The idea of investment treaty arbitration as public law is in tension with the concept of international law as a law between representative public agencies. This concept of international law is valuable for its capacity to progress a broad range of public policy aims in an integrated and coordinated manner, including aims extending beyond the economic sphere such as international social, environmental, cultural and related aims. The probable effect on this concept of international law of a radical ‘internationalized public law’ approach to investment treaty arbitration requires further thought, especially with regard to the potential implications of recognizing investor rights under international law.

6 Van Harten (n 5) 4, observing that ‘the system's crucial importance is that – unlike any other form of international arbitration – it is a method of public law adjudication, meaning that it is used to resolve regulatory disputes between individuals and the State as opposed to reciprocal disputes between private parties or between States.’ Emphasis original.

27 We may note the remarks of the Tribunal in Toto Construzioni Generali S.P.A. and Republic of Lebanon, ICSID Case No ARB/07/12, Award of June 7, 2012 that ‘[t]he fair and equitable treatment standard of international law does not depend on a perception of the frustrated investor, but should use public international law and comparative domestic public law as a benchmark’ para 166. In Total S.A. v Argentine Republic the Tribunal began by observing that it is generally relevant to consider what will constitute ‘fair and unfair conduct by domestic public authorities in respect to private investors and firms in domestic law’. Total S.A. v Argentine Republic ICSID Case No ARB/04/1, Decision on Liability of 27 December 2010, para 111, cited in Toto, para 166. The Tribunal then referred to ‘a standard of reasonableness and proportionality’ in determining compliance with the requirement for fair and equitable treatment. Paras 123, 309(h). One earlier 1995 case is also interesting, precisely because it seems the arbitrators turned to domestic administrative law to determine the case because they did not view their task as being to apply the investment treaty as a public international law instrument. As discussed by Jarrod Hepburn, ‘Saar Papier v Poland: Comparative Public Law and the Second-Ever Investment Treaty Award’ <www.ejiltalk.org> 3 February 2015.

67 Occidental Petroleum Corporation, Occidental Exploration and Production Company v Ecuador, ICSID Case No ARB/06/11, Award of 5 October 2012, para 417. The concept of proportionality was the pivot of the Tribunal's findings that Ecuador had failed to afford fair and equitable treatment to Occidental's investment (paras 384–452), conduct also tantamount to expropriation (paras 453–455), leading to an award against Ecuador of US$1.7bn. The Tribunal cited at length the evidence that Ecuador's law and Constitution specifically required proportionate treatment, paras 396–401, 422 and 427, additionally citing past awards of arbitral tribunals where reference was made to proportionality. This evidence included the Tribunal's reliance on the statement of expert witness Judge Schwebel on proportionality as one of various considerations in the context of fair and equitable treatment in MTD Equity SDN. BHD. and other v The Republic of Chile, ICSID Case No ARB/01/7 (25 May 2004), para 109, cited in Occidental at para 405; and the controversial decision in Tecmed S.A. v The United Mexican States, ICSID Case No ARB (AF)/00/2 (29 May 2003). The Occidental Tribunal did not frame proportionality as a proposed general principle of law, but made the less specific statement that it had no doubt the principle was applicable as a matter of general international law. ibid, para 427.

112 Part Two of the Articles, dealing with the content of State responsibility, is written without prejudice to any such rights. Art 33(2) of the ILC Articles, above n 158, states that ‘This Part is without prejudice to any right, arising from the international responsibility of a State, which may accrue directly to any person or entity other than a State’. See also Commentary to art 28, para (3), Crawford, above n 108, 193, and Commentary to Chapter I of Part II, General Principles, para 2, Crawford, above n 108, 192.
