PETROLEUM & NATURAL GAS REGULATORY BOARD A v. INDRAPRASTHA GAS LIMITED & Ors.

High Court of Delhi in W. P. (C) No. 2034 of 2012 Arvind Datar, Suchindran B. N., Rakesh Dewan, Liz Mathew for the Appellant. c D Pinky Anand, ASG, Harish N. Salve, Parag Tripathi, Ashok Panda, K. K. Venugopal, V. Giri, B. A. Ranganathan, Ruby Singh Ahuja, Deepti Sarin, Neha Gupta, Manik Karanjawala, Anisha Mitra, Avinash Ganguli (For Karanjawala E & Co.), Sunita Rani Singh, B. K. Prasad, Debal Banerjee, Trinath Tadkamalla, Mrinal Ojha, Ridhi Sancpeti, for the Respondents and Caveator-in-person. The Judgment of the Court was delivered by F DIPAK MISRA, J. 1. The present appeal, by special leave, calls in question the legal defensibility and the tenability of the judgment and order dated 01.06.2012 passed by the High Court of Delhi in W.P.(C) No. 2034 of2012 whereby the G Division Bench has ruled that Petroleum and Natural Gas Regulatory Board (for short, "the Board") is not empowered to fix or regulate the maximum retail price at which gas is to be sold by entities such as lndraprastha Gas Ltd, to the consumers and further the Board is also not empowered to fix an'y H 222 SUPREME COURT REPORTS [2015] 7 S.C.R. A component of network tariff or compression charge for an entity having its own distribution network. On the aforesaid foundation, the High Court has opined that the provisions of Petroleum and Natural Gas Regulatory Board (Determination of Network Tariff for City or Luca! Natural Gas Distribution B Networks and Compression Charge for CNG) Regulations, 2008 (hereinafter referred to as "the Regulations") as far as it is construed to empower the Board to fix the tariff is unsustainable and accordingly as a sequitur the order dated 9.4.2012 to the extent of fixing the maximum retail price or C requiring the respondents to disclose the entire tariff and the compression charges to its consumers, is not in consonance with the Petroleum and Natural Gas Regulatory Board Act, 2008 (for brevity "the Act"), and accordingly quashed the same. D

#2. The facts which are essential to be adumbrated are that the respondent invoked the jurisdiction under Article 226 of the Constitution assailing the order dated 9.4.2012 issued by the Board under Section 22 of the Act determining the network tariff and compression charges for CNG in respect of E Delhi City Gas Distribution (CGD) network of the petitioner at Rs.38.58 per MMBtu and Rs.2.75 per kg. respectively w.e.f. 01.04.2008 and directing tlie petitioner therein to recover the said network tariff and compression charges for CNG F separatelythrough an invoice, without any premium or discount on a non-discriminatory basis and to appropriately reduce the selling price of CNG from the date of issuance of the order. Be it noted, the Board left the modalities and time frame for refund of differential network tariff and the compression G charges for CNG recovered by the petitioner therein w.e.f. 1.4.2008 in excess from its consumers to be decided subsequently. The said order was criticized on many a ground. The principal contention was that the Board does not have the power to direct the writ petitioner, the respondent no. 1 herein, H while charging its consumers, to disclose the network tariff and PETROLEUM & NATURAL GAS .REGULATORY BOARD v. 223 INDRAPRASTHA GAS LIMITED [DIPAK MISRA, J.] the compression charges and also to fix the said network tariff A and compression charges in any particular manner.

#3. The said stand was resisted by the learned counsel for the Board contending, inter alia, that Regulations 3 and 4 of the Regulations apply to the entities like the writ petitioner; B that the Board has the power to ask the writ petitioner, the respondent herein, to submit the network tariff and compression charges for CNG as per the Quality Regulations for approval of the Board; that the entity having accepted the said term as a condition for obtaining" exclusivity is bound by C the contractual obligation with the B~,ard and is now estopped from challenging the power of the Board; that the objects and reasons of the Act is to protect interests of the consumers and regard being had to the statutory context when an action is taken, no flaw could be found with the same; that Sections D 2(i), (m) and (w) of the Act are all intended to ensure that the consumer is not exploited; that Section 2(zn) of the Act defines the transportation rate and in the interpretative expanse, the order passed by the Board is absolutely defensible; that as per Section 11(e), the Hoard is empowered to regulate, inter E alia, the transportation rates; that Section 61 (2), especially, clauses (n), (t), (za) empower the Board to make regulations qua transportation tariff and any other matter which is required to be or may be specified by the Regulations or in respect of F which provision is to be made by the Regulations; that keeping in view the objective of the Act, the Regulations permit the Board to fix the network tariff and the compression charges and the action of the Board so fixing the network tariff and the compression charges cannot be interfered with; and that the G Regulations framed by the Board are consistent with the Act.

