REPORTABLE

IN THE SUPREME COURT OF INDIA

CIVIL APPELLATE JURISDICTION

CIVIL APPEAL No. 8747 of 2014

TRANSMISSION CORPORATION OF 

ANDHRA PRADESH LTD. AND OTHERS   .......APPELLANT(S)

VERSUS

M/s. GMR VEMAGIRI POWER

GENERATION LTD. AND ANOTHER        ......RESPONDENT(S)

JUDGMENT

NAVIN SINHA, J.

The controversy for determination in the present appeal

is, whether the word ‘fuel’ as used in clause 1.1.27 of the

Power Purchase Agreement (hereinafter referred to as ‘PPA’)

means   “natural   gas   only”   or   includes   Regasified   Liquefied

Natural Gas (hereinafter referred to as ‘RLNG’) also.

2.The Andhra Pradesh Electricity Regulatory Commission

(hereinafter referred to as “the Commission”), in O.P. No. 20 of

2013 dated 08.08.2013, preferred by the respondent, held that

the term ‘fuel’ as used in the PPA meant natural gas only in its

natural form, and did not include RLNG.  Simply because the

physical composition of natural gas and RLNG are similar, it

does   not   automatically   entitle   the   respondent   to   generate

power   with   RLNG,   which   was   more   expensive   and   not

domestically available, affecting the per unit supply of power

generated by it, as ultimately the consumer would have to pay

more.

3. In Appeal No. 222 of 2013 preferred by the respondent,

the   Appellate   Tribunal   by   the   impugned   order   dated

30.06.2014 held that use of the word “only” after “natural gas”

in the PPA dated 02.05.2007 had to be understood in context

of the deletion of other alternate fuel such as Naphtha etc.

incorporated in the earlier PPAs, and it was never intended to

restrict the meaning of the word natural gas to exclude RLNG,

2

which was a variant of natural gas and did not come in the

category of an alternate fuel.  It further held that the higher

price of RLNG could not be a determinative factor to exclude it

from the agreement as any increase in price of gas was an

accepted   risk,   especially   in   view   of   the   non­availability   of

natural gas from the KG­D6 basin.  The use of RLNG had also

been permitted on earlier occasions without any amendment

to the PPA.

4.The predecessor of the appellant, the Andhra Pradesh

State   Electricity   Board,   in   May,   1995   invited   bids   for

establishing     short   gestation   gas/Naphtha/fuel   oil   based

power stations to bridge the demand supply gap of power in

the State of Andhra Pradesh.   Pursuant to the same, a PPA

was executed between the parties on 31.03.1997 under which

Naphtha   was   the   primary   fuel   and   gas   an   alternate   fuel.

Considering the high price of Naphtha, in March 2000, the

Government   of   Andhra   Pradesh   decided   to   make   gas   the

primary   fuel.     The   Ministry   of   Petroleum   on   05.06.2000

3

allotted 1.64 MMSCMD of natural gas to the respondent from

the KG­D6 Basin sourced through the Gas Authority of India

Ltd   (GAIL),   leading   to   a   gas   supply   agreement   dated

31.08.2001 between the respondent and the latter.  The PPA

was   accordingly   amended   on   18.06.2003   making   gas   the

primary   fuel   and   Naphtha   an   alternate   fuel.     The   PPA

underwent further amendment on 02.05.2007, restricting the

term ‘fuel’ to “natural gas only”.  A comparative status of the

three PPA’s can beneficially be set out as follows:

fuel.”

5.GAIL   having   been   unable   to   supply   gas   under   the

agreement   due   to   prioritisation   of   other   sectors,   the

respondent was permitted to purchase natural gas from M/s.

Reliance Industries Ltd (RIL) at GAIL prices.  The respondent,

on 07.08.2012 and 27.08.2012, sought permission to allow

use of RLNG as fuel for generating power.   The appellant

rejected the request on 10.09.2012 stating that under the PPA

dated 02.05.2007, fuel meant “natural gas only” and did not

include RLNG, which was priced much higher affecting the per

unit price of power generated from the same to the ultimate

detriment of the consumers.

