Kerala State Electricity Board v. Prabhu (Reddy, J.)

A B c D E F AUGUST 26, 1986 IO. CHINNAPPA REDDY AND M.M. DUTT, JJ.] _Electriciiy Supply Act, 1948-Section 59-Electricity_ _Board-_ _Formulation_ _of price structure intended_ _to_ _yield sufficient_ _revenue-_ _Examination_ _of_ _by Court-Electricity Tariff-Upward_ _revision-_ _Whether valid._ The upward re•ision of Electricity Tariff made by the appeUantBoard in 1980, 1982 and 1984 was challenged in the High Court by the respondents on the ground that the Electricity Board acted outside its statutory authority hy formulating a price structure intended to yield sufficient revenue to offset not merely the expenditure properly chargeable to the revenue account for the year as contemplated by s. 59 of the Electricity Supply Act, 1948, but also expenditure not so properly chargeable and that had s. 59 been strictly followed and had items of expt..tditure not chargeable to the revenue account for the year been excluded, the revised tariff would have resulted in the generation of a surplus far beyond the contemplation of s. 59 of.the Act. The FuU Bench of the High Court struck down the tariff revisions holding that in the absence of specification by the Government, a Board was not entitled to generate a surplus at all and it had acted entirely outside its authority in generating a surplus to be adjusted against items of expenditure not authorised to be met from revenue receipts. The notifications prescribing, revised tariffs were, therefore, struck down. KERALA STATE ELECTRICITY BOARD, ETC. _/_ _v._ S.N, GOVINDA PRABHU & BROTHERS AND OTHERS ETC. G In appeal to this Court on behalf of the appellant it was contended, that the 1978 Amendment of the Electricity Supply Act 1948 did not effectively improve matters as many State Governments did not specify the quantum of snrplus. Parliament bad, therefore, to intervene once again and that was in 1983 to th the statutory minimnm surplus, which was made clear by the 1983 Amendment which stipulated a H minimnm of 3 per cent surplus in the absence of specification by the 628 ' KER. STATE E.B. '· PRA.BHU IREDDY,J.J 629 State Government which. had the liberty to specify a higher percentage than three. It was further contended, by submitting statements, that in the years 1978-79 to 1981-82, which were extraordinary years, but for the boom in the sale of energy to neighbouring States. there would have been a serious deficit in every one of these years and that it is clear that ·the Electricity Board has not been earning huge profits and generating large surpluses as suggested by the. consumers, and consequently ·the upward revision of the electricity tariff was justified. On behalf of respondent-consumers it was contended: ( l) that the Electricity Board was barred from conducting its operations on. commercial lines so as to earn a profit; (2) that in the absence of specifications by the State Government the position would be as it was before the 1978 Amendment, i.e. the Board was to carry on its affairs and adjust the tariffs in such a manner as not to incur a loss; (3) that while interest which accrued to be revenue expenditure, arrears of interest which accrued during the previous years and had not been paid could not be so considered; (4) that the 1980 Committee took into consideration the anticipated augmentation of the generating capacity from the proposed **new power stations whereas these pro,jects were not commissioned till** 1984 and thus the cost structure arrived at by the Committee was vitiated: (5) that the Committee did not take into account the financial position of the Board as brought out by the year 1978-79 which showed that the Board had no need for enhancing the rates; (6) that the 1980 Committee having taken as the basis the 1982 projected cost, so as to maintain price stability for a period of live years, it was not proper to revise the tariff again in 1982; and (7) that it was not open to the Board to give favoured treatment to Low Tension Domestic and Agricultural Consumers at the cost of the rest of the consumers. Allowing the appeals of the Electricity Board, HELD: I. The judgments of the High Court are set aside and the validity of the notifications revising the tariffs upheld. The Board will reconsider the revised tariff introduced in 1980 in regard to Low Tension Industrial and ·Low Tension Commercial Consumers only, with liberty· to fix separate rates, if necessary for the years 1980 and 1981. [6$9D-E] 2. A State Electricity Board created under the Electricity Supply Act is an instrumentality of the State subject to the same constitutional and public law limitations as are applicable to the Government including the principle of law which inhibits arbitrary action by the Government. His a public utility monopoly undertaking~ Service and not profit A B c D E F G H A B _c_ 0 F G H 630 SUPREME COURT REPORTS I 1986] 3 S.C. R. should inform its actions and it must manage its affairs on sound economic principles. No public service undertaking can afford to ignore business principles which are as esssential to public service undertakings as to Commercial ventures. If the Board borrows sums either from the Government or from other sources or by the issue of debentures and bonds, the Board must of necessity make provision year after year for the payment of interest on the loans taken by it and for the repayment of the capital amounts of the loans. If the Board is unable to pay interest in any year for want of sufficient revenue receipts, the Board must make provision for payment of such arrear of interest in succeeding years. The Board is not expected to run on a bare year-to-year survival basis.

Section 18(a) prescribes that it is the duty of the Board to arrange for the supply of electricity that may be required within the State and for the transmission and distribution of the same, _in the most_ _efficient and_ economical manner and s. 49(2) (b) requires the Board to have regard, in fixing uniform tariffs, the coordinated development of the supply and distribution of electricity within the State _in_ _the_ _most_ _efficient and economical_ manner. both with particular reference to those areas which are not for the time being served or adequately supplied with electricity. The principles of efficiency and economy are, therefore, not foresaken but resolutely emphasised. l64SB-D) , 4. Pure profit motive, unjustifiable even in the case of a' private trading concern, can never be the sole guiding factor in the case of public enterprise. If profit is made not for profit's sake but for the purpose of fulfilling, better and more extensively, the obligation of the services expected of it, it cannot be said that the public enterprise acted beyond its authority. [648G-H: 649A] 5. The total operational cost would include the interest on the capital outlay out of the national exchequer and that there was no justification to run a public utility monopoly service undertaking merely as a commercial venture with a view to make profits. [649D-E] 6. A reading ofs. 59 (as amended in 1978) plainly indicates that it is the mandate of Parliament that the Board should adjust its tariffs so that after meeting the various expenses properly required to be met a A B c D E F G H #,,i. **1t** KER.

