COMMON JUDGMENT
Prelude:
M/s GAIL (India) Limited, a Public Sector undertaking under the administrative control of Government of India, Ministry of Petroleum & Natural Gas (in short ‘MoP & NG’) involved in distribution and sale of Natural Gas. According to the Government policy, based on the end use and region of supply (landfall point) the pricing of the Gas determined by the Government of India. The role of MoP & NG is to distribute natural gas at the price fixed under the pricing policy to the companies, which were in need of natural gas. Earlier, (i.e.) from 18.09.1997, the price of gas fixed based on the landfall points linked to the price of a basket LS/HS fuel granting concession price for the North-Eastern States. The price was determined and notified by M/s GAIL (India) Limited with the approval of MoP & NG, every quarter. Parties willing to buy natural gas from M/s GAIL (India) Limited, has to enter into Gas Supply Contract (GSC) with M/s GAIL (India) Limited.7/46
https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm )
2. M/s Arkay Energy (Rameswaram) Limited; M/s Coromandel Electric Co. Ltd.; M/s Sahell Exports Pvt. Ltd.; M/s Kaveri Gas Power Ltd.; and M/s OPG Energy Pvt. Ltd. are the five companies, which had entered into Gas Supply Contract (in short “GSC”) with M/s GAIL (India) Limited, on different dates and were procuring gas at the price fixed in terms of Article 10 of the GSC. Further, M/s GAIL (India) Limited as Seller and transporter and the procuring companies as BUYER, for the sale and purchase/transmission of Natural Gas, have entered into Gas Sales and Transmission Agreement (in short “GSTA”) to deal about the manner of deliver, measurement and calibration, billing and payments, price, transmission and marketing cost etc.,
3. While so, the Government of India, took a policy decision to dismantle The Administrated Price Mechanism (in short “APM”) in a phased manner and to restrict the concession price under APM only for the manufacturers of fertilizer and for power generating companies. As a result, on 20.06.2005 in super session of earlier order, Ministry of Petroleum and Natural Gas ( MoP & NG) fixed Rs.3,200/-per SCMD as APM price and 8/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) Rs.3,840/- per SCMD as non-APM price. Buyers were intimated about the change in pricing policy and APM price fixed for the year 2005-2006 with effect from 06.06.2006. Buyers were called upon to confirm whether they fall within the category of Fertilizer or Power Generators. On the request of M/s GAIL (India) Limited, a classificatory letter, dated 27.06.2006, sent by MoP & NG to M/s GAIL (India) Limited, stating that APM gas price would be applicable for only those quantities of gas, which are used for generating electricity, which is supplied to the grid for distribution to the consumers through the public/utilities/licensed distribution companies.
4. For the above mentioned five buyer companies, M/s GAIL (India) Limited, after getting confirmation from them that they are using the gas supplied only for power generation and the same is distributed through grid for consumers, supplied natural gas at concessional APM price of Rs.3,200/- per SCMD. However, during the audit by CAG in the year 2011, it was found that natural gas from Cauvery Basin were supplied at APM price for the companies, which do not fulfil the condition of distributing through grid to the consumers through public utilities/licensed distribution companies. They either utilised the power generated without supplying to the 9/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) grid or sold it to captive consumers using wheeling arrangement with the State Electricity Board. Awaiting clarification, the natural gas supplied at APM price, on provisional basis, was found to be erroneous. It was reported that supply of gas under APM rates to non-eligible customers in violation of the Ministry’s order had resulted in loss of revenue to the tune of Rs.246.16 crores in the Gas Pool Account during April 2006 to March 2011. This Report of CAG triggered MoP & NG to write to M/s GAIL (India) Limited, on 17.11.2011 for action to recover the dues from the respective customers. In response, M/s GAIL (India) Limited through its General Manager (Marketing) vide, letter dated 02.11.2011 had informed the Ministry that they are taking action for invoicing at market price with effect from 16.11.2011 and also raising debit notes for the period prior to 16.11.2011. When the debit notes raised by the M/s GAIL (India) Limited for the differential rate between the market price and the APM price, the buyer companies disputed the claim and invoked the arbitration clause for settlement of the dispute.

