Summarize the following court judgment. Civil Appeal No. 842 of 1964. Appeal by special leave from the judgment and order dated February 19	 1963 of the Kerala High Court in Income tax Referred Case No. 23 of 1962. R. Ganapathy Iyer and B.R.G.K. Achar and R. N. Sachthey	 for the appellant. 675 A. V. Viswanatha Sastri and R. Gopalakrishnan	 for the respondent. The Judgment of the Court was delivered by Subba Rao	 J. The respondent	 the South India Bank Limited	 Trichur	 is a banking company. This appeal is concerned with the assessment year 1956 57	 corresponding previous year being the calendar year 1955. During the accounting year the Bank received a sum of Rs. 44	720/ towards interest in respect of taxfree Cochin and Travancore Securities. During the course of the assessment of its income to tax	 it claimed that rebate should be allowed on the entire sum of Rs. 44	720/ received as interest from the said securities. But	 the Income tax Officer	 while completing the assessment	 arrived at the figure of Rs. 33	444/ as the sum representing two items	 viz.	 (i) reasonable sum expended by the assessee in realizing the said interest; and (ii) the interest payable on the money borrowed for the purpose of investment. After deducting the said sum from the interest receivable from the said securities	 he granted only a sum of Rs. 7	276/ as rebate for income tax. On appeal	 the Appellate Assistant Commissioner upheld the view of the Income tax Officer. On a further appeal	 the Income tax Appellate Tribunal	 Madras Bench	 held that the Bank was entitled to a	 rebate on the gross amount of interest amounting to Rs. 44	720/ . At the instance of the Department	 the Tribunal referred the following question to the High Court of Kerala for its decision : "Whether	 on the facts and circumstances of the case	 the Tribunal was right in holding that Explanation to section 8 is not applicable in this case and that the entire interest of Rs. 44	720/ earned by the assessee from securities issued by the former Native States	 etc. is entitled to rebate of income tax." A Division Bench of the High Court expressed the opinion that the entire interest of Rs. 44	720/ was entitled to rebate for income tax under the notification issued by the Central Government in exercise of its powers under section 60 A of the Indian Income tax Act	 1922. Hence the appeal. Mr. R. Ganapathy Iyer	 learned counsel for the Revenue	 argued that under section 8 of the Indian Income tax Act	 income tax was computed under the head "interest on securities" in respect of the interest received by an assessee on any government securities minus the expenditure incurred by him to realise the same in 676 terms of the first proviso and the Explanation thereto	 that when under the third proviso the assessee was exempted from paying tax on the interest receivable on any securities of State Government issued income tax free	 he was only exempted from such tax payable by him if it was not so exempted. To put it differently	 his argument was that the exemption under the third proviso was only in regard to that part of the interest which was taxable but for the exemption. His further contention was that the notification issued by the Central Government under section 60A of the Income tax Act did not enlarge the scope of the exemption but that the said notification must be construed only in terms of section 8 of the Income tax Act. Mr. A. V. Viswanatha Sastri	 learned counsel for the respondent	 argued that the substantive part of section 8	 read with the first proviso and the Explanation thereto	 had no application to securities issued income tax free and that the interest from the State Government securities was governed by the third proviso which did not provide for any deduction from the interest receivable from such securities for the purpose of income tax. Further he sought to sustain the order of the High Court on the ground that the interest in question was solely governed by the notification issued by the Central Government whereunder the entire interest receivable from such securities was exempted from income tax. As we agree with the High Court on the construction of the notification issued by the Central Government	 we do not propose to express our opinion on the rival contentions of the parties based upon the provisions of section 8 of the Income tax Act. Section 8 of the Income tax Act provides for the computation of income and deductions therefrom under the head "interest on securities". Section 60 of the Act confers a power on the Central Government to make an exemption	 reduction in rate	 or other modifications in respect of income tax in favour of any class of income or in regard to the whole or any part of any income of any class of persons. This power is conferred on the Government to meet special situations de hors section 8. If section 8 of the Income tax Act makes an exemption in respect of a particular income	 there is no scope or occasion for invoking the special power conferred on the Central Government under section 60A of the Income tax Act. Unless we accept the contention that the notification under section 60A was issued by the Central Government in superabundant caution to cover the same ground occupied by section 8 we need not attribute any such redundancy to the Central Government we do not see any reason why the notification should not be construed on its own 677 terms in its application to the question of rebate raised in this	 case. The said notification reads : "No income tax shall be payable by an assessee on the interest receivable on the following income tax free loans issued by the former Government of Travancore or by the former Government of Cochin	 provided that such interest is received within the territories of the State of Travancore Cochin and is not brought into any other part of the taxable territories to which the said Act applies. Such interest shall	 however	 be included in the total income of the assessee for the purposes of Section 16 of the Indian Income tax Act	 1922 It is common case that this notification applies to the securities in question. It will be noticed that this notification does not refer to the provisions of section 8 of the Income tax Act at all. It gives a total exemption from income tax to an assessee in respect of the interest receivable on Income tax ' free loans mentioned therein. It gives that exemption subject to two conditions	 namely	 (i) that the interest is received within the territories of the State of Tranvancore Cochin	 and (ii) that it is not brought into any other part of the taxable territories. It includes the said exempted interest in the total income of the assessee for the purpose of section 16 of the Income tax Act. Shortly stated	 the notification is a self contained one; it provides an exemption from income tax payable by an assessee on a particular class of income subject to specified conditions. Therefore	 there is no scope for controlling the provisions of the notification with reference to section 8 of the Income tax Act. The expression "interest receivable on income tax free loans" ' is clear and unambiguous. Though the point of time from which the exemption works is when it is received within the territories of the State of Travancore Cochin	 what is exempted is the interest receivable. "Interest receivable" can only mean the amount of interest calculated as per the terms of the securities. It cannot Jr obviously mean interest receivable minus the amount spent in receiving the same. We	 therefore	 hold	 agreeing with the High Court	 that no income tax is payable in respect of the entire interest of Rs. 44	720/ earned by the assessee from securities issued by the former native States. In the result	 the appeal fails and is dismissed with costs.

The respondent was a banking company. During the accounting year for the assessment year 1956 57 the Bank received a certain sum towards interest in respect of tax free securities	 and claimed rebate for the whole amount under the notification issued by the Central Government in exercise of its power under section 60 A of the Indian Income tax Act	 1922. The Income tax Officer however	 while completing the assessment allowed rebate only on the amount of interest that remained after deduction of sums expended by the assessee in realising the said interest and the interest payable on the money borrowed for the purpose of investment. The Appellate Assistant Commissioner upheld the order of the Income tax Officer but the Tribunal held that the respondent was entitled to rebate on the gross amount of interest. In reference	 a Division Bench of the High Court upheld the Tribunal 's view; the Commissioner of Income tax appealed to this Court. It was contended for the Revenue that the exemption under the third proviso to section 8 was only in regard to that part of the interest which was taxable but for the exemption. The further contention was that the notification issued by the Central Government under section 60 A of the Income tax Act did not enlarge the scope of the exemption but that the said notification must be construed only in terms of section 8 of the Income tax Act. HELD : The notification had to be construed on its own terms in its application to the question of rebate raised in the present case. It is not intended to cover the same ground occupied by section 8	 and there is no scope for controlling the provisions of the notification with reference to section 8. The expression 'interest receivable on income tax free loans ' in the notification is clear and unambiguous	 and can only mean the amount of interest calculated as per the terms of the securities. It cannot obviously mean interest receivable minus the amount spent in receiving the same. No income tax was therefore payable in respect of the interest by the assessee from the securities in question. [677 E G]