The original negative approach of functioning so as not to suffer a loss is replaced .hy the positive approach of requiring a surplus to be created. The quantum of minimum surplus is to be specified by the State Government, Since many State Governments did not specify the quantum of surplus. s. :;9 was again amended in 1983, **which stipulates** ~· **1niniinum** **of** **J** **per rent surplus** **in** **the absence** **of** specification by the State Government which has the liberty to specify a higher percentage than three.

The failure of the Government to specify the surplus which may be generated by the Board cannot prevent the Board from generatfng a surplus.after meeting the expenses required to ·be met. The Board may not allow its character as a 11ublic ·utility undertaking to be changed into that of a profit motivated private trading or manufacturing house. Neither the tariffs nor the resulting surplus may reach such lteights as to lead to the inevitable conclusion that the Board has shed its public utility character. When that happens the Court may strike down the revision of tariffs as plainly arbitrary. But not until then. Not, merely because a surplus has been generated, a surplus which can by no **means be said to** **be** **extravagant.** **'l'he** **Court will then refrain from** touching the tariffs.

Readings. 59 alongwith ss. 49, 67, 67A etc. it is noticed that B _c_ fl F I II 632 SUPKEME COUKI REPORTS [ 1986] 3 S.C. R. the Electricity Supply Act, 1948, requires the Electricity Board to fol low a particular method of accounting and it is on the basis of that method of accounting that the Board is required to generate a surplus. Broadly, s. 59 requires that a surplus should be left from the total revenues, in any year of account, after meeting all expenses properly chargeable to revenues. Apart from subventions which may be received from the State Government, which depend entirely on the bounty of the Government, the only revenue available to the Board are the charges leviable by it from consumers. [65311-D I IO. Section 59 (I) specifies "operating maintenance and management expenses', 'taxes (if any) on income and profits', 'depreciation and interest payable on all debenture, bonds and loans', as included in 'expenses properly chargeable to revenues'. Section 59 (2) stipulates that in specifying the surplus, the Government shall have due regard to the availability of amounts accrued by way of depreciation and the liability for loan amortization. It also stipulates that a reasonable sum to contribute towards the cost of capital works and a reasonable sum by way of return on the capital provided by the State Government should be left in the surplus. This sub-section, thereforf, makes it clear that the Board is to provide for (I) loan amortization; (2) contribution towards the cost of capital works; and (3) return on the capital. Section 67 prescribes the prfority to be observed by the Board in the matter of discharging the liabilities enumerated therein out of its revenues. First **the operating maintenance and management expenses have to** **be** **met,** next provision has to be made for payment of taxes on Income and -Profits and thereafter various items of expenditure are mentioned in order of priority. If any amount is left after the discharge of the liabilities enume rated in s. 67, the balance shall be utilised for the other purposes sµecilied ins. 59 in such manner as the Board may decide. [653E-H; 654A-B) I I. Payment of interest is expressly mentioned among the liabilities to be discharged, as also repayment of principal of loans becoming due for payment in the year. Clause (vi) of sub-s. (I) of s. 67 makes it clear that repayment of principal of any loan guaranteed by the State Government will include loans which became due for payment in the year as well as loans which became due for payment in any previous year and had remained unpaid. [654B-C] 12. Under the scheme of the Act principal amount falling due in any year has to be met from the revenue receipts of the year. No pay ment towards principal could be made or accepted, if interest of previ ., KER. STATE E.B. _v._ PRABHU [REDDY, J.[ 633 ous years continued to be outstanding. The very provision for repayment of capital necessarily implies payment of all interest accrued upto the date of repayment of the capital. If arrears of interest cannot be paid from revenue receipts, such arrears cannot be paid from the capital receipts. What may be paid out of capital receipts and the circumstances under which the payment may be made are expressly provided in s. 67 (2) which says that if for any reasons beyond the control of the Board the revenue receipts in any year are not adequate to meet the **operating, maintenance and management expenses, taxes** **on** **income** and profits, and the liabilities referred to in clauses (i) and (ii) of s. 67 (1), then the shortfall shall be paid out of its capital receipts with the sanction of the State Government. There is no doubt that arrears of interest are, under the scheme of accounting contemplated by the Act, required to be paid out of revenue receipts of the Board and are expenses properly chargeable to revenues within the meaning of that expression ins. 59 of the Act, [654D-G] 13. The Legislature has clarified the aforesaid position by the Amending Act 16 of 1983 which came into force from April 1, 1985. A separate section, s. 67 A has been introduced alongwith a consequential amendment of s. 67 providing that interest of loans advanced under s. 64 or deemed to have been advanced under s. 60, which is charged to revem~es in any year may be paid out of revenue receipts of a year only after all other expenses referred to in s. 59 (l) are met and further providing that so much of interest as is not paid in any year by reason of the priority mentioned in s. 67 A shall be deemed to be a deferred liability to he discharged in accordance with provision of s~ 67 A in the subsequent year or years. These provisions show beyond doubt that payment of arrears of interest is an expense properly chargeable to the revenues under the scheme of the Act. [654G-H; 655A-B] L 14. Statements containing details of interest.payable in each year of accounting, the arrears of interest due and payable, the total revenue receipts and some other relevant particulars, in the present case show that the Electricity Board bas not been earning huge profits and generating large surpluses as suggested by the consumers. Once it is established there is hardly any revenue surplus left after meeting the expenses required to be met by s. 59, the complaint of the consumers that there was no justification for the tariff increase because of large surpluses earned by the Board, loses all force. [655G; 656H; 657 A] 15. As regards the rates of tariff for the relevant years, in the case of Extra High Tension and High Tension Industrial Consumers, \he A B c D E F G H 634 SUPREME COURT REPORTS [1986] 3 S.C.R. - \ change effected by the 1980 revision was minimal but on the higher side in 1982. In. the case of Low Tension Industrial and Commercial Consumers, the change effected in 1980 was very steep but tended to come down in 1982. [6571l-E] B _c_ D G H .16. On the whole, it cannot possibly be said that the rates have been so fixed by the Electricity Board as to throw a heavy burden on any section of the consumers without regard to their ability to pay without regard to the nature of the supply and purpose for which the supply is required. 1980-81 and 1981-82 were the years when accounts of the Electricity Board recorded a net surplus after meeting all expenses including interest charges. It is, therefore, desirable that the Board may re<.'Onsider the 1980 \ariff for Low Tension Commercial and Low Tension Industrial Consumers. [658A-B[ 17. A large part of expenditure involved in the setting up of the new projects had to be met in the several years preceding the actual commissioning of the projects. Therefore, it is not correct to say that the cost structure arrived at by the Tariff Committee was in any way affected by the non-commissioning of the new projects betw_een 1980 and· 1982. [6>Xl -111 18. The rise in revenue receipts in the year 1978-79 due to the unprecedented sale of energy to neighbouring States, a special situation which was the result of peculiar circumstances, which prevailed that year and continued to prevail for a few years thereafter, cannot be taken as a permanent phenomenon to every year. [658E-F[ 19. The actual cost of producing energy in 1981-82 and 1982-83 had risen much above the projected 1982 costs and therefore the 1982 Committee had no option but to again consider further revision of the **tariff.** It is **not within the province** **of this Court to examine the price** structure in minute detail if it is established that the revision of tariff is not arbitrary and is not the result of the application of any wrong principle. [658G-H] 20. Section 49 (3) expressly reserves the power of the Board, if it considers it necessary or expedient, to fix different tariff for the supply of electricity to any person having regard to the geographical position of any area, the nature of the supply and purpose for which supply is required and other relevant factors.