#4. The High Court observed that the question for adjudication was basically whether the Act authorises the Board to pass such an order and whether the intention of the H 224 SUPREMECOURT~EPORTS [2015] 7 S.C.R. A legislature is to confer the power of price fixation on the Board. The High Court referred to Section 11 of the Act and came to hold that:- B C "We thus conclude that PNGRBAct does not confer any power on the Board to fix/regulate price of gas as has been done vidP the impugned order dated gth April, 2012. Having held so, we do not deem it necessary to deal with the other Regulations impugned in the writ petition and suffice it is to state that any provision therein having the effect of empowering the Board to fix the price or the network tariff or compression charges for CNG, as long as not transportation rate, is beyond the competence of the Board and ultra vires the PNGRBAct and of no avail." D And again:- "We thus allow this writ petition to the extent of holding that the Petroleum and Natural Gas Regulatory Board is not empowered to fix or regulate the maximum retail price at which gas is to be sold by entities as the petitioner, to the consumers. We further hold that the Board is also not empowered to fix any component of network tariff or compression charge for an entity such as the petitioner having its own distribution network. The provisions of the Regulations (supra) in so far as construed by the Board to be so empowering it are held to be bad/illegal. Accordingly, the order dated 91 h April, 2012 to the extent so fixing the maximum retail price or requiring the petitioner to disclose the network tariff and compression charges to its consumers is struck down/quashed."

#5. Criticizing the judgment and order passed by the High Court, Mr. Arvind Datar, learned senior counsel for the appellant, has raised the following submissions:- E F G H PETROLEUM & NATURAL GAS REGULATORY BOARD v. 225 INDRAPRASTHA GAS LIMITED [DIPAK MISRA, J.] (a) There is a presumption of validity of subordinate legislation, and as long as the parent Act enables the framing of regulations they are valid. When section 2(zn), 22(1), 61 (2)(e), 61 (2)(t) of the Act empower the Board to frame regulations for all three categories, namely, common carrier, contract carrier and city or local natural gas distribution network, the Regulations are valid. The High Court has incorrectly held that these regulations are ultra vires the parent Act without referring to any specific section or provision. That apart, on a reading of the provisions of the Act it is also noticeable that there is no postulate that the power to frame ~tie transportation rate/ transportation tariff can only be exercised only when the city network becomes a common carrier or contract carrier. (b) While the city networks get market exclusivity for 3/5 years, they get infrastructure exclusivity for 25 years with further extension of 10 years at a time and the fixation of transportation rate/ transportation tariff has to be determined for the network of pipelines irrespective of whether they are common carriers, contract carriers or city networks. The Act and Regulations contemplate fixation of transportation rate/transportation tariff even at the stage of city network. It is quite clear that when the city network becomes a common carrier after the exdusivity period, the said transportation rate which is determined at the city network stage itself, would apply for carrying the gas of other suppliers under section 21 (2). (c)The High Court has erroneously opined that the transportation rate provided for is the rate to be charged by one entity under the Act from another for transporting/ carrying/moving gas of the other, for such a conclusion is completely contrary to the definition contained in A B c D E F G H 226 SUPREME COURT REPORTS [2015] 7 S.C.R. A B c D E F G H section 2 (zn). The transportation rate has to be determined even for city networks under sections 22( 1 ), 61 (2)(e) and 61 (2)(t) and that is the rate which can also be claimed from other gas suppliers but that does not mean that no transportation rate can be determined unless and until the pipeline becomes a comnion carrier. The High Court has flawed in holding that any provision therein having the effect of empowering the Board to fix the price or the Network Tariff or the Compression Charges for CNG, as long as not transportation rate, is beyond the competence of the Board and ultra vires the Act, and it is because though the Board cannot fix the selling price or monitor the selling price as natural gas has not been notified, yetthe Board has the power, and indeed the duty, to fix the network tariff and compression charges (which are nothing but the transportation rate/ transportation tariff) under the Act. (d) The High Court has committed gross illegality in its analysis while stating that the Board is not en:ipowered to fix any component of Network Tariff or Compression Charge for any entity such as the respondent herein having its own distribution network. It has also faulted in opining that the provisions of the Regulations insofar as construed by the Board fo be so empowering it are illegal. These findings recorded by the Division Bench are contrary to the provisions of the Act, for the Board can fix the transportation rate/transportation tariff and the fact that the rate will become applicable after expiry of the period of exclusivity does not make the Regulations themselves bad or illegal and it is absolutely clear that source of power comes from the provisions engrafted under Sections 2(zn), 22(1), 61 (2)(e) and 61 (2)(t) of the Act as they confer power on the Board to frame regulations for all three categories. PETROLEUM & NATURAL GAS REGULATORY BOARD v. 227 INDRAPRASTHAGAS LIMITED [DIPAK MISRA, J.] (e) The omission of 'city network' in Section 11 {e)(ii) is only accidental, and if the provisions of the Act are read as a whole, the power of the Board is clear as crystal for determining the transportation rate/transportation tariff for all categories. If the contention of the respondents is accepted, it will amount to rewriting.the provision as "transportation rates after city network becomes a common carrier or contract carrier" . . .. (f) The view expressed by the High Court to the extent that the Board is not empowered to fix any component of Network Tariff or Compression charge for an entity such as the respondent that has its bwn distribution network is fallacious, for the said findings are not in accord with to the provisions of the Act, and if the submissions are accepted, the Regulations will become applicable only after the period of exclusivity. The Central Government had supplied subsidized gas to the authorised entities to ensure that consumers do not have to pay a high cost for both piped natural gas (used for domestic purposes) and compressed natural gas (used for transportation) and has made it mandatory for the respondents to disclose the break up. Quite apart from that, Section 21 (1) that stipulates right of first use afterthe exclusivity period and Section 21 (2) which provides that other entities are liable to pay minimum transportation rate for using the common carrier, do not indicate that the Board has no power to fix the transportation rate/ tariff during the exclusivity period or that it would apply to only the gas transported for other entities. The respondent company is obliged to indicate the transportation rate/ tariff as soon as it is determined. Even if the respondent's contention is accepted, the rate/tariff has to be indicated after the exclusivity period not only for the gas of other entities but also for the gas_ that is supplied by the A B c D E F G H 228 SUPREME COURT REPORTS [2015] 7 S.C.R. A B authorised entity itself. Section 20(4) mandates the Board to fully protect consumer interest while granting exclusivity to the city network and the consumer interest is protected by the Board determining the transportation tariff being applicable to and being indicated for all the gas transported in the city network, whether it belongs to other entities or to the entity owning and operating the city network.

