Holding

A tariff order cannot be amended during the ‘truing up’ exercise; any such amendment is impermissible and the DERC’s altered findings are set aside, with the appellants entitled to recover interest on consumer security deposits and to have enforcement sales treated as supply.

Summary

BSES Rajdhani Power Ltd. and BSES Yamuna Power Ltd., distribution licensees in Delhi, challenged the Delhi Electricity Regulatory Commission’s (DERC) tariff orders that altered the methodology for computing AT&C losses, depreciation, FR/SR salaries, fringe benefit tax, and interest on consumer security deposits during the ‘truing up’ exercise for FY 2008‑09, 2009‑10 and ARR for FY 2011‑12. The appellants argued that the regulator cannot amend a tariff order after it has become final, as this would amount to a retrospective revision prohibited by Sections 62 and 64 of the Electricity Act, 2003. The Supreme Court held that a tariff order is quasi‑judicial and may be amended only under Section 64(6) within its period of applicability; the ‘truing up’ stage is not a licence to change the original methodology. Consequently, the Court set aside DERC’s findings that altered the original tariff order, directed DERC to allow interest on consumer security deposits, and to treat assessed energy in enforcement sales as actual supply. The appeals were allowed.

Issues considered

  • Whether the DERC can amend a tariff order during the ‘truing up’ exercise by changing the methodology for AT&C losses, depreciation, FR/SR salaries, fringe benefit tax, and interest on consumer security deposits.
  • Whether such amendment amounts to a retrospective revision prohibited under Section 64(6) of the Electricity Act, 2003.
  • Whether the interest on consumer security deposits retained by DPCL is a recoverable expense under Section 47(4) of the Electricity Act, 2003.
  • Whether energy assessed in enforcement sales under Section 126 of the Electricity Act, 2003 should be treated as actual supply for tariff purposes.

           [S. ABDUL NAZEER AND KRISHNA MURARI, JJ.]
             Electricity Act, 2003 : ss. 2(17), 12, 14, 43, 61, 62 and 64 –
      Determination of tariff – Exercise of ‘truing up’ – Appellants are
      distribution licensees, involved in distributing and supplying
C
      electricity in their designated areas within the NCT of Delhi – In
      terms of the 2003 Act, Delhi Electricity Regulatory Commission-
      DERC, regulated the Annual revenue requirement-ARR of the
      appellants to conduct the licensed business and consequently the
      tariff to be recovered from the consumers – DERC made
D     disallowances in Tariff orders dated 26.08.2012 for determination
      of ARR and Tariff for FY 2011-12 and truing up of financials for
      FY 2008-09 and FY 2009-10 – DERC changed methodology of
      computation of ARR at the stage of true up – Challenged by the
      appellants before the appellate tribunal for Electricity – Appellants
      contented that since privatization, the ARR determined by the DERC
E
      was not even sufficient to meet the actual power purchase cost which
      led to creation of a huge revenue gap; that the DERC in repeated
      disregard to its statutory regulations and its own statutory advice
      refused to make periodic increase in the tariff rate, leading to the
      indebtness of appellants – Findings of DERC confirmed by APTEL
F     – On appeal, held: It is not permissible to amend the tariff order
      during true up exercise – On the pretext of prudence check and
      truing up, DERC could not have amended the tariff order –
      Regulator cannot ‘change the rules after it has begun’ in the ‘truing
      up exercise’ – Thus, the findings of the DERC, as confirmed by the
      APTEL in the on issues pertaining to change in methodology in
G
      computation of AT&C losses; change in methodology for
      computation of depreciation; disallowance of salary for FR/SR
      Structure; and disallowance of Fringe Benefit Tax, are contrary to
      the order of the original MYT determination Tariff Order dated
      23.02.2008 and 28.05.2009, thus, set aside – As regards the

not an opportunity for the DERC to rethink de novo on the basic          D
principles, premises and issues involved in the initial projections of
the revenue requirement of the licensee – ‘Truing up’ exercise cannot
be done to retrospectively change the methodology/principles of
tariff determination and re- opening the original tariff determination
order thereby setting the tariff determination process to a naught at
‘true-up’ stage – Revision or re-determination of the tariff already     E
determined by DERC on the pretext of prudence check and truing
up would amount to amendment of the tariff order, which can be
done only as per the provisions of sub-Section (6) of s.64 within the
period for which the Tariff Order was applicable – DERC cannot
amend the tariff order for the period 01.04.2008 to 31.03.2010 in        F
the guise of ‘true-up’ after the relevant financial year is over and
the same is replaced by a subsequent tariff Order – This would
amount to a retrospective revision of tariff when the relevant period
for such tariff order is already over – Thus, not permissible to amend
the tariff order made u/s. 64 during the ‘truing up’ exercise.

A           ‘Truing up’ – Meaning of – Held: ‘Truing up’ is the adjustment
      of actual amounts incurred by the licensee against the estimated/
      projected amounts determined under the Annual revenue
      requirement-ARR.
            ‘Substantial Question of Law’ – Meaning of – Discussed.
B           ‘Appeal’ – Meaning – Discussed.
            Allowing the appeals, the Court
             HELD: 1.1 An appeal to this Court under Section 125 could
      be filed on the grounds specified in Section 100 of the CPC. Under
C     Section 100 of the CPC, an appeal could be filed only when the
      case involves ‘a substantial question of law’, as may be framed
      by the appellate court. Thus, the existence of a ‘substantial
      question of law’ arising from the judgment of the APTEL is sine
      qua non for exercise of jurisdiction by this Court under Section
      125 of the 2003 Act. [Para 27][807-H; 808-A-B]
D
              1.2. A tariff order is quasi•judicial in nature which becomes
      final and binding on the parties unless it is amended or revoked
      under Section 64(6) or set aside by the Appellate Authority. Apart
      from this, at the stage of ‘truing up’, the DERC cannot change
      the rules/methodology used in the initial tariff determination by
E     changing the basic principles, premises and issues involved in
      the initial projection of ARR. [Para 51][816-C-D]
             1.3. ‘Truing up’ means the adjustment of actual amounts
      incurred by the Licensee against the estimated/projected amounts
      determined under the ARR. ‘Truing up’ stage is not an opportunity
F     for the DERC to rethink de novo on the basic principles, premises
      and issues involved in the initial projections of the revenue
      requirement of the licensee. ‘Truing up’ exercise cannot be done
      to retrospectively change the methodology/principles of tariff
      determination and re•opening the original tariff determination
      order thereby setting the tariff determination process to a naught
G
      at ‘trueup’ stage. [Para 52, 53][816-D-E; 817-B-C]
           1.4 Revision or re-determination of the tariff already
      determined by DERC on the pretext of prudence check and truing
      up would amount to amendment of the tariff order, which can be

done only as per the provisions of sub•Section (6) of Section 64       A
of the 2003 Act within the period for which the Tariff Order was
applicable. DERC cannot amend the tariff order for the period
01.04.2008 to 31.03.2010 in the guise of ‘true-up’ after the
relevant financial year is over and the same is replaced by a
subsequent tariff Order. This would amount to a retrospective
                                                                       B
revision of tariff when the relevant period for such tariff order is
already over. Therefore, it is not permissible to amend the tariff
order made under Section 64 of the 2003 Act during the ‘truing
up’ exercise. [Para 55][817-E-G]
       1.5 In the original MYT determination (Tariff Order dated
28.05.2009), the DERC took into account the full late payment          C
surcharge (‘LPSC’) revenue as also the DVB arrears while
computing the targets of Collection Efficiency. However, while
truing up for the year in question, the DERC has retrospectively
sought to take away part of the LPSC revenue by deducting the
Financing Cost on LPSC in comparing the actual Collection              D
Efficiency with the projected Collection Efficiency. Hence,allowing
the Financing Costs on LPSC revenue and then deducting it from
the LPSC revenue would tantamount to giving by one hand and
taking it away by the other. This order of the DERC is contrary
to the original MYT determination. [Para 57, 58][818-A-B; 819-
E-F]                                                                   E

       1.6 In the Original Determination Order dated 28.05.2009
(F.Y. 2008-09), DERC has allowed depreciation on the assets
funded by consumer contributions. However, DERC changed the
methodology of computation of ARR at the stage of true up.
According to the learned counsel for the respondent, DERC had          F
inadvertently made an error and adopted an approach contrary
to the mandate of 2007 MYT Regulations while computing the
depreciation when originally issuing the tariff order, which was
rectified in the true up exercise. However, learned counsel for
the appellants submit that no error has been committed by the          G
DERC in the tariff order dated 28.05.2009 and it is only after
considering the relevant MYT Regulations that depreciation to
the appellants on the assets that were funded by consumer
contributions was allowed. Perusal of the Tariff Order dated
28.05.2009 would clearly indicate that after considering the
                                                                       H
794           SUPREME COURT REPORTS                     [2022] 14 S.C.R.