The first two revisions were struck qown by 'a Full Bench of three judges by ·a majority of two to one and, later, all three revisions were struck down by a Full Bench of Five judges by m~jority of four to·one. The principal ground of challenge and that which was accepted by the High Court was that the Kerilla State Electricity Board acted outside its ·statutory authority ty formulating a price structure intended to yield sufficient revenue to off set not merely the expenditure properly .. chargeable to the revenue account for the year as contemplated by s. _59_ of the Act but also expenditure not so properly chargeable. Had s. D E F G· H . ~ ' ; 636 SUPREME COURT REPORTS. { 1986] 3 S.C. R.

According to the High Court, in the absence of a· specification by the Government the Board was not en- · B ., titled to generate a surplus at all and it acted entirely outside its authority in generating a surplus to be adjusted against items of expenditure not authorised to be met from the revenue receipts.

We have, however, extracted that provision also for a better understanding of s. 59 as it stood before the 1983 amendment. We consider that for the purpose of understanding and construing s. 59, as it stood before the 1983 amendment, we are entitled to take int'? consideration the Parliamentary exposition contained in the 1983 amendment.

STATE E.B. _v._ PRABHU [REDDY, J.J 639 We think that it is necessary at this stage itself to refer to some of the other important provisions of the Electricity Supply Act. Section 18 prescribes the general duties of the Board and, it is as follows: "18. General Duties of the Board-Subject to the provisions of this Act, the Board shall be charged with the following general duties, namely: #, .L _f_ (a) to arrange, in co-ordination with the Generating Company or Generating Companies, if any, operating in the State, for the supply of electricity that may be required within the State and for the transmission and distribution of the same, in the most efficient and economical manner with particular reference to those areas which are not for the time being suppiied or adequately supplied with electricity; (b) to supply electricity as soon as practicable to a lincensee or other person requiring such supply if the Board is competent under this Act so to do; (c) to exercise such control in relation to the generation, distribution and utilisatio_n of electricity within the State as is provided for by or under this Act; (d) to collect data on the demand for, and the use of, electricity and to formulate perspective plans in co-ordination with the Generating Company or Generating Companies, if any, operating in the State, for the generation, transmission and supply of electricity within the State; (e) to prepare and carry out schemes for transmission, distribution and generally for promoting the use of electricity within the State; and (f) to operate the generating stations under its control in co--0rdination with the Generating Company or Generating Companies, if any, operating in the State and with the Government or any other Board or agency having control over a powet syste·m."

Section 67B which was introduced by Act 16 of 1983 defers payment of interest on loans advanced by the Stat,e Government until - after all other expenses are met. It is in th¢ following terms: G "67 A Interest on loans advanced by State Govt. to be paid only after other Expenses. Any ji)terest which is payable on loans advanced under section 64 or deemed to have been advanced under section 60 to the !Joarcl by the State Government and which is ch11rged to revenues in ;iny year may If ;\ B _c_ D E F G II 644 SUPREME COURT REPORTS . . \ 19861 3 S.C. R. be paid only out of the balance of the revenues. if any. of that year which is left after meeting all the other expenses referred to in sub-section (1) of section 59 and so much of such interest as is not paid in any year by reason of the provisions of this section shall be deemed to be deferred liability and shall be discharged in accordance with the provisions of this section in the subsequent year or years, as the case may be." Now, a State Electricity Board created under the provisions of the Electricity Supply Act is an instrumentality of the State subject to the same constitutional'and public law limitations as are applicable to the government including the Principle of law which inhibits arbitrary action by the Government. (see _Rohtas Industries_ v. _Bihar State Electri-_ _city Board,_ [1984] 3 SCR 59). It is a public utility monopoly undertaking which may not be driven by pure profit motive not that profit is **4** to be shunned but that service and not profit should inform its actions. 1 t is not the function of the Board to so manage its affairs as to earn the maximum profit even as a private corporate body may be inspired to earn huge profits with a view to paying large dividends to its sharehclders. But it does not follow that the Board may not and need not earn profits for the purpose of performing its duties and discharging its obligations under the statute, It stands to common sense that the Board must manage its affairs on sound economic principle:s. Having ventured into the field of Commerce, no public service undertaking can afford to say it will ignore business principles which are as essential to public service undertakings as to Commercial ventures. (see _Lord_ _Scarman_ _in_ _Bromely_ v. _Greater London Council,_ [1982] 1 ALL ER 129). If the Board borrows sums either from the Government or from other sources or by the issue of debentures and bonds, surely the Board must of necessity make provision year after year for the payment of interest on the loans taken by it and for the repayment of the capital amounts of the loans. If the Board is unable to pay interest in **any year for want** **of sufficient reveiiue·receipts, the Board must make** provision for payment of such arrear of interest in succeeding years. The Board is not expected to run on a bare year-to-year survival basis. It must have its feet firmly planted on the earth. It must be able to pay the interest on the loans taken by it; it must be a~le to discharge its debts; it must be able to give efficient and economic service; it must be able to continue the due performance of its services by providing for depreciation etc; it must provide for the expansion of its services, for no one can pretend the country is already well supplied with electricity. Sufficient surplus has to be generated for this purpose. That we KER. STATE E.B. '· PRABHU [REDDY.J.l 64'i take it is what the Board would necessarily do if it was an ordinary commercial undertaking properly and prudently managed on sound commercial lines. Is the position any different because the Board is a public utility undertaking or because of the provisions of the Electricity Supply Act? We -do n~t think that either the character of Electricity Board as a Public Utility· Undertaking or the provisions of the Electricity Supply Act preclude the Board from managing its affairs on sound commercial lines though not with a profit-thirst. It may be noticed here that s. 18(a) prescribes it as one of the duties of the Board to arrange for the supply of electricity that .may be required within the State and for the transmission and distributionof the same, _in the most_ _efficient and economical manner_ ands. 49(2) (b) requires the Board to have regard, in fixing uniform tariffs, the coordinated development of the supply and distribution of electricity within the State _in_ _the_ _most_ _efficient and economical manner,_ both with particular .reference to those areas which are not for the time being served or adequately supplied with electricity. The principles of efficiency and economy are, therefore, not forsaken but resolutely emphasised. Now if we tum to s. 