“All contracts made in the exercise of the executive power of the Union or of a State shall be expressed to be made by the President, or by the Governor of the State, as the case may be, and all such contracts and all assurances of property made in the exercise of that power shall be executed on behalf of the President or the Governor by such persons and in such manner as he may direct or authorise.”
“The PSC terms in outline 3. Article 7.3 of the PSCs obliges the Contractor to carry out the exploitation of the fields at its sole risk, cost and expense, expeditiously and in accordance with good international petroleum industry practice. The work programmes to be carried out under the PSCs are to be approved by the Management Committee (Article 5.6(a)), a body consisting of representatives of each of the four parties (Article 5.2) with the Government representative having an effective power of veto (Articles 5.7 and 5.13). The initial programme for development (as opposed to exploration or production) was to follow the indicative plan annexed as Appendix G. Appendix G sets out a non-exclusive list of matters which were to be included in the development plan. Article 13.1.2 provides that those plans for development would be revised, subject to Management Committee approval, by the Contractor in a 'Development Plan first submitted pursuant to this Contract'. That initial development plan is also referred to as the 'Initial Plan of Development', or 'IPOD'. Subsequent plans, including variations to previous plans, might then be approved by the Management Committee. 4. Article 13 of the PSCs entitles the Contractor to recover its costs from the total volume of petroleum produced and saved from the fields in each financial year. Article 13.1.2 limits the extent to which Development Costs may be recovered in this way. It provides that the recovery of 'Development Costs' is to be capped by the Cost Recovery Limit or 'CRL'. The CRL is US$545 million for Tapti and US$577.5 million for Panna Mukta. Development Costs incurred by the Contractor in excess of these limits fall to be borne by the Contractor. If, in certain specified circumstances, the CRL is exceeded, it can be increased to reflect those circumstances, either by the Management Committee or, in default of agreement by the Management Committee, by an arbitral tribunal (Articles 13.1.4(c) and 13.1.5)… 6. The PSCs are governed by Indian law (Article 32.1), save that the arbitration agreement in each of them, found in Article 33, is governed by English law (Article 33.12). The PSCs also state at Article 33.9 that arbitration proceedings are to be conducted in accordance with 'the arbitration rules of the United Nations Commission on International Trade Law (UNCITRAL) of 1985’; it is common ground that the date was a mistake, and the reference was intended to be to the 1976 UNCITRAL Arbitration Rules. In the event of any conflict between the UNCITRAL Rules and the provisions of Article 33, the provisions of Article 33 are to prevail (Article 33.9). The seat of arbitration was agreed to be London: Article 33.12 originally provided as much, and although the seat was changed to Paris when the Second Claimant became part of the BG Group, it was then changed back to London on an ad hoc basis for the purposes of the present arbitral proceedings.”
“This Contract shall not be amended, modified, varied or supplemented in any respect except by an instrument in writing signed by all the Parties, which shall state the date upon which the amendment or modification shall become effective.”
“(a) A "Final Partial Consent Award" dated29 July 2011 (the "Consent Award"). This recorded in particular the ad hoc agreement of the parties that London was to be the seat of the arbitration. (b) A "Final Partial Award on Arbitrability" dated12 September 2012 (the "Arbitrability Award"). In this award the Tribunal determined that certain specific matters whose arbitrability had been challenged were arbitrable… (c) A "Final Partial Award on Issues B, C and D of the May 2012 Issues" dated10 December 2012 (the "CRL Award"). The CRL Award concerned, among other things, how the CRL cap was to operate on recovery of Development Costs by [Reliance/BG] as a matter of the true construction of Article 13.1 of the PSCs… (d) A "Final Partial Award" dated12 October 2016 …The Award was issued after four hearings, in November 2013, September 2014, November 2014 and October 2015. (e) A "Final Partial Award" dated11 January 2018 , disposing of disputes relating to certain audit exceptions.”
“5. Res judicata is, thus, a doctrine of fundamental importance in our legal system, though it is stated to belong to the realm of procedural law, being statutorily embodied in section 11 of the Code of Civil Procedure, 1908. However, it is not a mere technical doctrine, but it is fundamental in our legal system that there be an end to all litigation, this being the public policy of Indian law. The obverse side of this doctrine is that, when applicable, if it is not given full effect to, an abuse of process of the Court takes place. However, there are certain notable exceptions to the application of the doctrine. One well known exception is that the doctrine cannot impart finality to an erroneous decision on the jurisdiction of a Court. Likewise, an erroneous judgment on a question of law, which sanctions something that is illegal, also cannot be allowed to operate as res judicata. This case is concerned with the application of the last mentioned exception to the rule of res judicata.”
