Abstract

This chapter introduces the topic and scope of this book. MFN clauses frequently appear in IIAs providing an obligation on the host-states to accord the beneficiary states, their nationals and entities, treatment no less favourable than that is accorded to any third state. There are divergent opinions about the scope of MFN clauses in IIAs and about the approaches for determining such scope. IIA MFN clauses are treaty-based obligations as opposed to the principles of customary international law. As a treaty-based obligation, the scope of MFN in IIAs will always depend on how the clauses are drafted and how the adjudicatory forums interpret them. Moreover, drafting of MFN clauses varies from IIA to IIA, and presently, there are more than 3000 IIAs in force. Consequently, the question arises, whether it is feasible to examine the scope of MFN clauses in IIAs. Although the scope of MFN clauses in IIAs is a matter of interpretation, it is possible to clarify their scope to a significant extent by an evaluation of existing jurisprudence on their application. Accordingly, the central thrust of this book is to draw out the proper scope of MFN clauses in IIAs by evaluating the existing jurisprudence, by an analysis of the cases and scholarly literature, together with the text of IIAs. This book also examines issues related to the interpretation of IIAs. To do so, it investigates three sub-issues: firstly, whether there exists a set of uniform principles and rules for interpreting MFN clauses; secondly, whether arbitral tribunals have consistently applied the interpretative principles; and thirdly, whether tribunals should take into account the implications of applying MFN clauses extensively. Besides the general contribution of this book mentioned above, the introductory chapter also demonstrates, why it is important to examine the developing states’ experience in investor-state arbitration regarding the application of MFN.

Notes

  1. 1.

    International Investment Agreement (IIA) is a popular term frequently used in literature to describe a network of bilateral, trilateral, plurilateral and regional investment treaties. International treaties on trade are not included in this network. However, the investment chapters of trade treaties are included. For details, see, United Nations Conference on Trade and Development (UNCTAD), Investment Policy Hub http://investmentpolicyhub.unctad.org/IIA/AdvancedSearchBIT (2013).

  2. 2.

    For details on the features of IIAs, see, UNCTAD, International Investment Agreements: Key Issues, volume 1–3, Karl P Sauvant (eds) (United Nations, 2004–2005), UNCTAD/ITE/IIT/2004/10 (Vol. I), UNCTAD/ITE/IIT/2004/10 (Vol. II), UNCTAD/ITE/IIT/2004/10 (Vol. III).

  3. 3.

    The first IIA was, the Treaty between the Federal Republic of Germany and Pakistan for the Promotion and Protection of Investments (Germany-Pakistan BIT), signed on 25 November 1959, (entered into force on 28 April 1962). For more details on history, see Chap. 2 of this book.

  4. 4.

    UNCTAD, Policy Hub, above n 1. The UNCTAD website demonstrates that presently, amongst the total number of IIAs in force, 2358 IIAs are bilateral investment treaties; for the most recent data, also see, UNCTAD, IIA Issue Note, May 2018, available at http://unctad.org/en/PublicationsLibrary/diaepcbinf2018d1_en.pdf. The issue note mentions that ‘in 2017, countries concluded 18 new IIAs: 9 bilateral investment treaties (BITs) and 9 treaties with investment provisions (TIPs). This brought the size of the IIA universe to 3,322 agreements (2,946 BITs and 376 TIPs), of which 2,638 were in force at year-end.’

    Peter Nunnenkamp, ‘FDI for Development-Assessing the Case for a Multilateral Investment Agreement from the Perspective of Developing Countries,’ 4 Journal of World Investment 585 (2003) at 585–586. On a different level, there are debates as to whether a multilateral investment treaty framework would indeed be beneficial for the developing countries. Nunnenkamp also commented that in strictly economic terms, the case for a multilateral investment agreement is considerably weaker than its proponents are claiming. Even if a multilateral investment agreement can stimulate foreign direct investment capital flow, the developing countries must have reached a minimum level of economic development before they can be benefitted by such foreign direct investment (FDI) inflow.

    Efraim Chalamish, ‘The Future of Bilateral Investment Treaties: A De Facto Multilateral Agreement,’ (2009) 34 Brooklyn Journal of International Law 303 at 305. Chalamish has argued that in the context of the failure of multilateral negotiations, IIAs, through their inclusion of MFN clauses form a complex network that resembles a de facto multilateral agreement.

    Chalamish, above n 15, at 309–310. Chalamish has commented that historically, the capital-exporting developed countries have always dominated the IIA negotiation process while developing countries have very limited negotiation power. Consequently, most of the provisions of IIAs are aligned with the investors’ interests instead of the sovereignty of the developing country.