6.Shri   Basava   Prabhu   Patil,   learned   senior   counsel

appearing for the appellant, submitted that under the PPA, it

was only natural gas in its natural form which was agreed to

be used as fuel for generation of power.  Merely because RLNG

5

may be a variant of natural gas, will not suffice to bring it

within the definition of fuel under the PPA.  The cost of RLNG

being   three   to   four   times   higher   than   natural   gas,   the

Commission rightly held that it was also a relevant factor to

hold   that   RLNG   was   never   intended   by   the   parties   to   be

included in the agreement. 

7. The word ‘fuel’, as defined in the agreement, had to be

given its natural meaning by confining it to natural gas only as

intended by the parties.  The definition could not be extended

so as to include RLNG, as the parties never intended the same.

There is no ambiguity in language warranting any inclusion to

the definition either by implication or intention.  Even if there

was   any   ambiguity   with   regard   to   the   intendment   of   the

parties, the true intent has to be gathered from the plain

meaning   of   the   words   used,   read   conjunctively   with   all

surrounding   circumstances   and   documents.     Applying   the

common   parlance   test,   RLNG   was   not   synonymous   with

natural   gas   in   the   business   and   neither   interchangeable,

6

because of the additional processes required in the latter and

the resultant higher cost involved including importation, as

distinct   from   natural   gas   available   at   a   lesser   price   and

domestically. 

8.Under   the   PPA   dated   31.03.1997,   Naphtha   was   the

primary fuel and gas was an alternate fuel.  Clause 3.3 dealing

with energy charge defined cost of fuel based on indigenous

and importation cost.  The PPA contemplated approval of the

fuel supply agreement by the fuel supply committee, to ensure

reasonable   prices   as   the   cost   of   power   generation   was   of

paramount consideration in the interest of the consumer.  The

cost of Naphtha being higher, the PPA came to be amended on

18.06.2003 making natural gas the primary fuel, and Naphtha

an alternate fuel.  If RLNG was in contemplation of the parties,

and was considered to fall within the term natural gas, there

would   have   been   some   discussion   regarding   it   in   the

deliberations   of   the   Commission   while   approving   the

amendments   to   the   PPA,   especially   in   view   of   the   price

7

difference. Such absence makes it manifest that the parties

never intended to include RLNG in the term natural gas.  The

significance of the words “only” after “natural gas” in the third

PPA   dated   02.05.2007   cannot   be   lost   sight   of.   It   was

necessitated in context of the realization that the parties may

have resorted to other costly alternate fuels consequent to the

dismantling of the administered price mechanism and the fuel

supply committee.

9.The fact that RLNG may have been permitted to be used

for   a   short   period   of   seven   days   from   16.04.2009   to

23.04.2009 under pressing circumstances of a power crisis, by

special orders under Section 11 of the Electricity Act, 2003 or

again for a short duration from 15.02.2011 to 31.05.2011

cannot be stretched to contend that RLNG was intended to be

included within the term natural gas.   The cost of power

generated from natural gas was Rs.1.75 per KWH while that

from RLNG works out to Rs.4.63 per KWH and the financial

burden for this short duration is Rs.427 crores.  In March and

8

April use of RLNG was permitted at per unit generation cost of

Rs.9/­ compared to Rs.3/­ per unit with existing natural gas

leading to a financial burden of Rs.3.7 crores per day.  These

exceptions   can   never   be   construed   to   mean   the   norm   to

contend that use of RLNG was always in the contemplation of

the parties and was intended to be included within the term

natural   gas.   The   very   fact   that   the   respondent   sought

permission on 07.08.2012 and 27.08.2012 to use RLNG for

power   generation   makes   it   manifest   that   even   as   per   its

understanding,   RLNG   was   not   included   within   the   term

natural   gas   according   to   the   intent   of   the   parties.     The

appellant in its reply dated 10.09.2012 had reiterated that

RLNG did not fall within the ambit of the PPA which was

confined to natural gas only citing the cost difference of power

per unit also. 

