Summarize the following court judgment. Appeals Nos. 15 and 16 of 1969. Appeals from the judgment and order dated December 3	 1968 of the Gujarat High Court in Letters Patent Appeals Nos. 43 and 42 of 1966 respectively. M. C. Chagla	 P. C. Bhartari	 P. N. Tiwari and J. B. Dada chanji	 for the appellants (in both the appeals). I. N. Shroff	 for the respondent (in both the appeals). The Judgment of the Court was delivered by Hegde	 J. Common questions of law arise for decision in these appeals	 by certificate. The suits from which these appeals arise have been considered together and decided by common judgments	 838 both in the High	 Court as well as in the courts below. It is convenient to do so in this Court as well. The suits in questions are representative suits. The plaintiffs appellants who are consumers of electricity in the Godhra area sued the respondent company on behalf of all the consumers in that area seeking to restrain the respondent from enforcing the enhanced charges sought to be collected from the consumers of power used for lights and fans as well as of motive power. The facts leading to these appeals may no	%	 be stated. On November 19	 1922	 the then Government of Bombay granted a licence under the to a concern called Lady Sulochna Chinubhai & Co. authorising it to generate and supply electricity to the consumers in Godhra area. Clause 10 of the licence prescribed the maximum charges that the licensee could levy for the power supplied. The respondent is the successor of the said licensee. After the (to be hereinafter referred to as the Supply Act) came into force	 a rating committee was constituted under section 57(2) of the Supply Act at the request of the respondent on January 19	 1950. On the recommendation of that committee	 the Government fixed with effect from February 1	 1952	 the following charges for the power supplied: (i) 0 7 9 pies per unit for the electricity supplied for lights and fans with a minimum of Rs. 3/ per month per installation and (ii) for motive power at 4 annas per unit with a minimum of Rs. 4 8 0 per month per installation. The Supply Act was amended in 1956. The respondent increas the charges for motive power from January 1	 1963 to 35 NP. per unit with a minimum of Rs. 7/ per month for every installation. On June 22. 	 1963	 the rates for light and fans were increased with effect from July 1	 1963 to 70 NP. per unit with a minimum of Rs. 51 per month for every installation. The contention of the appellants is that the respondent wag not competent to enhance the charges	 in question without the matter having been considered by a rating committee. Their suits to restrain the respondent from levying the proposed increased charges were decreased by the trial court. Those decrees were affirmed by the first appellate court as well as by a single judge of the Gujarat High Court in second appeals but the appellate bench of the Gujarat High Court reversed those decrees and dismissed the suits holding that under the Supply Act as amended in 1956 the respondent has a unilateral right to enhance the charges subject to the conditions prescribed in the VI Schedule to that Act. It is 839 as against those decisions these appeals have been brought. Civil Appeal No. 15 of 1969 relates to the enhancement of charges for electricity power for lights and fans and Civil Appeal No. 16 of 1969 relates to the enhancement of charges for the motive power. The only question that arises for decision in these appeals is whether under the provisions of the Supply Act as amended in 1956	 the respondent was competent to unilaterally enhance the charges. In these appeals we are not concerned with the provisions of the Electricity Act	 1916. There is no dispute as regards the charges fixed by the Government with effect from February 1	 1952	 under section 57(2)(c) of the Supply Act on the basis of the recommendation made by the rating committee. The appellants admit their liability to pay enhanced charges that may be fixed by ' the Government on the basis of any recommendation by a freshly	 appointed rating committee. They merely challenge the respondent 's right to unilaterally enhance the charges. According to the appellants they have a vested right to be governed by the charges fixed in 1952 until the same is revised by the Government on the basis of the recommendation of a rating committee. It was urged on their behalf that the amendments made in 1956 ' do not affect the charges fixed in 1952 and they continue to rule till altered by the Government in accordance with law. The respondent repudiates those contentions. It denies that the appellants have any vested right in the charges fixed. It was urged on its behalf that the amendments made to the Supply Act in 1956 have substantially altered the scheme as regards levying charges; it is now open to a licensee to alter the charges fixed by the Government unilaterally subject to the conditions prescribed in section 57(A) and in Sch. VI of the Supply Act. We may mention at this stage that even according to the appellants the charges that may be fixed by the Government now on the basis of the recom mendation of a rating committee can be unilaterally altered by the licensee after the period fixed in the Government order in accordance with cl. (e) of section 57(A)(1)	 expires. In order to decide the point in controversy	 we have to take into consideration the relevant provisions of the Supply Act as it stands now and as it stood prior to its amendment in 1956. For the sake of convenience we shall set out side by side the relevant provisions. The Supply Act as it stood before The Supply Act 1956 as amended In 1956 section 57. Licensee 's charges to consu section 57.