    Such a stance was taken by the Annulment Committee in, MTD Equity Sdn Bhd. & MTD Chile S.A. v Republic of Chile (MTD v Chile), ICSID Case No. ARB/01/7, Decision on Annulment, dated 21 March 2007, para 64. The Annulment Committee observed that MFN clause could import any more favourable substantive treatment standard from other treaties; also see, the observation by the arbitral tribunal in, EDF International S.A. v Saur International S.A. and Leon Participaciones Argentinas S.A. v Argentina Republic (EDF v Argentina), (ICSID Case No. ARB/03/23, Award, 11 June 2012), paras 936–937. The EDF tribunal stressed that as long as the substantive benefits were concerned, MFN clauses could have extensive application. These cases are reviewed in Chap. 4. In contrast, some more recent arbitral decisions have taken a stance that even within substantive benefits; MFN clauses can apply only within certain boundaries. For example, see, Ickale Insaat Limited Sirketi v Turkmenistan (Ickale v Turkmenistan), ICSID Case No. ARB/10/24, Award, dated 8 March 2016, para 329.

    The first scholarly work that purported to compare the rate of failure of MFN to import substantive benefits in practice with the long prevalent assumption about the unlimited application of MFN to substantive benefits was, David D. Caron and Esme Shirlow, ‘Most-Favoured-Nation Treatment: Substantive Protection’ in Building International investment law: The First 50 Years of ICSID 399, 408–13 (Meg Kinnear, Geraldine R. Fischer, Jara Minguez Almeida, Luisa Fernanda Torres & Mairee Uran Bidegain eds, 2015). More recently, similar opinion is expressed in, Simon Batifort and J. Benton Heath, ‘The New Debate on the Interpretation of MFN Clauses in Investment Treaties: Putting the Brakes on Multilateralization,’ (2017) 111:4 The American Journal of International Law, 873–913. However, Batifort and Heath did not argue for any conclusive stance; similar conclusion is drawn by, Facundo Perez-Aznar, The Use of Most-Favoured-Nation Clauses to Import Substantive Treaty Provisions in International Investment Agreements, (2017) 201 Journal of International Economic Law, 777–805.

    For example, Article I (1) of the 1994 General Agreement on Tariffs and Trade (GATT), above n 7 provides that, ‘with respect to customs duties and charges…any advantage, favour, privilege or immunity granted by any contracting party to any product originating in or destined for any other country shall be accorded immediately and unconditionally to the like product originating in or destined for the territories of all other contracting parties.’ Article I (2), (3) and (4) of GATT 1994 then provide for the exceptions to the MFN obligation contained in Article I (1). These exceptions ensure the non-application of MFN to preferential treatments in force amongst some specific countries listed in GATT Annexures A-F. Article I (2) allows an exception to MFN in regard to historical preferences which were in force at the signing of GATT. There are several other exceptions to the MFN obligation under Article I of GATT. For example, regional integration (GATT 1994, Article XXIV), non-application of MFN to multilateral trade agreements between particular member states (GATT 1994, Article XIII), Generalised System of Preferences (GSP) allowing lower tariff rates for developing countries (Decision of GATT Contracting Parties of 28 November 1979, BISD 26S/203), general exceptions for protecting public morals, life and health (GATT 1994, Article XX), security exceptions (GATT 1994, Article XXI) and exceptions regarding frontier traffic with adjacent countries (GATT 1994, Article XXIV(3). Similar MFN obligations with specific exceptions can be found in the Agreement on Trade Related Aspects of Intellectual Property Law (TRIPS), above n 7, and in the General Agreement on Trade in Services (GATS), above n 7.

    Jarrod Wong, above n 12. Wong commented that even though a bilateral investment treaty imposes reciprocal obligations on both Contracting States, its effects are asymmetrical. The result is that developing countries seek to interpret restrictively any BIT provision that accords rights to the investors and imposes obligations on the host-state, whereas developed countries will read the same provision expansively.

