sub section (1) of section 17 both income tax and super tax are chargeable with reference to the total world income	 shall bear to the total amount of income. tax and super tax which would have been payable on his total world income of the said previous year had it been.his total income the same proportion as the amount of such inclusions bears to his total world income. (2) (3) Any person who has not hitherto been assessed shall	 before the 15th day of March in each financial year	 if his total income of the period which could be the previous year for an assessment for the. financial. year next following is likely to exceed the maximum amount not chargeable to tax in his case by two thousand five hundred rupees	 send to the Income Tax Officer an estimate of the tax payable by him on. that part of his income to which the provisions of section 18 do not apply of the said previous year calculated in the manner laid down in sub section (1)	 and shall pay the amount	 on such of the dates specified in that subsections as have not expired	 by installments which may be revised according to the proviso to sub section (2). (4) (5) Sup. C.I/68 16 728 (6) Where in any year an assessee has paid tax under sub section (2) or sub section (3) on the basis his own estimate	 and the tax so paid is less than eighty per cent of the tax determined on the basis of the regular assessment	 so far as such tax relates to income to which the provisions of section 18 do.	 not apply and so far as it is not due to variations in the rates of tax made by the Finance Act enacted for the year for which the regular assessment is made	 simple interest at the rate of Six per cent per annum from the 1 st day of January in the financial year in which the tax was paid up to the date of the Said regular assessment shall be payable by the assessee upon the amount by which the tax so paid falls short of the said eighty per cent. (7) (8) Where on making the regular assessment	 the Income Tax Officer finds that no payment of tax has been made in accordance with the foregoing provisions of this section	 interest calculated in the manner laid down in sub section (6) shall be added to the tax as determined on the basis of the regular assessment. (9 ) If the Income Tax Officer	 in the course of any proceedings in connection with the regular assessment	 is satisfied that any assessee (a) has furnished under sub section (2) of subsection (3 ) estimates	 of the tax payable by him which he knew or had reason to believe to be untrue	 or (b) has without reasonable cause failed to comply with the provisions. of sub section (3)	 the assessee shall be deemed	 in the case referred to in clause (a)	 to have deliberately furnished inaccurate particulars of his income	 and in the case referred to in clause (b) to have failed to furnish the return of his total income; and the provisions of section 28	 so far as may ;be	 shall apply accordingly. (1) If the Income Tax Officer is satisfied without requiring the presence of the assessee or the production by him of any evidence that a return made under section 22 is correct and complete	 he shall assess the total income of the assessee	 and shall determine the sum payable by him on. the basis of such return. 729 (2) If the Income Tax Officer is not satisfied without requiring the presence of the person who made the return or the production of evidence that a return made under section 22 is correct and complete	 he shall serve on such person a notice either to attend at the Income Tax Officer 's Office or to produce	 or to cause to be there produced	 any evidence on which such person may rely in support of the return. (3 ) On the day specified in the notice issued under sub section (2)	 or as soon afterwards as may be	 the Income Tax Officer	 after hearing such evidence as such person may produce and such Other evidence as the Income Tax Officer may require	 on specified points shall	 by an order in writing	 assess the total income of the assessee and determine the sum payable by him on the basis of such assessment. (4) If any person fails to make the return required by any notice given under sub section (2) of section 22 and has not made a return or a revised return under sub section (3) of the same section or fails to comply with all the terms of a notice iSsued under sub section (4) of the same section or	 having made a return	 fails to comply with all the terms of a notice issued under sub section (2) of this section	 the Income Tax Officer shall make the assessment to the best of his judgment and determine the sum payable by the assessee on the basis of such assessment and	 in the case of a firm	 may refuse to register it or may cancel its registration if it is already registered. 