10.A contract document had to be interpreted in accordance

with the language used, with reference to the context in which

it came to be prepared.  A technical view of an agreement, torn

9

out of context, cannot be taken to reinterpret the agreement

and arrive at a new finding with regard to the intendment of

the parties by including something which was never intended

to be included, to the prejudice of a party to the contract,

while   giving   an   undue   advantage   to  the   other.   A   primary

consideration will also be the understanding of the parties of

the terms of the contract and what was intended, as reflected

inter alia from their conduct.  The contract being a commercial

document, utmost importance had to be given to its efficacy.

11.Shri Vikas Singh, learned senior counsel appearing for

the Respondent, submitted that the original bid documents

permitted import of fuel also, and fuel tie up linkage was the

responsibility   of   the   bidder.   The   Respondent   invested

approximately   Rs.1153.10   crores   in   setting   up   the   power

generation plant, of which, 68.29% of the funding was from

banks   and   financial   institutions.     The   plant   has   operated

intermittently for approximately 64 months only in the last 11

years.     The   conduct   of   the   appellant   in   not   accepting

availability declaration with regard to RLNG was unjustified.

The appellant was well aware of the possibility of future hike

in gas prices, and more particularly after dismantling of the

11

administrated price mechanism inclusive of inflation, all of

which would make the gas prices market driven.  Therefore,

merely because the cost of RLNG was higher could not be a

ground to contend that it was never intended to be included

within the definition of natural gas or was contrary to interest

of   the   consumer.   RLNG   was   but   a   form   of   natural   gas,

compressed for transformation from gaseous to liquid state,

reducing the volume to facilitate transportation in a safe and

stable   manner.   Once   delivered   at   the   destination,   it   is

regasified and then supplied to the consumer.  Even according

to the dictionary meaning they are the same.

12.The deletion of the words “intended to be used” after the

words “natural gas”, as used in the second PPA, and the

replacement thereof in the third PPA by the words “natural gas

only” gave a much wider meaning and amplitude to the word

natural gas so as to take within its ambit RLNG also.   The

deletion of “importation charges” in the PPA dated 18.06.2003

was of no significance as RLNG was to be delivered at the

12

project site through the pipeline, and the cost of fuel was to be

at the metering point at the project site, which would be

inclusive of importation cost. Evidently there would be no

separate charges by GAIL towards importation of RLNG. So

long   as   the   supplies   were   at   GAIL   prices,   the   appellants

cannot raise objections with regard to price. 

13.The term natural gas has not been defined under the

PPA. The definition of natural gas in Section 2(za)(i) of the

Petroleum   and   Natural   Gas   Regulatory   Board   Act,   2006

(hereafter   referred   to   as   the   “PNGRB   Act”)   includes   both

liquefied natural gas (LNG) and RLNG. The appellants on more

than one occasion had themselves permitted use of RLNG for

production   of   power   in   2011,   2012   and   2013.     It   is

demonstrative of the fact that RLNG was never intended to be

excluded under the PPA.   It was only when the respondent

wrote to the appellant for operationalising the RLNG scheme,

that the appellant replied on 27.03.2015 raising objection to

RLNG being outside the terms of the PPA.  The respondent had

13

never sought permission from the appellant for use of RLNG

by its letters dated 07.08.2012 and 27.08.2012, but merely

given intimation about what was otherwise permissible under

the   PPA.   After   the   dismantling   of   the   administered   price

mechanism  and  the fuel Supply  Committee, there was  no

requirement for consent or approval of the appellant.