A     contentions of the parties the aforesaid depreciation has been
      allowed. The Court has already held that it is not permissible to
      amend the tariff order during true up exercise. On the pretext of
      prudence check and truing up, DERC could not have amended
      the tariff order. [Paras 59, 60][819-F-H; 820-A-B]
B           1.7. During projection of expenses for the entire control
      period, the Tariff Order dated 23.02.2008 had projected employee
      expenses considering inter alia the impact of the anticipated Sixth
      Central Pay Commission Report. However, contrary to its own
      undertaking, the DERC in Tariff Order dated 26.08.2011 has
      erroneously changed its own methodology at the stage of truing
C     up, by not allowing employee expenses of FR/SR employees as
      per actuals. The DERC, at the stage of truing up, has changed
      the methodology and disallowed the actual salary of FR&SR
      employees, which is impermissible. The DERC in the Tariff Order
      dated 26.08.2011 has acted contrary to its own undertaking of
D     truing up the impact of employee expenses on account of the
      Sixth Central Pay Commission Report. [Paras 61,63][820-B-C;
      822-F-H]
             1.8 As regards the issue is in relation to disallowance of
      fringe benefit tax, the DERC has allowed fringe benefit tax in the
E     MYT Order dated 23.02.2008. The DERC, at the stage of truing
      up for the F.Y. 2008•09, has changed the methodology and
      disallowed the fringe benefit tax incurred by the appellants. DERC
      cannot re•open the basis of determination of tariff at the stage of
      ‘truing up’. Revision or redetermination of the tariff already
      determined by the DERC on the pretext of prudence check and
F     truing up would amount to amendment of tariff order, which is
      not permissible in law. Truing up stage is not an opportunity for
      DERC to re•think de novo the basic principles, premises and
      issues involved in the initial projection of the revenue
      requirements of the licensee. Therefore, the findings of the
G     DERC, as confirmed by the APTEL in the impugned order, on
      issue nos. 1, 2, 3 and 5 are contrary to the order of the original
      MYT determination (Tariff Order(s) dated 23.02.2008 and
      28.05.2009) which are accordingly set aside. [Paras 64-67][823-

       1.9. As regards disallowance of interest incurred on            A
Consumers Security Deposit retained by Delhi Power Company
Limited (‘DPCL’), the DERC in the tariff order dated 26.08.2011
has disallowed the interest on Consumers Security Deposit paid
for pre•privatization period received by DVB, which is yet to be
transferred to the appellants. The APTEL has confirmed this order
                                                                       B
of the DERC. At the time of unbundling of the erstwhile DVB
(w.e.f. 01.07.2022), the quantum of Consumers Security Deposit
reflected in the opening balance sheet notified in terms of
statutory transfer scheme, was not transferred by the DPCL (the
Holding Company wholly owned by the Government of NCT of
Delhi) to the appellants and other successor private Discoms.          C
The appellants being distribution licensees under the 2003 Act
are required to and are continuing to pay interest on the said
Consumers Security Deposit in terms of Section 47(4) of the 2003
Act even though the principal sum was never transferred to them
in its entirety by DPCL. The DERC by its order dated 23.04.2007
                                                                       D
has held that it does not have power to issue any directions to
DPCL. [Para 68, 69][823-G-H; 824-A-C]
       1.10. Disallowing interest paid by the appellants towards
Consumers Security Deposit held by DPCL in the ARR of the
appellants is wholly misconstrued. Interest on consumers’ deposit
which is being paid by the appellants is a legitimate expense. It      E
is not in dispute that the security deposit was not transferred by
the DPCL to the appellants. However, the appellants were
required to bear the costs of the same. In case, the principal sum
on Consumers Security Deposit held by DPCL is transferred to
the appellants with interest, the appellants would, subject to their   F
legitimate expenditures, retain such interest and benefit of any
balance of excess interest received by the appellants would be
passed on to the consumers in tariff. Therefore, there is no merit
in the contention of the learned counsel for the respondent that
if the interest burden is passed on to the consumers presently,
the appellants would, in effect, receive a double benefit in case      G
they succeed in the writ petition pending before the High Court.
Therefore, the appellants are entitled to recover interest on
Consumers Security Deposit as held by the DPCL. The DERC is
directed to allow the interest on Consumers Security Deposit
                                                                       H
796            SUPREME COURT REPORTS                     [2022] 14 S.C.R.


A     held by the DPCL and impact thereof to the appellants. The
      findings of the DERC and the APTEL in this regard are set aside.
      [Paras 71,72][824-E-H; 825-A-B]
             1.11. As regards, the issue of enforcement sales i.e. sales
      which are deemed to have been occurred in cases of electricity
B     theft, the question arose whether the impugned findings in the
      order of the APTEL are against the legal principle that when the
      statute creates a legal fiction i.e. energy assessed is ‘deemed’ to
      be consumed, the same has to be given effect to with all its
      consequences i.e. same quantum of energy is to be accounted
      for as supplied. [Para 73][825-B-C]
C
            1.12 Electricity transmitted may be stolen or used
      unauthorizedly. While theft/unauthorized use was approximately
      60% before privatization, it has now been brought down to 7 to
      8%. Unauthorized use and theft are dealt with in Section 126 of
      the 2003 Act. The Vigilance/Enforcement Department detects
D     theft/unauthorized use of electricity. After giving due opportunity,
      the bills are generated for electricity stolen/unauthorized
      use.These are called enforcement sales/assessed sales. The
      statutory charge for such theft/unauthorized use is twice the
      normal rate. While settling enforcement cases of small consumers,
E     Lok Adalats often provide discounts to errant consumers on the
      assessed equivalent of the rupee amount and not on the assessed
      units of energy. The assessment of units of energy as deemed to
      be sales to the consumers is in accordance with Section 126 of
      the 2003 Act read with provisions for such assessment specified
      by the DERC itself. [Para 74-76][825-C-D; 826-A-C]
F
            1.13. The methodology adopted by the DERC is contrary
      to the settled principle of law that when the law deems a certain
      imaginary state of affairs as real, DERC would not let its
      imagination boggle at treating the 100 units as sales. Such
      imaginary state of affairs must be taken to its logical end and
G     commend the treatment of 100 units as ‘sales’. The assessed
      energy has to be considered as supply by the appellants in
      enforcement cases. Therefore, the DERC to consider assessed
      energy for calculation of enforcement sales and allow the impact
      of the same along with carrying costs. [Para 79, 80][827-C-E]

            The Judgment of the Court was delivered by
C           S. ABDUL NAZEER, J.
             1. These two appeals have been filed by BSES Rajdhani Power
      Ltd. (C.A. No.4324 of 2015) and BSES Yamuna Power Ltd. (C.A.
      No.4323 of 2015) (hereinafter referred to as ‘Appellants’) challenging
      certain findings of the Appellate Tribunal for Electricity, New Delhi
D     (‘APTEL’) in the common judgment and order dated 28.11.2014
      (‘Impugned Order’) passed in Appeal Nos.61 and 62 of 2012 (‘Tariff
      Appeals’). The Tariff Appeals were filed by the appellants before the
      APTEL challenging certain findings of the Delhi Electricity Regulatory
      Commission (‘DERC’) in the Tariff Order dated 26.08.2012 for Truing
E     Up of financials for FY 2008-09 and FY 2009-10 and Aggregate Revenue
      Requirement (‘ARR’) for FY 2011-12. DERC has also filed appeals
      (C.A. Nos.8660-61 of 2015) challenging certain findings in the common
      impugned order and the said appeals will be heard and decided separately.
             2. The Appellants are Distribution Licensees (“Discoms”) in terms
F     of Section 2(17) of the Electricity Act, 2003 (‘2003 Act’). The primary
      function of a Discom is to give supply to any premises upon an application
      being made by a consumer in compliance with the applicable laws,
      including paying requisite charges, except where prevented by force
      majeure conditions like cyclones or floods.
             3. The Appellants purchase 90% to 95% of the power from Central
G
      and State Generating Companies. Tariff of Central Generating Stations
      is determined by the Central Electricity Regulatory Commission (‘CERC’)
      and, therefore, the Appellants have no control over the tariff to be paid
      to the Central Generating Stations. Simultaneously, the tariff for the State
      Generating Companies is determined by the State Regulator i.e. DERC.

    REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

       4. It is the case of the Appellants that since privatization, the ARR   A
determined by the DERC was not even sufficient to meet the actual
power purchase cost which has led to creation of a huge revenue gap. It
is also contended that the DERC in repeated disregard to its statutory
regulations and its own statutory advice has refused to make periodic
increase in the tariff rate. The actions of the DERC have resulted in a
                                                                               B
situation where the Appellants are deeply indebted and have been forced
to borrow/take loans to fund their day-to-day operations which, in turn,
have also dried up leaving the Appellants without adequate monies to
pay their suppliers.
      5. The Appellants have challenged the finding of the APTEL in
the Impugned Order on the following issues:                                    C

      A.     Change in methodology in computation of Aggregate
             Technical and Commercial (AT&C) losses [Issue 14 in
             Impugned Order]
      B.     Change in methodology for computation of Depreciation             D
             [Issue 15 in Impugned Order]
      C.     Disallowance of salary for Fundamental Rules and
             Supplementary Rules (FR/SR) structure [Issue 23 in
             Impugned order]
      D.     Disallowance of interest accrued on Consumer Security             E
             Deposit retained by Delhi Power Corporation Limited
             (DPCL) [Issue 29 in Impugned Order]
      E.     Disallowance of Fringe Benefit Tax [Issue 34 in Impugned
             Order]
                                                                               F
      F.     Reduction in Million Units (MUs) in relation to Enforcement
             sale for the purpose of calculation of AT&C Loss [Issue 14
             in Impugned Order]
       6. It is to be noticed that the above-mentioned Issue ‘C’ has been
challenged only by BSES Rajdhani Power Ltd. in C.A. No.4324 of 2015
while the remaining issues have been challenged by both BSES Rajdhani          G
Power Ltd. and BSES Yamuna Power Ltd. and are subject-matter of
C.A. No.4324 of 2015 and C.A.No. 4323 of 2015.
      7. The Tariff Appeals were filed by the Appellants challenging
the disallowances in their respective Tariff Orders dated 26.08.2012
passed by the DERC for:                                                        H
800             SUPREME COURT REPORTS                          [2022] 14 S.C.R.


A               (a) Determination of ARR and Tariff for FY 2011-12; and
                (b) Truing up of financials for FY 2008-09 and FY 2009-10.
             8. According to the appellants, the present Civil Appeals give rise
      to substantial questions of law under Section 125 of the 2003 Act on six
      issues. It is contended that the said substantial questions of law have
B     arisen primarily because the DERC has, inter alia, deliberately refused
      to follow statutory regulations while truing up. Further, it is contended
      that APTEL’s Impugned Order has failed to note the illegal manner of
      truing up followed by DERC and, more importantly, APTEL has failed
      to follow its own rulings in previous cases.
C            9. However, the respondents have contended that the appellants
      have entirely failed to establish the existence of any substantial question
      of law as required under Section 125 of the 2003 Act, read with Section
      100 of the Code of Civil Procedure, 1908 (‘CPC’) on any of the above
      issues.
D             10. Before considering the detailed submissions on each of the
      above issues, it is necessary to provide an overview of the current and
      historical legal framework of electricity laws in India, including the tariff
      determination process, and the role and powers of the DERC in the
      tariff determination process.
E            11. Prior to independence, the Indian Electricity Act, 1910 (‘1910
      Act’) governed the supply and use of electrical energy in India. Part-II
      of the 1910 Act was related to supply of electricity and contained
      provisions concerning:
                (a) Grant of license for supply of electricity by the State
F               Government in consultation with the State Electricity Boards
                (“SEB”) and
                (b) Obligation and rights of licensees, consumers, etc. along
                with other modalities.
             Part-III of the 1910 Act dealt with Supply, Transmission and Use
G     of Energy by Non-licensees. Part-IV of the 1910 Act provided for
      constitution, duties of advisory boards at the State and Central levels
      along with other authorities such as electrical inspectors and Central
      Electricity Board (“CEB”). CEB, under Section 37 of the 1910 Act, was
      empowered to make rules to regulate the generation, transmission, supply,
H     and use of energy.

     REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

       12. On 10.09.1948, the Electricity (Supply) Act, 1948 (“Supply           A
Act, 1948”) was notified to provide for: (a) the rationalization of the
production and supply of electricity, (b) taking of measures conducive to
electrical development; and (c) all matters incidental to the above. The
Supply Act, 1948 was a more detailed and comprehensive code and
provided for establishment of SEBs to control generation, distribution,
                                                                                B
and utilization of electricity within their respective states and the Central
Electricity Authority (‘CEA’) for planning and development of the national
power system.
        13. On 02.07.1998, the Electricity Regulatory Commissions Act,
1998 (‘Commissions Act, 1998’) was notified with effect from 25.04.1998
as an Act to provide for the establishment of a Central Electricity             C
Regulatory Commission (“CERC”) and State Electricity Regulatory
Commission (“SERC”), for rationalization of electricity tariff, transparent
policies regarding subsidies, promotion of efficient and environmentally
benign policies and other matters connected therewith or incidental
thereto. Chapter-VI of the Commissions Act, 1998 was related to energy          D
tariff and provided for the determination of tariff by Central and State
Commissions.
      14. Insofar as the National Capital Territory (“NCT”) of Delhi is
concerned, on 08.03.2001, the Delhi Electricity Reforms Act, 2000
(“Reforms Act, 2000”) was notified to:                                          E
      (a) provide re-structuring of the electricity industry (unbundling
      of generation, transmission, and distribution),
      (b) increasing avenues for participation of private sector in the
      electricity industry; and
                                                                                F
      (c) generally, for taking measures conducive to the development
      and management of the electricity industry in an efficient,
      commercial, economic, and competitive manner in the NCT of
      Delhi and for matters connected therewith or incidental thereto.
        15. With effect from 01.07.2002, pursuant to the unbundling,
                                                                                G
restructuring and reform of the erstwhile Delhi Vidyut Board (“DVB”)
and privatization of distribution of electricity, the appellants succeeded
to the respective Distribution Undertakings and Business in their area of
supply. The appellants have been granted Distribution and Retail Supply
License by DERC to undertake distribution (wheeling) and retail supply
of electricity in their respective areas of supply in the NCT of Delhi.         H
802             SUPREME COURT REPORTS                           [2022] 14 S.C.R.


A     From 01.07.2002 till 31.03.2007, the Delhi Transco Ltd. (“DTL”) was
      entrusted with the responsibility of bulk procurement and bulk supply of
      power in the NCT of Delhi.
            16. In the year 2003, the Parliament repealed the previous three
      laws viz., the 1910 Act, the Supply Act, 1948 and the Commissions Act,
B     1998, and enacted a comprehensive consolidated law called the Electricity
      Act, 2003. The objectives of the Act are:-
            (a) to consolidate the laws relating to generation, transmission,
            distribution, trading and use of electricity,
            (b) taking measures conducive to development of electricity
C           industry, promoting competition therein, protecting interest of
            consumers and supply of electricity to all areas,
            (c) rationalization of electricity tariff, ensuring transparent policies
            regarding subsidies, promotion of efficient and environmentally
            benign policies,
D
            (d) constitution of the CEA, Electricity Regulatory Commissions,
            and establishment of an Appellate Tribunal and for matters
            connected therewith or incidental thereto.
              17. The scheme of the 2003 Act is predicated on consolidating all
      laws governing electricity and repealing the existing laws. The legislative
E
      policy of distancing the Government from the tariff determination was
      carried forward in the 2003 Act. The intent and purpose of the 2003 Act
      is to liberalize the electricity sector and to ensure that the distribution
      and supply of electricity is conducted on commercial principles. The
      legislature intended to promote factors that encourage and reward
F     efficiency, competition, economical use of resources and optimum
      investments and safeguard the interest of the consumers vis-à-vis
      recovery of cost of electricity in a reasonable manner as envisaged under
      Section 61 of the 2003 Act.
             18. Being regulated licensees responsible for distribution and retail
G     supply of electricity in their designated areas within the NCT of Delhi in
      terms of Section 12 of 2003 Act, the annual revenue requirement of the
      Appellants to conduct the licensed business and consequently the tariff
      to be recovered from the consumers, is regulated by the DERC, being
      the State Electricity Regulatory Commission. DERC is vested with a
      substantial set of divergent powers – legislative, executive, adjudicatory
H
    BSES RAJDHANI POWER LTD. v. DELHI ELECTRICITY                                803
     REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

and advisory – each being distinctly defined and governed by law. One            A
of the critical issues arising in these Civil Appeals relates to sanctity of
each such function and their interplay. In this regard, it is noteworthy
that Section 3 of the 2003 Act provides as under:
       “Section 3. National Electricity Policy and Plan. -
       (1) The Central Government shall, from time to time, prepare the          B
       National Electricity Policy and tariff policy, in consultation with
       the State Governments and the Authority for development of the
       power system based on optimal utilisation of resources such as
       coal, natural gas, nuclear substances or materials, hydro and
       renewable sources of energy.                                              C
       (2) The Central Government shall publish National electricity Policy
       and tariff policy from time to time.
       (3) The Central Government may, from time to time in consultation
       with the State Governments, and the Authority review or revise
       the National Electricity Policy and tariff policy referred to in sub-     D
       section (1).
       (4) The Authority shall prepare a National Electricity Plan in
       accordance with the National Electricity Policy and notify such
       plan once in five years.
                                                                                 E
       Provided            xxx               xxx               xxx
       (5) The Authority may review or revise the National Electricity
       Plan in accordance with the National Electricity Policy.”
        19. Section 14 of the 2003 Act provides for grant of licences on
application made under Section 15 of the Act - (a) to transmit electricity       F
as a transmission licensee; or (b) to distribute electricity as a distribution
licensee; or (c) to undertake trading in electricity as an electricity trader,
in any area which may be specified in the licence.
      20. Section 43 of the 2003 Act provides for the universal supply
obligation of the Discoms, which is as under:                                    G
       “43. Duty to supply on request –
       (1) Save as otherwise provided in this Act, every distribution
       licensee, shall, on an application by the owner or occupier of any
       premises, give supply of electricity to such premises, within one
       month after receipt of the application requiring such supply.             H