O.S.A.(CAD)No.42 of 2021 and O.S.A.No.64 of 2021:
25. O.S.A.No.42 of 2021 and O.S.A.No.64 of 2021 by M/s GAIL (India) Limited against the order passed by the learned Single Judge in O.P.No.696 of 2016 and O.P.No.526 of 2016 respectively, along with C.M.P.Nos.13808 of 2024 and 13807 of 2024 to permit the appellant to raise additional ground were filed. In these two appeals and petitions, M/s Kaveri Gas Power Ltd. is the respondent.
26. Before adverting to the merits of the appeals under consideration, it is appropriate to record the memo filed on behalf of M/s Kaveri Gas Power Ltd on 19.07.2024. In this memo, it is reported that pending O.S.A.(CAD)No.42 of 2021 and O.S.A.No.64 of 2021, NCLT, Chennai vide order dated 04.02.2022 commenced Corporate Insolvency Resolution Process (CIRP) against M/s Kaveri Gas Power Ltd. and moratorium was imposed with effect from 04.02.2022. Thereafter, Interim 20/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) Resolution Professional and subsequently, Resolution Professional appointed. The Resolution Plan proposed by RP failed leading to passing of liquidation order on 09.12.2022. M/s Kaveri Gas Power Ltd was purchased by one S.Elangovan in the auction. The liquidation auction sale was approved by NCLT vide order dated 26.04.2024. In the liquidation sale approval order, NCLT has recorded that all claims and obligation against M/s Kaveri Gas Power Ltd. stands discharged. Thereafter, the liquidation process closed formally vide, order dated 10.05.2024. Thus, M/s GAIL (India) Limited, which has not participated in the liquidation process, has lost its right to make any claim against M/s Kaveri Gas Power Ltd. Hence, the appeals stands abated.
27. Mr.Vinod Kumar, the Learned Counsel representing M/s Kaveri Gas Power Ltd., relying on the judgement of the Hon'ble Supreme Court rendered in Ghanashyam Mishra and Sons (P) Ltd -vs- Edelweiss Asset Reconstruction Company Ltd reported in [(2021) 9 SCC 657], submitted that the 'clean slate theory' propounded in the above case squarely applies to M/s Kaveri Gas Power Ltd., hence, nothing survives in the appeal arising from the Arbitral Award passed against M/s Kaveri Gas Power Ltd. 21/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm )
28. No specific denial or rebuttal to the above submission made by Learned Counsel, received from M/s GAIL (India) Limited.
Grounds of Appeal, Arguments and findings:
Submission on behalf of M/s GAIL (India) Ltd:
29. On behalf of M/s GAIL (India) Limited, the learned Senior Counsels Mr.P.V.S.Giridhar, Mr.M.Ajmal Khan and Mr.P.Wilson, appeared and placed their arguments under five broad heads.
30. They submitted that the buyers, who are the power generators using the natural gas supplied by M/s GAIL (India) Limited, utilised the power generated by them for private sale to its captive consumers. They did not supply power to the general public. Therefore, they are not entitled for APM price. It is contended that the power generated by them using the gas supplied by M/s GAIL (India) Limited was distributed to their own captive consumers through the wheeling arrangement paying wheeling charges to TANGEDCO. Such customers of M/s GAIL (India)Limited are not entitled for APM price, since they do not fall within the purview of distribution to 22/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) consumers through a public utility/licensed distribution company.
(i)The MoP & NG, while classifying consumers under four categories, clarified that consumers generating electricity and supplying it to various consumers through the wheeling company arrangement with the State Electricity Board are not entitled for APM price.
(ii) Natural Gas is a resources vested with the Government of India. M/s GAIL (India) Limited has been distributing and selling the natural gas as Trustee. Till the resource reaches the end consumer, M/s GAIL (India) Limited, deals with the natural gas as a custodian and trustee of a public resources. When public trust doctrine applies, the plea of waiver, acquiescence or estoppel will not arise. The learned Single Judge without taking note of the spirit behind Section 10 and Section 17 of the Limitation Act, 1963, erred in holding that M/s GAIL (India) Limited is not entitled to claim the differential rate between APM price and Non-APM price, since the claim is barred by limitation and hit by waiver, acquiescence or estoppel,
(iii)Article 10 with the caption “Price of Gas Supply Contract (GSC) / Gas Sales and Transmission Contract (GSTC)”, empowers the Central Government/ MoP & NG to fix the price of natural gas. Buyers on express acceptance of the said condition, had purchased the natural gas 23/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) subject to the terms and conditions contemplated under GSC/GSTC. The supply of natural gas at APM-price to the respondent companies was only on a provisional basis, pending clarification from MoP & NG. While so, the learned Single Judge ought not to have invoked the principles of estoppel or acquiescence to deny the lawful claim of M/s GAIL (India) Limited to recover the differential charges.