14.The appellant having itself permitted use of RLNG on

more   than   one   occasion,   cannot   contend   its   exclusion

especially   when   the   agreement   clearly   is   suggestive   of   its

inclusion.  Alternately, there had been waiver on part of the

appellant   by   having   permitted   its   use   on   more   than   one

occasion.  The appellant cannot be permitted to approbate and

reprobate.   Natural gas had been defined in  Association of

Natural Gas & Ors. vs. Union of India & Ors., 2004 (4) SCC

489. The plea that power generated by RLNG would be more

costly and not in the interest of the consumer is belied by the

fact that today the appellant is purchasing power at higher

14

rate. The Director General, Petroleum Planning and Analysis

Cell   had   now   fixed   price   for   marketing   including   pricing

freedom for gas to be produced from discoveries in deepwater,

ultra­deepwater and high pressure­high temperature areas for

the period 01.04.2016 to 31.09.2016 at US$ 6.61/MMBTU on

GCV   basis.     On  05.05.2016,   the   respondent   wrote   to  the

appellant informing that GAIL had communicated that ONGC

has indicated availability of the gas in the KG basin from its

deepwater fiels­S1 and VA fields at the rate of 6.3$/MMBTU

even which has not been acceded to, as being beyond the PPA.

15. We have considered the submissions on behalf of the

parties, and are not in agreement with the conclusions of the

Appellate Tribunal.

16.The original PPA dated 31.03.1997, provided for Naphtha

to be used as the primary fuel for generation of power and gas

was an alternate fuel. Importation was also permissible.  The

15

price was to be fixed by the fuel supply committee, both to

keep it reasonable, and to ensure that the cheaper option was

always   used.   In   March   2000,   the   Government   of   Andhra

Pradesh, due to the cost factor, decided to replace gas as the

primary fuel, and Naphtha was made an alternate fuel leading

to allotment of natural gas by the Ministry of Petroleum and

execution of an agreement between the respondent and GAIL.

The PPA was then amended on 18.06.2003 making gas the

primary fuel.  Subsequently, when GAIL was unable to supply

the   allocated   quantities   of   natural   gas   to   the   respondent

because of sector prioritisation, the respondent was permitted

to obtain supplies of natural gas from RIL.   The realisation

that in the circumstances, the generator could resort to use of

other costly fuels also, led to the third amended PPA dated

02.05.2007 confining the definition of ‘fuel’ to “natural gas

only”. 

17.It   is   relevant   to   notice   that   at   both   stages   of   the

amendment   to   the   PPA,   in   the   proceedings   before   the

16

Commission   under   Section   21(5)   of   the   Andhra   Pradesh

Electricity Reforms Act, 1998, the parties never referred to the

availability  of  RLNG  as  fuel contemplated  within the   term

“natural gas” and the discussion was confined to “natural gas

only”.  Had the parties intended otherwise, or the respondent

had any such inkling in mind of RLNG being a variant of

natural gas and consequently intended to be included in it,

coupled with its availability as compared to natural gas, surely

it would have figured in the discussion before the Commission.

The absence of the same, combined with RLNG having to be

imported, deletion of the importation clause in the PPA of

18.06.2003, the higher price of RLNG, leads to the inevitable

conclusion   that   it   was   never   in   the   contemplation   of   the

parties that RLNG was to be included in the term “natural gas”

even though it may be a variant of the same.   It stands to

reason that if Naphtha was removed as primary fuel because

of the cost factor and made an alternate fuel in the second

amendment to the PPA, the question of RLNG being included

17

within the term of “natural gas only” irrespective of the cost

factor, will not stand the test of reason.

18.A wrong question will inevitably lead to a wrong answer.

The question for consideration presently is not if RLNG is a

form   of   natural   gas,   but   whether   the   parties   intended   to

exclude   any   form   of   gaseous   fuel   from   the   ambit   of   the

contract except for natural gas in its natural form from the

domestic market, keeping the price of gas in mind, which

would ultimately set the price per unit of electricity for the

consumer. The PPA is a technical commercial document.   It

has been drafted by persons conversant with the business.