             21. Section 61 of the 2003 Act lays down the guiding principles
      for tariff which are as under:
B           “61. Tariff regulations.- The Appropriate Commission shall, subject
            to the provisions of this Act, specify the terms and conditions for
            the determination of tariff, and in doing so, shall be guided by the
            following, namely:-
            (a)     the principles and methodologies specified by the Central
C                   Commission for determination of the tariff applicable to
                    generating companies and transmission licensees;
            (b)     the generation, transmission, distribution and supply of
                    electricity are conducted on commercial principles;
            (c)     the factors which would encourage competition, efficiency,
D                   economical use of the resources, good performance and
                    optimum investments;
            (d)     safeguarding of consumers’ interest and at the same time,
                    recovery of the cost of electricity in a reasonable manner;
            (e)     the principles rewarding efficiency in performance;
E
            (f)     multi-year tariff principles;
            (g)     that the tariff progressively reflects the cost of supply of
                    electricity and also, reduces cross-subsidies in the manner
                    specified by the Appropriate Commission;
F           (h)     the promotion of co-generation and generation of electricity
                    from renewable sources of energy;
            (i)     the National Electricity Policy and tariff policy:
            Provided that the terms and conditions for determination of tariff
            under the Electricity (Supply) Act, 1948, the Electricity Regulatory

            Commission Act, 1998 and the enactments specified in the
            Schedule as they stood immediately before the appointed date,
            shall continue to apply for a period of one year or until the terms
            and conditions for tariff are specified under this section, whichever
            is earlier.”

    REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

       22. Sections 62 and 64 of the 2003 Act lay down the procedure           A
for determination of tariff for, inter alia, wheeling and retail sale of
electricity as under:
      “62. Determination of tariff.-
      (1) The Appropriate Commission shall determine the tariff in
      accordance with the provisions of this Act for –                         B

      (a)    supply of electricity by a generating company to a distribution
             licensee:
             Provided that the Appropriate Commission may, in case of
             shortage of supply of electricity, fix the minimum and            C
             maximum ceiling of tariff for sale or purchase of electricity
             in pursuance of an agreement, entered into between a
             generating company and a licensee or between licensees,
             for a period not exceeding one year to ensure reasonable
             prices of electricity;
                                                                               D
      (b)    transmission of electricity;
      (c)    wheeling of electricity;
      (d)    retail sale of electricity:
      Provided that in case of distribution of electricity in the same area
      by two or more distribution licensees, the Appropriate Commission        E
      may, for promoting competition among distribution licensees, fix
      only maximum ceiling of tariff for retail sale of electricity.
      (2) The Appropriate Commission may require a licensee or a
      generating company to furnish separate details, as may be specified
      in respect of generation, transmission and distribution for              F
      determination of tariff.
      (3) The Appropriate Commission shall not, while determining the
      tariff under this Act, show undue preference to any consumer of
      electricity but may differentiate according to the consumer’s load
      factor, power factor, voltage, total consumption of electricity during   G
      any specified period or the time at which the supply is required or
      the geographical position of any area, the nature of supply and the
      purpose for which the supply is required.
      (4) No tariff or part of any tariff may ordinarily be amended,
      more frequently than once in any financial year, except in respect       H

A     of any changes expressly permitted under the terms of any fuel
      surcharge formula as may be specified. The Electricity Act, 2003.
      (5) The Commission may require a licensee or a generating
      company to comply with such procedures as may be specified for
      calculating the expected revenues from the tariff and charges
B     which he or it is permitted to recover.
      (6) If any licensee or a generating company recovers a price or
      charge exceeding the tariff determined under this section, the
      excess amount shall be recoverable by the person who has paid
      such price or charge along with interest equivalent to the bank
C     rate without prejudice to any other liability incurred by the
      licensee.”
      “64. Procedure for tariff order.-
      (1) An application for determination of tariff under section 62
      shall be made by a generating company or licensee in such manner
D     and accompanied by such fee, as may be determined by regulations.
      (2) Every applicant shall publish the application, in such abridged
      form and manner, as may be specified by the Appropriate
      Commission.
      (3) The Appropriate Commission shall, within one hundred and
E     twenty days from receipt of an application under sub-section (1)

      (5) Notwithstanding anything contained in Part X, the tariff for       A
      any inter-State supply, transmission or wheeling of electricity, as
      the case may be, involving the territories of two States may, upon
      application made to it by the parties intending to undertake such
      supply, transmission or wheeling, be determined under this section
      by the State Commission having jurisdiction in respect of the
                                                                             B
      licensee who intends to distribute electricity and make payment
      therefor.
      (6) A tariff order shall, unless amended or revoked, continue to be
      in force for such period as may be specified in the tariff order.”
      23. ARR of the Appellants, and consequently the tariff to be           C
recovered from the consumers, is regulated by the DERC, and determined
under Section 62 read with Section 61 of the 2003 Act.
       24. Section 86 of the 2003 Act lays down the functions of the
State Commissions i.e. DERC in this case, and the rule-making power
of the Central Government is set out in Section 176 thereof.                 D
      25. Before considering the other questions, let us consider the
preliminary objection raised by learned counsel for the respondent-DERC
as to whether the appeals involve any substantial question of law as
required under Section 125 of the 2003 Act read with Section 100 of the
CPC?                                                                         E
      26. Section 125 of the 2003 Act provides for an appeal to this
Court against the decision or order of the APTEL which reads as under:
      “125. Appeal to Supreme Court.-
      Any person aggrieved by any decision or order of the Appellate
                                                                             F
      Tribunal, may, file an appeal to the Supreme Court within sixty
      days from the date of communication of the decision or order of
      the Appellate Tribunal, to him, on any one or more of the grounds
      specified in section 100 of the Code of Civil Procedure,1908 (5 of
      1908):
      Provided that the Supreme Court may, if it is satisfied that the       G
      appellant was prevented by sufficient cause from filing the appeal
      within the said period, allow it to be filed within a further period
      not exceeding sixty days.”
       27. Thus, an appeal to this Court under Section 125 could be filed
on the grounds specified in Section 100 of the CPC. Under Section 100        H
808                SUPREME COURT REPORTS                          [2022] 14 S.C.R.


A     of the CPC, an appeal could be filed only when the case involves ‘a
      substantial question of law’, as may be framed by the appellate court.
      Thus, the existence of a ‘substantial question of law’ arising from the
      judgment of the APTEL is sine qua non for exercise of jurisdiction by
      this Court under Section 125 of the 2003 Act.
B            28. The expression ‘appeal’ has not been defined in the CPC.
      Black’s Law Dictionary (10th Edn.) defines an ‘appeal’ as “a proceeding
      undertaken to have a decision reconsidered by bringing it to a higher
      authority.” An appeal is judicial examination of a decision of a subordinate
      court by a higher court to rectify any possible error(s) in the order under
      appeal. The law provides the remedy of an appeal in recognition of the
C     fact that those manning the judicial tiers too may commit errors.
            29. The test to determine whether a question is a substantial
      question of law or not was laid down by a Constitution Bench of this
      Court in Sir Chunilal V. Mehta & Sons Ltd. v. The Century Spg. &
      Mfg. Co. Ltd.1 as under : (AIR p. 1318, para 6)
D
               “6. … The proper test for determining whether a question of law
               raised in the case is substantial would, in our opinion, be whether
               it is of general public importance or whether it directly and
               substantially affects the rights of the parties and if so whether it is
               either an open question in the sense that it is not finally settled by
E              this Court or by the Privy Council or by the Federal Court or is not
               free from difficulty or calls for discussion of alternative views. If
               the question is settled by the highest court or the general principles
               to be applied in determining the question are well settled and there
               is a mere question of applying those principles or that the plea
F              raised is palpably absurd the question would not be a substantial
               question of law.”
             30. Thus, the word ‘substantial’ as qualifying ‘question of law’
      means, of having substance, essential, real, of sound worth, important or
      considerable. It is to be understood as something in contradistinction
G     with technical, of no substance or consequence, or academic. For
      determining whether a case involves substantial question of law, the test
      is not merely the importance of the question, but its importance to the
      case itself necessitating the decision of the question. The appropriate
      test for determining whether the question of law raised in the case is
      1
H         1962 Supp (3) SCR 549 : AIR 1962 SC 1314
    BSES RAJDHANI POWER LTD. v. DELHI ELECTRICITY                                  809
     REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