23B (1 ) The Income Tax Officer may	 at any time after the receipt of a return made under section 22 proceed to make in a summary manner	 a provisional assessment of the tax payable by the assessee	 on the basis of his return and the accounts and documents	 if any	 accompanying it	 after giving due effect to (i) the allowance referred to in paragraph (b) of the proviso to clause (vi) of sub section (2) of section 10	 and (ii) any loss carried forward under sub section (2) of section 24. (2) A partner of a firm may be provisionally assessed under sub section ( 1 ) in respect of his share in the firm 's income	 profits and gains; if its return has been received	 although the return of the parroter himself may not have been received	 730 (3) A firm may be provisionally assessed under sub section (1) as if it were an unregistered firm	 unless the firm fulfils such conditions as the Central Government may	 by notification in the official Gazette	 specify in that behalf. (4) There shall be no right of appeal against a provisional assessment made under sub section (1). (5) For the avoidance of doubt	 it is hereby declared that the provisions of section 45 (except the first proviso) and section 46 apply in relation to any tax payable in pursuance of a provisional assessment made under sub section (1) as if it were a regular assessment made under section 23. (6) Income tax paid or deemed to have been paid under section 18 or section 18A in respect of any income provisionally assessed under sub section (1)	 shall be deemed to have been paid towards the provisional assessment. (7) After a regular assessment has been made under section 23	 any amount paid or deemed to have been paid towards a provisional assessment made under sub section (1)	 shall be deemed to have been paid towards the regular assessment; and where the amount paid or deemed to have been paid towards the provisional assessment	 exceeds the amount payable under the regular assessment	 the excess shall be refunded to the assessee. ( 8 ) Nothing done or deferred by reason or in consequence of any provisional assessment made under this section shall prejudice the determination on the merits	 of any issue which may arise in the course of the regular assessment under section 23". It was argued on behalf of the appellants that a mere provisional assessment under section 23B of the Act will not satisfy the requirements of section 18A(1) of the Act because the language of section 18A(1) shows that the provisions of that subsection only apply when the amount of tax to be deposited in advance is determined on the basis of the assessee 's total income of previous year to which he has been assessed. It was contended that in the case of a provisional assessment under section 23B of the Act	 there is no computation of the total income of the previous year and that under section 23B of the Act all that is done is to determine provisionally the income tax payable on the 731 basis of the return filed without properly going through the process of assessing the total taxable income. It is not possible to accept this argument because even when the tax is provisionally assessed	 there necessarily has to be a determination of the total income of the assessee. The only difference is that under section 23 the total income is determined after the Income Tax Officer has satisfied himself fully about the correctness of the return flied by taking steps	 if necessary	 under sections 22(4) and 23(2) of the Act. In the case of a provisional assessment under section 23B of the Act	 the powers under sections 22(4) and 23(2) of the Act are not to be exercised and the Income Tax Officer has to determine the tax on the basis of the return filed by the assessee after taking into consideration the accounts and documents available	 if any	 and after giving effect to certain allowances and losses. In other words	 what the Income Tax Officer has to do is to assess provisionally the total income of the assessee and thereafter he has to determine the tax payable on the basis of that provisionally assessed income. The argument was next stressed that section 18A(1) was introduced into the Act when section 23B did not exist at all and consequently no inference should be drawn that the word "assessed" used in section 18A(1) was meant to cover a provisional ' assessment under section 23B of the Act also. In other words	 the argument of the appellants was that when the word "assessed" was used in section 18A(1) of the Act Parliament could not have contemplated that this word would cover a case of provisional assessment as no section relating to provisional assessment existed in the Act at that time. We are unable to accept this argument as correct. It should be noticed that the Parliament introduced certain amendments in section 18A of the Act consequential to the introduction of section 23B of the Act. There is a reference to the provisional assessment made under section 23B in sub section (5) of section 18A	 but Parliament took no step to restrict the meaning of the word "assessed" in. section 18A(3) so as to exclude a reference to provisional assessment under section 23B of the Act. If Parliament contemplated that section 18A(3) should apply only in the case of a "regular assessment"	 there was no reason why it did not put 'some qualifying words or expressions before or after the word 	assessed in section 18A( 1 ). It is not possible to accept the submission of the appellants that Parliament in fact intended to bring about such a decision but only accidentally omitted to do so. On the other hand	 the language of section 18A( 1 ) as it stands	 can only lead to interpretation that the provisions contained in it Would become applicable whenever a person has been assessed whatever be the nature of the assessment whether it be a regular assessment or a provisional assessment. 