As promised by my last post on the Sempra Annulment decision, this is a comment on the Enron Annulment decision of 30 July 2010. The decision is fascinating for a number of reasons, but this post shall concentrate on the Committee’s analysis of the “only means” requirement under the customary doctrine of necessity. Whilst highlighting the inherent ambiguity in the application of these words, the Committee’s inquisitorial approach may create more problems than it solves. Accordingly, this post concludes with a rough sketch of logical steps a tribunal may take in applying the “only means” requirements under custom.
I. Background & Findings of the Committee in the Enron Annulment decision
By way of background on investor-State arbitration claims concerning Argentina, please see my last post. The Enron Annulment Committee concluded that the original award, rendered in favour of the Claimant, was to be annulled due to the Tribunal’s failure to apply the applicable customary law as represented by Article 25 of the ILC Articles on the Responsibility of State for Internationally Wrongful Acts and failure to give reasons (paras. 377-8, Enron Annulment). In particular the Committee concluded that the tribunal’s reasoning of the “only means” requirement under Article 25 was entirely insufficient: (emphasis added)
369. The first question concerns the legal definition of the expression “only way” in Article 25(1)(a) of the ILC Articles. The Committee notes that the expression is capable of more than one possible interpretation. One potential interpretation is that it has its literal meaning, such that in the present case, the principle of necessity could be relied on by Argentina if there were genuinely no other measures that Argentina could possibly have adopted in order to address the economic crisis. As Argentina points out, there will almost inevitably be more than one way for a Government to respond to any economic crisis, and if this interpretation were correct, the principle of necessity under customary international law could rarely if ever be invoked in relation to measures taken by a Government to deal with an economic crisis. However, that would not mean that it would not be open to a Tribunal to find that this is the correct interpretation, although there are other interpretations that would be equally open to a Tribunal.
370. For instance, another possible interpretation would be that there must be no alternative measures that the State might have taken for safeguarding the essential interest in question that did not involve a similar or graver breach of international law. Under this interpretation, if there are three possible alternative measures that a State might adopt, all of which would involve violations of the State’s obligations under international law, the State will not be prevented from invoking the principle of necessity if it adopts the measure involving the least grave violation of international law. Under this interpretation, the principle of necessity will only be precluded if there is an alternative that would not involve a breach of international law or which would involve a less grave breach of international law.
371. A second question not addressed by the Tribunal is whether the relative effectiveness of alternative measures is to be taken into account. In adopting measures to safeguard an essential interest, a State may in practice not be in a position to know with certainty whether a given measure will prove to be effective, and reasonable minds may judge that some measures are likely to be more effective than others. For instance, suppose that there are two possible measures that a State might take in order to seek to safeguard an essential interest. One is 90 per cent probable to be 90 per cent effective to safeguard that essential interest, while the other is 50 per cent probable to be 60 per cent effective. Suppose that the former measure would (subject to the potential application of the principle of necessity) be inconsistent with obligations of the State under international law, while the latter measure would not. Would the State be precluded from invoking the principle of necessity if it adopted the former measure, on the basis that there was an alternative available? Or could the State claim that the measure taken was the “only way” that stood a very high chance of being very effective?
372. A third question that is not specifically addressed by the Tribunal is who makes the decision whether there is a relevant alternative, and in accordance with what test? Does the Tribunal determine this at the date of its award, when the Tribunal may have the benefit of knowledge and hindsight that was not available to the State at the time that it adopted the measure in question? Or does the Tribunal determine whether, on the basis of information reasonably available at the time that the measure was adopted, a reasonable and appropriately qualified decision maker would have concluded that there was a relevant alternative open to the State? Or does customary international law recognise that reasonable minds might differ in relation to such a question, and give a “margin of appreciation” to the State in question? In that event, the relevant question for the Tribunal might be whether it was reasonably open to the State, in the circumstances as they pertained at the relevant time, to form the opinion that no relevant alternative was open.
II. Analysis of the Committee’s Annulment approach to “only means”
The Committee’s analysis of the “only means” requirement under Article 25 ILC Articles raises three particular points of interest (sections B-D below). However, this post shall quickly examine the background to this requirement.
A. Background to the “only means” requirement under Article 25
The “only means” requirement is merely one of a number of substantive requirements under Article 25 that ensure that it shall only be rarely available. The ILC Commentaries makes only two points in regard to these words: “the plea is excluded if there are other (otherwise lawful) means available, even if they may more costly or less convenient” (para. (16), Article 25 ILC Commentaries). The first point goes back to Judge Anzilotti’s opinion in the Oscar Chin case (p. 114), the Russian Indemnity case and the Serbian Loans case. The second, that of cost and convenience, is predominantly derived from the Gabčíkovo-Nagymaros Project case, although Ago had considered it in his 8th Report on State Responsibility (para. 14 of the 1980 Report).