(1) If the clear profit of a licensee in any year of account is in excess of the amount of reasonable return one third of such excess. not exceeding 7 1/2 per cent of the amount of reasonable return shall be at the disposal of the undertaking. Of the balance of the excess	 one half shall be appropriated to a reserve which shall be called the Tariffs and Dividends Control Reserve and the remaining half	 shall either be distributed in the form of a proportionable rebate on the amounts collected from the sale of electricity and meter rentals 'or carried forward in the accounts of the licensee for distribution	 to the consumers in future	 in (2nd column of the page no 842) expiry of the notice referred to in 'the first proviso to that clause (ii) where such committee is to be constituted at the request of the licensee	 be constituted within three months of the date of such request; (c) a rating committee shall	 after giving the licensee a reasonable opportunity of being heard and after taking into consideration the efficiency of operation and management and the potentialities of his undertaking	 report to the State Government within three months from the date of its constitution	 making recommendations with reasons there for	 regarding the charges for electricity which the licensee may make to any class or classes of consumers so	 however. that the recommendations are not likely to prevent the licensee from earning clear profit		 sufficient when taken with the sums available in the Tariffs and Dividends Control Reserve to afford him a reasonable return as defined in the Sixth Schedule during his next succeeding three years of account: Provided that the State Government may	 if it go deems necessary	 extend the said period of three months by a further period not exceeding three month within which the report of the rating committee may be submitted to it; (d) within one month after the receipt of the report under clause (c)	 the State Government shall cause the report to be published in. the Official Gazette	 and may at the same time make an order In accordance therewith fixing the licensee 's charges for 843 such manner as the Provincial Government may direct.

THE SIXTH SCHEDULE 1. Notwithstanding anything contained in the except sub section (2) of section 9 of 1910	 22A	 and the provisions in the licence of a licensee. the licensee shall so adjust his (charges) for the sale of electricity whether by enhancing or reducing them that his clear profit in any year of account shall not	 as far as possible	 exceed the amount of reasonable return Provided that such (charges) shalt not be enhanced more than once in any year of account : Provided further that the licensee shall not be deemed to have failed so to adjust his (charges) if the clear profit in any year of account has not exceeded the amount of reasonable return by (twenty) per centum of the amount of reasonable return: Provided further that the licensee shall not enhance the (charges) for the supply of	electricity until after the expiry of a notice in writing of	 not less than sixty 844 (2nd column of the page no 844) clear days of his intention to so enhance the (charges) given by him to the State Government and and to the Board Provided further that if the (charges) of supply fixed in pursuance of the recommendations of a rating committee con stituted under sec. 57A are lower than those notified by the licensee under and in accordance with the preceding Proviso '	 the licensee shall refund to the consumers the excess amount recovered by him from them : Provided also that nothing in this Schedule shall be deemed to prevent a licensee from levying. with the previous approval of State Govt. minimum charges for supply of electricity for any purpose. The notice referred to in the third proviso to paragraph I shall be accompanied by such financial and technical data in supPort of the proposed enhancement of charges as the State Government may	 by general or special order	 specify. (1) If the clear profit of a licensee in any year of account is in excess of the amount of reasonable return	 one third of such excess	 not exceeding (five per cent) of the amount of reasonable return	 shall be at the disposal of the undertaking. Of the balance of the excess	 one half shall be appropriated to a reserve which shall be called the Tariffs and Dividends Control Reserve and the remaining half shall either be distributed in the form of a Proportional rebate on the amounts collected from the sale of electricity and meter rentals or carried	 forward in the accounts of the licensee for distribution to the consumers in future	 in such manner as the State Government may direct. (2) The Tariffs and Dividends Control Reserve shall be available for disposal by the licensee only to the extent by which the clear 845 (2nd column of the page no 845) profit is less than the reasonable return in any yea of account. (3) On the purchase of the undertaking under the terms of its licence any balance remaining in the Tariffs and Dividends Control Reserve shall be handed over to the purchaser and maintained as such Tariffs and Dividends Control Reserve: Provided that where the Undertaking is purchased by the Board or the State Government the amount of the Reserve may be