substantial would be to see whether it directly and substantially affects          A
the rights of the parties. If it is established that the decision is contrary to
law or the decision has failed to determine some material issue of law or
if there is substantial error or defect in the decision of the case on merits,
the court can interfere with the conclusion of the lower court or tribunal.
The stakes involved in the case are immaterial as long as the impact or
                                                                                   B
effect of the question of law has a bearing on the lis between the parties.
       31. Thus, in a second appeal, the appellant is entitled to point out
that the order impugned is bad in law because it is de hors the pleadings,
or it was based on no evidence or it was based on misreading of material
documentary evidence or it was recorded against the provision of law or
the decision is one which no Judge acting judicially could reasonably              C
have reached. Once the appellate court is satisfied, after hearing the
appeal, that the appeal involves a substantial question of law, it has to
formulate the question and direct issuance of notice to the respondent/s.
      32. Now, let us consider as to whether the present appeals involve
any substantial question(s) of law.                                                D

       33. The APTEL has recorded findings on 35 issues raised by the
appellants. According to the appellants, six issues decided by the APTEL
give rise to substantial question of law which are as follows:
       1.     Change in methodology in computation of AT&C Losses.                 E
       2.     Change in methodology for computation of Depreciation.
       3.     Disallowance of salary for FR/SR Structure.
       4.     Disallowance of interest incurred on Consumer Security
              Deposit retained by DPCL.
                                                                                   F
       5.     Disallowance of Fringe Benefit Tax.
       6.     Reduction in MUs in relation to Enforcement sale for the
              purpose of calculation of AT&C Losses (this issue deals
              with theft/unauthorized use of electricity).
       34. Mr. Arvind P. Dattar and Mr. Dhruv Mehta, learned senior                G
counsel appearing for the appellants, would submit that the findings of
the APTEL on Issue Nos.1, 2, 3 and 5 are contrary to the binding DERC
Tariff Regulations. It is argued that the Regulator cannot ‘change the
rules of the game after it has begun’ in the ‘truing up exercise’. In this
regard, they have taken us through the findings of the DERC in the                 H
810                SUPREME COURT REPORTS                         [2022] 14 S.C.R.


A     Tariff Order and also the findings of the DERC after the truing up stage.
      It is further argued that the tariff order is in the nature of a quasi-judicial
      determination and that in the guise of truing up, the DERC cannot amend
      a tariff order.
              35. On the other hand, Mr. Nikhil Nayyar, learned senior counsel
B     appearing for the respondent-DERC, submits that one of the facets of
      the tariff determination exercise is the process of ‘truing up’. Since the
      initial tariff order is prepared by the DERC, based on the projections
      submitted by the Discoms as its ARR petition, the subsequent tariff order
      is issued after the financial year pursuant to the ‘truing up’ exercise. It is
      also pointed out that the findings on the aforesaid six issues are neither
C     contrary to law nor opposed to any regulations.
             36. Having considered the submissions of the learned counsels
      for the parties and after perusing the Impugned Order, we are of the
      view that these appeals involve the following substantial questions of
      law:
D
             “On Issue No.1
             (a)     Whether the impugned findings on Issue No.1 are contrary

A                   (i)    Tariff must ensure recovery of all costs of undertaking
                           distribution of electricity with reasonable return,

                           it has begun” in the ‘truing up exercise’?
B           (b)     Whether the impugned findings violate the principles and
                    methodology for tariff determination specified in the binding
                    DERC’s Tariff Regulations?
            On Issue No.6
            (a) Whether the impugned Findings on Issue No.6 are contrary to
C           the mandate of Sections 3, 61(b), (c), (d) and (e), 62, 64 (read
            with the Tariff Policy) and 86(3) of the 2003 Act in terms of
            which Tariff must ensure recovery of all costs of undertaking

D           (b) Whether the impugned findings are against settled law that

            with all its consequences i.e. same quantum of energy is to be
            accounted for as supplied?
E            37. One of the substantial questions of law raised on four issues
      (Issue Nos.1, 2, 3 and 5) is whether it is permissible to amend the tariff
      order made under Section 64 of the 2003 Act during the ‘truing up’
      exercise which needs to be answered before answering each of the
      aforesaid issues.
F            38. Section 82 of the 2003 Act envisages the constitution of a
      State Electricity Regulatory Commission. By virtue of Section 84 of the
      Act, such State Commission comprises of a Chairperson and Members,
      being persons possessing “ability, integrity and standing who have
      adequate knowledge of, and have shown capacity in, dealing with
      problems relating to engineering, finance, commerce, economics,
G     law or management”, with the Chairperson being a person who is, or
      has been, a Judge of a High Court.
              39. DERC, constituted under Section 82 of the 2003 Act, is an
      expert body vested with wide powers and functions under the Act. This
      includes the power to frame regulations and the power to determine
H     tariff.
   BSES RAJDHANI POWER LTD. v. DELHI ELECTRICITY                              813
    REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

        40. Under Section 86 of the 2003 Act, the State Commission            A
carries out various functions including determination of “the tariff for
generation, supply, transmission and wheeling of electricity,
wholesale, bulk or retail, as the case may be, within the State”. The
process of determination of tariff in the present case, as part of the
broader regulatory power of the Commission, is to be done in accordance
                                                                              B
with Section 62 and 64 of the 2003 Act. As per Section 62, the Appropriate
Commission (the State Commission in the present case) shall determine
the tariff in accordance with the provisions of the Act for inter alia
retail supply of electricity.
      41. In addition to the above functions, the State Commission is
also vested with the power to make regulations, under Section 181 of          C
the 2003 Act, - dealing with inter alia “the terms and conditions for
determination of tariff under Section 61” and “issue of tariff order
with modifications or conditions under sub-section (3) of Section
64”.
       42. It is pertinent to note that while framing the Regulations, the    D
State Commission is required to be guided by the principles specified in
Section 61 of the 2003 Act.
      43. In framing such regulations, the Commission, as an expert
policy making body, is entrusted with the duty of striking a balance
between the various competing concerns and interests. This balance is         E
expressed in the DERC (Terms and Conditions for Determination of
Wheeling Tariff and Retail Supply Tariff) Regulations, 2007 (“2007 MYT
Regulations”) which are the relevant regulations governing the issues in
the present case.
       44. DERC, for a given Multi-Year period (also called the Control       F
Period), frames regulations for determination of tariff. DERC then
determines the ARR for the said Control Period in a Tariff Order known
as the Multi-Year Tariff Order based on the data available.
        45. It is also necessary to note that sub-section (6) of Section 62
of the 2003 Act mandates that the Tariff Order shall continue to be in        G
force for such period as may be specified in the Tariff Order unless
amended or revoked. Therefore, if any of the parties are aggrieved by
any of the clauses in the Tariff Order, they are at liberty to seek its
amendment or revocation under this provision. Secondly, the said order
is also appealable under Section 111 of the 2003 Act before the Appellate
                                                                              H