'i9. what do we find? Though at one time it appears to have been thought that it was enough if the Board did not carry on its operations at a loss it was realised that the statutory admonition to the Board should be positive and not negative and that the Board should be given an affirmative and self-assuring direction. So s. 59 was amended in 1978. The Statement of Objects and Reasons says. \ B c D F G ,l. ( t "3. Section 59 of the Electricity (Supply) Act is proposed to be amended by clause 8 of the Bill to give a positive direction to the Electricity Boards that after meeting all their expenses, there should be provision for a surplus for contribution towards immediate investment needs. A similar amendment is also proposed to be made in regard to the Generating Companies by inserting a new sub-section (3A) in section 75A by clause 18 of the Bill." It was found that the 1978 amendment did not effectively improve matters as many State Government did not specify the quantum of surplus. Parliament had, therefore, to intervene once again to fix a statutory minimum surplus. The Statement of Objects and Reasons relating to the 1983 amendment may also be extracted and it is as follows: "Though section 59 of the Act, as amended in· 1978, casr.1 _an_ _obligation on the State Government has so far specified_ _the quantum_ _of any surplus._ At present there is no uni- H A B _c_ D E F G H 646 SUPREME COURT REPORTS l 1986] 3 S.C. R. fonnity in the manner of classification and presentation of acoounts of the Boards and this renders inter-Board com- ... parison of financial performance difficult. _It is also con-_ _sidered necessary to re-arrange_ _the_ _priorities with regard to_ _distribution revenues_ _of the Boards_ . It is, therefore, proposed to amend the Act (a) to provide that each Board shall have a surplus which shall not be less than three per cent, _or such higher per-_ ·-1 _centage_ _as_ _the State Government may specify_, of the value of the fixed assets of the Board in service at the beginning oftheyear; · (b) to re-arrange the priorities for distribution of revenues of the Boards; (c) ·to bring the financial reporting system of the Boards in line with commercial accounting practice; and (d) to empower with a view to securing uniformity in the manner of classification and presentation of accounts, the Central Government to prescribe the fonns in which the accounts of the Board and other records in relation thereto may be maintained." - ~ A plain reading of sec. 59 (as amended in 1978) plainly indicates that it is the mandate of Parliament that the Board should adjust its tariffs so that after meeting the various expenses properly required to be met a surplus is left. The original negative approach of functioning so as not to suffer a loss is replaced by the positiv~ approach of requir- --'., ing a surplus to be created. The quantum of surplus is to be specified by the State Government. What the State Government is to specify is J the minimum surplus. This is made clear by the 1983 amendment which stipulates a minimum of 3 per cent surplus in the absence of specification by the State Government which has the liberty to specify a higher percentage than three. That s. 59, as it stood before 1983 contemplated a minimum surplus was also the view expressed by this court in _Rohtas Industries_ v. _Bihar State Electricity Board_ (supra). where it was said, "Under the above provisions, the Board is under a statutory obligation to carry on its operations and ad just its + ... KER. STATE E.B. _v._ PRABHU [REDDY,J.[ 647 tariffs in such a way to ensure that the total revenues earned in any year of account shail after meeting all expenses chargeable to revenue, leave such surplus as the State Government may, from time to time, specify. The tariff fixation has, therefore, to be so made··as to raise sufficient revenue which will not merely avoid any net loss being incurred during the financial year but will ensure a profit being earned, the rate of _minimum_ profit to be earned being such as may be specified by the State **Government."** Shri Potti, learned Counsel for the consumers placed great reliance on the observations of this Court in _Kera/a State Electricity_ _Board_ v .. _Indian Aluminium Co.,_ [1976] 1SCR5'i2; _Bihar State Electri-_ _city_ _Board_ v. _Workmen,_ [1976] 2 SCR 42 and _Dr._ _P._ _Na/la Thamby_ _Thera_ vc _Union of India_ _&_ _Ors.,._ (1984 I 1 SCR 709 to contend that the Electricity Board ·was barred from conducting its operations on com~ mercial lines so as to earn a profit. In the first case, the· observations relied upon were. . "Furthermore, Electricity Boards are not trading corporations. They are public service corporations. _They have_ _to_ _function without any profit motive._ Their duty is to promote co-ordinated development of the generation, supply and distribution of electricity in the most efficient and economical manner with particular reference to such development in areas not for the time being served or adequately served by any licensee (section 18). The only injunction is that .as far as practicable they shall not carry on their operations at a loss (section 59). They get subventions from the State Governments (Section 63). In the discharge of their functions they are guided by directions on questions of policy given by the State Governments (Section 78A). There are no shareholders and.there is no distribution of profits." In the second case the court observed, "The Electriciiy Board is not an ordinary oommercial concern. It is a public service institution. It is not expected to make any profit. It is expected to extend the supply of electricity to unseIVed areas without reference to considerations of loss that might be incurred as a result of such extensio11." .·\ IL D E I (; A B c D E **F** G 648 SUPREME COURT REPORTS [1986] 3 S.C.R. In the third case. where the court was considering the position of the Indian Railways it was observed, "The Indian Railways are a socialised public utility undertaking: There is at present a general agreement among writers of repute that the price policy of such a Public Corporation should neither make a loss nor a profit after meeting all capital charges and this is expressed by covering all costs or breaking even; and secondly, the price it charges for the services should correspond to relative costs. Keeping the history of the growth of the Railways and their functioning in view, tlie commendable view to accept may be that the rates and fares should cover the total cost of service which would be equal to operational expenses, interest on investment, depreciation and payment of public obligations, if any. We need not, however, express any opinion about it." - ••••••••.