#6. Mr. Harish Salve and Mr. Parag S. Tripathi, learned C senior counsels, resisting the submissions raised by Mr. Datar, learned senior counsel for the appellant-Board, have raised the following contentions. (A) As per the schematic intendment of the Act, after the expiry of period of exclusivity under Section 20(4), the Board, if decides, in exercise of the statutory powers under Section 20-22, can declare the network as a common/contract carrier, and then alone, in respect of third party suppliers of gas, who seek to use the excess capacity i11 the pipeline of the network, the Board may fix the transportation rate, which the 1s1 respondent may charge from such a third party supplier. The consumers of natural gas, whether of the first respondent, or of the third party supplier of gas, does not enter into the scene at all and has no role to play whatsoever. The transportation in question whether by the network while supplying to its consumers or by a common/contract carrier in respect of the third party suppliers are the rates and costs of transportation relevant only to the owner/ supplier of the gas and the said rate has no meaning or relevance as far as the consumer, who is the purchaser of such gas, is concerned, other than the fact that the transportation expenses would also form a part of the consolidated final price which would be raised and D E F G H PETROLEUM & NATURAL GAS REGULATORY BOARD v. 229 INDRAPRASTHA GAS LIMITED [DIPAK MISRA, J.] recovered by respondent as also third party supplier from the respective consumers. (B). The definition of Common Carrier in Section 20) and Contract Carrier in Section 2(m) postulate certain conditions and the definition of city or local natural gas distribution network in Section 2(i) does not contain the said crucial twin conditions. That apart, Section11(a) and Section 11(e) permit the issuance of regulations which determine access and the transportation rate for Common Carrier or Contract Carrier, and the said provision limits the power of the Board to issue regulations only in respect of access to the network and not for the transportation rate for the network and, therefore, the stand of the appellant that there is an accidental omission is unacceptable because the intention of the legislature is absolutely clear and unambiguous. (C). The power·can only be exercised in respect of common carrier/contract carrier if it is a network in respect of which the power is sought to be exercised and then also as a first step the network must be declared or authorised as a common carrier or a contract carrier · withinthe meaning of Sections 20-22; and, therefore, as far as a network is concerned, there is no right to determine transportation rate. Such power is specifically limited in respect of common/contract carrier under Section 11 (e)(ii). The very concept of transportation rate which is defined in Section 2(zn) makes it clear that it is the rate for moving each unit of petroleum, petroleum products or natural gas as may be fixed by the Regulations and Section 21 (2) which uses the expression 'transportation rate', has three elements, which makes it clear that the transportation rate has relevance only in A B c D E F G H 230 SUPREME COURT REPORTS [2015] 7 S.C.R. A B c D E F G H respect of the rates payable by a third party entity, which is utilizing the excess capacity in the existing pipeline of a common/contract carrier.and the Board does not have the power to determine the transport rate. (0). The Board has been empowered by Regulations to determine t~e exclusivity period under Section 20(4) of any pipeline. The effect of this declaration of exclusivity ' is that under Sections 20 - 22, during the period of exclusivity, the Boar.d is disabled from declaring such pipeline, whether existing or a new one, as a common/ contract carrier; and once a pipeline is declared to be a common carrier/contract carrier, it is required to make available its excess capacity as a part of the open access regime, to any third party supplier of gas. Such a third party may either be an importer or purchaser or a producer of gas seeking to transport its gas using the pipeline of any other entity. Therefore, critical scanning of Section 20 to 22 do not confer any power on the Board to fix the transportation tariff. Section 22( 1) makes it clear that the right to fix transportation tariff is subject to other conditions of the Act and when the provisions contained in Sections 20), 2(m), 2(i), 2(zn), 11 (e), 11 (f)(iii), 11 (f)(vi) and 22(2) are read in a conjoint manner, it is graphically clear that the Board has not been conferred the power to fix the transport tariff by the legislature and, therefore, it cannotdo so by a regulation. The reliance by the Board on Section 61 (2) (q) & (t) is misplaced, for Section 61 (1) of the 'Act permits the Board to make regulations consistent with the Act and the Act which confers power on the Board to frame the Regulations does not empower it to do so. That apart, Section 61 deals with the general regulation making power of the Board in terms of the Sections specified in the Act; and Section 61 (2)( q) and (t) relate back to Section 22(1) which itself is "subject to" PETROLEUM & NATURAL GAS. REGULATORY BOARD v. 231 INDRAPRASTHAGAS LIMITED [DIPAK MISRA, J.] the other provisions of the Act and, hence, even if Section 61(t) is read with Section 22(1), it would not override Section 11(e) read with Section 2(zn) and 21(2) of the Act. ' A