A     Tribunal and thereafter before this Court under Section 125. The Tariff
      Order made under Section 64 is quasi-judicial in nature and it is binding
      as-it-is on the parties unless it is amended or modified in a process
      known to law.
               46. Mr. Arvind Datar and Mr. Dhruv Mehta, learned senior counsel
B     appearing for the appellants have submitted that ‘truing up’ cannot be
      used to upset the methodology used for determination of ARR. According
      to them, such a conduct essentially amounts to ‘changing the rules of the
      game after the game has started’ or ‘changing the goal post’ with the
      sole intention to deny legitimate allowances to the appellants. It is also
      argued that ‘truing up’ stage is not an opportunity for the DERC to re-
C     think de novo on the basic principles, premises and issues involved in
      the initial projections of revenue requirement of the licensee. It was also
      argued that DERC has no unfettered power to control the tariff
      determination process as well as ‘truing up’ exercise.
               47. On the other hand, Mr. Nikhil Nayyar, learned senior counsel
D     appearing for the respondent-DERC, has submitted that one of the facets
      of tariff determination exercise is the process of ‘truing up’. Since the
      initial tariff order is prepared by the DERC based on projections submitted
      by the Discoms with its ARR petition, the subsequent tariff order is
      issued after the financial year pursuant to the ‘truing up’ exercise. The
      process of ‘truing up’ requires the DERC to carry out a prudence check.
E     A prudence check is not a mere accounting or mathematical exercise. A
      prudence check requires a scrutiny of reasonableness of the expenditure
      incurred or proposed to be incurred by the Discoms and also such other
      factors that the DERC considers appropriate for determination of tariff.
      DERC being an expert body, due deference ought to be given to their
F     understanding as recorded in various regulations. It is argued that the
      controlling factor throughout the entire ‘truing up’ exercise is the MYT
      Regulations itself. It is further argued that the tariff determination exercise
      carried out by the DERC is a continuous process. The tariff determination
      exercise includes the initial tariff order - in the instant case it is 23.02.2008
      --- a ‘truing up’ inter alia the ARR and Multi-Year Tariff Order for the
G     years, F.Y. 2007-08 to F.Y.2010-11, as well as the subsequent Tariff
      Order dated 26.08.2011, inter alia, ‘true up’ for F.Y. 2008-09 and F.Y.
      2009-10. Mr. Nayyar has placed reliance on the judgment of this Court
      in Gujarat Urja Vikas Nigam Limited v. Tarini Infrastructure
      Limited & Others2 in support of his submissions.

       REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

       48. We have carefully considered the submissions of the learned               A
senior counsel for the parties. We have already noticed that the State
Electricity Regulatory Commissions constituted under Section 82 of the
2003 Act are a multi-member body comprising a Chairperson and
members being persons having adequate knowledge, of ability, integrity
and standing who have adequate knowledge, and have shown capacity,
                                                                                     B
in dealing with problems relating to engineering, finance, commerce,
economics, law or management, with the Chairperson being a person
who is or has been Judge of a High Court. Under Section 86 of the 2003
Act, the State Commission carries out various functions including
determination of tariff for generation, supply, transmission and wheeling
of electricity in wholesale, bulk or retail as the case may be within the            C
State. The process of determination of tariff has to be done in accordance
with Sections 62 and 64 of the 2003 Act. It is well settled that the
Commission (in this case, the DERC) performs a quasi-judicial function
while determining tariff. This has been expressly recognized by the
Constitution Bench of this Court in PTC India Limited v. Central
                                                                                     D
Electricity Regulatory Commission, Through Secretary3 as under:
         “50. Applying the above test, price fixation exercise is really
         legislative in character, unless by the terms of a particular statute
         it is made quasi-judicial as in the case of tariff fixation under Section
         62 made appealable under Section 111 of the 2003 Act, though
         Section 61 is an enabling provision for the framing of regulations          E
         by CERC. If one takes “tariff” as a subject-matter, one finds that
         under Part VII of the 2003 Act actual determination/fixation of
         tariff is done by the appropriate Commission under Section 62
         whereas Section 61 is the enabling provision for framing of
         regulations containing generic propositions in accordance with              F
         which the appropriate Commission has to fix the tariff. This basic
         scheme equally applies to the subject-matter “trading margin” in
         a different statutory context as will be demonstrated by discussion
         hereinbelow.”
       49. The DERC determines the tariff of the licensee under Section              G
62 in such a manner as determined by the 2007 MYT Regulations. This
function is governed, inter alia, by safeguarding all consumers’ interest
and at the same time recovering the cost of electricity in a reasonable
manner, such that ‘distribution and supply of electricity are conducted

A     on commercial principles’ which encourage and reward competition,
      efficiency, economic use of resources, good performance and optimum
      investments.
             50. DERC determines ARR of the licensee i.e. costs of undertaking
      the licensed business which are permitted in accordance with the
B     requirement specified by DERC which is to be recovered from the tariff
      in the year end. ARR determined by DERC is based on projections.
      Since the tariff and the ARR are regulated, the Discoms cannot recover
      anything more than from its consumers than what is allowed by the
      DERC.
C             51. As noticed above, a tariff order is quasi-judicial in nature which
      becomes final and binding on the parties unless it is amended or revoked
      under Section 64(6) or set aside by the Appellate Authority. Apart from
      this, we are also of the view that at the stage of ‘truing up’, the DERC
      cannot change the rules/methodology used in the initial tariff determination
      by changing the basic principles, premises and issues involved in the
D     initial projection of ARR.
             52. ‘Truing up’ has been held by APTEL in SLDC v. GERC4 to
      mean the adjustment of actual amounts incurred by the Licensee against
      the estimated/projected amounts determined under the ARR. Concept
      of ‘truing up’ has been dealt with in much detail by the APTEL in its
E     judgment in NDPL v. DERC5 wherein it was held as under:-
               “60. Before parting with the judgment we are constrained to
               remark that the Commission has not properly understood the
               concept of truing up. While considering the Tariff Petition of the
               utility the Commission has to reasonably anticipate the Revenue
F              required by a particular utility and such assessment should be
               based on practical considerations. … The truing up exercise is
               meant (sic) to fill the gap between the actual expenses at the end
               of the year and anticipated expenses in the beginning of the year.
               When the utility gives its own statement of anticipated expenditure,
G              the Commission has to accept the same except where the
               Commission has reasons to differ with the statement of the utility
               and records reasons thereof or where the Commission is able to
               suggest some method of reducing the anticipated expenditure.

     REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

      This process of restricting the claim of the utility by not allowing      A
      the reasonably anticipated expenditure and offering to do the
      needful in the truing up exercise is not prudence.”
        53. This view has been consistently followed by the APTEL in its
subsequent judgments and we are in complete agreement with the above
view of the APTEL. In our opinion, ‘truing up’ stage is not an opportunity      B
for the DERC to rethink de novo on the basic principles, premises and
issues involved in the initial projections of the revenue requirement of
the licensee. ‘Truing up’ exercise cannot be done to retrospectively change
the methodology/principles of tariff determination and re-opening the
original tariff determination order thereby setting the tariff determination
process to a naught at ‘true-up’ stage.                                         C

       54. In Gujarat Urja Vikas Nigam Ltd. (supra), this Court was
considering a case where tariff was incorporated in the power purchase
agreement between a generating company and a distribution licensee.
This Court held that it is not possible to hold that the tariff agreed by and
between the parties, though finding a mention in a contractual context, is      D
the result of an act of volition of the parties which can, in no case, be
altered except by mutual consent. We are of the view that this judgment
is not applicable to the facts of the present case.
       55. Revision or re-determination of the tariff already determined
by DERC on the pretext of prudence check and truing up would amount             E
to amendment of the tariff order, which can be done only as per the
provisions of sub-Section (6) of Section 64 of the 2003 Act within the
period for which the Tariff Order was applicable. In our view, DERC
cannot amend the tariff order for the period 01.04.2008 to 31.03.2010 in
the guise of ‘true-up’ after the relevant financial year is over and the        F
same is replaced by a subsequent tariff Order. This would amount to a
retrospective revision of tariff when the relevant period for such tariff
order is already over. Therefore, we hold that it is not permissible to
amend the tariff order made under Section 64 of the 2003 Act during the
‘truing up’ exercise.
                                                                                G
       56. Issue Nos. 1, 2, 3, and 5: We have already noticed that one
of the substantial questions of law involved in Issue Nos.1, 2, 3 and 5 is
whether the Regulator can ‘change the rules of the game after it has
begun’ in the ‘truing up exercise’.

                                                                                H
818             SUPREME COURT REPORTS                         [2022] 14 S.C.R.


A            57. Issue No. 1: In the original MYT determination (Tariff Order
      dated 28.05.2009), the DERC took into account the full late payment
      surcharge (‘LPSC’) revenue as also the DVB arrears while computing
      the targets of Collection Efficiency as under:-
                “3.10. An analysis of the components of AT&C loss level
B               indicates that the revenue collection on account of sale of energy
                was Rs.2810.3 Crs. However, this amount could not be verified
                from the audited accounts of the petitioner. The petitioner has,
                instead, submitted a daily collection sheet to substantiate its
                collection of Rs.2810.3 Crs.
                3.11 The Commission is not receptive to the methodology of
C               verifying the collection from the Daily Collection Sheet as
                proposed by the petitioner. Accordingly, the petitioner was
                directed during the validation session to reconcile the amount
                of cash collected bases on the opening levels of debtors, sales
                made during the year, DVB arrears collected and the closing
D               level of debtors, with the total collections shown for FY 07-08.
                However, the petitioner expressed inability to reconcile the
                figures using this methodology.
                3.12. The petitioner was, thereafter, directed to provide a copy
                of the daily collection sheet duly audited by its Statutory
E               Auditors. The petitioner was also directed that the Statutory
                Auditors should establish that the amount mentioned in the Daily
                Collection Sheet does not included any collections on account
                of other sources of revenue like sale of power through bilateral,
                intra-state, UI, etc. and revenue from operations (non-energy).
                3.13. In response to the above, the petitioner submitted a copy
F               of its Statutory Auditor’s certificate certifying the Day-wise
                Collection Statement for FY 07-08 vide its letter no.RCM/08-
                09/245 dated 16th February, 2009. The Certificate clarified the
                exclusion of collections made on account of trading of energy,
                non-energy charges, subsidy received from GoNCTD, etc. and
G               inclusion of LPSC, electricity duty, amount collected by BYPL
                on behalf of BRPL, etc.
                3.14. Accordingly, based on the clarifications provided in the
                statutory auditor’s certificate and the audited financial
                statements, the amount mentioned in the Daily Collection Sheet
                submitted by the petitioner has been taken into account.