RLNG  and natural gas as  used  in the  agreement are not

synonymous   or   interchangeable.   The   principle   of   business

efficacy will also have to be kept in mind for interpreting the

contract.  The terms of the agreement have to be read first to

understand the true scope and meaning of the same with

regard to the nature of the agreement that the parties had in

mind.  It will not be safe to exclude any word in the same.  In

18

Khardah Company Ltd. vs. Raymon & Co. (India) Private,

Ltd., 1963 (3) SCR 183, on interpretation of a contract it was

observed as follows:

“18. …  We agree that when a contract has

been reduced to writing we must look only to

that writing for ascertaining the terms of the

agreement between the parties but it does not

follow from this that it is only what is set out

expressly   and   in   so   many   words   in   the

document that can constitute a term of the

contract between the parties. If on a reading of

the   document   as   a   whole,   it   can   fairly   be

deduced from the words actually used therein

that the parties had agreed on a particular

term, there is nothing in law which prevents

them from setting up that term. The terms of a

contract   can   be   expressed   or   implied   from

what has been expressed. It is in the ultimate

analysis   a   question   of   construction   of   the

contract. And again it is well established that

in construing a contract it would be legitimate

to   take   into   account   surrounding

circumstances…”

19.    It will not be a safe method to interpret a contract by

picking out one clause of the same defining fuel, apply a

technical   scientific   meaning   to   it   as   observed   in  Truetuf

Safety Glass Industries (supra) and then conclude that being

19

a form of natural gas, RLNG was intended to be impliedly

included in the definition of fuel.  The terms of a contract have

to be given their plain meaning with regard to the intendment

of the parties as to what was intended to be included and what

was not intended to be included, as distinct from an express

exclusion. The commercial parlance test will also have to be

applied as to whether those in the business consider the two

forms   of   gas   as   synonymous   and   interchangeable.   Quite

obviously the answer has to be in the negative considering the

importation of RLNG, additional processes involved and the

consequent higher costs involved. 

20. In the event of any ambiguity arising, the terms of the

contract   will   have   to   be   interpreted   by   taking   into

consideration   all   surrounding   facts   and   circumstances,

including   correspondence   exchanged,   to   arrive   at   the   real

intendment of the parties, and not what one of the parties may

contend subsequently to have been the intendment or to say

20

as included afterwards, as observed in Bank of India & Anr.

vs. K. Mohandas & Ors., (2009) 5 SCC 313:

“28. The true construction of a contract must

depend upon the import of the words used and

not   upon   what   the   parties   choose   to   say

afterwards. Nor does subsequent conduct of

the parties in the performance of the contract

affect   the   true   effect   of   the   clear   and

unambiguous words used in the contract. The

intention of the parties must be ascertained

from the language they have used, considered

in the light of the surrounding circumstances

and the object of the contract. The nature and

purpose of the contract is an important guide

in ascertaining the intention of the parties.”

21. The   respondent’s   letters   dated   07.08.2012   and

27.08.2012 become crucially relevant for the understanding

that it was itself under no misapprehension that RLNG was

never intended to be included within the definition of natural

gas under the contract. In the former, the respondent wrote,

“We await the confirmation from your good office to take it up

further for obtaining necessary consent, if any, in accordance

with law for use of RLNG and the resultant tariff increase.”

The latter again requested for permission to use RLNG to

21

supplement shortfall in gas from the KG­D6 Basin, requesting

to acknowledge its usage. The contention of the respondent

that   these   were   only   intimations   and   not   request   for

permission to use RLNG stands belied from the plain language

used in them.   The appellant in its reply dated 10.09.2012

explicitly stated that under the agreement no other fuel except

natural   gas   could   be   used   and   that   RLNG   was   never

contemplated in the definition of fuel declining to accept the

spot supply agreement for RLNG supplies, citing the cost of

power per unit from the same at Rs.9­10 in comparison to

Rs.3/­ per unit from natural gas.   It is only thereafter the

respondent approached the Commission in OP No.20 of 2013.

The pleadings of the respondent, as quoted hereinafter, further

confirm its own understanding that RLNG was never intended

to be included in the definition of fuel which was confined to

natural gas only :­

“9.   Since   the   above   scenario   affects   the

generation   activities   of   the   Petitioner,   the

Petitioner   proposed   to   use   RLNG.     In   this

respect,   the   Petitioner   has   already   made

representations to the Respondent Nos. 2 and 3

22

vide its letters dated 7.8.2012 and 27.8.2012

(produced   as   Annexures   P­2   and   P­3

respectively).     In   both   these   letters,   the

Petitioner appealed to the said Respondents to

allow  usage  of  RLNG  and  substantiated  the

circumstances/reasons for the said request of

the petitioner.