•••..••••..•••.••••••.•••••.••..•.•••.••.. "We have said earlier that the Railways are a public utility service run on monopoly basis. Since it is a public utility, there is no justification to run it merely as a commercial -. venture with a view to making profits. We do not knowat any rate it does not fall for consideration here-if a monopoly based public **utility** should ever be .a commercial venture geared to support the general revenue of the State but there is not an iota of hestitation in us to say that the common man's mode of transport closely connected with -~ the free play of this fundamental right should not be. We agree that the Union Government should be free to collect the entire operational cost which would include the interest on the capital outlay out of the national exchequer. Small marginal profits cannot be ruled out. The. massive operation 'will reqttire a margin of adjustment and, therefore, marginal profits should be admissible." **l** We do not think that any of these observations is in conflict with what we have said. Pure profit motive, unjustifiable according to us even in the case of a private trading concern, can never be the sole guiding H . factor **in** the case of a public enterprise. If profit is made not for KER. STATEE.B. _v._ PRABHU [REDDY,J.] 649 profit's sake but for the 'purpose of fulfilling, better and more extensively, the obligation of the services expected of it, it cannot be said that the public enterprise acted beyond its authority. The observations in the. first case which were referred to us merely emphasised the fact that the Electricity Board is not an ordinary trading Corporation and that as 'a public utility undertaking its emphasis should be on service and not profit. In the second case, for example, the court said that it is not expected to make any profit and proceeded to explain why it is not expected to make a profit by saying that it is expected to extend the supply of Electricity to unserved areas without reference to considerations of loss. It is of interest that in the second case, dealing with the question whether interest cannot be taken into account in working out profits, the court observed, A B c D E F G H , -t' #, ### ., 'TheJacile assumption by the Tribunal that the interest should not be taken into account in working out the profits is not borne out by the provisions of the statute." In the third case, the court appeared to take the view that the railway rates and fares should cover operational expenses, interest on invest. ment, depreciation and payment. of public obligations. It was' stated more than once that the total operational cost would include the interest on the capital oµtlay out of the national. exchequer. While the court expressed the view that there was no justification to run a public utility monopoly service undertaking _merely_ as a commercial venture with a view to make ·profits, the court did not rule out but refrained from expressing any opinion on the question whether a public utility monopoly service undertaking should ever be geared to earn profits to support the general revenue of the State .. One·of the submissions which found favour with the High Court and which was seriously pressed before us was that in the absence of specification by the State Government the position would be as it was before the 1978 amendment, that is, the Board was carry on its affairs and adjust the tariffs in such a manner as not to incur a loss and no more. We do not agree with the submission for the reasons already mentioned. We may also refer here to the decision of the Privy Council in _Madras and Southern Mahratta Railway Company Ltd._ v. _Bezwada_ _Municipality,_ AIR 1944 PC 71 which affirmed the Judgment of the Madras High Court in _Madras and Southern Maharatta Railway Com-_ KER. STAIB E.B. _v._ PRABHU (REDDY,J.] 651 heights as to lead to the inevitable conclusion that the Board has shed its public utility character. When that happens the Court may strike down the revision of tariffs as plainly arbitrary. But not until then. Not, merely because a surplus has been generated, a surplus which can by no means be said to be extravagant. The court will then refrain from touching the tariffs. After all, as has been said by this court often enough 'price fixation' is neither the forte nor the function of the court. The occasional excursions that have been made into that field were at the request and by the agreement of the parties. This was made dear· by a Constitution Bench of seven judges of this Court in _Prag Ice·_ _and Oil Mil/sv. Union of India,_ [1978] 3 SCR 293 where it was said, "It is customary in price fixation cases to cite the oftquoted decision in Premier Automobilies Ltd. & Anr. etc. vs. Union of India which concerned the fixation of price of motor cars. It is time that it was realized that the decision constitutes no precedent in matters of price fixation and was rendered for reasons peculiar to the particular case. At page 535 of the Report Grover, J., who spoke for the Court, stated at the outset of the judgment. -''Counsel for all the parties and the learned Attorney General are agreed that irrespective of the technical or legal points that may be involved, we should base our judgment on examination of correct and rational principles and should direct deviation from the report of the Commission which was an expert body presided over by a former judge of a High Court only when it is shown that there has been a departure from· established principles or the conclusions of the Commission are shown to be demonstrably wrong or erroneous." By an agreement of parties the court was thus converted into a Tribunal for considering ~very minute detail relating to price fixation of motor cars. Secondly, as regards the escalation clause the Court recorded at page 543 that it was not disputed on behalf of the Government and the Attorney General accepted the position, that a proper method should be devised for escalation or de-escalation. Tillrdly, it is clear from page 544 of the Report that the Learned Attorney-General also agreed that a reasonable return must be allowed to the manufacturers on their investliieni. The decision thus proceeded partly on an agreement bet" A B c D E F G A B c 652 SUPREME COURT REPORTS [1986[ 3 S.C. R. ween the parties and partly on concessions made at the Bar. That is the person why the judgment in Premier Automobiles (supra) cannot be treated as a precedent and cannot afford any appreciable assistance in the decision of **price fixation cases."