       58. However, while truing up for the year in question, the DERC
has retrospectively sought to take away part of the LPSC revenue by
deducting the Financing Cost on LPSC in comparing the actual Collection      E
Efficiency with the projected Collection Efficiency. Hence, allowing the
Financing Costs on LPSC revenue and then deducting it from the LPSC
revenue would tantamount to giving by one hand and taking it away by
the other. This order of the DERC is contrary to the original MYT
determination.
                                                                             F
        59. Issue No.2: In the Original Determination Order dated
28.05.2009 (F.Y. 2008-09), DERC has allowed depreciation on the assets
funded by consumer contributions. However, DERC changed the
methodology of computation of ARR at the stage of true up. According
to the learned counsel for the respondent, DERC had inadvertently made
an error and adopted an approach contrary to the mandate of 2007 MYT         G
Regulations while computing the depreciation when originally issuing
the tariff order, which was rectified in the true up exercise. However,
learned counsel for the appellants submit that no error has been committed
by the DERC in the tariff order dated 28.05.2009 and it is only after
considering the relevant MYT Regulations that depreciation to the
                                                                             H

A     appellants on the assets that were funded by consumer contributions
      was allowed.
             60. Perusal of the Tariff Order dated 28.05.2009 would clearly
      indicate that after considering the contentions of the parties the aforesaid
      depreciation has been allowed. We have already held that it is not
B     permissible to amend the tariff order during true up exercise. On the
      pretext of prudence check and truing up, DERC could not have amended
      the tariff order.
             61. Issue No.3 : During projection of expenses for the entire
      control period, the Tariff Order dated 23.02.2008 had projected employee
      expenses considering inter alia the impact of the anticipated Sixth Central
C     Pay Commission Report. The relevant portion of the said Tariff Order is
      as under:
             “4.99 The Petitioner has submitted the employee expenses for
             FY07 as Rs 137.60 Cr and has considered the same as the
             base for the Control Period. The Petitioner has considered
D            the following factors while projecting the escalation factor
             for the employee expenses for the Control Period:
             (a) Anticipated 6th Pay Commission report
             (c) Research of lead HR consultants on salary trends in the
             country
E            (c) Initiatives undertaken to retain quality manpower and
             demand for employees in the power industry.
             (d) Inflation during last 12 months € increase in employees to
             cater to growth of consumers.
             4.100 The Petitioner has projected its total employee expenses
F            for the Control Period considering different escalation rates
             for different components of the employee expenses. The annual
             growth rates for various components of employee expenses
             as proposed by the Petitioner are given below:
             (a) Basic Salary: The year on year increase in basic salary
G            for all the employees during the Control Period has been
             estimated at 23.2%, 11.1%, 11.3%, and 11.5% for FY08,
             FY09, FY10 and FY11 respectively.
             (b) Dearness Allowance (DA): Annual estimated increase in
             DA is considered as 9%, 6%, 6%, and 6% for FY08, FY09,
             FY10 and FY11 respectively.

      (c) Terminal Benefits: Contribution to terminal benefits/              A
      liability fund is considered at 26% of basic salary and
      dearness allowance for each year of the Control Period.
      (d) Other Allowances and expenses including HRA: Considered
      in proportion to the basic salary.”
       62. The DERC, while projecting employee expenses for the entire       B
control period in its MYT Tariff Order dated 23.02.2008, had categorically
acknowledged the uncontrollable nature of the Sixth Central Pay
Commission Report as well as the impact of the same on the salaries of
FR&SR employees and held that since the salary of FR&SR employees
was an uncontrollable item and that it would be trued up on actuals as       C
under:
      “4.108 During the privatization process, part of the employees
      of the erstwhile DVB were transferred to BRPL. As per the
      Transfer Scheme, the terms and conditions of service
      applicable to the erstwhile Board employees in the Transferee          D
      Company shall in no way be less favourable than or inferior
      to that applicable to them immediately before the Transfer.
      Further, their services shall continue to be governed by various
      rules and laws applicable to them prior to privatization. Thus
      the salary/compensation and promotion of the erstwhile DVB
      employees in BRPL are still governed by the rules and pay              E
      scales as specified by the GoNCTD.
      4.109 In consideration of the above, the Commission has
      recognized the uncontrollable nature of the 6 th Pay
      Commission recommendations in determination of employee
      expenses during the Control Period. The Commission has                 F
      assumed that the revision in pay, if any, shall be applicable
      from January 1, 2006. The Commission has considered an
      increase of 10% in total employee expenses for the values in
      FY06 (3 months) and FY07 due to the same.
      …                                                                      G
      4.112 Similarly, the increase in salaries has been considered
      for each year, but the impact of such increase has only been
      taken from FY09 onwards. The Commission shall true-up the
      impact on account of 6th Pay Commission recommendations
      based on the actual impact of the same.                                H

            4.114 For the calculation of the employee expenses for the
            Control Period, the Commission has considered the following:
            (a) Revised employee expenses for the base year have been
D
            escalated as per the escalation factors mentioned in Table 67
            to arrive at the employee expenses for the Control Period.
            (b) All arrears due to the impact of the 6th Pay Commission
            recommendations would be payable in FY09. For the purpose
            of projecting the arrears arising due to recommendation of
E           the 6 th Pay Commission for FY08, the Commission has
            considered the difference between the employee expenses for
            FY08 arrived by escalating the revised employees expenses
            for FY07 (i.e. Rs 146.19 Cr) and the employees expenses for
            FY08 arrived by escalating the trued up employee expenses
F           (net of SVRS amortization) for FY07 (i.e. Rs 137.60 Cr).”
             63. However, contrary to its own undertaking, the DERC in Tariff
      Order dated 26.08.2011 has erroneously changed its own methodology
      at the stage of truing up, by not allowing employee expenses of FR/SR
      employees as per actuals. The DERC, at the stage of truing up, has
G     changed the methodology and disallowed the actual salary of FR&SR
      employees, which is impermissible. The DERC in the Tariff Order dated
      26.08.2011 has acted contrary to its own undertaking of truing up the
      impact of employee expenses on account of the Sixth Central Pay
      Commission Report.

    REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

       64. Issue No.5 : This issue is in relation to disallowance of fringe   A
benefit tax. The DERC has allowed fringe benefit tax in the MYT Order
dated 23.02.2008. Relevant extract of the MYT Order dated 23.02.2008
is as under:
      “Commission’s Analysis
      4.242 The Commission is of the opinion that projecting the              B
      actual tax liability for the Control Period is difficult and
      complex. Thus for simplicity, the Commission provisionally
      approves Rs 5.00 Cr each year towards income tax and fringe
      benefit expenses. The Commission would, however, true-up
      the tax expenses based on the actual tax liability at the end of        C
      each year of the Control Period.The Commission has allocated
      the tax expenses into Wheeling and Retail Supply in the ratio
      of 20:80, respectively.”
       65. The DERC, at the stage of truing up for the F.Y. 2008-09, has
changed the methodology and disallowed the fringe benefit tax incurred        D
by the appellants.
        66. We have already taken a view that DERC cannot re-open the
basis of determination of tariff at the stage of ‘truing up’. Revision or
redetermination of the tariff already determined by the DERC on the
pretext of prudence check and truing up would amount to amendment of          E
tariff order, which is not permissible in law. Truing up stage is not an
opportunity for DERC to re-think de novo the basic principles, premises
and issues involved in the initial projection of the revenue requirements
of the licensee.
      67. Therefore, the findings of the DERC, as confirmed by the            F
APTEL in the impugned order, on issue nos. 1, 2, 3 and 5 are contrary to
the order of the original MYT determination (Tariff Order(s) dated
23.02.2008 and 28.05.2009) which are accordingly set aside. In view of
the above, it is unnecessary for us to consider the other substantial
questions of law on the aforesaid four issues.
                                                                              G
       68. Issue No.4: This issue relates to disallowance of interest
incurred on Consumers Security Deposit retained by Delhi Power
Company Limited (‘DPCL’). The DERC in the tariff order dated
26.08.2011 has disallowed the interest on Consumers Security Deposit
paid for pre-privatization period received by DVB, which is yet to be
transferred to the appellants. The APTEL has confirmed this order of          H
824             SUPREME COURT REPORTS                          [2022] 14 S.C.R.