#7. In reply to the aforesaid submissions, Mr. Datar, B learned senior counsel has canvassed the following propositions:- (I) The contentions urged by the respondent are untenable, for the transportation rate has to be determined on the basis of voluminous data, which has to be collected, collated and analyzed and unless the rate is , fixed even during the five year period, there will be no ; rate available for the common carrier at the eQ_d of the exclusivity period and it will be absurd to suggest that the entire exercise has to begin only after the ci!Y}].~twork becomes a common carrier. The transportation rate has to be determined for a network of pipelines under ~ection 2(zn) and is not a separate determination Jor city networks, common carrier or contact carrier as t~e, object of determining the rate is also to determine the rate at which the cost of transportation is permitted to be recovered and it has to be done in a reasonable manner as mandated under Section 22(2)(b). The omission of "city or local gas distribution network" in Section 11 (e)(ii) is clearly accidental because in the Act as. well as Regulations, three categories viz. common carrier, contract carrier and city or local gas distribution network have been used together, and the purpose becomes manifest on a perusal of Section 61 (2)(e) which specifically refers to Section 11 (e). (II) The Board as a regulator has the obligation to ensure that the consumers are not exploited and under Section 20(4) the Board grants monopoly for 25 years with further c D E F G H 232 SUPREME COURT REPORTS [2015] 7 S.C.R. A B c D E F G H extension of 1 O years at a time and barring unforeseen circumstances, such a network will have exclusive infrastructure monopoly for several decades. Therefore, in the factual matrix, the Board has a duty to ensure that consumer interest is protected during the monopoly period, as mandated under Section 20(4) and that can be done by ensuring the investment by the gas company in the transportation infrastructure of the city network is recovered in a reasonable manner for all the gas transported in the city network.over the economic life of the network. It is not the stand of the Board that it · does not have the power to monitor the Maximum Retail Price (MRP) however, the transportation rates/tariff would indicate it is the price charged to the consumer so that it does not result in excessive profiteering and under these circumstances, it is the duty of the respondent to reveal the transportation prices to the Board as well as to the consumers. (Ill) Section 20(4) gives the right to the Board to grant exclusivity to the city or local natural gas distribution network for such period as the Board may decide and once it has the power to give exclusivity to a city or local natural gas distribution network owning entity so that only it can lay, build and operate such network in a geographical area and under these circumstances it becomes the duty of the Board and as per the stipulations under Section 20(4) it has to be done in a transparent manner protecting the consumer interest. In addition to it, the duty is cast on the Board under Section 20(5) to be guided by the objectives of promoting competition among the entities, avoiding infructuous investment, maintaining or increasing supplies or for securing equitable distribution or ensuring adequate availability of natural gas throughout the country and, therefore, the PETROLEUM & NATURAL GAS REGULATORY BOARD v. 233 INDRAPRASTHA GAS LIMITED [DIPAK MISRA, J.] Board can determine the transportation rate/tariff. If the stand of the respondent is accepted, the consumers would never know the transportation rate, since it is possible that in many cases there may not be any other gas supplier who is using the network of pipelines after the exclusivity period.