10.To   the   utter   surprise   and   shock   of  the

Petitioner,   instead   of   acceding   to   the   above

requests of the Petitioner, the Respondent No.3

has   rejected   the   above   requested   of   the

Petitioner vide its letter dated 10.09.2012.”

22.The sporadic use of RLNG on one or two occasions under

pressing circumstances, after due orders under Section 11 of

the Electricity Act, 2003, for short durations, cannot make the

exception the norm to contend either that RLNG was included

in the term fuel or that the appellant had agreed to its use.

The question of waiver by the appellant or application of the

principle of approbate and reprobate does not arise in the facts

of the case.

23.The   present   was   a   contract   for   purchase   of   power

generated from fuel which was reasonably priced so as to keep

23

in check the cost of power generated from the same, in the

interest of the consumer.   Undoubtedly, cost of fuel was a

primary   consideration   in   the   mind   of   the   appellant.     The

contextual background in which the PPA originally came to be

made, the subsequent amendments, the understanding of the

respondent   of   the   agreement   as   reflected   from   its   own

communications   and   pleadings   make   it   extremely   relevant

that   a   contextual   interpretation   be   given   to   the   question

whether RLNG was ever intended to be included within the

term “Natural Gas”, as observed in Bihar State Electricity

Board vs. Green Rubber Industries, (1990) 1 SCC 731:

“23…. Every contract is to be considered with

reference to its object  and  the whole  of its

terms and accordingly the whole context must

be considered in endeavouring to collect the

intention   of   the   parties,   even   though   the

immediate object of enquiry is the meaning of

an isolated clause….”

24.In the facts and circumstances of the present case, there

can be no manner of doubt that the parties by their conduct

and dealings right up to the institution of proceedings by the

respondent   before   the   Commission   were   clear   in   their

24

understanding that RLNG was not to be included within the

term   “Natural   Gas”   under   the   PPA.   The   observations   in

Gedela   Satchidananda   Murthy   (supra)  are   considered

apposite in the facts of the present case :­

“32…The principle on which Miss Rich relies is

that   formulated   by   Lord   Denning,   M.R.   in

Amalgamated Investment & Property Co. Ltd.

v.   Texas­Commerce   International   Bank   Ltd.,

[1982] 1 QB at p.121: 

‘If parties to a contract, by their course

of dealing, put a particular interpretation on

the terms of it—on the faith of which each of

them—to the knowledge of the other—acts

and conducts their mutual affairs—they are

bound by that interpretation just as much

as if they had written it down as being a

variation of the contract. There is no need to

inquire   whether   their   particular

interpretation is correct or not—or whether

they were mistaken or not—or whether they

had   in   mind   the   original   terms   or   not.

Suffice it that they have, by their course of

dealing,   put   their   own   interpretation   on

their contract, and cannot be allowed to go

back on it.’ 

(emphasis supplied)"

25.A   commercial   document   cannot   be   interpreted   in   a

manner   to   arrive   at   a   complete   variance   with   what   may

25

originally have been the intendment of the parties. Such a

situation can only be contemplated when the implied term can

be considered necessary to lend efficacy to the terms of the

contract. If the contract is capable of interpretation on its

plain meaning with regard to the true intention of the parties

it   will   not   be   prudent   to   read   implied   terms   on   the

understanding of a party, or by the court, with regard to

business efficacy as observed in Satya Jain (D) thr. Lrs. &

Ors. vs. Anis Ahmed Rushdie (D) thr. Lrs. & Ors. , (2013) 8

SCC 131, as follows:­ 

“33.The   principle   of   business   efficacy   is

normally   invoked   to   read   a   term   in   an

agreement   or contract  so as  to achieve  the

result   or   the   consequence   intended   by   the

parties   acting   as   prudent   businessmen.