A     the DERC. It is to be stated here that, at the time of unbundling of the
      erstwhile DVB (w.e.f. 01.07.2022), the quantum of Consumers Security
      Deposit reflected in the opening balance-sheet notified in terms of
      statutory transfer scheme, was not transferred by the DPCL (the Holding
      Company wholly owned by the Government of NCT of Delhi) to the
      appellants and other successor private Discoms. The appellants being
B     distribution licensees under the 2003 Act are required to and are
      continuing to pay interest on the said Consumers Security Deposit in
      terms of Section 47(4) of the 2003 Act even though the principal sum
      was never transferred to them in its entirety by DPCL.
              69. The DERC by its order dated 23.04.2007 has held that it does
C     not have power to issue any directions to DPCL.
              70. Learned counsel for the respondent-DERC submits that the
      appellants have sought transfer of deposits along with interest from DPCL
      and the issue of DPCL to make this payment is pending before the Delhi
      High Court in W.P. (Civil) No.2396/2008. It is further submitted that,
      should the appellants succeed in their claim against DPCL and receive
D     the deposit amount along with interest, the amount would be made over
      to the appellants along with interest. As such, if the expenses were to be
      presently allowed in the ARR, and interest burden was passed on to the
      consumers presently, the Discoms would, in effect, receive double benefit
      at the time of disposal of the writ petition since the consumers would
E     have already borne the costs of interest which would also be then made
      over by DPCL to the appellants. It is argued that, as a Regulator, it is
      incumbent upon the DERC to protect the consumers’ interest.
              71. We are of the view that disallowing interest paid by the
      appellants towards Consumers Security Deposit held by DPCL in the
      ARR of the appellants is wholly misconstrued. Interest on consumers’
F     deposit which is being paid by the appellants is a legitimate expense. It is
      not in dispute that the security deposit was not transferred by the DPCL
      to the appellants. However, the appellants were required to bear the
      costs of the same. In case, the principal sum on Consumers Security
      Deposit held by DPCL is transferred to the appellants with interest, the
      appellants would, subject to their legitimate expenditures, retain such
G
      interest and benefit of any balance of excess interest received by the
      appellants would be passed on to the consumers in tariff. Therefore,
      there is no merit in the contention of the learned counsel for the respondent
      that if the interest burden is passed on to the consumers presently, the
      appellants would, in effect, receive a double benefit in case they succeed
H     in the writ petition pending before the High Court.

     REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

        72. Therefore, we hold that the appellants are entitled to recover      A
interest on Consumers Security Deposit as held by the DPCL. We direct
the DERC to allow the interest on Consumers Security Deposit held by
the DPCL and impact thereof to the appellants. The findings of the
DERC and the APTEL in this regard are set aside.
        73. Issue No.6: This issue pertains to enforcement sales i.e.           B
sales which are deemed to have been occurred in cases of electricity
theft. The question for consideration is whether the impugned findings in
the order of the APTEL are against the legal principle that when the
statute creates a legal fiction i.e. energy assessed is ‘deemed’ to be
consumed, the same has to be given effect to with all its consequences
i.e. same quantum of energy is to be accounted for as supplied?                 C
        74. Electricity transmitted may be stolen or used unauthorizedly.
While theft/unauthorized use was approximately 60% before privatization,
it has now been brought down to 7 to 8%. Unauthorized use and theft
are dealt with in Section 126 of the 2003 Act, relevant clauses whereof
are as under:                                                                   D
        “Section 126: (Assessment): — (1) If on an inspection of any
        place or premises or after inspection of the equipments, gadgets,
        machines, devices found connected or used, or after inspection of
        records maintained by any person, the assessing officer comes to
        the conclusion that such person is indulging in unauthorized use of     E
        electricity, he shall provisionally assess to the best of his
        judgement the electricity charges payable by such person
        or by any other person benefited by such use.
        […]
        [(5) If the assessing officer reaches to the conclusion that
                                                                                F
        unauthorised use of electricity has taken place, the assessment
        shall be made for the entire period during which such unauthorized
        use of electricity has taken place and if, however, the period during
        which such unauthorised use of electricity has taken place cannot
        be ascertained, such period shall be limited to a period of twelve
        months immediately preceding the date of inspection.]                   G
        (6) The assessment under this section shall be made at a
        rate equal to twice the tariff rates applicable for the relevant
        category of services specified in sub-section (5).”
                                                        (Emphasis supplied)
                                                                                H
826             SUPREME COURT REPORTS                           [2022] 14 S.C.R.


A             75. The Vigilance/Enforcement Department detects theft/
      unauthorized use of electricity. After giving due opportunity, the bills are
      generated for electricity stolen/unauthorized use. These are called
      enforcement sales/assessed sales. The statutory charge for such theft/
      unauthorized use is twice the normal rate.
B             76. While settling enforcement cases of small consumers, Lok
      Adalats often provide discounts to errant consumers on the assessed
      equivalent of the rupee amount and not on the assessed units of energy.
      The assessment of units of energy as deemed to be sales to the consumers
      is in accordance with Section 126 of the 2003 Act read with provisions
      for such assessment specified by the DERC itself.
C             77. In a particular case of unauthorized use of electricity under
      Section 126, suppose using the ‘LDHF formula’ (specified by DERC
      itself), the appellants assess the consumer as having consumed 100 units
      of electricity.
              (a) By virtue of the Supply Code Regulations framed by the
D                    DERC itself, these 100 units are to be treated as “sales”.
              (b) Upon the assessment of 100 Units, the Appellant raises a
                     bill on the said consumer. Under Section 126 of the
                     Electricity Act, the bill has to be raised at twice the normal
                     billing rate. If the normal ABR were Rs. 5 per Unit, the
E                    Section 126 Bill will be raised for Rs 1,000 (i.e. 100×[Rs
                     5×2]);
              (c) By virtue of a Settlement which is entered into between
                     the Appellant and the consumer before the Lok Adalat etc.,
                     suppose the Appellant agrees to give up Rs 200, the
                     Appellant then recovers Rs 800/- rather than Rs 1,000/-.
F
              (d) Now, though the settlement is only for the Rupee equivalent
                     of the Assessed Bill and not the ‘Units sold’, the DERC
                     now takes Rs 800, divides it by Rs 10 (i.e. twice the ABR)
                     and arrives at an imaginary ‘sales’ figure of electrical energy
                     of 80 Units.
G
              (e) This is in complete contrast to the Assessment of Energy
                     sold of 100 Units in terms of the LDHF Formula specified
                     by the DERC itself according to which the sales are
                     “deemed to be” 100 units.
              (f)    Therefore, by entering into a settlement before the Lok
H                    Adalat (which is in harmony with the entire Lok Adalat
    BSES RAJDHANI POWER LTD. v. DELHI ELECTRICITY                             827
     REGULATORY COMMISSION [S. ABDUL NAZEER, J.]

               philosophy), the Appellant first loses Rs 200 in monetary      A
               terms and then loses 20 Units of electricity which the
               Appellant is deemed to have sold such consumer in the
               first place.
       78. Learned counsel for the appellants submit that when the statute
creates a legal fiction, i.e. energy assessed is deem to be consumed, the     B
same has to be given effect to with all its consequences i.e. same quantum
of energy is to be accounted for as supplied. However, learned counsel
appearing for the respondent DERC submitted that that concurrent findings
of the DERC and the APTEL cannot be reversed and the methodology
adopted by the Commission has to be maintained.
       79. Having considered this question in detail, we are not in           C
agreement with the stand taken by the respondent. We are of the view
that the methodology adopted by the DERC is contrary to the settled
principle of law that when the law deems a certain imaginary state of
affairs as real, DERC would not let its imagination boggle at treating the
100 units as sales. We are of the view that such imaginary state of           D
affairs must be taken to its logical end and commend the treatment of
100 units as ‘sales’.
       80. We are of the view that the assessed energy has to be
considered as supply by the appellants in enforcement cases. Therefore,
we direct the DERC to consider assessed energy for calculation of             E
enforcement sales and allow the impact of the same along with carrying
costs. In view of our conclusion as above, we do not deem it necessary
to answer the other contentions on this issue.
       81. The substantial questions of law are answered accordingly.
Resultantly, the appeals are allowed and the order(s) of the DERC and
the judgment of the APTEL impugned herein, to the extent mentioned            F
above. are hereby set aside. Parties to bear their respective costs.

Nidhi Jain                                                 Appeals allowed.