#8. Having enumerated the submissions in reply by the first respondent, we must record the submissions of the second respondent, that is, Union of India. The following proponements have been urged by Ms. Pinky Anand, learnedASG. (i) There is no legislative intent for allowing the Board to determine the pricing of gas, i.e. the price which the entity charges from the ultimate customers. The Act, while protecting the interests of the consumers, has not empowered the Board to fix the price at which the entities will sell the petroleum products or natural gas to the consumers, for the MRP is to be fixed by the entity. (ii)As regards the applicability of transportation tariff determined through the Regulations, it is clear from the provisions of the Act that such transportation tariff is applicable only in respect of an outside entity that is willing to use the CGD network and that such tariff is payable by that entity to CGD network operator. The transportation tariff notified through the BoC1rd Regulations is not applicable for CGD entity when it transports its own gas for supply to' individual customers. (iii) The Board is merely authorised to monitor prices and is required to ensure fair competition amongst entities that are supplying CNG or PNG to the end consumers. The Act provides for fair competition by allowing entry to a third party for supplying gas to the end consumers on a non-discriminatory open access basis A B C o E F G H 234 SUPREME COURT REPORTS [2015] 7 S.C.R. A B c D E F G H and in the said process the third party is required to pay transportation tariff to the CGD operator at the rates notified by the Board. The purpose of notification of the said rate is to prevent the CGD operator from putting up any kind of entry barrier in the form of a higher transportation tariff for the third party. (iv) Section 22 of the Act read with Section 20, 21 and 2(i:n) of the Act, the Board is empowered to regulate the transportation rate or transportation tariff only for a city or local natural distribution network subject to the provisions as provided in the Act. When such city or local natural gas distribution network is declared as a common carrier or a contract carrier by the Board and it is used by any other entity on common carrier or contract carrier basis, then only as per the provisions of the Act, the Board is only. entitled to fix, by regulations, the transportation rate or the transportation tariff which the entity owning and operating as a city or local natural gas distribution network would charge from other entities which use its network on common carrier or contract carrier basis for transporting their gas. (v) The Board is not empowered to fix the price at which entities will market or sell the notified petroleum products or natural gas. The MRP il? to be fixed by the entity. The Board shall only monitor the prices and take corrective measures to prevent restrictive trade practices by the entities. As regards regulation of the activities of transmission and distribution of petroleum products and natural gas, the Board will oversee access to pipelines and city or local natural gas distribution networks on non discriminatory, common carrier/contract carrier principle for ensuring a level playing field for all entities. That apart, the concept of allowing capacity in a city or local natural PETROLEUM & NATURAL GAS REGULATORY BOARD v. 235 INDRAPRASTHAGAS LIMITED [DIPAK MISRA, J.] gas distribution network to be used by any third party entity on non-discriminatory common carrier/contract carrier principle shall incetivize emergence of independent marketers of natural gas. Such independent marketers shall enter into transportation contracts with the entity, owning and operating the city or local natural gas distribution network for transportation of their gas. This, in turn, will foster fair trade and competition in marketing amongst entities (vi) The Board is.entitled to fix the transportation rate for gas transmission and distribution in all cases where gas is transported on common carrier or contract carrier principle. The transportation rate so fixed by regulator shall be paid by the third party entities to the entity,-0wning and operating the city or local natural gas distribution network for transporting their gas on common.carri~r/ contract carrier principle. Thus, by observing non discriminatory open access to pipelines and city or local natural gas distribution networks on common carrier/ contract carrier principle at the transportation rates fixed by regulations, a level playing field shall be ensured for all the entities engaged in marketing and sale of natural gas. In such a market condition, gas-on-gas competition . ' and the inter-fuel competition will lead to emergence of fair trade and competition amongst entities, which in turn, will protect the interest of consumers. ' 1 • A B c D E F

#9. Mr. K.K. Venugopal, learned senior counsel appearing for the intervenor, Central U.P. Gas Ltd., has contended that the Board does not have the power to fix MRP and the G distribution entity has a fundamental right to carry on the trade, subject to restriction under Article 19( 1 )(g) of the Constitution and in the case at hand, the Act, does not confer any power on the Board to fix the MRP, but on the other hand, it expressly H 236 SUPREME COURT REPORTS [2015) 7 S.C.R. 0 A provides for the MRP to be fixed by the entity themselves as per Section 2(x) of the Ad. Learned senior counsel would contend that once the Board has no jurisdiction/ authority to fix the MRP, it is not entitled to fix any element/ component of the MRP as it would bring an anomalous situation. The submission B of the Board that the distribution entity qan charge the MRP, but it has the power to regulate the component, that is, the transportation charges is a futile exercise, a brutum fulmen, for the simple reason that however low may be the component of MRP determined by the Board, the authorised entity can C virtually ignore the same. It is argued by him that the Board is a creature of the Act and it can only exercise its functions in accordance with and within the four corners of the said Act and it cannot prescribe what it calls network tariff and compression charge under the Regulations, because the statute refers to fixation of "transportation tariff/ transportation rate" but does not mention of 'network tariff or 'compression charges'. In the absence of any power conferred under the Act to frame regulations in thatregard, the Regulations clearly transgress the enactment and hence, the Regulations to that extent are ultra vi res. It is urged by him that 'network tariff' is not the same as 'transportation rate' and the Board cannot assume such an authority by employing a different analogy. Placing reliance on Section 11(e)(ii), it is argued by the learned F senior counsel that the said provision which provides for Board's function and empowers the Bo'ard to frame regulations, employs the words 'transportation rates for common carrier or contract carrier' and they remotely do not purport to fix rates for 'network tariff' or 'compression charges' G for city gas distribution network. In addition, it is propounded by him that reliance on Sections 21 (2) and 22(1) and all other provisions are absolutely misconceived and the assumption that the Board as a regulator to look after consumer interests, cannot travel beyond the statutory limit. E H PETROLEUM & NATURAL G.A.S REGULATORY BOARD v. 237 INDRAPRASTHAGAS LIMITED [DIPAK MISRA, J.]

#10. Dr. Jatin Thukral, who has been allowed to intervene, A has referred to the background of the Act and on that foundation has canvassed that "transportation rate" is inseparably related to open access for every commercial gas distribution entities to either common carrier or contract carrier or city or local natural gas distribution regard being had to the manner in which B the said words hav~ been employed by the legislature in various provisions of the Act. It is his further submission that Section 61(2)(t) is controlled by sub-section 22(1) which in turn is guided by Section 22(2) and all the provisions are associated with common or contract carriers only and by no stretch of C imagination, it confers any power on the Board to fix transportation rate, as it is only referable to the rate charged by one commercial entity from any commercial entity for using its gas transportation networks. In essence, his submission is D that the appeal is devoid of merit and deserves to be dismissed.