deducted from the price payable to the licensee. From an examination of these provisions it would be seen that under the Supply Act prior to its amendment in 1956	 the charges fixed by the Govt. under s ' 57(2)(c) remained in force unless reduced by the licensee in the meantime till the same were altered by a subsequent order made by the Govt. after getting a fresh recommendation from the rating committee but under the law as it now stands the rate fixed by the Government under section 57 (A)(1)(d) would be in operation only for such period not exceeding three years as the State Govt. may specify in the order. Thereafter it can be enhanced by the licensee in accordance with the provisions contained in Sch. It was urged on behalf of the appellants that the present section 57 (A (1) (e) can only govern the charges fixed under section 57(A)(1)(d) and it has not impact on an order made under the old section 57(2)(c). According to the appellants the charges so fixed can only be modified by the Government after getting a report from the rating committee. Mr. Chagla	 learned Course for the appellants contended that the	 consumers who 'get power from the respondent have a vested right in the charges fixed in 1952 and that vested right cannot be considered to have been taken away by the provisions of the Amending Act. He argued that the provisions of the Amending Act are not retro spective in character nor is there any inconsistency between those provisions and the present provisions as the two operate on different fields; hence in view of section 6 of the 	 we must hold that the charges fixed by the Government in 1952 continue to be in operation. In this connection he relied on certain observations made by this Court in State of Punjab vs Mohar Singh(") and Deep Chand vs State of U.P. & Ors. On the other hand it was contended by the learned Counsel for the respondent that the rights and liabilities of the.respondents at present are exclusively regulated by the provisions of the Supply (1) ; (2) [1959] 2 Supp. section C.R. 8. 846 Act as it stands now; the terms of licences as they originally stood or as they stood on the coming into force of the Supply Act in 1948 are of no consequence now; they cannot be looked into for finding out the rights or duties of the licensee as at present; for that purpose we must look into those terms as modified by the provisions of the Supply Act as It is now. It was also urged on its behalf that there is no question of vested rights in these cases; herein we are only concerned with the procedure to be adopted in modifying the charges fixed in 1952. In Mohar Singh 's case(1) this Court laid down that the provisions of section 6(c)	 (d) and (e) of the relating to the consequences of the repeal of a law are applicable not only when an Act or Regulation is repealed simpliciter but also to a case of repeal and simultaneous enactment re enacting all the provisions of the. repealed law. In the course of its judgment this Court observed that when the repeal is followed by a fresh legislation on the same subject	 the Court has undoubtedly to look into the provisions of the new Act but that only for the purpose of determining whether they indicate a different intention. The line of inquiry would be	 not whether the new Act keeps alive the old rights and liabilities but whether it manifests any intention to destroy them. In Deep Chand 's case(2) this Court was considering the effect of repugnancy between a State Act and a Central Act. The observations made in that context	 we think	 have no bearing on the point in issue in this case. It is true that when an existing Statute or Regulation is repealed and the same is replaced by fresh Statute or Regulation unless the new Statute or Regulation specifically or by necessary implication affects rights created under the old law those rights must be held to continue in force even after the new Statute or Regulation comes into force. But in the cases before us there is no question of affecting any vested right. There is no dispute that the charges fixed can be altered. The controversy relates to the procedure to be adopted in altering them. That controversy does not touch any vested right. The procedure in question must necessarily be regulated by the law in force at the time of the alteration of the charges. Section 57 of the Supply Act as it stands now lays down that the provisions of Sch. VI shall be deemed to be incorporated in the licence of every licensee not being a local authority	 in 'the case of a licence granted before the commencement of the Act from the date of the commencement of the licensee 's next succeedmg year of account. Admittedly the licence with which. we are concerned in these cases was granted even before the Supply Act was enacted. Therefore quite clearly the licence in question is governed by the present section 57. Hence we have to read into that licence the provisions contained in Sch.1 VI. If any of the earlier (1) ; (2) [1959] 2 Supp. S.C.R. 8. 