Summarize the following court judgment. Appeal No. 751 of 1965. Appeal from the judgment and order dated December 18	 1962 of the Madras High Court in Tax Case No. 143 of 1960. A.K. Sen	 K. Parasarn	 K. Rajender Chaudhuri and K. R Chaudhuri	 for the appellant. B.Sen	 T. A. Ramachandran	 section P. Nayyar for R. N. Sachthey	 for the respondent. The Judgment of the Court was delivered by Ramaswami	 J. This appeal is brought	 by certificate	 against the judgment of the Madras High Court dated December 18	 1962 in T.C. No. 143 of 1960. The appellant (hereinafter called the 'assessee ') was a firm called O.RM.M.SP. Firm which was registered under section 26(A) of the Income tax Act	 1922 (hereinafter called the '1922 Act '). Prior to the constitution of the firm	 the partners were members of a Hindu undivided family. The family which consisted of Meyyappa Chettiar and his two brothers carried on money lending business in India and in the former Federated Malaya States and it was assessed under the Indian Income tax Act	 1918 (hereinafter called the '1918 Act '). There was a disruption of the joint family status on June 2	 1938	 and thereafter the members of the family continued the business as partners. In the course of the assessment for the year 1939 40 it was claimed by Meyyappa Chettiar	 one of the members of the family that having regard to the severance of joint family status	 the income of the family from April 13	 1938 to June 2	 1938 was not liable to be taxed by reason of the provisions of section 25(3) & (4). The Income tax Officer accepted the fact of partition amongst the members of the family	 but rejected the contention that the family was not liable to pay tax on the profits for the said period. The High Court ultimately called for a reference on the following question: "Whether the income of the family from 13th April 1938 to 2nd June 1938 is not liable to be taxed by virtue of Section 25(3) of the Indian Income tax Act" After receipt of the reference the High Court held that there was no discontinuance of the business within the meaning of section 25(3). The view taken by the High Court was that when a Hindu undivided 907 family carrying on a business	 which was taxed under the 1918 Act	 became disrupted and the members continued the business there. after as partners	 there could be no discontinuance but only succession by the firm of the business of the family. It was held in that case that it was the assesse firm which took over the business of the Hindu undivided family. The firm was dissolved on March 2	 1952. In the assessment for the year 1952 53 the assessee applied for relief under section 25(3) of the 1922 Act. The claim was rejected by the Income tax Officer on March 7	 1956. The assessee preferred an appeal to the Appellate Assistant Commissioner who dismissed the appeal holding that in the case of business carried on in foreign territory the business as such is not assessed under section 3 of the 1918 Act but only receipt of the income in British India is assessed and it cannot therefore be held that the foreign business of the appellant was charged to tax under the 1918 Act. The assessee took the matter in further appeal to the appellate Tribunal which considered that the assessee was entitled to relief under section 25 (3) of the 1922 Act except for the income received from the house properties in Malaya. The appellate Tribunal accordingly allowed the appeal of the assessee in part. Both the assessee and the Department applied to the appellate Tribunal for reference of the questions of law to the High Court. The appellate Tribunal allowed the applications and stated a case to the High Court on the following questions of law: "(i) Whether the assessee is entitled to both the parts of the relief contemplated under section 25(3) of the Act in respect of foreign business at Penang	 Ipoh and Kambar ? (ii)Whether the applicant is also entitled to relief under section 25 (3) of the Act with regard to rental income from house properties owned by the foreign firm which was discontinued in the year of assessment. " The appellate Tribunal also referred another question for the opinion of the High Court but it is not the subject matter of the present appeal. The High Court held that the assessee was not entitled to relief under section 25(3) of the 1922 Act and accordingly answered both the questions in favour of the Department. The view taken by the High Court was that the foreign business of the assessee cannot be deemed to have been charged under the provisions of the 1918 Act because the assessee was only taxed on remittances received from the profits of the foreign business and there was no tax on the foreign business itself under the 1918 Act. The High Court accordingly reached the conclusion that the assessee was not entitled to relief under section 25 (3) of the 1922 Act. 908 Section 25 (3) of the 1922 Act is to the following effect: "25. (3) Where any business	 profession or vocation on which tax was at any time charged under the provisions of the Indian Income tax Act	 1918 (VII of 1918)	 is discontinued	 then	 unless there has been a succession