#11. Before we proceed to appreciate the rivalised contentions raised at the Bar, it is seemly to state that in terms of Section 22 of the Act, the Board has framed the Regulations. Placing reliance on the Regulations, the Board has issued the E order dated 9.4.2012, which deals with the Network Tariff for City or Local Natural Gas Distribution Network and Compression Charge for CNG in respect of the Delhi CGD Network of lndraprastha Gas Limited (IGL). Clause 1 deals F with the Regulatory Framework. Clause 1.1 reads as follows:- "1.1 In terms of Sections 22 of the PNGRB Act, 2006, the Board is entrusted with the responsibility to lay down the transportation tariff for city or local natural gas distribution network. As per the relevant provisions of the PNGRB (Authorizing Entities to Lay, Build, Operate or Expand City or Local Natural Gas Distribution Networks) Regulations, 2008 read with the said statutory provisions, the Board is empowered to determine the G H 238 SUPREME COURT REPORTS (2015] 7 S.C.R. Network Tariff and Compression Charge for CNG to be charged by the entity laying, building, operating or expanding City or Local Natural Gas Distribution Network either before the appointed day or on a day subsequent thereto." A B After so stating, the Board has proceeded to provide the methodology for determination of the· network tariff and compression charge for the CGD network which has been stipulated in the Regulation dated 19.3.2008. The relevant C part of the order, we may profitably reproduce:- "3.19 As per the provisions of the PNGRB (Determination of Network Tariff for City or Local Natural Gas Distribution Networks and Compression Charge for CNG) Regulations, 2008 the actual performance with respect to the capital and operating costs during the previous review period against the identified parameters shall be monitored and the variations shall be adjusted in the calculations on a prospective basis considering the remaining period of economic life of the CGD project.

#4. Decision

4.1 While the PNGRB (Determination of Network Tariff for City or Local Natural Gas Distribution Networks and Compression Charge for CNG) Regulations, 2008 were notified on 19th March 2008, for the purpose of ease in calculations, the applicable network tariff and compression charge for CNG determined by the Board shall be applicable from 1st April, 2008. Accordingly, the Network Tariff and the Compression Charge for CNG in respect of the Delhi CGD Network of IGL shall be Rs.38.58 per MMBTU and Rs.2.75 per KG respectively with effect from 1st April, 2008.

4.2 As per the provisions of the PNGRB (Authorizing Entities to Lay, Build Operate or Expand City or Local Natural Gas Distribution Networks) Regulations, 200&, IGL shall recover the Network Tariff and Compression Charge for CNG separately through an invoice without any premium of discount on a non-discriminatory basis. Further, in conformity with the decision conveyed vide letter dated 23.5.2011 mentioned in para 2.3 above, the difference between the Network Tariff and Compression Charge for CNG submitted by IGL and that determined by the Board as given in the table above would be ' reflected through appropriate reduction in selling prices from the date of issuance of this Order. The modalities and time frame for refund of differential Network Tariff and the Compression Charge for CNG for the period from 01.4.2008 till the date of issuance of this Order shall be decided and advised by the Board subsequently." A B c D E F G

#12. As the factual matrix uncurtains, the issuance of the said order compelled the 1st respondent to approach the High Court seeking its quashment principally on the ground that such a power has not been conferred by the Act and the Board, by H 240 SUPREME COURT REPORTS [2015) 7 S.C.R. A B framing the resolutions cannot arrogate such power to itself in the absence of the source of power. That was the substratum of challenge before the High Court where the Board failed to support and sustain its order and the 1st respondent succeeded in its assail and the contentions raised before this Court are fundamentally embedded on the said fulcrum. Mr. Datar, learned senior counsel, apart from many a provision, has also . commended us to the objects and reasons of the Act to highlight the role of the Board as a regulator. In view of the said submission, we think it apt to refer to the objects and C reasons of the Act. It reads as follows:- D E "An Act to provide for the establishment of Petroleum and Natural Gas Regulatory Board to regulate the refining, processing, storage, transportation, distribution, marketing and sale of petroleum, petroleum products and natural gas excluding production of crude oil and natural gas so as to protect the interests of consumers and entities engaged in specified activities relating to petroleum, petroleum products and natural gas and to ensure uninterrupted and adequate supply of petroleum, petroleum products and natural gas in all parts of the country and to promote competitive markets and for matters connected therewith or incidental thereto." F

#13. Bearing the purpose of the Act in mind, we shall refer to the relevant provisions of the Act. Section 1 (4) provides that the Act applies to refining, processing, storage, transportation, distribution, marketing and sale of petroleum, petroleum products and natural gas excluding production of G crude oil and natural gas. Section 2(d) of the Act defines authorised entity to mean that any entity registered by the Board under Section 15 to market any notified petroleum, petroleum products or natural gas, or to establish and operate H liquefied natural gas terminals. PETROLEUM & NATURAL GAS REGULATORY BOARD v. 241 INDRAPRASTHA GAS LIMITED [DIPAK MISRA, J.]

#14. Section 2(i) of the Act on which emphasis has been A laid defines "city or local natural gas distribution network", relevant part of it reads as 1Jnd, er:- "2(i) "city or local natural gas distribution network" means an interconnected network of gas pipelines and the associated equipment used for transporting natural gas from a bulk supply high pressure transmission main to the medium pressure distribution gri~ and subsequently to the service pipes supplying natural gas to domestic, industrial or commercial premises and CNG stations situated in a specified geographical area."