8 47 provisions in the licence either as they stood when the licence was originally granted or as they stood modified as per the provisions of the Supply Act prior to its amendment in 1956 are in consistent 	with the provisions of Sch. VI or section 57(A) as they are now they must be held to be void and of no effect. In other words we must read into the licence the provisions of Sch. VI and strike out therefrom such terms as are inconsistent with those provisions and thereafter give effect to the same. For determining the 	 rights and duties of the licensee as at present we have only to look into the terms of the licence as modified by Sch. We cannot go behind them. That much is clear from the language of the Supply Act. The intention of the legislature is clear and unambiguous. Therefore there is no need to call into aid any rule of statutory construction or any legal presumption. Further no reason was advanced before us	 nor can we conceive of any why those who obtained licenses prior to the amendment of Supply Act in 1956 should be in a more disadvantageous position than those who got their licenses thereafter. Correspondingly we fail to see why those who are served by licensees who obtained their licences prior to the amendment of the Supply Act in 1956 should be placed in a better position than those served by licensees who obtained their licenses thereafter. After all	 every law has some reason behind it. Section 57(A)(2)(e) was intended to meet the changing economic circumstances. The purpose behind the new provisions appears to be to permit the licensees to so adjust their charges as to get reasonable profits. 	 But at the same time a machinery has been provided to see whether any excess charges have been levied and if levied	 get the same refunded to the consumers. The law declared by the Amending Act does not affect any	 right or privilege	 accrued under the repealed provision. It merely prescribes as to what could or should be done in future. Therefore there is no basis for saying that it affects vested rights. For finding out the power of the licensee to alter the charges one has to look to the terms of the licence in the light of the law as it stands the past history of that law being wholly irrelevant. If the terms of the licence	 including the deemed terms permit him to unilaterally alter the charges then he has that right. If we merely look at those terms	 as we think we ought to	 then there is no dispute that the respondent was within its rights in enhancing the charges as admittedly it has followed the procedure prescribed by law. We also do not agree with Mr. Chagla in his contention that there is no inconsistency between the present scheme relating to the enhancement of charges vis a vis the scheme provided under the Supply Act prior to its amendment in 1956. The two schemes are substantially different. ' Under the former scheme once the Government fixes the charges the licensee cannot alter 848 it but at present at the end of the period order the licensee has a unilateral right to accordance with the conditions prescribed fixed in the Government enhance the charges in in the VI Schedule. Therefore in view of section 57 the provisions contained in that schedule have an over riding effect. In Amalgamated Electricity 'Co.	 Ltd. vs N. section Bhathena and Anr.(1) this Court was called upon to consider the scope of section 57.(A) and the Sch. VI as it stands now. Therein the controversy was whether the appellant therein was entitled ' to levy charges more than the maximum charges prescribed in its licence issued in 1932. It may be noted that in that case the notice of enhancement of the charges was given on September 25	 1958. This Court held that the maximum stipulated in the licence no longer governed the. right of the licensee to enhance the charges; his rights were exclusively governed by the provisions contained in paragraph 1 of Sch. VI of the Supply Act. It is true that in that case this Court was considering the right of the licensee under the Supply Act vis a vis his right under the licence granted under the but that difference is not material. What this Court in fact considered was the right of the licensee under the existing law to enhance the charges. Dealing with the scope of paragraph 1 of Sch. VI	 Ayyangar	 J. who spoke for the majority observed thus : "para 1 of Sch. VI both as it originally stood and as amended	 as seen already	 empowered the licensee "to adjust his rates	 so that his clear profit in any year shall not	 as far as possible	 exceed the amount of reasonable return". We shall reserve for later consideration the meaning of the expression "so adjust his rates". ' But one thing is clear and that is that the adjustment is unilateral and that the licensee has a statutory right to adjust his rates provided he conforms to the requirements of that paragraph viz.	 the rate charged does not yield a profit exceeding the amount of reasonable return. The conclusion is therefore irresistible that the maxima prescribed by the State Government which bound the licensee under the Electricity Act of 1910 no longer limited the amount which a licensee could	 charge after the Supply Act	 1948 came into force since the "clear profit" and "reasonable return" which determined the rate to be charged was to be computed on the basis of very different criteria and factors than what obtained under the Electricity Act." 	 For the reasons above	 these appeals fail and they are dismissed with costs. One hearing fee. G.C. Appeals dismissed.