by virtue of which the provisions of sub section (4) have been rendered applicable no tax shall be payable in respect of the income	 profits and gains of the period between the end of the previous year and the date of such discontinuance	 and the assessee may further claim that the income	 profits and gains of the previous year shall be deemed to have been the income	 profits and gains of the said period. Where any such claim is made	 an assessment shall be made on the basis of the income	 profits and gains of the said period	 and if an amount of tax has already been paid in respect of the income	 profits and gains of the previous year exceeding the amount payable on the basis of such assessment	 a refund shall be given of the difference. " Under this section exemption from liability to pay tax in respect of the income	 profits and gains may be claimed by an assessee if the business is one in respect of which tax was charged at any time under the 1918 Act	 and the business is discontinued there being no succession by virtue of which the provisions of subsection (4) of section 25 have been rendered applicable. Section 25(3) however	 applies even if the person assessed under the 1918 Act was different from the person who claims relief under that section provided the former was the predecessor in interest of such person in relation to the business. The reason for enacting section 25(3) was that under the 1918 Act	 income tax was levied by virtue of section 14(2) of the 1918. Act	 on the income of the year of assessment. Tax was	 therefore	 levied in the financial year 1921 22 on the income of that year. By the 1922 Act the basis of taxation was altered and by section 3 of that Act	 charge for tax was imposed upon the income of the previous year. When the 1922 Act was brought into force on April 1	 1922	 two assessments in respect of the same income for the year 1921 22 had to be made. The income for 1921 22 was accordingly charged to tax twice; it was charged under the 1918 Act and it was also charged to tax under section 3 of the 1922 Act read with the appropriate Finance Act	 resulting in double taxation in respect of the income for that year. But with a view to make the number of assessments equal	 to the number of years during which the business was carried on	 the legislature enacted the exemption prescribed by section 25(3). This benefit was however restricted only to the income	 profits and gains of business	 profession or vocation on which tax had been charged under the provisions of the 1918 Act. By enacting section 25(3) the legislature intended to exempt the income	 profits and 909 gains resulting from the activity styled business	 profession or vocation from tax when the business	 profession or vocation is discontinued if tax was charged in respect thereof under the 1918 Act. The first question to be considered in this appeal is whether the assessee is entitled to both parts of relief contemplated under section 25(3) of the 1922 Act in respect of the foreign business at Penang	 lpoh and Kambar. The controversy between the parties turns on the question whether the foreign business of the assessee was at any time charged under the provisions of the 1918 Act. It has been found by the appellate Tribunal that the assessee was taxed on remittances received from and out of the profits of the foreign business. The finding of the Appellate Assistant Commissioner is stated in these terms: "The entire profits of the foreign business came to be assessed in the hands of the appellant under the 1918 Act	 not because it was a business income but because such income had been remitted into British India. Therefore	 in fact also it is not the foreign profits of a business that has been charged to tax but only the remittance which in the particular case was not less than the profits of the year. " We have therefore to proceed on the footing that the assessee received the entire profits of the foreign business in British India and the entire profits were assessed to income tax in the hands of the assessee under the 1918 Act. It is necessary	 at this stage	 to set out the relevant provisions of the 1918 Act. Section 3	 the charging section stated as follows: "3. (1) Save as hereinafter provided	 this Act shall apply to all income from whatever source it is derived	 if it accrues or arises or is received in British India	 or is	 under the provisions of this Act	 deemed to accrue or arise or to be received in British India. Section 5 mentioned the classes of income chargeable to income tax and reads as follows: "5. Save as otherwise provided by this Act	 the following classes of income shall be chargeable to income tax in the manner hereinafter appearing	 namely (i) Salaries. (ii) Interest on securities. (iii)Income derived from house property. (iv) Income derived from business. 