Business efficacy means the power to produce

intended results. The classic test of business

efficacy   was   proposed   by   Lord   Justice

Bowen,L.J.   in   Moorcock.   This   test   requires

that   a   term   can   only   be   implied   if   it   is

necessary   to   give   business   efficacy   to   the

contract   to   avoid   such   a   failure   of

consideration   that   the   parties   cannot   as

reasonable  businessmen  have   intended.  But

only   the   most   limited   term   should   then   be

implied–the   bare   minimum   to   achieve   this

goal.   If   the   contract   makes   business   sense

26

without the term, the courts will not imply the

same. The following passage from the opinion

of Bowen, L.J. in the Moorcock (supra) sums

up the position: (PD p.68)

“…In business transactions such

as this, what the law desires to effect by

the implication is to give such business

efficacy to the transaction as must have

been   intended   at   all   events   by   both

parties who are business men; not to

impose on one side all the perils of the

transaction, or to emancipate one side

from all the chances of failure, but to

make   each   party   promise   in   law   as

much, at all events, as it must have

been   in   the   contemplation   of   both

parties that he should be responsible

for   in   respect   of   those   perils   or

chances.”

34.Though in an entirely different context,

this court in United India Insurance Co. Ltd. v.

Manubhai Dharamasinhbhai Gajera and Ors.

had   considered   the   circumstances   when

reading an unexpressed term in an agreement

would be justified on the basis that such a

term was always and obviously intended by

and   between   the   parties   thereto.   Certain

observations   in   this   regard   expressed   by

Courts   in   some   foreign   jurisdictions   were

noticed by this court in Para 51 of the report.

As   the   same   may   have   application   to   the

present case it would be useful to notice the

said observations :(SCC p.434)

“51. …’…”Prima facie that which in any

contract is left to be implied and need

not   be   expressed   is   something   so

obvious that it goes without saying; so

27

that, if, while the parties were making

their   bargain,   an   officious   bystander,

were to suggest some express provision

for   it   in   their   agreement,   they   would

testily   suppress   him   with   a   common

‘Oh, of course!’ ‘’ Shirlaw v. Southern

Foundries (1926) Ltd., KB p.227.’

** *

“An expressed term can be implied if and

only if the court finds that the parties

must have intended that term to form part

of their contract: it is not enough for the

court to find that such a term would have

been   adopted   by   the   parties   as

reasonable men if it had been suggested

to them: it must have been a term that

went without saying, a term necessary to

give business efficacy to the contract, a

term which, although tacit, formed part of

the contract which the parties made for

themselves.   Trollope   and   Colls   Ltd.   v.

North   West   Metropolitan   Regl.   Hospital

Board, All ER p.268a­b.’ ”

35.   The   business   efficacy   test,   therefore,

should be applied only in cases where the

term that is sought to be read as implied is

such   which   could   have   been   clearly

intended   by   the   parties   at   the   time   of

making of the agreement...”

26. The definition of natural gas in Section 2(za)(i) of the

PNGRB Act, has no relevance to the present controversy as the

28

Act   was   enacted   with   the   object   to   oversee   and   regulate

refining, processing, distribution and marketing of petroleum

products and natural gas.  Similarly, the observation made in

Association   of   Natural   Gas  (supra)   in   context   of   the

controversy with regard to legislative entry has no relevance to

the interpretation of the PPA. 

27.The   aforesaid   discussion,   therefore,   leads   to   the

inevitable conclusion that the intention of the parties under

the agreement, as amended from time to time, was to generate

power from fuel reasonably priced, so as to ultimately make

available power to the consumers at reasonable rates. The

choice   of   fuel   as   natural   gas   only   has,   therefore,   to   be

understood as being confined to natural gas only in its natural

form. The respondent was well aware that RLNG was never

intended to be included in the definition of natural gas as

understood by the parties, notwithstanding that it may be a

variant of natural gas.

29

28.The appeal, therefore, has to be allowed, the Appellate

Tribunal   judgment   is  reversed,   and  the   Commission  order

dated 08.08.2013 is affirmed.