** The position was again clarified in _Rohtas Industries_ v. _Bihar State_ _Electricity Board_ (supra) : ·-! "As pointed out by this Court in Prag Ice & Oil Mills and another vs. Union of India, in the ultimate analysis, t.he mechanics of price fixation is necessarily to be left to the judgment of the executive and unless it is patent that there is hostile discrimination against a class of person, the processual basis of price fixation is to be· accepted in the generality of cases as valid." _)_ D On the question of appropriate pricing policy we may conve niently refer, at this juncture to what the Planning Commission had to say in the Seventh Five Year Plan. At page 128 of Vol. II in para 6.31 it was said, E F G H "6.31 The Sixth Plan had emphasised the need to give high priority to the evolution of a structure of enerb'Y prices which reflect true costs, curb excessive energy use and promote conservation of scarce fuels. Except in the case of oil, timely adjustments have not been made in the prices of coal and electricity to reflect the real costs. Energy pricing has not promoted, to the desired extent, inter-fud su bstirution. Energy users have generally not .adopted conservation measures already identified. While action is being taken to promote technologically energy-efficient equipment and processes, on the one hand, appropriate energy pricing policy would have to be followed, on the other hand, in order to induce economics in the use of energy in all sectors and encourage desired forms of inter-fuel substirution, including renewable energy wherever viable. The pricing of energy should not only reflect the true costs to the economy but also help to ensure the financial viability of the energy industries. This is particularly relevant in respect of coal and power industry. As we have said in the past, it is wrong to think that an adjustment in the prices of KER. STATE E.B. _v._ PRABHU [REDDY.).[ 653 a basic input like energy would aggrevate the inflationary situation; the costs to the economy are not reduced by not reflecting them in proper pricing. Indeed the continuance of .wrong pricing policy has a far more deleterious effect on the health of the economy than is often realised. The formulation of an integrated energy pricing structure on the above lines should receive the highest prioriiy in the beginning of the Plan period."" A B c D E F G H Turning back to sec. 59.a_nd reading it along with sections 49, 67, 67 A etc. we notice that the Electricity Supply Act requires the Electricity Board to follow a particular method of accounting and·it is on the basis of that method of accounting that the Board is required to generate a surplus. Broadly, sec. 59 requires that a surplus should be left. from the total revenues, in any year of accoun_t, after meeting all expenses properly chargeable to revenues. It has to be remembered that apart from subventions which may be received from the State Government, which depend entirely on the bounty. of the Government, the only revenues available to the Board are the charges leviable by it from consumers. Bearing this in mind, we may now consider what expenses are properly chargeable to revenues under the Electricity Supply Act. For this purpose, we may not be justified in having recourse to the principles of corporate accounting or the rules which determine what is revenue expenditure under the Indian Income-tax Act. It appears to us that the Electricity Supply Act prescribes its own special principles of accounting to be followed by the Board. To begin with s. 59(1) specifies 'operating maintenance and management expenses' 'taxes (if any) on income and profits', 'depreciation and interest payable on all debentures, bonds and loans',, as included in 'expenses properly· chargeable to revenues'. Section 59(2) further stipulates that in specifying the surplus, the Government shall have due regard to the availability of amounts accrued by way of depreciation and the liability for loan amortization. It also stipulates that a reasonable sum to contribute towards the cost of capital works and a reasonable sum by way of return on the capital provided by the State Government should be left in the surplus. This sub-section, therefore makes it clear that the Board is to provide for (1) !ban amortization (2) contribution towards the cost of capital works; (3) return on the capital. We may now turn to s. 67 which prescribes the priority to be· -Observed by the Boatd in the matter of discharging the liabilities enu ###### }. merated therein out of its .revenues. First the operating•maintenance and management expenses have to be met, next provision has to be A B c D E F G H 654 SUPREME COURT REPORTS 11986] 3 S.C.R. made for payment of taxes on Income and Profits and thereafter various items of expenditure are mentioned in order of priority. If any amount is left after the discharge of the liabilities en\imerated ins. 67 it is further provided that the balance shall be utilised for the other purposes specified in s. 59 in such manner as the Board may decide. Payment of interest is expressely mentioned among the liabilities to be discharged, as also repayment of principal of loans becoming due for payment in the year. Clause (vi) of sub-section (1) of sec. 67 makes it clear that repayment of principal of any loan guaranteed by the State Government will include loans which became due for payment in the year as well as loans which became due for payment in any previous year and had remained unpaid. The submission strenuously urged on behalf of the consumers before the High Court and before us was that while interest which accrued during the year might be properly considered to be reve!'ue expenditure, arrears of interest which accrued during the previous years and had not been paid could not be so considered. We fail to see why that should be so. Under the scheme of the Act principal amount falling due in any year has to be met from the revenue receipts of the year. It is difficult to understand how any payment towards principal could be made or accepted. If interest of previous years continued to be outstanding. The very provision for . repayment of capital necessarily implies payment of all interest accrued upto the date of repayment of the capital. If as argued on behalf of the consumers arrears of interest cannot be paid from revenue receipts, how then may such arrears be paid? Not from the capital receipts. What may be paid out of capital receipts and the circumstances under which the payment may be made are expressly provided in s. 67(2) which says that if for any reason beyond the control of the Board the revenue receipts in any year are not adequate to meet the operating, maintenance and management expenses, taxes on income and profits, and the liabilities referred to in clauses (i) and (ii) of s. 67(1), then the shortfall shall be paid out of its capital receipts with the sanction of the State Government. We do not therefore, have any doubt that arrears· of interest are, under the scheme of accounting contemplated by the Act, required to be paid out of revenue receipts