(iv)The respondents, by misrepresenting the nature of their business and utilisation of the energy generated from the gas supplied by Grid, derived an unfair benefit and cannot be permitted to be unjustly enriched by such misrepresentation. The benefit was extended to the respondent companies solely based on their misrepresentation. Since it was a mistake, the time, till the discovery of the misrepresentation has to be excluded under Section 17 of the Limitation Act, 1963. The circular dated 20.06.2005 followed by the clarification dated 27.06.2006 issued by the MoP & NG, beyond any doubt excludes power generators utilising power for captive consumers from getting the benefit of APM price. The debit note was issued only in respect of the differential price that has been erroneously extended to the respondent companies due to mistake and misrepresentation. Hence, the decision of the learned Single Judge, denying the lawful claim of 24/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) M/s GAIL (India) Limited, on the ground of limitation and estoppel, is perverse and against settled legal principles and against public policy.
(v)On behalf of the Government M/s GAIL (India) Limited holds natural resources in trust. The natural gas in question is held for the specific purpose of developing such resources in the interest of the people. Therefore, M/s GAIL (India) Limited, which is only a marketing agent for the transaction of public resources to power generators, holds the said natural resources vested in it in the capacity of a trustee. Therefore, under Section 10 of the Limitation Act, 1963, there is no limitation prescribed for the properties held by trustees. The Learned Single Judge miserably failed to apply Section 10 of Limitation Act, 1963 which specifically excluded limitation on enforcing the liability of the respondents. In Reliance Natural Resources Ltd. v. Reliance Industries Ltd., reported in [(2010) 7 SCC 1], the Hon'ble Supreme Court has held that supply of a natural resources, like, gas is governed by the public trust doctrine. Therefore, the relationship between M/s GAIL (India) Limited and the respondents not governed solely by contractual obligations, but is also governed by trust and public trust principles. Under Section 10 of the Limitation Act, 1963, three years period prescribes under Article 15 for the recovery of price of the goods sold and 25/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) delivered, is not applicable. In this regard, M/s GAIL (India) Limited is also taken out a petition under Order II, Rule (4) and Rule (22) of the OS Rules of Madras High Court to permit the appellant M/s GAIL (India) Limited to raise additional ground.
31. In nutshell, the contention of M/s GAIL (India) Limited is that they are holding the natural gas as trustee on behalf of the Government of India representing the people. Therefore, even by the contractual agreement, the right to claim the due price of the natural resources neither be waived nor estopped. As a marketing agent, M/s GAIL (India) Limited, distributes natural gas at the price fixed by the MoP & NG. The actions of M/s GAIL (India) Limited cannot curtail the right of the Government claiming the differential price extended to the respondents by mistake, by misrepresentation or by fraud. For reckoning limitation, till the period upto CAG report dated 16.09.2011, it has to be excluded in view of mutual mistake, invoking Section 17 of the Limitation Act, 1963.
32. The Learned Senior Counsels representing M/s GAIL (India) Limited submitted that the claim of M/s GAIL (India) Limited cannot be 26/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) termed as a counter claim. In fact, it is a fresh claim made after the mistake and misrepresentation came to the knowledge of the supplier viz M/s GAIL (India) Limited. The concession price under APM rate extended to the respondents, by mistake, misrepresentation or fraud, sought to be recovered through the debit notes. However, the learned Single Judge has described the action of M/s GAIL (India) Limited as a 'counter-claim'. This error has led to the erroneous conclusion that the debit notes raised by M/s GAIL (India) Limited is hit by estoppel/acquiescence or barred by limitation. Even though fraud or misrepresentation was not expressly pleaded before the Arbitrator, the plea of 'mistake' is sufficient to save the limitation, since the issue involves public money and a concession was extended without authority of law. The differential price can be recovered without any reference to the Limitation Act, 1963 by applying the public trust doctrine.
33. The learned Senior Counsels representing M/s GAIL (India) Limited, to buttress their arguments had relied upon the following judgments:
(i)Chandi Prasad Uniyal v. State of Uttarkhand (2012)8 SCC 417;
(ii)Mahabir Kishore v. State of M.P [(1989) 4 SCC 1];27/46
https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm )
(iii)Mahindra Holidays and Resort v. State of Kerala [(2019) 3 KLJ 166];
(iv)Essar Steel Ltd. v. Union of India [2005 SCC Online Guj. 194];
and
(v)Reliance Natural Resources Ltd., vs. Reliance Industries Ltd., [(2010) 7 SCC 1].