#15. Section 2(j) and 2(m) define 'common carrier' and 'contract carrier' respectively. They read as follows:- "2(j) "common carrier" means such pipelines for transportation of petroleum, petroleum products and natural gas by more than one entity as the Board may declare or authorise from time to time on a nondiscriminatory open access basis under sub-section (3) of section 20, but does not include pipelines laid to supply- (i) petroleum products or natural gas to a specific consumer; or (ii)crude oil; Explanation~ For the purposes of this clause, a contract carrier shall be treated as a common carrier, if - {a) such contract carrier has surplus capacity over and above the firm contracts entered into; or {b) the firm contract period has expired. s C D E F G 2(m) "contract carrier" means such pipelines for H 242 SUPREME COURT REPORTS [2015] 7 S.C.R. transportation of petroleum, petroleum products and natural gas by more than one entity pursuant to firm contracts for at least one year as may be declared or authorised by the Board from time to time under sub- section (3) of section 20." A B

#16. The aforesaid definitions basically deal with pipelines and they are regulated under the Act. The dictionary clause speaks of the nature of activity. There is a noticeable difference between common carrier pipeline and contract carrier pipeline C on one hand and "a city of local natural gas distribution network" on the other. On a perusal of the definitions of the common carrier and contract carrier, it is demonstrable that they refer to pipelines for transportation of petroleum or petroleum products and natural gas by more than one entity. The D definition "city or local gas distribution network" means an. interconnected network of gas pipelines and the associated equipment used for transporting natural gas from a bulk supply high pressure transmission main to the medium pressure distribution grid and subsequently to the service pipes E supplying natural gas to domestic, industrial or commercial premises and CNG stations situated in a specified geographical area. It deals with specified geographical area. It does not refer to a pipeline or transport of natural gas. It is F specifically a pipeline network for transport of natural gas to its own consumers. This being the position, as per the dictionary clause, it is pertinent to refer to Section 20 that provides for decfaring, laying, building, etc. of common carrier or contract carrier and city or local natural gas distribution I G network. The said provision is as follows:- "20 Declaring, laying, building, etc., of common carrier or contract carrier and city or local natural gas distribution network:- H ( 1) If the Board is of the opinion that it is necessary or PETROLEUM & NATURAL GAS REGULATORY BOARD v. 243 INDRAPRASTHAGAS LIMITED [DIPAK MISRA, J.] expedient, to declare an existing pipeline for transportation of petroleum, petroleum products and natural gas or an existing city or local natural gas distribution network, as a common carrier or contract carrier or to regulate or allow access to such pipeline or network, it may give wide publicity of its intention to do so and invite objections and suggestions within a specified time from all persons and entitles likely to be affected by such decision. (2) For the purposes of sub-section (1), the Board shall provide the entity owning, the pipeline or network an opportunity of being heard and fix the terms and conditions subject to which the pipeline or network may be declared as a common carrier or contract carrier and pass such orders as it deems fit having regard to the public interest, competitive transportation rates and right of first use. (3) The Board may, after following the procedure as specified by regulations under section 19 and sub- sections (1) and (2), by notification,- (a) declare a pipeline or city or local natural gas distribution network as a common carrier or contract carrier; or (b) authorise an entity to lay, build, operate or expand a pipeline as a common carrier or contract carrier; or A B C D E F (c)allow access to common carrier or contract carrier or city or local natural gas distribution network; or G (d) authorise an entity to lay, build, operate or expand a city or local natural gas distribution network. (4) The Board may decide on the period of exclusivity H 244 SUPREME COURT REPORTS [2015] 7 S.C.R. to lay, build, operate or expand a city or local natural gas distribution network for such number of years as it may by order, determine in accordance with the principles laid down by the regulations made by it, in a transparent manner while fully protecting the consumer interests. (5) For the purposes of this section, the Board shall be guided by the objectives of promoting competition among entities, avoiding in fructuous investment, maintaining or increasing supplies or for securing equitable distribution or ensuring adequate availability of petroleum, petroleum products and natural gas throughoutthe country and follow such principles as the Board may, by regulations, determine in carrying out its functions under this section." A B c D On a reading of the aforesaid provision, it is clear as day that the Board has been conferred with the power to declare an existing pipeline for transportation of petroleum, petroleum products and natural gas or an existing city or local E natural gas distribution network as a common carrier or contract carrier and regulate or allow access to such pipeline or network. Sub-Section (1) prescribes for giving wide publicity of the Bo;:ird's intention. Sub-Section (2) stipulates affording of opportunity of hearing to the pipeline or network for fixing terms and conditions subject to which pipeline or network be declared as common carrier or contract carrier. The Board has been authorised, after following due procedure as specified by Regulations under Section 19 and under sub-Sections (1) and (2) by notification to declare a pipeline or city or local natural G gas distribution network as a common carrier or contract carrier and do certain acts. Sub-Section (4) enables the Board to decide on the period of exclusivity to lay, build, operate or expand a city or local natural gas distribution network for such H number of years. The objectives by which the Board is to be F PETROLEUM & NATURAL GAS REGULATORY BOARD v. 245 INDRAPRASTHA GAS LIMITED [DIPAK MISRA, J.] guided are promoting competition among entities, avoiding A infructuous investment, maintaining or increasing supplies or securing equitable distribution or ensuring adequate availability of petroleum, etc.