The respondent held a licence for the supply of Electricity under the ' in the Godhra area of undivided BombaY. On the creation of the State of Gujarat the area went to that State. The Electricity (Supply) Act came into force in 1948 and under it the condi tions in Schedule VI thereof were deemed to be incorporated in the licence of every licensee. Under section 57 (2) (c) of the ' Act the Government could fix the rates for supply of electricity and under cl. 1 of the Schedule VI a licensee could reduce the rates for keeping the profit at a reasonable level. A licensee had no	 power to enhance the rates except by requesting the Government to fix new rates on the recommendation of a fresh rating committee. In 1952 the Covernment fixed certain rates on the recommendations of a rating committee. In 1956 the Supply Act of 1948 was amended. By section 57A(1) (e) of the amended Act the rates fixed by the Government under section 57(A)(1)(d) on the recommendation of a rating committee were to enure for a maximum of three years. Under of the amended Schedule VI the licensee shall so adjust his charges Cl. the sale of electricity whether by enhancing or reducing them that his clear profit in any year of account shall not as far as possible exceed the amount of reasonable return. In 1963 the respondent enhanced the rates of supply without having them fixed by the Government on the recommendations of a rating committee. The appellants who were consumers of electricity in the Godhra area filed suits seeking	 to restrain the respondent from enforcing the enhanced charges. The suits were decreed by the trial court and the decrees were 'confirmed by the first appellate court and in second appeal by a single Judge. In Letters Patent appeal however the High Court held that under the Supply Act as amended in 1956 the respondent had a unilateral right to enhance the charges subject to the conditions prescribed in	 Schedule VI of the Act. The appellants Came to this Court contending that they had a vested right in. the rates fixed by Government in 1952	 that under the amended Act the respondent did not have a unilateral right to enhance those rates	 and that the amended provisions not being retrospective nor inconsistent with the old provisions the charges fixed by the Government in 1952 must in view of section 6 of the continue to be in operation. HELD : The law declared by the Amending Act does not affect any right or privilege	 accrued under the repealed provision. It merely Prescribes as to what can or should be done in the future. Therefore there is no basis for saying that it affects vested rights. [847 F] For finding out the power of the licensee to alter the charges one has to look at the terms of the license in the light of the law as it stands	 the 837 past history of that law being wholly irrelevant. If the terms of the licence	 including the deemed terms permit him to unilaterally alter the charges then he has that right. In the present case looking at those terms	 the respondent was certainly within its rights in enhancing the charges as admittedly it had followed the procedure prescribed by law. [847 F G] The contention that there was no inconsistency between the present scheme relating to the enhancement of charges vis a vis the scheme provided under the Supply Act prior to its amendment in 1956 could not be accepted. The two schemes are substantially different. Under the former scheme once the Government fixed the charges the licensee could not en hance them but at present at the end of the period fixed in the Government order the licensee has a unilateral right to enhance the charges in accordance with the conditions prescribed in Schedule VI. Therefore in	 view of section 57 the provisions contained in that Schedule have an overriding effect. [847 H 848 A] The intention of the legislature being clear and unambiguous there was no need to call into aid any rule of statutory construction or any legal presumption. Further	 there was no reason why those who obtained licences prior to the amendment of the Supply Act in 1956 'should be in a more disadvantageous position than those who got their licences thereafter. Correspondingly there was no reason why those who are served by licencees who obtained their licences prior to the amendment of the Supply Act in 1956 should be placed in a better position than those served by licensees who obtained their licences thereafter. [847 C] Section 57(A)(1)(e) was intended to meet the changing economic circumstances. The purpose behind the new provisions appears to be to	 permit the licencees to adjust their charges to get reasonable profits. But at the same time a machinery has been provided to see whether any excess charges have been levied and if levied 'get the same refunded to the consumers.[847 E] In view of the above considerations and findings the appeals must fail.