732 It is important to notice that in section 18A ( 1 ) the expression "assessed" is used without any qualification or restriction as to whether the assessment should be a regular assessment or any other type of assessment under the Act. It is also manifest that in section 18A sub section (5) the two expressions "provisional assessment" and "regular assessment" are expressly mentioned. The expression "regular assessment" is also repeatedly used in section 18A	 sub section 6	 7	 8 and 9. We see	 therefore	 no warrant for restricting the meaning of the word "assessed" in section 18A(1) so as to include only a "regular assessment" under section 23 of the Act. There is no reason why Parliament did not add the word "regularly" in the sub section so as to qualify the word "assessed". Since there is no such qualification. the word "assessed" in section 18A(3) should be read in its ordinary sense as including every kind of assessment including a provisional assessment under section 23B of the Act. In the last place	 counsel on behalf of the appellants referred to the language of sections 210 and 212(3) of the Income Tax Act	 1961 which state: "210. Order by Income Tax Officer : (1) Where a person has been previously assessed by way of regular assessment under this Act or under the Indian Income Tax Act	 1922 ( 11 of 1922 )	 the Income Tax Officer may	 on or after the 1st day of April in the financial year	 by order in writing	 require him to pay to the credit of the Central Government advance tax determined in accordance with the provisions of sections 207	 208 and 209. (2) The notice of demand issued under section 156 in pursuance of such order shall specify the installments in which the advance tax is payable under section 211. (3) If	 after the making of an order by the Income Tax Officer under this section and before the 15th day of. February. of the Financial year tax is paid by the assessee under section 140 A or a regular assessment or a provisional assessment under section 141 of the assessee or of the registered firm of which he is a partner is made in respect of a previous year later than that referred to in the order of the Income Tax Officer	 the Income Tax Officer may make an amended order queering the assessee to pay in one installment on the specified date. or in equal instalments on the specified dates. if more than one	 falling after the date of the amended order	 the advance tax computed on the basis 733 of the total income on which tax has been paid under section 140 A or in respect of which the regular assessment or	 the provisional assessment aforesaid has been made as reduced by the amount	 if any	 paid in accordance with the original order 213. Estimate by assessee	 ( 1 ) . . (3 ) Any person who has not previously been assessed by way of regular assessment under this Act or under the Indian Income Tax Act	 1922 (11 of 1922) shall	 before the first day of March in each financial your	 if his total income exclusive of capital gains of the period which would be the previous year for the immediately following assessment year is likely to exceed the maximum amount not chargeable to income tax in his case by two thousand five hundred rupees	 send to the Income Tax Officer (i) an estimate of the total income exclusive of capital gains of the said previous year; (ii) an estimate of the advance tax payable by him calculated in the manner laid down in section 209: and shall pay such amount as accords with his estimate	 on such of the dates specified in section 211 as have not expired	 by instalments which may be revised according to sub section (2)". The argument was that these sections apply to a case of a regular assessment and the enactment of these sections should be ' treated as a Parliamentary exposition of section 18A(3) of the earlier Act as referring only to a case of regular assessment. We are unable to accept this argument as correct. There is nothing in 1961 Act to suggest that Parliament intended to explain the meaning or clear up doubts about the meaning of the word "assessed" in section 18A(3) of the earlier Act. Generally speaking	 a subsequent Act of Parliament affords no useful guide to the meaning of another Act which came into existence before the later one was ever framed. Under special circumstances	 the law does however admit of a subsequent Act to be resorted to for this purpose but the conditions under which the later Act may be resorted for the interpretation of the earlier Act are strict; both must be laws on the same subject and the part of the earlier Act which it is sought to construe must be ambiguous and capable of different meanings. For example	 in Kirkness (Inspector of Taxes) vs John Hudson & Co. Ltd.