136. But of the considered view which he subsequently expressed in the 5th edition of The Legal Aspect of Money (Clarendon, Oxford, 1992) 526, referring to '... the overiding principle of "fair and equitable treatment", which, it must be repeated, in turn is perhaps no more than a (welcome) contractual recognition and affirmation of that principle of customary international law which requires States to act in good faith, reasonably, without abuse, arbitrariness, or discrimination.'

141. The Tribunal relied upon Azurix Corp v Argentina (Award) ICSID Case No ARB/01/12 (ICSID, 14 July 2006, Sureda P, Lalonde, & Martens) para 361. However, the Azurix tribunal was interpreting a provision which accorded investors fair and equitable treatment 'and shall in no case be accorded treatment less than required by international law.' Such a provision by its terms sets a floor. In any event the Azurix tribunal found that the applicable standards of custom and treaty 'may in substance be the same' (para 364).