34. Submission on behalf of M/s Arkay (Rameswaram) Limited, M/s Coromandel Electric Co. Ltd., M/s OPG Energy Pvt. Ltd. and M/s Kaveri Gas Power Ltd.:
Mr.P.S.Raman, learned Senior Counsel representing for Mr.K.Harishankar appearing for M/s Coromandel Electric Co Ltd submitted that the appellant namely, M/s GAIL (India) Limited, from 2005 to 2011 was supplying natural gas at APM rate, after confirming that the respondents are power generators and distributing the power through Grid for the utilisation of consumers. Only because of the audit objection raised by the CAG in the year 2011, for the first time they sub-classified the power generators as those distributing power through Grid for utilisation by public consumer and for utilisation by captive consumer. The respondents, being the power 28/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) generators, hold agreement with TNEB for wheeling the power and had paid necessary charges for such wheeling. The power is utilised by captive customers. Prior to CAG objection and communication, M/s GAIL (India) Limited or MoP & NG never classified the customers as public or captive customers. The respondents had entered into GSC/GSTC with M/s GAIL (India) Limited on the specific term that the power generated by these respondents to be pooled through Grid for utilisation by the end users who are the captive customers of the power generators. M/s GAIL (India) Limited, consciously fixed the APM price after satisfaction on the clarification given by the respondents about the end users of the power generated. From June 2006, natural gas was sold by M/s GAIL (India) Limited at APM rate. Using the natural gas supplied by M/s GAIL (India) Limited, power generated and distributed through the grid for the consumers.
Till the CAG communication dated 16.09.2011, there was no differential classification between the captive consumers and general consumers.
35. Mr. P.S.Raman, learned Senior Counsel submitted that the difference among the customers has no reasonable justification. Like, public customers, the captive customers also otherwise only depend on the public 29/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) power supply. By purchasing power from power generators through wheeling, the respondents in fact reduce the burden of the State supplying power to them. Therefore, the respondents, who are admittedly generating the power using the gas supplied and distributing it through Grid, cannot be mulcted with non-APM price with retrospective effect. M/s GAIL (India) Limited belated claim that supply of natural gas at APM price was a mistake due to misrepresentation is incorrect and untenable. The contract between M/s GAIL (India) Limited and the respondents is purely governed by the principles of contract. M/s GAIL (India) Limited cannot claim any privilege or advantage in respect of limitation by introducing plea of public trust doctrine. Natural gas sold by M/s GAIL (India) Limited, as a distributor and purchased by the respondents for the price quoted, will not fall within the principles of public trust doctrine. Section 10 of Limitation Act, 1963 does not apply to the facts of the case. A plea not raised before the Arbitrator or before the learned Single Judge, is now sought to be introduced by filing petitions to receive additional grounds. The learned Single Judge has dealt with the said plea made orally during arguments and has rightly rejected it. Therefore, the petitions to receive additional grounds is to be dismissed as redundant and superfluous.
30/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm )
36. Mr.Aniruth Krishnan, learned counsel and Mr.Adarsh Subramaniam, learned Counsel appearing for M/s Arkay (Rameswaram) Limited, submitted that there was no fraud, misrepresentation or mistake on the part of the respondents. Neither was there any unjust enrichment by them in availing of the APM price for the natural gas. The natural gas supplied were converted into energy, as per the agreement and the energy sold to the customers through grid. The pricing policy, as found in the communication dated 05.06.2006 and the further clarification by the Government of India, vide letter dated 27.06.2006, makes very clear that APM gas price is applicable for those quantity of gas used for generating electricity which is supplied to the Grid for distribution to customers through public utilities or licensed distribution companies. Based on this clarification, M/s GAIL (India) Limited and the respondents continued the contract of supply and purchase of natural gas at the price fixed. The power generated by these respondents had been sold to their respective customers taking into account the supply price of the natural gas fixed by M/s GAIL (India) Limited. The allegation by M/s GAIL (India) Limited that the purchaser companies mis- represented to them is false and untenable.