    This chapter discusses ten publicly available arbitral decisions which allowed the application of MFN to substantive benefits. The cases are as follows: MTD Equity Sdn Bhd. & MTD Chile S.A. v Republic of Chile (MTD v Chile), ICSID Case No. ARB/01/7, Award, dated 25 May 2004; EDF International S.A. v Saur International S.A. and Leon Participaciones Argentinas S.A. v Argentina Republic (EDF v Argentina), ICSID Case No. ARB/03/23, Award, dated 11 June 2012; White Industries Australia Limited v The Republic of India (White Industries v India), UNCITRAL, Final Award, dated 20 November 2011; Bayindir Insaat Turizm Ticaret ve Sanayi A.S. v Islaimc Republic of Pakistan (Bayindir v Pakistan), ICSID Case No. ARB/03/29, Award, dated 27 August 2009; Hesham Talaat M. Al-Warraq v The Republic of Indonesia (Al-Warraq v Indonesia), UNCITRAL, Final Award (15 December 2014); Rumeli Telekom A.S. and Telsim Mobil Telekomunikasyon Hizmetleri A.S. v. Republic of Kazakhstan (Rumeli Telekom and Telsim Mobil v Kazakhstan), ICSID Case No. ARB/05/16, Award, dated 29 July 2008; Sergei Paushok, CJSC Golden East Company and CJSC Vostokneftegaz Company v. The Government of Mongolia (Sergei Paushok V Mongolia), UNCITRAL, Award on Jurisdiction and Liability, dated 28 April 2011; Mr. Franck Charles Arif v Republic of Moldova (Franck Charles Arif v Moldova), ICSID Case No. ARB/11/23, Award, dated 8 April 2013; and OAO Tatneft v. Ukraine, UNCITRAL, Award on Merits, dated 29 July 2014; Teinver S.A., Transportes de Cercanías S.A. and Autobuses Urbanos del Sur S.A. v. The Argentine Republic (Teinver v Argentina), ICSID Case No. ARB/09/1, Award, dated 21 July 2017. As mentioned in above n 5, Batifort and Heath identified a total of 12 cases in which MFN succeeded to import more favourable substantive benefits. Their list includes all ten cases listed above. However, Batifort and Heath mentioned two more cases which are not studied in this section, namely, L.E.S.I. S.p.A. and ASTALDI S.p.A. v. République Algérienne Démocratique et Populaire, ICSID Case No. ARB/05/3, Award, dated 12 November 2008, (this decision is written in French, and no authentic English translation is available to this researcher). It must be noted that this chapter only studies cases in which an award or decision is rendered by the arbitral tribunals. The chapter does not study cases which are pending for a decision. It must also be noted that in Teinver v Argentina, application of MFN to procedural prerequisites to arbitration was rejected in the Decision of the Tribunal on Jurisdiction, dated 21 December 2012. The Decision on Jurisdiction will be studied in Chap. 5.

    Chapter 4 also discusses 11 cases in which MFN failed. The cases are as follows: ADF Group Inc. v United States of America (ADF v USA), (ICSID Case No. ARB (AF)/00/1, Award, 9 January 2003); MetalTech Ltd v Republic of Uzbekistan, (ICSID Case No. ARB/10/3, Award, 4 October 2013); Chemtura Corporation v Government of Canada (Chemtura v Canada), UNCITRAL, Award of the tribunal, dated 2 August 2010; Mesa Power Group LLC v Government of Canada (Mesa Power v Canada), UNCITRAL, PCA Case No. 2012-17, Award of the tribunal, dated 24 March 2016; Apotex Holdings Inc. and Apotex Inc. United States of America (Apotex v USA), ICSID Case No. ARB(AF)/12/1, Award, dated 25 August 2014; Ickale Insaat Limited Sirketi v Turkmenistan (Ickale v Turkmenistan), ICSID Case No. ARB/10/24, Award, dated 8 March 2016; UABE Energija Lithuania v Latvia (UABE Energija v Latvia), ICSID Case No. ARB/12/33, Award, dated 22 December 2017; CMS Gas Transmission Company v The Argentine Republic (CMS v Argentina), (ICSID Case No. ARB/01/8, Award, 12 May 2005); GEA Group Aktiengesellschaft v Ukraine (GEA v Ukraine), ICSID Case No. ARB/08/16, Award, dated 31 March 2011; Cargill Incorporated v The United Mexican States (Cargill v Mexico), (ICSID Case No. ARB (AF)/05/2, Award, 18 September 2009); Windstream Energy LLC v Canada (Windstream Energy v Canada), Permanent Court of Arbitration, In the Matter of an Arbitration under Chapter Eleven of the North American Free Trade Agreement And the 2010 UNCITRAL Arbitration Rules, Award, 27 September 2016. Section 3 also studies five cases in which MFN remained undecided in the sense that the tribunals have rendered a decision but left the issue of MFN undecided since it was not necessary for them. The cases are as follows: Gold Reserve Inc. v Bolivarian Republic of Venezuela (Gold Reserve v Venezuela), (ICSID Case No. ARB (AF)/09/1, Award dated 22 September 2014); ATA Construction, Industrial and Trading Company v The Hashemite Kingdom of Jordan (ATA Construction v Jordan), (ICSID Case No. ARB/08/2, Award dated 18 May 2010); William Ralph Clayton, William Richard Clayton, Douglas Clayton, Daniel Clayton and Bilcon of Delaware Inc. v Government of Canada (Bilcon v Canada), UNCITRAL, PCA Case No. 2009-04; Abaclat and others v The Argentine Republic (Abaclat v Argentina), ICSID Case No. ARB/O7/5, Decision on Jurisdiction and Admissibility, dated 4 August 2011; Gemplus S.A., SLP S.A., Gemplus Industrial S.A. de C.V. and Talsud S.A. v The United Mexican States (Gemplus v Mexico), (ICSID Case No. ARB (AF)/04/03 and ARB (AF)/04/4, Award, 16 June 2010).

