Summarize the following court judgment. Appeal No. 2053 of 1971. Appeal by special leave from the Judgment & Order dated the 8th July	 1971 of the Bombay High Court in S.C.A. No. 1346/68. M. C. Bhandare	 P. H. Parekh and section Bhandare	 for the appellant. The Judgment of the Court was delivered by SARKARIA	 J. Whether the difference of 10 per cent between an Industrial Company and other Companies in the levy of Income tax provided in the Finance Act	 1966 is to be construed a "rebate" or "relief" in the payment of any direct tax	 for the development of an industry for the purposes of section 7(e) of the 	 (for short	 the Bonus Act) is the short question that falls to be answered in this appeal by special leave. The appellant is a Private Ltd. Company. it manufactures automobile ancillaries and other goods in its Factory at Bombay. It employs about 170 workmen. The workmen demanded bonus for the year 1964 65. Their demand was not met by the Company. Conciliation proceedings before the Conciliation Officer having failed	 the dispute was submitted to the Government which by its Order	 dated May 2	 1967 referred the same for adjudication to the Industrial Tribunal. One of the points mooted before the Tribunal was	 whether in calculating the available surplus	 the direct tax payable by the Company was deductible at the rate of 55 per cent or 65 per cent. The case of the Mazdoor Saneh (Respondent No. 1) was that the rate should be 55 per cent as the Company was paying the tax at the rate As against this	 the Company contended that it was entitled to deduct as per section 7(e) of the Bonus Act	 direct tax at the normal rate of 65 per cent and not at 55 per cent which was only a confessional levy amounting to a "relief" for the purpose of development. The Tribunal accepted the contention of the Company. After referring to the speech of the Finance Minister on the Budget of 196667	 the Tribunal held: assessed to income tax at the rate of 65 per cent	 those engaged in industrial undertakings have been assessed at the concessional rate of 55 per cent	 as a measure of rendering assistance to their growth. Such a concession would	 unquestionably amount to relief for the purpose of development as contemplated by Section 7(e) of the Act. " Aggrieved	 the Mazdoor Sangh impugned the Tribunal 's Award	 dated 29 2 1968	 by a Writ Petition under Article 227 of the Con 544 stitution before the High Court of Bombay. The High Court held that the Company being an Industrial Company	 was liable to pay tax under the Finance Act	 1966 at the rate of 55% only on its total income after deducting depreciation. Therefore it could not claim deduction at a rate higher than 55% in calculating the available surplus. In the result	 the High Court set aside the Award and remitted the case to the Tribunal for further disposal in accordance with law. Hence this appeal by the Company. Broadly	 the scheme of the Bonus Act is this : At first	 the gross profits derived by an employer from an establishment are calculated in the manner specified in the First Schedule	 or the Second Schedule	 whichever may be applicable (section 4). On the basis of such gross profits	 the available surplus for the particular accounting year is computed. This is done by deducting therefrom the sums referred to in Section 6. According to Clause (c) of Section 6	 one of the sums so deductible is: "Subject to the provisions of Section 7	 any direct tax which the employer is liable to pay for the accounting year in respect of his income	 profits and gains during that year". Section 7	 to which section 6(c) is subject	 provides how for the purposes of the Act	 the direct tax payable by the employer is to be calculated. Clause (e) of Section 7 is material. It runs thus : "no account shall be taken of any rebate (other than development rebate or development allowance) or credit or relief or deduction (not hereinbefore mentioned in section) in the payment of any direct tax allowed under any law for the time being in force relating to direct taxes or under the relevant annual Finance Act	 for the development of any industry". The rates of income tax applicable to Private Ltd. Companies tinder Paragraph F	 Part I of the First Schedule fixed by the Finance Act	 1966	 are as follows : 1. In the case of a domestic Company(A) (1). (2) where the Company is not a company in which the public are substantially interested. (i) in the case of an industrial Company (1) on so much of the total income as does not exceed Rs. 10	00	000 55 per cent. (2) on the balance	 if any of the total income 60 per cent. (ii) in any other case 65 per cent of the total income". It is not disputed that the Company being an industrial Company with total income for the relevant year	 not exceeding Rs. 10	00	900		 545 the rate of tax under the above Paragaph 1(A) (2) (i)	 applicable to it was 55 per cent and not 65 per cent of the total income. However	 Mr. Bhandare 's contention is that this was only a concessional rate and not the normal rate which was prescribed under Clause (ii) of the above Paragraph 1(A) (2). The point pressed into argument is that this ten per cent concession in the tax rate was given to Industrial Companies with a view to promote development of Industry and	 as such	 must be deemed to be a "relief" or "rebate" in the payment of direct tax of the kind contemplated by Section 7(e) of the Act. Reliance for this contention has been placed on the speech of the Finance Minister on the Budget of 1966 67	 wherein he proposed to provide "certain reliefs" which he considered "necessary for providing a suitable climate of growth"	 and	 in that context	 described the rate of 55% tax on Industrial Companies as a "concessional rate". We are afraid what the Finance Minister said in his speech cannot be imported into this case and used for the construction of Clause (e) of Section 7. The language of that provision is manifestly clear and unequivocal. It has to be construed as it stands	 according to its plain grammatical sense without addition or deletion of any words. As a general principle of interpretation	 where the words of a statute are plain	 precise and unambiguous	 the intention of the Legislature is to be gathered from the language of the statute itself and no external evidence such as Parliamentary Debates	 Reports of the Committees of the Legislature or even the statement made by the Minister on the introduction of a measure or by the framers of the Act is admissible to construe those words. It is only where a statute is not exhaustive or where its language is ambiguous	 uncertain	 clouded or susceptible of more than one meaning or shades of meaning	 that external evidence as to the evils	 if any	 which the statute was intended to remedy	 or of the circumstances which led to the passing of the statute may be looked into for the purpose of ascertain ing the object which the Legislature had in view in using the words in question. In the case before us	 the language of Section 7(e) is crystal clear and self contained. It indicates in unmistakable terms that the 'rebate or relief ' in the payment of any direct tax in order to fall within the purview of this clause must satisfy two conditions	 viz.	 (i) that it must be a rebate or relief "allowed under any law for the time being in force relating to direct taxes or under the relevant annual Finance Act"	 and further	 (ii) that it must be a relief or rebate for the development of any Industry. In the present case	 condition (i) is lack ing. The Finance Act	 1966	 does not say that this difference of 10per cent in the rates of tax applicable to an Industrial Company and any other Company is to be deemed to be a rebate or relief for the development of Industry. Nor has it been shown that this difference in the rates is allowed as a rebate or relief under any other extant law relating to direct taxes. 546 The High Court was	 therefore	 right in holding that it was not 	permissible to use the speech of the Finance Minister to construe the clear language of the statute	. For the forgoing reasons the question posed above is answered in the negative and the appeal is dismissed. As regards the costs	 the delay in payment of the bonus caused by the pendency of this appeal has been amply compensated vide this Court 's order dated February 17	 1972	 which is to this effect "The order of ex parte stay is made absolute on the condition that the petitioner appellant shall pay six percent interest on any amount that is found payable by the appellant to the respondent workmen from the date the award become enforceable till the disposal of the appeal in this Court	 in case the appeal fails in this Court. " The appeal has been heard ex parte	 we therefore make no order as to costs. P.B.R. Appeal dismissed.

Section 7 of the Bonus Act provides as to how the direct tax payable by an employer is to be calculated for the purpose of computing the available surplus. Clause (e) of section 7 enacts that no account shall be taken of any 'rebate ' or 'relief ' or deduction in the payment of any direct tax allowed under any law for the time being in force relating to direct taxes or under the relevant annual Finance Act for the development of any industry. in the case of an industrial company	 which is not a company in which public 	arc substantially interested	 the Finance Act. 1966 fixed the rate of income tax at 55% on so much of the total income as did not exceed Rs. ten lakhs	 on the balance	 if any	 of the total income 60% and 65% in the case of any other 	company. In a dispute between its employees and the appellant	 which is an industrial company the latter contended that for the purpose of computing the available surplus it was entitled to deduct direct tax at 65% and not 55% which was only a confessional levy amounting to a 'relief ' for the purpose of development. The Tribunal accepted the contention of the appellant. The High Court allowed the respondent 's writ petition under article 227 of the Constitution holding that the company being an industrial company could not claim deduction at a rate higher than 55% in calculating the available surplus. On appeal it was contended that the 10% concession in the rate was given to industrial companies with a view to promote development of industry and as such must be deemed to be a 'relief ' or 'rebate ' in be payment of direct tax contemplated by section 7(e) of the Bonus Act. Reliance for this had been placed on the speech of the Finance Minister on the budget for the year 1966 67. Dismissing the appeal	 HELD : (1) The company being an industrial company with total income not exceeding rupees ten lakhs the rate of tax under paragraph 1(A)(2)(i) of the Finance Act. 1966 applicable to it was 55% and not 65% of the total income. [544H 545A] (2) The 'rebate or relief ' in the payment of any direct tax	 in order to fall within the purview of section 7(e) of Bonus Act. must be a rebate or relief "allowed under any law for the time being in force relating. to direct taxes or under the relevant Finance Act. for the development of any industry" which is one of the conditions to be satisfied. In the present case it did not satisfy this condition. The Finance Act	 1966 did not say that this difference of 10% in the rate of tax applicable to an industrial company and any other company is to be deemed to be a rebate or relief for the development of industry. No	 has it been shown that this difference in the rates is allowed as a rebate or relief under any other extant law relating to direct taxes. [545F H] 3 (a) It was not permissible to use the speech of the Finance Minister to construe the clear language of the statute. [545C D] (b) As a general principle of interpretation	 where the words of a statute are 	plain	 precise and unambiguous the intention of the Legislature has to be gathered from the language of the statute itself and no external evidence such as Parliamentary debate 	 Reports of the Committees of the Legislature or even the statement made by the Minister on the introduction of a measure or by the framers of the Act is admissible to construe those words. It is only where a statute is not exhaustive or where its language is ambiguous	 uncertain	 clouded or susceptible of more 543 than one meaning or shades of meaning that external evidence as to the evils. if any. which the statute was intended to remedy. or of the circumstances which led to the passing of the statute may be looked into for the purpose of ascertain ing the object which the Legislature had in view in using the words in question.
