I am grateful to the UCL LLM class of International Law of Foreign Investment for clarifying my thinking on some of these matters.
A natural reaction to such an elegant and erudite article is to offer unqualified praise to its author. While not easily, this reaction should be resisted, as likely to lead to an uninspiring symposium contribution. Therefore, while fully acknowledging the great merit of the argument, I will focus instead on three points where I find the article less than entirely persuasive: (1) the analytical perspective of hybrid theory; (2) the application of law of State responsibility in investment arbitration, as per
Italy v Cuba; and (3) the operation of inter-State investment arbitration, as per
Ecuador v US. (It is only fair to say that there are very few points on which I actually disagree with Anthea Roberts, therefore I will be mostly clutching at exaggerated straw-mannish arguments.)
I. Depoliticisation, fictions, hybrids, and banks of fog
I will start with a trite, but hopefully not an entirely irrelevant observation. Contemporary international lawyers, unlike the lawyers of previous generations, are in possession of a reasonably complete set of rules and vocabulary on sources and responsibility in international law, which should not easily be thought to be inadequate for articulating and addressing our concerns. The different concepts and perspectives that are sometimes introduced into the legal arguments instead may be helpful, but they can also be superfluous or misleading. In investment arbitration, one example of what I have in mind is ‘depoliticisation’: a concept that (at its best) means everything for everybody, with little independent analytical value, but at its worst may be significantly misleading, erroneously suggesting with significant persuasive force that certain positive rules have or have not been created, or certain legal solutions would or would not fit the existing regime (I have contributed my two pennies
here, and it seems to me that Roberts would agree, see pp 11-6). Another example, also referred to in the article (pp 32-3, 38-9), is ‘fiction’ (as ‘the fiction of diplomatic protection’). It may be that I am missing something here, but (even after rereading the leading article on the issue by
Annemarieke Vermeer-Künzli) it is not obvious to me that the dutiful citations to ancient writers and cases add much to the most basic of propositions: States can create primary obligations and secondary rules of admissibility with any content whatsoever, that is precisely what they have done with (respectively) rules addressing treatment of their nationals and diplomatic protection, and there is little more to it.