Cases provide little guidance on how to treat these two words: “only means”. One may go as far to question its presence in the customary doctrine: the Serbian Loans and Russian Indemnity cases can easily be contrasted (where a very lose formulation of the requirement was considered) with the French Company of Venezuela Railroads case where the strict requirement of alternative means was not considered in upholding the defence in favour of Venezuela.
B. The Value of a Literal Interpretation?
The Enron Annulment Committee recognised Argentina’s argument that if a literal interpretation was to be provided to “only means”, the necessity defence “would rarely if ever be invoked … to deal with an economic crisis” (para. 369, Enron Annulment). Whilst Article 25’s application has always been envisaged as one of rare availability, this does not justify a narrow interpretation of the “only means” requirement. The value of a literal interpretation cannot be evinced to uphold the defence’s exceptionality – or vice versa. Each substantive requirement (e.g. “only means”) of Article 25 needs to be interpreted and applied with its own value.
If one was to follow a literal interpretation of the words “only means” then any alternative, irrespective of its viability and reasonableness, is available to exclude the operation of the necessity defence (see CMS Award, para. 323 onwards). Clearly, the interpretation and application of these words needs to be pragmatic but not overly inclusive (see LG&E Award, para. 257). If only for this reason, the Enron Annulment decision is notable for its willingness to confront head-on the uncertainty of Article 25; a task that most previous tribunals (including the ICJ) have shied away from.
C. Determining what qualifies as an “alternative” means
The Enron Annulment Committee examines the uncertainty of the words “only means”. It does so by identifying factors which may determine what may constitute a relevant alternative means for the purposes of Article 25. Two specific factors are identified: (i) the comparative gravity of the breach induced by the alternative means; (ii) the comparative effectiveness of the alternative means (paras. 370-1). The Committee’s inquisitorial reasoning identifies both of these factors as possible considerations when determining whether a specific alternative means is to be considered relevant for the purposes of Article 25(1)(a) ILC Articles and therefore exclude the necessity defence.
In regard to the first of these, consideration of the comparative gravity of the breach by an alternative means, the Committee goes further than existing law. Current law enunciates the rule identified by the ILC: “the plea is excluded if there are other (otherwise lawful) means available”. The point in parenthesis is to identify as relevant those alternative means which would have been lawful. If such means are identifiable, it is only these means which could potentially exclude the necessity defence. This position is consistent with existing authority on the issue: Judge Anzilotti’s opinion in the Oscar Chin case (para. 7 of the Individual Opinion), Roberto Ago’s 8th State Responsibility Report (para. 14), and the ICJ the in Gabčíkovo-Nagymaros Project case (para. 55) and the ILC Commentaries (para. 15, Article 25 ILC Commentaries).
The Annulment Committee’s analysis on this point of gravity is worrying for two reasons. First, it presumes that, bar jus cogens norm breaches, there are identifiable hierarchical levels of breaches. This is misguided and incorrect. Second, it broadens the range of relevant alternative means that can exclude the necessity defence. Given that precedent only excludes the necessity defence for a State if an alternative legal measure is taken to safeguard its essential interests, the Committee goes further by introducing the possibility that an alternative illegal but less graver measure may exclude the necessity defence. By broadening the spectrum of possibly exclusionary alternatives the Committee’s inquisitorial reasoning, if adopted by other tribunals, would narrow the necessity defence further than its already stringent conditions.
The second factor considered by the tribunal was the relative effectiveness of the alternative measure identified. This is of great importance given that situations of necessity shall always concern grievous circumstances. The effectiveness of the measure to safeguard against such a circumstance is central to the purpose of the necessity doctrine. The most penetrating question posed by the tribunal is whether the necessity defence is precluded if the State pursues a measure which is more effective but illegal, when it possesses the capability to pursue a measure which is legal but far less effective. Formalistically, the presence of the latter should prevent the applicability of the necessity doctrine. Purposefully, the necessity doctrine is aimed at legitimating those measures which a State must take to effectively deal with a situation which threatens its essential interests or its very existence. If the doctrine does not permit the State to take those measures which would best protect it against further chaos (in this case economic chaos) and harm in a particular situation – then the doctrine serves little purpose at all. The need for the measure to adequately and effectively address the “peril” in question is at the heart of the doctrine; for necessity only ceases to operate once the situation requiring attention ceases to be one that threatens an essential interest of the State. The presumption behind this rule is that the measure taken under the necessity doctrine is effective; it does its job of safeguarding the essential interests of the State.