#17. Section 21 deals with right of first use, etc. The said B provision reads as follows:- "21. Right of first use, etc.:- (1) The entity laying, building, operating or expanding a pipeline for transportation of petroleum and petroleum products or laying, building, operating or expanding a city or local natural gas distribution network shall have right of first use for its own requirement and the remaining capacity shall be used amongst entities as the Board may, after issuing a declaration under section 20, determine having regard to the needs of fair competition in marketing and availability of petroleum and petroleum products throughout the country: Provided that in case of an entity engaged in both marketing of natural gas and laying, building, operating or expanding a pipeline for transportation of natural gas on common carrier or contract carrier basis, the Board shall require such entities to comply with the affiliate code of conduct as may be specified by regulations and may require such entity to separate the activities of marketing of natural gas and the transportation including ownership of the pipeline within such period as may be allowed by the Board and only within the said period, such entity shall have right of first use. (2) An entity other than an entity authorised to operate shall pay transportation rate for use of common carrier . ,or contract to the entity operating it as an authorised entity, c D E F G H 246 SUPREME COURT REPORTS [2015) 7 S.C.R. A B C (3) An entity authorised to lay, build, operate or expand a pipeline as contract carrier or to lay, build, operate or expand a city or local natural gas distribution network shall be entitled to institute proceedings before the Board to prevent, or to recover damages for, the infringement of any right relating to authorization. Explanation:- For the purposes of this sub-section, "infringement of any right" means doing of any act by any person which interferes with common carrier or contract carrier or causes prejudice to the authorised entity." The aforesaid provision stipulates the right of first use and also prescribes certain conditions. 0

#18. Section 22 on which reliance has been placed deals with transportation tariff. The said provision is reproduced below:- , "22. Transportation tariff:- (1) Subject to the provisions of this Act, the Board shall lay down, by regulations, the transportation tariffs for common carriers or contract carriers or city or local natural gas distribution network and the manner of determining such tariffs. (2) For the purposes of sub-section (1 ), the Board shall be guided by the following, namely:- (a) the factors which may encourage competition, efficiency, economic use of the resources, good performance and optimum investments; (b} safeguard the consumer interest and at the same time recovery of cost of transportation in a reasonable manner; E F G H PETROLEUM & NATURAL GAS REGULATORY BOARD v. 247 INDRAPRASTHA GAS LIMITED [DIPAK MISRA, J.] (c) the principles rewarding efficiency in performance; A (d) the connected infrastructure such as compressors, pumps, metering units, storage and the like connected to the common carriers or contract carriers; (e) benchmarking against a reference tariff calculated based on cost of service, internal rate of return, net present value or alternate mode of transport; (f) policy of the Central Government applicable to common carrier, contract carrier and city or local distribution natural gas network." B c On a plain reading of the aforesaid, it is manifest that the Board has the power to provide by Regulations the D transportation tariff for common carrier or contract carrier or city or local natural gas distribution network and the manner of distribution of such tariffs.

#19. The question that arises for consideration is whether E reading of the aforesaid provisions namely, Sections 20 to 22 of the Act, it can be construed that they confer any power on the Board to fix the transportation tariff of a consumer of natural gas. We have also referred to sub-Section (4) ofSection20 which confers the power on the Board to c:lecide the period of F exclusivity and the network of a common/contract carrier. Section 21, as indicated earlier, deals with the right of first use. The transportation tariff, which finds place in Section 22( 1 ), commences with the words "subject to the provisions of this Act". The said provision confers power on the Board to lay G down, by regulation, the transportation tariff for common carriers or contract carriers or city or local natural gas distribution network and the manner of determination of such tariffs.

#20. At this stage, it is necessary to appositely understand the said expression. In The Commissioner of Wealth Tax, Andhra Pradesh, Hyderabad v. Trustees of H.E.H. Nizam's Family (Remainder Wealth Trust), Hyderabacf this Court was dealing with the expression "subject to" in the B context of the Wealth Tax Act, 1957. Section 3ofthe said Act imposed the charge of wealth tax subject to other provisions of the Act. In that context, the Court opined that Section 3 has to be made expressly subject to Section 21 and it must yield to that Section insofar as the latter makes a special provision C for assessment of a trustee of a trust. In Ashok Leyland Ltd. v. State of T.N. and Another, it has been held that "subject to" is an expression whereby limitation is expressed. In K.R.C.S. Balakrishna Chetty and Sons & Co. v. The State , this Court was interpreting Section 5 of Hle Madras General Sales Tax Act, 1939 wherein the Legislature had appended the expression "subject to" and while interpreting the said words, the Court ruled that they are meant to effectuate the intention of law and the correct meaning of the expression is "conditional one".

#21. In South India Corporation (P) Ltd. v. Secretary, Board of Revenue, Trivandrum and another', the Constitution Bench has ruled that the expression "subject to" in the context convey the idea of a provision yielding place to another provision or other provision to which it was made subject to. In B.S. Vadera and another v. Union of India and others5, this Court while dealing with the expression "any rule so made shall have effect, subject to provisions of any Act G occurring in the proviso to Article 309" ruled that:-