31/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm )
37. The debit notes issued by M/s GAIL (India) Limited, demanding a higher price for goods already sold and utilized, will not fall under the public trust doctrine, since neither M/s GAIL (India) Limited, nor the respondents holding the natural resources. After supply of the energy to the end users several years ago, the plea of public trust doctrine or mistake under Section 17 of Limitation Act, 1963 and also to hold M/s GAIL (India) Limited as Trustee under Section 10 of the Limitation Act, 1963 is baseless and preposterous. These plea are desperate attempt by M/s GAIL (India) Limited to get protection under Limitation Act,1963 and justify their belated claim with retrospective effect. Further, the Learned Counsels appearing for the respondents contended that the defence, which were not raised before the Arbitrator, is raised by the appellant for the first time, in the Court. Power of the Court under Section 34 as well as Section 37 of the Arbitration and Conciliation Act, 1996 are very limited. The grounds raised in the appeal filed by M/s GAIL (India) Limited does not fall within the parameters laid by the Hon'ble Supreme Court regarding the scope and ambit of Section 34 and 37 of Arbitration and Conciliation Act, 1996.
32/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm )
38. Heard the Learned Counsels appearing on either side. The written submission filed by them carefully considered.
39. In respect of sale of natural gas, till 2005, the Government Pricing Order dated 01.10.1997 was in vogue. After change in policy, the Ministry of Petroleum and Natural Gas came out with revision of APM gas prices for consumers other than power and fertilizer sector consumers and communicated it to the stakeholders like M/s GAIL (India) Limited, ONGC Limited and Oil India Limited through letter dated 05.06.2006.
40. The said letter reads as below:-
“ 1. Please refer to this Ministry's letter of even number dated 20.06.2005 regarding Allocation and Pricing of Natural Gas. The said Order envisages revision of APM gas prices for consumers other than power and fertilizer sector consumers, in a phased manner over next 3-5 years to reflect the market price. In pursuance to the said decision of the Government, it has been now decided to increase the price of APM gas being supplied to the City Gas Distribution Projects and small consumers having allocations upto 33/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) 0.05 MMSCMD by 20% over the current APM price of Rs.3200/MSCm for general consumers and Rs.1020/MSC for North-East consumer. Thus, the revised prices for the above categories of consumers would be Rs.3840/MSCM for general consumers and Rs.2304/MSCm for North-East consumers.
2. Further, GAIL shall charge market price for the quantity of gas supplied to IGL and MGL which they are marketing to industrial consumers at market price. However, this increase in the gas price will not impact the Industrial consumers of IGL and MGL as they are already being charged market price for gas supplied to them.
3.This Order will come into effect from the mid-night of 5th /6th June 2006.”
41. The pricing policy for the supply of natural gas always been the prerogative of the Government. The terms of contract between the supplier (M/s GAIL (India) Limited) and its customers (power generating companies) deals with the pricing of Natural gas distributed through M/s GAIL (India) Limited. The most relevant clause in the said GAS SUPPLY CONTRACT ( GSC) is Article 10.01, which reads as below:-
34/46
https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) Article-10 Price of Gas:
10.01 Present price of 1000 (One Thousand) Standard Cubic meters of GAS w.e.f 01.10.1997 is applicable as per Government Pricing Order No.L-12015/3/94-GP dated 18.09.1997 (Annexure-III). After 31.03.2000 the SELLER shall have right to fix the price of GAS which may be as per directive, instruction, order, etc. of the Government of India etc. which is likely to be market related in accordance with current policy of liberalization of the Government of India and the BUYER shall pay to the SELLER such price of GAS. Provided further, the price of GAS so fixed is exclusive of Royalty, Taxes, Duties,Service/ Transportation (Transmission) charges and all other statutory levies as applicable at present or to be levied in future by the Central or State Government or Municipality or any other local body or bodies payable on purchase of GAS from ONGCL/Other Producer(s) by the SELLER or on sale from SELLER to the BUYER and these shall be borne by the BUYER over and above the aforesaid price.
42. So long, GAIL the appellant supplying natural gas at APM price to the power generators/the respondents on the representation of the respondents regarding the end user of the power generated by them. The 35/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) contention of the CAG in its audit report is that the power generators supply Electricity to their customers at commercial rate through the Grid of Tamil Nadu Electricity Board thereby they are gaining undue benefit. For such purchase to that extent, deprive consumers eligible for APM price. In this communication, CAG has stated that the company while implementing the Government directives had segregated its gas consumers in Cauvery Basin under Four categories viz., Category A -State Electricity Boards and Government Companies generating power for supply of Grid for distribution to consumers.