Given the Committee’s identification of each of the two concerns above, it should be clear that at the very least a literal and strict application of the “only means” requirement serves no purpose. Rather in determining what may or may not be a relevant alternative that may preclude the defence a reasonable, practical and empirical approach needs to be taken.
D. Who determines what qualifies as a “relevant alternative” and when?
The Enron Annulment Committee concludes its inquisition into the above question with: “the relevant question for the Tribunal might be whether it was reasonably open to the State, in the circumstances as they pertained at the relevant time, to form the opinion that no relevant alternative was open” (para. 372, Enron Annulment). This statement is not meant as a definitive interpretation (see para. 373, Enron Annulment). It raises two particularly interesting questions.
First is the question of when the determination of the existence of a relevant alternative is made. Quite correctly, the Committee tends to the view that this determination should be examined and evaluated at the time immediately preceding and at the same time as the measures invoking necessity were initiated by the State in question. This should enable an empirical examination of the relevant evidence that the State acted upon at the relevant time. It furthermore prevents hypothesising after the event – the value of hindsight always enables the identification of options that may not have been seen at the time the measure was taken. It is quite clearly improbable that a State is able to identify all of the options available to it in dealing with an “imminent” peril.
Second, is the question of who makes the determination at the relevant time. At the particular relevant time, it is the State that makes any determination of whether the measure is the “only means”. However, it is clearly the tribunal which determines the legality of the State’s determination. The question of who raises two particular questions: (i) if the State makes the determination at the relevant time what steps is it required to take to make this determination; (ii) when the tribunal considers the legality of State’s determination to whom does it defer, if anyone, in determining whether there were relevant alternative measures open to the State.
Turning to (i) – if it is impossible for the State to identify all of the possible alternatives open to it, then it can only undertake reasonable measures towards identifying alternatives. The Committee suggests a move towards a loose due diligence standard in this regard: has the State reasonably determined the lack of other relevant options and in doing so has it taken reasonable steps. This approach shifts the focus towards States compiling detailed and sufficient evidence and a tribunal empirically identifying the steps a State may have taken towards identifying alternatives. The question then becomes: what steps are reasonable enough in a given situation of “grave and imminent peril”? Again one finds oneself devolving into a soft standard and one of uncertainty.
Turning to (ii) – a tribunal may take two possible approaches in determining the legality of the State’s actions and its decision-making process. It may take a reasonable and commonsensical approach to identifying alternatives, or it may seek the standard that an “appropriately qualified decision maker” (para. 372, Enron Annulment) or expert may identify possible alternative measures at the relevant time. The ICJ in the Gabčíkovo-Nagymaros Project case seems to adopt the former option, whilst the original tribunal in Enron and the Annulment Committee seem to defer to the latter option. In a situation of economic necessity, deferral to an economic expert in the identification of a relevant alternative means of dealing with the financial crises is to be expected. However, not only do experts disagree, but they espouse different options at every turn (see CMS Award). Yet, the tribunal prioritised the Claimant’s expert who identified other options available to the Argentine Republic in dealing with the financial crises. This prioritisation of one expert over another, without reason, was criticised by the Annulment Committee (para. 376, Enron Annulment). This raises questions of whether an objective standard as to identifying alternative means exists under Article 25, who should adjudge such alternatives and does a tribunal applying the standard have jurisdiction to review the decision of experts who may identify alternatives.
Based on the uncertainty of the above, I post that a tribunal should take three steps in determining the existence of relevant alternative means.
(i) The tribunal should examine the steps taken by the State, at the relevant time, to identify possible alternatives to the means its chose;
(ii) The tribunal should then examine the reasonableness of the State’s steps in identifying alternative means, given the particular situation (i.e. imminence and level of peril faced);
(iii) The tribunal is then able to shift the burden of demonstrating alternatives to the opposing party; to identify any particular alternative the State should have known and considered at the relevant time.
This is a rough outline based on the holes identified by the Enron Annulment Committee. It aims at removing tribunal hypotheses concerning alternative means and roots it in empirical reality. The third step is novel. Traditionally, the burden of proof for the necessity defence and the “only means” requirement lies with the State seeking to rely on it. However, if carried to its limit, this burden may devolve into the State disproving the applicability of any number of hypothetical alternative means. The purpose of steps one and two would be to enable the State to fulfil its burden reasonably and then only seek to go beyond this once the Claimant is able to identify a specific alternative means which may have been available to the State and should have been known by the State at the relevant time. This in turn also minimises and objectifies the role of experts and resorts back to the question of the evidence the State had, or should have known about, at the relevant time.
This post cannot posit a comprehensive theory answering the problems of uncertainty in the words “only means”. It has, however briefly, examined the positives to be taken out of a damning critique of literal interpretation of necessity’s requirements.