(1) it was held by the (1) 734 House of Lords that the ordinary meaning of the word "sale" importing a consensual relation is to be attributed to the use of it in the context of section 17(1)(a) of the Act of 1945. Since there was no ambiguity in the section	 it was not permissible to seek guidance in its construction from later Finance Acts	 although it was directed by Parliament to be construed as one with them. At page 714 of the Report Viscount Simonds states: "I have looked at the later Acts to which the Attorney General referred to in order to satisfy myself that they do not contain a restrospective declaration as to the meaning of the earlier Act. They clearly do not	 and I do not think that it has been contended that they do. At the highest it can be said that they may proceed upon an erroneous assumption that the word "sold" in section 17(1)(a) of the Income Tax Act	 1945	 has a meaning which I hold it has not. This may be so and	 if so	 it is an excellent example of the proposition to which reference was made in the report of the Committee of the Privy Council in In re MacManasway(1) and again by my noble and learned friend Lord Radcliffe in Inland Revenue Commissioners vs Dowdall	 O 'Mahoney & Co. Ltd. (2) that the beliefs or assumptions of those who frame Acts of Parliament cannot make the law". For the reasons expressed above	 we hold that the judgment of the High Court dated 25th March	 1963 is right and these appeals must be dismissed with costs. One set of hearing fee. Y.P. Appeals dismissed.

The respondents flied returns for the year 1953 54 and they were provisionally assessed on 14 10 1954	 and regular assessment was. made on 27 2 58. For the next four succeeding years the respondents filed returns	 and for all the years the regular assessments under section 23 of the Income Tax Act	 1922 were made after 27 2 58. SinCe no estimate of the tax payable on their income as required by section 18A was seat nor the in advance paid	 the Income Tax Officer while assessing them under section 23 held that they were liable to pay interest under section 18A(8) and in addition he applied the provisions of section 18A(9)(b) and imposed a penalty for each year of assessment by virtue of section 28 read with section 18A(9)(b). The respondents preferred appeals to the Appellate Assistant Commissioner on the ground that the levy of interest and penalty 'was unauthorised. The appeals were dismissed	 and the respondents went :in revision	 which was also dismissed. Thereupon	 the respondents filed writ petitions in the High Court to quash the order and succeeded. The High Court held that section 18(3) of the Act did not apply to the facts of the case as there had been a provisional assessment under section 23B of the Act in 1954. In appeals to this Court	 by the Revenue the question for consideration was whether the expression "any person who has not hitherto been assessed" in section 18A(3) of the Indian Income Tax Act	 1922 after the all Income Tax Amendment Act 67 of 1949 should be interpreted so as to 'include a person who has only been provisionally assessed under section 23B 	of that Act. HELD : The appeals must be dismissed. Even when the tax is provisionally assessed	 there necessarily has to be a determination of the total income of the assessee. The only difference is that under section 23 the total income is determined after the Income Tax Officer has satisfied himself fully about the correctness of the return fled by taking steps	 if necessary	 under sections 22(4) and 23(2) of the Act. In the case of a provisional assessment under section 23B. of the Act	 the powers under sections 22(4) and 23(2) of the Act are not to be exercised and the Income Tax Officer has to determine the tax on the basis of the return filed by the assessee after taking into consideration the accounts and documents available	 if any	 and after giving effect to certain allowances and losses. In other words	 what the Income Tax Officer has to do is to assess provisionally the total income of the assessee and thereafter he has to determine the tax payable on the basis of that provisionally assessed income. [731 A D] It is important to notice that in section 18A(1) the expression "assessed" is used without any qualification or restriction as to whether the assessment should be a regular assessment or any other type of assessment 725 under the Act. It is also manifest that in section 18A sub section (5) the two expressions "provisional assessment" and "regular assessment" are expressly mentioned. The expression "regular assessment" is also repeatedly used in section 18A	 sub. section 6	 7	 8 and 9. There is therefore	 no warrant for restricting the meaning of the word "assessed" in section 18A(1) so as to include only a "regular assessment" under section 23 of the Act. There is no reason why Parliament did not add the word "regularly" in the sub section so as to qualify the word "assessed". Since there is no such qualification	 the word "assessed" in section 18A(3) should be read in its ordinary sense as including every kind of assessment including a provisional assessment under section 23B of the Act. [732 A C] There is nothing in the 1961 Act to suggest that Parliament intended to explain the meaning or clear up doubts about the meaning of the word "assessee" in section 18A(3) of the earlier Act. Generally speaking a subsequent Act of Parliament affords no useful guide to the meaning of another Act which came into existence. before the later one was ever framed. Under special circumstances	 the law does however admit of a subsequent Act to be resorted to for this purpose but the conditions under which the later Act may be resorted for the interpretation of the earlier Act are strict; both must be laws on the same subject and the part of the earlier Act which it is sought to construe must be ambiguous and capable of different meanings.