Category B – Private Companies generating power and selling to State Boards as IPP;
Category C – Consumers generating electricity for captive consumption without supplying to GRID and Category D- Consumers generating electricity and supplying to various consumers using wheeling arrangement with state Electricity Boards. When clarification sought from the Ministry by the companies, whether D consumers were entitled for APM price, the Ministry has given the required clarification. There was no ambiguity in the Ministry's directives regarding applicability of APM gas price to customers generating power for supply to 36/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) the Grid for distribution through public utilities/licensed distribution companies only. Therefore M/s GAIL ought not to have supplied natural gas at APM rate to the category D consumers who are supplying power at commercially agreed rates in India.
43. We find, no such detail clarification with four categories of consumers had emanated from MoP & NG at any point of time prior to the CAG communication. The terms in the Gas Supply Contract (GSC) or in the Gas Sale and Transmission Agreement (GSTA) or in the clarificatory letters of MoP & GC, we are not able to find the four categories of consumers mentioned in the CAG report. While so, the contention of CAG that there was no ambiguity in the clarification given by MoP & NG is per se incorrect. When there was no sub classifications of consumers in the pricing policy dated 06.06.2006 or in the clarificatory letters, alleging that the power generating companies by misrepresentation or by fraud availed APM price and thereby, got unjust enrichment is totally untenable.
44. In Indian Council for Enviro-Legal Action v. Union of India and others reported in [(2011) 8 SCC 161], the Hon’ble Supreme Court has 37/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) explained, what is unjust enrichment, which reads as below:
“159. Unjust enrichment is basic to the subject of restitution, and is indeed approached as a fundamental principle thereof. They are usually linked together, and restitution is frequently based upon the theory of unjust enrichment. However, although unjust enrichment is often referred to or regarded as a ground for restitution, it is perhaps more accurate to regard it as a prerequisite, for usually there can be no restitution without unjust enrichment. It is defined as the unjust retention of a benefit to the loss of another or the retention of money or property of another against the fundamental principles of justice or equity and good conscience. A person is enriched if he has received a benefit, and he is unjustly enriched if retention of the benefit would be unjust. Unjust enrichment of a person occurs when he has and retains money or benefits which in justice and equity belong to another.”
45. In Chandi Prasad Uniyal and others v. State of Uttarakhand and others reported in [(2012) 8 SCC 417], the Hon'ble Supreme Court has observed as below:
“14.We are concerned with the excess payment of public money which is often described as 38/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) “taxpayers”money” which belongs neither to the officers who have effected overpayment nor to the recipients. We fail tos ee why the concept of fraud or misrepresentation is being brought in such situations. The question to be asked is whether excess money has been paid or not, may be due to a bona fide mistake. Possibly, effecting excess payment of public money by the government officers may be due to various reasons like negligence, carelessness, collusion, favouritism, etc., because money in such situation does not belong to the payer or the payee. Situations may also arise where both the payer and the payee are at fault, then the mistake is mutual. Payments are being effected in many situations without any authority of law and payments have been received by the recipients also without any authority of law. Any amount paid/received without the authority of law can always be recovered barring few exceptions of extreme hardships but not as a matter of right, in such situations law implies an obligation on the payee to repay the money, otherwise it would amount to unjust enrichment.”
46. In the given case, though CAG has said that the clarification of Ministry is without any ambiguity, the Appellant/ M/s GAIL (India) Limited, ever since the price revision in the month of June 2006 had never placed on 39/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) record that they have categorised their consumers under four categories such as A, B, C and D as found in the CAG letter. Contrarily, the communication of M/s GAIL (India) Limited to the respondents shows that they were supplying gas for producing electricity with full knowledge that their customers, who are generating power using the natural gas, are distributing the power through Grid for utilization of its captive consumers.