of the Board and are expense properly chargeable ti:> revenues within the meaning of that expression in s. 59 of the Act. The Legislature has presently clarified the position by the amending Act 16 of 1983 which came into force from April 1, 1985. By this Act a separate section, s. 67 A has been introduced along with a consequential amendment of s. 67 providirig that interest on loans advanced under s. 64 or deemed to have been advanced under s. 60, which is charged to revenues in any _)_ KER. STATE E.B. r. PRABHU I REDDY, J.I 655 year may be paid out of revenue receipts of a year only after all other expenses referred to ins. 59(1) are met and further providing that so much of interest as is not paid in any year by reason of the priority mentioned in s. 67 A shall be deemed to be a deferred liability to be discharged in accordance with provision of s. 67 A in the subsequent year or years. In our view these provisions show beyond doubt that payment of arrears of interest is an expense properly chargeable to the revenues under the scheme of the Act. A c D E F G H ~ I We may now assess the factual situation, Shri Abdu!Khader, learned counsel for the Kerala State Electricity Board has placed before us statements containing details of interest payable in each year of· accounting, the arrears of interest due and payable, the total revenue receipts and some other relevant particulars. The statements have .. been prepared, taking the figures from the published annual accounts _-'(_ of the Kerala State Electricity Board. In the year of account 1978-79, the total revenue _receipts were Rs.8421.75 lakhs out of which the revenue earned by sale of energy to neighbouring States was Rs.2926. 73 Iakhs. After meeting operation amd maintenance expenses and depreciation the balance of revenue receipts was Rs.4161.60 lakhs. The amount of interest payable in the year of account was Rs. 1946.37 lakhs. The revenue surplus left after payment of interest in the year of account was therefore, Rs.2215.23 lakhs. The arrears of ,). interest accrued in previous years and not paid was Rs.4270.58 lakhs, since the revenue surplus available after meeting the current interest was Rs.2215.23. lakhs only there was a deficit of Rs.2055.35 lakhs. In the year of account 1979-80 the total revenue receipts were Rs.9124.90 lakhs which included revenue of Rs.3856. 15 lakhs from sale of energy ( to neighbouring States. After meeting operation and maintenance ex/"· penses and depreciation the revenue surplus left was Rs.3253.94 lakhs. The interest which became payable in the year of account was --.4.. Rs.2107.85 lakhs and after meeting it, the revenue surplus left was Rs.1146.09 lakhs. The old arrears of interest which could not be met fully in the ptevious year was Rs.2055.35 lakhs, Thus in the year of account year 1979-80, there was a deficit of Rs.909.27 lakhs. In the year of account 1980-81 the total revenue receipts were Rs. J0,686.54 lakhs •and this included a sum of Rs.4326.92 lakhs earned by sale of energy to neighbouring States. After meeting the operation and maintenance expenses and depreciation the revenue surplus left was Rs.3615.90 lakhs and after meeting interest of Rs.2369 .42 lakhs which had become payable in the year of account a revenue surplus of Rs.1246.48 lakhs was left. The,unpaid interest of previous years was Rs. 909 .27 lakhs A B c D E F G H 656 SUPREME COURT REPORTS [19861 3 S.C.R. and after meeting it we find for the first time a net surplus of Rs.337. 21 lakhs. In the year of account 1981-82 the total revenue receipts were Rs.12,144.02 lakhs which included revenue of Rs.4532.42 lakhs from sale of energy to neighbouring States. After meeting operation and maintenance expenses and depreciation; there was a revenue surplus of Rs.3183.77 lakhs. The total interest payable in the year of account was Rs.3105.15 lakhs, this left a revenue surplus of Rs.78.62 lakhs and 1980-81 & 1981-82 were extraordinary years when there was a boom in the sale of energy to neighbouring States consequent on the conditions prevailing there. In those years also it would be seen from the accounts that but for the boom in the siile of energy to neighbouring States there would have been a serious deficit in every one of those years. It is clear ; that the· Electricity Board has not been earning huge profits and generating large surpluses, as suggested by the consumers. Once we arriv.e at this position that there is hardly any revenue surplus left after ###### _1_ si~ce **there was no arrears of interest what was payaOle the net revenue** surplus was 78. 62. lakhs. In the year of account 1982-83 the total revenue receipts were Rs.11,228.40 lakhs which included revenue of Rs.1948.63 lakhs from sale of energy to neighbouring States. After meeting operation and maintenance expenses and depreciation the revenue surplus left was Rs.2810.60 lakhs. The interest which was payable in the year of account was Rs.3187 .62 lakhs and thus left a net revenue deficit of Rs.376.76 lakhs. In.the year of account 1983-84, the total revenue receipts were Rs.10,518.35 lakhs including revenue of Rs.175. 76 lakhs from sale of energy to neighbouring States. The revenue surplus after meeting operation maintenance expenses and depreciation was Rs.2246.30 lakhs. The amount of interest which had . + . become payable was Rs.3426.53 lakhs, the arrears of interest was Rs.376.76 lakhs leaving a total deficit of Rs.1556.99 lakhs. We may mention here that the annual account for the year 1978-79 to 1983-84 have been certified by the Accountant General and the annual accounts for the year 1984-85 are awaiting certification. The accounts awaiting certification show that in the year of account 1984-85, the revenue receipts after meeting operation and maintenance expenses and depreciation were 4692.92 lakhs, while the interest which had become payable during the year was Rs.3719 and the interest of the previous year Rs.1556.99 lakhs this left a deficit of Rs.584.00 lakhs. The revised estimates for the year 1985-86 show a revenue surplus of Rs.5567 .00 lakhs after meeting operation and maintenance expenses and depreciation. The interest payable during the year was Rs.4574.80 lakhs and the interest of previous year was Rs.584 lakhs. The left a surplus of Rs.409.00 lakhs. These figures show that 1978-79, 1979-80, ; l KER. STATE E.B. _v._ PRABHU IRED DY. J.I 657 meeting the expenses required to be met bys. 59, the complaint of the A ( consumers that there was no justification for the tariff increase because of large surpluses earned by the Board loses all force. We have examined the two reports of the Tariff Committees of the years 1980 and 1982 and the revised tariffs based on those reports B in the light of the legal and factual position explained by us. Before the + 1980 revision, the prevailing rates were, Extra High Tension: 8.81 ps per unit, High Tension Industrial: 14.98 ps per unit, Low Tension Domestic: 38 ps per unit, Low Tension Industrial: 14.15 ps per unit, Low Tension Commercial: 38 ps per unit, Low Tension Agricultural 14.15 ps