    It must be noted that the cases studied in Chap. 4 do not constitute any exhaustive list of cases in which MFN has failed. However, the list of cases in which MFN succeeded to import substantive benefits from other IIAs is exhaustive. More explanation on the process of case selection is given in Chap. 4.

  102. 102.

    This author has identified the cases by an extensive research and believes that they include all publicly available decided cases until 2018 in which MFN was applied to bypass procedural prerequisites to arbitration. Websites of UNCTAD Investment Policy Hub and ITALAW are heavily relied on to identify the cases. This chapter does not review any pending case. It reviews cases in which the tribunals have rendered a decision. In most of the cases, Argentina was the respondent host-state which is a coincidence and may represent the fact that a large volume of investor-state arbitral proceedings were initiated against Argentina. For details on cases involving Argentina in general, see, UNCTAD, Investment Policy Hub  http://investmentpolicyhub.unctad.org/ .

    The cases in which MFN succeeded as discussed in this chapter are as follows: Emilio Agustin Maffezini v the Kingdom of Spain (Maffezini v Spain), ICSID Case No. ARB/97/7, Decision of the Tribunal on Objections to Jurisdiction, dated 25 January; Siemens A.G. v The Argentine Republic (Siemens v Argentina), ICSID Case No. ARB/02/8, Decision on Jurisdiction, dated 3 August 2004; Hochtief AG v The Argentine Republic (Hochtief v Argentina), ICSID Case No. ARB/07/31, Decision on Jurisdiction, dated 24 October 2011; Suez, Sociedad General de Aguas de Barcelona S.A. and Vivendi Universal S.A. v The Argentine Republic (Suez v Argentina), ICSID Case No. ARB/03/19, and AWG Group Ltd. v the Argentine Republic (AWG v Argentina), In the Arbitration under the Rules of UNCITRAL, Decisions on Jurisdiction dated 3 August 2006; National Grid PLC v The Argentine Republic (National Grid v Argentina), (UNCITRAL) Decision on Jurisdiction, 20 June 2006; Impergilo S.p.A v Argentina (Impergilo v Argentina), ICSID Case No ARB/09/1, Decision on Jurisdiction, dated 21 December 2012; Camuzzi International S.A. v the Argentine Republic (Camuzzi v Argentina), ICSID Case No. ARB/3/2, Decision on Objections to Jurisdiction dated 11 May 2005; Gas Natural SDG, S.A. v.

    The cases in which MFN failed as discussed in this chapter are as follows: Wintershall Aktiengesellschaft v the Argentine Republic (Wintershall v Argentina), ICSID Case No. ARB/04/14, Award, dated 8 December 2008; Daimler Financial Services AG v the Argentina Republic (Daimler v Argentina), ICSID Case No. ARB/05/1, Award on Jurisdiction, 22 August 2012; ICS Inspection and Control Services Limited (United Kingdom) v the Argentine Republic (ICS Inspection v Argentina), PCA Case No. 2010-9, Award on Jurisdiction, 10 February 2012; Kilic Insaat Ithalat Ihracat Sanayi Ve Ticaret Anonim Sirketi v Turkmenistan (Kilic v Turkmenistan), ICSID Case No. ARB/10/1, Award, dated 2 July 2013.

  103. 103.

    This author, by an extensive research, has identified 26 publicly available investor-state arbitral decisions which have rejected or accepted application of MFN to various dimensions of arbitral jurisdiction until 2018. According to the knowledge of this researcher, these are all of the publicly available decisions on this issue. However, pending cases are not studied. This chapter only studies cases in which tribunals have rendered a decision or Award.