47. No doubt, the captive consumers of these power generators had the advantage of fixing the price by negotiation with the power generators and the power sold by the these respondents was at commercial price. However, when the pricing policy fixing APM gas price for generating electricity which is supplied to the Grid for distribution to the consumers through the public utilities/licensed distribution companies explicitly clarified by the Ministry of Petroleum and Natural Gas, vide, letter dated 27.06.2006, using the same expression without any difference between captive consumer and the public consumer, it is beyond any comprehension to entertain the sub classification of the consumer as public consumer and captive consumer at a later point of time. The learned Single Judge has therefore rightly held that M/s GAIL (India) Limited is estopped to make a 40/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) sub-classification of the consumers for depriving the concession already granted and acted upon by the parties based on the promise. For easy reference, the content of the clarification letter of MoP & NG is extracted below:-
“ Subject: Revision of APM gas price w.e.f 06.06.2006. Sir, I am directed to refer to GAIL's letter No.ND/GAIL/Pricing/2006 dated 12th June 2006 on the above subject and to say that GAIL should charge market price for those quantities of APM gas being supplied by them to the City gas distribution companies, which the latter are using for supplying gas to the industrial and commercial consumers at market price. As these industrial and commercial consumers are already paying the market price to the city gas distribution companies, the increase in input gas price by GAIL would have no price impact on such consumers.
APM gas price would be applicable for only those quantities of gas which are used for generating electricity which is supplied to the grid for distribution to the consumers through the public utilities/licensed distribution companies.
GAIL is request to take necessary action accordingly.” 41/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm )
48. Therefore, the plea of unjust enrichment, if to be considered in the light of the above judgments cited supra, this Court finds that there is no unjust enrichment for the respondents who have generated energy and sold to its customers for the price fixed. Neither the plea of mistake to apply section 17 of the Limitation Act, 1963 to save limitation can be countenanced.
49. M/s GAIL (India) Limited, claims to be a distributor. It is in direct contact with the respondent with whom they have entered into written agreement regarding the supply, pricing, distribution and utilisation. M/s GAIL (India) Limited was never oblivious of the fact that the power generated by the respondents were distributed under wheeling arrangement and the end users are their captive customers. The plea of public trust doctrine exposed in Reliance Natural Resources Ltd., v. Reliance Industries Ltd., reported in [(2010) 7 SCC 1], will not apply to the case in hand, since the resources sold for a price fixed, after due deliberation. It is not the case of M/s GAIL (India) Limited that the natural gas not utilised for power generation or it was not distributed through grid. Their specific case is that the power generated sold to the captive consumers and not to the public consumers. A concluded contract with ad idem, cannot be reopened by 42/46 https://www.mhc.tn.gov.in/judis ( Uploaded on: 24/10/2025 06:19:47 pm ) supplying terms externally, which are not part of the contract or in the clarificatory letters.
50. The extent of power generated by the respondents already utilized by distribution through grid for its customers. For the first time, after CAG objection, M/s GAIL (India) Limited claims that the customers must be general public and not captive customers. This differentiation never propounded by M/s GAIL (India) Limited in the terms of contract. For the first time, after CAG report dated 16.09.2011, debit notes raised for the differential price. By the time, the natural gas sold by M/s GAIL (India) Limited converted into energy by the contesting companies and sold to its consumers. Hence, even public trust doctrine will not apply to the case in hand, when there is a transparent transaction of the natural resources based on the terms of the contract. The sale of the Goods Act, 1930 does not provide for claiming higher price retrospectively after completion of the transaction at a specific price. If the plea of M/s GAIL (India) Limited, for any reason entertained, it will lead to uncertainty in perpetuity, which is against public policy.43/46

51. The learned Single Judge, after due consideration of the facts, had rightly held that M/s GAIL (India) Limited, cannot claim any differential price with retrospective effect. Their right to claim non-APM price from the power generators, who are not supplying the power to the general public not entitled for APM price, will apply only prospectively and such change of policy is permissible under Article 10 of the Gas Supply Contract.
52. In the light of the above discussion, we hold that these appeals preferred against the well considered Common Order of the learned Single Judge deserved to be dismissed.
53. Accordingly, O.S.A.No.300 of 2020, O.S.A.(CAD)No.42 of 2021, O.S.A.No.64 of 2021, O.S.A.(CAD)No.109 of 2021, O.S.A.(CAD)No.125 of 2021 and O.S.A.(CAD)No.127 of 2021 all filed by M/s GAIL (India) Limited stand dismissed. O.S.A.(CAD)No.66 of 2022 filed by M/s Arkay Energy (Rameswaram) Limited also stands dismissed.44/46

54. The Civil Miscellaneous Petitions to receive additional ground have been considered both by the learned Single Judge as well as by this Court. Hence, no separate order is required in these Petitions.
Consequentially, the other Miscellaneous Petitions for stay of operation of the Common Order of the learned Single Judge are closed.
55. In the result, all OSAs and CMPs are dismissed. No order as to costs.