“34.1 The general rule is that all issues that arise directly and substantially in a former suit or proceeding between the same parties are res judicata in a subsequent suit or proceeding between the same parties. These would include issues of fact, mixed questions of fact and law, and issues of law. 34.2 To this general proposition of law, there are certain exceptions when it comes to issues of law… 34.2.2 An issue of law which arises between the same parties in a subsequent suit or proceeding is not res judicata if, by an erroneous decision given on a statutory prohibition in the former suit or proceeding, the statutory prohibition is not given effect to. This is despite the fact that the matter in issue between the parties may be the same as that directly and substantially in issue in the previous suit or proceeding. This is for the reason that in such cases, the rights of the parties are not the only matter for consideration (as is the case of an erroneous interpretation of a statute inter parties), as the public policy contained in the statutory prohibition cannot be set at naught…”
“4.9…And whilst it could be said that the threshold matters/objections [the Government] now seeks to raise apply to ‘such evidence’, they apply equally to the entire Agreements Case [Reliance/BG] had raised prior to the release of the [2016 Award] and which the Tribunal has already determined in the Agreements Case Award. Whilst [the Government] had referred to Articles 297 and 299 of the Constitution of India, Article 34.2 of the PSC and limitation in the course of these arbitral proceedings, it is clear that it did not do so in respect of or in response to the Agreements Case. No good explanation has been provided – and there cannot be any justification – for [its] failure (see also paragraph 4.11 below): the same threshold matters/objections [it] now seeks to rely on, at the stage of remission, solely in respect of the Balance EPOD Agreements Case could have been raised prior to the release of the [2016 Award] and the Agreements Case Award. And they should have been raised prior to the release of the [2016 Award] and the Agreements Case Award. This much is clear from the Henderson v Henderson rule which has been cited, with approval, by the UK Supreme Court in Virgin Atlantic…”
“17. Res judicata is a portmanteau term which is used to describe a number of different legal principles with different juridical origins. As with other such expressions, the label tends to distract attention from the contents of the bottle. The first principle is that once a cause of action has been held to exist or not to exist, that outcome may not be challenged by either party in subsequent proceedings. This is “cause of action estoppel”
“4.15 It is thus clear that the Henderson v Henderson rule…provides a complete answer to [the Government’s] threshold matters/objections it now seeks to raise at the stage of remission in response to [Reliance/BG’s] Balance EPOD Agreements Case. It is hence not open to the Tribunal to consider [the Government’s] threshold matters/objections.”
“6.4 [The Government’s] argument taken to its ultimate conclusion would mean that any application by the Parties of a contractual provision which was not strictly in accordance with the express terms of that provision would amount to an amendment and such amendment could only be enforceable if it was in writing in compliance with Article 34.2 of the Panna Mukta PSC and signed by the President of India pursuant to Article 299 of the Constitution of India. But if that were so, any exercise by a Government representative (here the representative on the MC) of a power conferred on it under a contract duly executed in terms of Article 299 of the Constitution of India which did not comply strictly with the terms of such contract would be unconstitutional and an estoppel could never apply vis‐à‐vis the Government in respect of any contract it has entered into. If that was the case, there would be clear legal authority stating so. However, [the Government] has not referred to any. The simple fact is that the Parties, as is clear from the relevant MC resolutions, had agreed or had come to a common understanding that Development Costs incurred in respect of certain items of works (namely those identified by the Tribunal in the Agreements Case Award and in Issue 12 below) would be fully cost recoverable. [The Government] is merely to be held to its agreement and/or is estopped from contending otherwise.”
“3.18…The problem with this submission is that the question whether res judicata (i.e., the ‘principle in Henderson v Henderson’: see paragraphs 4.9 and 4.12 of the Balance EPOD Award) is a question of procedural law or whether it is a substantive rule of law had not been argued before the Tribunal before it issued the [2021 Award]. It is this question [the Government’s] request for clarification is directed at. Notably, [it] has not shown, either in [its] Application of28 February 2021 or [its] Reply of15 March 2021 , that this question was argued before the Tribunal in the Parties’ respective written and/or oral submissions on the Balance EPOD Agreements Case and thus had to be determined by the Tribunal…It is difficult to see how the Tribunal could now, in response to a purported request for clarification, effectively decide a matter which had not been argued before it in the first place.”
“25…Res judicata and abuse of process are juridically very different. Res judicata is a rule of substantive law, while abuse of process is a concept which informs the exercise of the court's procedural powers. In my view, they are distinct although overlapping legal principles with the common underlying purpose of limiting abusive and duplicative litigation. That purpose makes it necessary to qualify the absolute character of both cause of action estoppel and issue estoppel where the conduct is not abusive. As Lord Keith put it in Arnold v National Westminster Bank plc[1991] 2 AC 93 , 110G, “estoppel per rem judicatam, whether cause of action estoppel or issue estoppel, is essentially concerned with preventing abuse of process.”