910 (v) Professional earnings. (vi) Income derived from other sources. " Section 9 of the 1918 Act enumerated the permissible deductions in the computation of the profits of the business. The question for determination is whether the foreign business of the assessee was at any time charged under the provisions of section 3 of the 1918 Act. It has been found in this case that the entire income of the foreign business was remitted to the assessee and tax imposed on that income under the 1918 Act. We are of the opinion that in the context of these facts the foreign business of the assessee must be held to be charged under the provisions of the 1918 Act within the meaning of section 25(3) of the 1922 Act. It is manifest that by section 3 of the 1918 Act the charge was made on the receipt of income in British India and as the income received by the assessee was derived from the foreign business and was in relation to the foreign business it must be taken that there was an assessment to tax on the foreign business within the meaning of section 25(3) of the 1922 Act. In other words	 the tax under the 1918 Act was charged upon the assessee in respect of his activity styled 	foreign business ' and in relation to it and it must hence be taken	 upon the facts found by the appellate Tribunal in this case	 that the foreign business of the assessee was charged under the 1918 Act within the meaning of section 25(3) of the 1922 Act. The High Court has taken the view that the foreign business of the assessee was not charged under the 1918 Act because what was taxed was the remittances received by the assessee from the foreign business and not the foreign business itself. In taking this view	 the High Court has followed its previous decision in Commissioner of Income tax	 Madras vs section V.R.M. Palaniappa Chettiar and Others(1) in which it was held that the words "on which" in section 25(4) of the 1922 Act cannot be interpreted as meaning "with reference to which" and that in order to claim and avail the benefit under section 25(4) the tax clearly should be charged on the business as such under the 1918 Act. At page 173 of the Report Satyanarayana Rao	 J. stated as follows: "The relief under sub clause (4) is permissible only if the tax on the business was charged under the provisions of the Indian Income tax Act	 1918. If the foreign business at Muor was not and could not have been charged under the Act and the share in the profits of the family from that foreign business was charged under section 3 only on the receipt in British India	 can it be said that the charge so made was a charge of a tax on the foreign business. The income received by the joint family could not have been charged under the head 'income derived from business ' but only as a receipt under section 3. The argument	 however	 on behalf 1 911 of the assessee by his learned Advocate Mr. Rajah Iyer was that the words "on which tax was at any time charged" should be construed as meaning "with reference to which tax was at any time charged. " In other words	 the conten tion is that the income derived by the assessee was in relation to a business and therefore the assessment of the income must be treated as an assessment of the business. No doubt	 under the provisions of the Income tax Act	 the tax is payable by an assessee but the assessment of the tax is on the basis of various heads of income derived by the assessee one of which is business. It cannot	 therefore	 be said that because tax was payable by the assessee on the profits rec eived from a business in a foreign territory such assessment is an assessment of the business. " In our opinion	 the view adopted by the High Court in Commissioner of Income tax	 Madras vs section V.R.M. Palaniappa Chettiar and Others( ) must be taken to be impliedly over ruled by the recent decision of this Court in Commissioner of Income tax. Bombay City 1 vs Chugandas & Co.(2) in which the question was whether the interest on securities formed part of the assessee 's business income for the purpose of the exemption from tax under section 25(3) of the 1922 Act. It was held by this Court that the assessee was entitled to exemption under section 25(3) in respect of interest on securities as well	 and there was no reason to restrict the condition of the applicability of the exemption under section 25(3) only to income on which the tax was payable under the head "Profits and gains of business	 profession or vocation". It was further observed in that case that tax is charged under the Income tax Acts on specific units	 such as	 individuals	 Hindu undivided families	 companies	 local authorities	 firms and associations of persons etc. and business	 profession or vocation is not a unit of assessment. When	 therefore	 section 25(3) enacts that tax was charged at any time on any business	 it is intended that the tax was at any time charged on the owner of any business. If that condition be fulfilled in respect of the income of the business under the 1918 Act	 the owner or his successor in interest in relation to the business	 will be entitled to get the benefit of the exemption under it if the business is discontinued. We are accordingly of the opinion that the High Court was in error in holding that the foreign business of the assessee was not charged under the provisions of the 1918 Act. The first question must therefore be answered in favour of the assessee and it must be held that the assessee is