per unit, Low Tension Commercial worked out the cost per ~ unit at 10.9, 18.6, 57.5, 43.5, 56.5 and 53.5 ps per unit respectively in c I that order, but recommended, in the same order, 11.55, 21.4, 38, 27.,5, 74 and 18 ps per unit respectively. However, the actual tariff rates as introduced in 1980 were 10.8, 18.24, 38, 24.5, 66 and 15 ps per unit. The 1982 Tariff Committee recommended rates of 24.5, 37.3, 47.5, 48, _r_ 55-70 and 34 ps per unit. The actual tariff introduced in 1982 was D 17.65, 27.24, 42.5, 24.5, 50-70 and 15 ps per unit. We notice that in the case of Low Tension Domestic and Agricultural consumers, the change is minimal. In the case of Extra High Tension and High Tension Industrial Consumers, the change effected by the 1980 revision was minimal but on the higher side in 1982. In the case of Low Tension Industrial and Commercial Consumers, the change effected in 1980 E was very steep but tended to come down in 1982. On the whole, it cannot possibly be said that the rates have been so fixed by the Electricity Board as to throw a heavy burden on any section of the consumers without regard to their ability to pay without regard to the nature of the supply and purpose for which the supply is required. Now do we , find that the pri1_1ciple of uniformity of tariffs has in any way been F sacrificed. But, as we mentioned a little earlier the Low Tension In ~ dustrial and Commercial 'tariff was subjected to a very steep rise in 1980 and brought down again in 1982 apparently in recognition of the fact that the raise had been too steep in regard to them in 1980. In the case of Low Tension Industrial Consumers, the tariff was increased from 14.5 ps per unit to 24.5 ps per unit in 1980 an·d maintained at the ##### r rate of 24.5 ps per unit in 1982. In the case of Low Tension Commer 1980 and brought down again in 1982 apparently in recognition of the fact that the raise had been too steep in regard to them in 1980. In the case of Low Tension Industrial Consumers, the tariff was increased from 14.5 ps per unit to 24.5 ps per unit in 1980 an·d maintained at the _c;_ rate of 24.5 ps per unit in 1982. In the case of Low Tension Commercial Consumers, the tariff was increased from 38 ps per unit to 66 ps per unit in 1980 but brought down again considerably in 1982 to 50. 70 ps per unit. The very circumstance that the tariff was either brought down or maintained at the same level in 1982 when compared with the 1980 tariff appears to be an indication that the increase in· !980 was H A B c D E F _(;_ ll 658 SUPREME COURT REPORTS [19861 3 S.C.R. thought by the Board itself to be rather steep. We have already noticed that· 1980-81 and 1981-82 were the years when the accounts of the Electricity Board recorded a net surplus after meeting all expenses including interest charges. In the circumstances, we think that it is desirable that the Board may re-consider the 1980 tariff for Low Tension Commercial and Low Tension Industrial Consumers. Shri Potti submitted that the 1980 Committee took place consideration the anticipated augmentation of the generating capacity from - the proposed new power stations of Idukki, Saharigiri and ldamalyar, whereas these projects were not commissioned till 1984 and thus the cost-structure arrived at by the Committee was vitiated. We· do not think so. From the figures supplied to us we find that notwithstanding the failure to commission the new projects, there was no shortfall in the production of energy. A large part of expenditure involved in the setting up .of the new projects had to be met in the several years preceding the actual commissioning of the projects. Therefore, it is not correct .to say that the cost structure arrived at by the Committee was in anx way affected by the non-commissioning of 'the new projects between 1980 and 1982. Another submission made by Sbri Potti was that the Committee erred in not taking into account the financial position of the Board as brought out by the year 1978-79 which showed that the Board had already turned the corner and that there was therefore no need for enhancing the rates. This submission is again without substance. As we mentioned earlier, the rise in revenue receipts in the year 1978-79 due to the unprecedented sale of energy to neighbouring states, a special situation which was the result of peculiar circumstances which prevailed that year and continued to prevail for a few years thereafter. The sale of energy to neighbouring States was not to be taken as a permanent phenomenon to every year. Yet another submission of Shri Potti was that the 1980 Committee having taken as the basis the 1982 projected cost so as to maintain price stability for a period of five years, it was not proper to revise the tariff again in 1982. But we find that the actual cost of producing energy in 198)-82 and 1982-83 had risen much above the projected 1982 cost and therefore the 1982 Committee has no option but to again consider further revision of the tariff. We are not delving into more details as we are satisfied that it is not within our province to examine the price structure in minute detail if we are satisfied that the revision of tariff is not arbitrary and is not .the result of the application of any wrong principle. Relying upon the observation, "It would have been manifestly unjust and discriminatory that one consumer should benefit at _>-_ ' KER. STATE E.B. _v._ PRABHU [REDDY, J.[ 659 the cost of other consumers or general tax payers;" made in _D.C. M._ v. _Rajasthan State Electricity Board,_ [1986] 2 SCC 431 it was argued by Shri Potti that it was not open to the Board to give favoured treatment to Low Tension Domestic and Agricultural Consumers at the cost of the rest of the consumers. We do not find any force in this submission. Section 49 (3) expressly reserves the power of the Board, - if it cc;msiders it necessary or expedient, to fix different tariff for the supply of electricity to any person having regard to the geographical position of any area, the nature of the supply and purpose for which supply is required and other relevant factor. Different tariffs for High and Low Tension Consumers and for different classes of consumers, such as, Industrial, Commercial, Agricultural and Domestic have been prescribed and the differention appears to us to be reasonable and far from arbitrary and to be based on intelligent and intelligible criteria. In the result, we allow the appeals filed by the Ketala State Electricity Board, set aside the judgments of the High Court, uphold the validity of the notifications revising the tariffs and dismiss the writ petitions filed in the High Court, subject to direction that the Kerala State Electricity Board will reconsider the revised tariff introduced in 1980 in regard to Low Tension Industrial and Low Tension Commercial Consumers only, with liberty to fix separate rates, if necessary for the years 1980 and 1981. This direction will not affect the 1982 and 1984 tariff revisions. There-will be no order regarding costs. A.P.J. Appeals allowed. A B c D E