entitled to both parts of relief contemplated under section 25(3) of the 1922 Act in respect of the foreign business at Penang	 lpoh and Kambar. (1) (2) 912 The second question of law arising in this appeal is whether the assessee was entitled to relief under section 25(3) of the 1922 Act with regard to the rental income from house properties owned by the foreign firm which was discontinued in the year of account. A similar question was the subject matter of consideration in Commissioner of Income tax	 Bombay City 	 vs Chugandas and Company(1) which has already been referred to. In that case	 the assessee firm	 a dealer in securities holding securities as its stock in trade	 had been charged to tax under the 1918 Act	 in respect of business. It received Rs. 4	13	992 and Rs. 1	01	229 as interest on securities in the years 1946 and 1947 respectively. The firm discontinued its business on June 30	 1947. The question at issue was whether the interest on securities formed part of the assessee 's business income for the purpose of the exemption from tax under section 25(3) of the 1922 Act. It was held by this Court that the assessee was entitled to exemption under section 25(3) in respect of interest on securities as well. It was pointed out that there was no reason to restrict the condition of the applicability of the exemption under section 25(3) only to income on which the tax was payable under the head "Profits and gains of business	 profession or volcation". The exemption under section 25(3) is general. It was explained by this Court that the heads of income described in section 6 of the 1922 Act	 and further elaborated for the purposes of computation in sections 7 to IO and 12	 12A	 12AA and 12B	 are intended merely to indicate the classes of income. The heads do not exhaustively delimit sources from which income arises. Business income is broken up under different heads only for the purpose of computation of the total income. By that breaking up the income does not cease to be the income of the business	 the different heads of income being only the classification prescribed by the Incometax Act for computation. The ratio of this decision applies to the present case and it must accordingly be held that the assessee is entitled to relief under section 25(3) of the 1922 Act with regard to the rental income from the house properties owned by the foreign firm which was discontinued in the year of account. For these reasons the judgment of the Madras High Court is set aside and this appeal must be allowed with costs. R.K.P.S. (1) ; Appeal allowed.

Prior to the constitution of the assessee firm	 its partners were members of a Hindu undivided family which carried on money lending business in India and in Malaya and which was assessed to tax under the Income Tax Act	 1918. There was a partition in the family on June 2	 1938	 and thereafter its members continued the business as partners in the assessee firm. The firm was dissolved on March 2	 1952. In the assessment for the year 1952 53	 the assessee applied for relief under section 25(3) of the Income Tax Act.	 1922. This claim was rejected by the Income Tax Officer and an appeal to the Appellate Assistant Commissioner was dismissed on the view that in the case of business carried on in foreign territory	 the business as such was not assessed under section 3 of the 1918 Act and only income received in India was so assessed; consequently	 no relief could be claimed under section 25(3) of the 1922 Act. A further appeal to the Appellate Tribunal was partly allowed as the Tribunal considered that the assessee was entitled to relief under section 25(3) except in respect of the income received by the assessee firm from certain house properties in Malaya. The High Court	 upon a reference	 disagreed with the Tribunal and held in favour of the department. On appeal to this Court	 HELD : (1) The High Court was in error in holding that the foreign business of the assessee was not charged under the provisions of the 1918 Act. The assessee was therefore entitled to relief under section 25(3). When section 25(3) refers to tax charged on any business	 it is intended to refer to tax charged on the owner of any business. If tax is shown to have been charged in respect of the income of the business under the 1918 Act	 the owner or successor in interest in relation 'to the business will be entitled to get the benefit of the exemption under section 25(3) if the business is discontinued. In the context of the finding by the lower courts that the entire income of the foreign business was remitted to the assessee and tax imposed on that income under the 1918 Act	 the foreign business of the assessee must be held to have been charged under the provisions of the 1918 Act within the meaning of section 25(3) of the 1922 Act. [911 F H] (ii)The assessee was also entitled to relief under section 25(3) on the rental income from the house properties owned by the foreign firm which was discontinued in the year of account.

By that breaking up the income does not cease to be the income of the business. [912 E F] Commissioner of Income tax	 Madras vs S.V.R.M.
