The Obligation to Undertake an Environmental Assessment in the Jurisprudence of the ICJ: A Principle in Search of Autonomy
Published online by Cambridge University Press: 26 April 2017
Abstract
The practice of carrying out an environmental impact assessment (EIA) has gained strength in international law and jurisprudence, finding application in the case law of the International Court of Justice (ICJ). If, on the one hand, the ICJ has recognized the customary nature of this principle, on the other its application poses a set of challenges, mainly linked to the autonomy of this obligation from other international environmental law norms. More precisely, the obligation at issue has been applied in connection with the due diligence and notification principles, creating uncertainty about its scope, as well as about its substantive or procedural nature. Likewise, the autonomy of the obligation to perform an EIA has been challenged in relation to the definition of the content and scope of the obligation itself, which in turn is linked to the existence of applicable treaty provisions or of soft law. This article discusses the impact of these elements on the reasoning of the Court in the cases at issue, in order to demonstrate how such lack of autonomy can undermine the coherence of the reasoning itself and, therefore, an effective application of the principle.

According to para. 63 of the judgment rendered in 1974, the same kind of conduct by France established the possibility for the applicant to request an examination of the situation if the basis of the judgment “were to be affected” (Nuclear Tests (New Zealand v France), Judgment, 20 December 1974, (1974) ICJ Reports 457 et sqq., at para. 63). This provision was relied upon by New Zealand following the resumption, on the part of France, of nuclear testing in the same region.

As is known, the case concerned the joint construction, by Hungary and the Czech Republic, of a system of locks. Hungary invoked the suspension of the Treaty binding the two States to carry out the activity on the basis of the environmental risks involved (at para. 37).

42 It is to be noted, however, that not all judges concur with this idea. It is the case, for example, that Judge Donoghue, in his separate opinion, states not to be confident that State practice and opinio juris support the existence of such a specific rule (ibid, Separate opinion of Judge Donoghue, at p. 4).
43 As regards the relationship between these two categories of obligations, in the Pulp Mills case, parties posited different conceptions of such a link. Whereas, according to Uruguay, procedural obligations form a means to achieve the respect of substantive ones (Pulp Mills, supra note 32, at para. 73), according to Argentina, a breach of procedural obligations automatically entails a violation of substantive ones (ibid, at para. 72). The Court took an intermediate position in this respect, by arguing that a functional link exists between the two categories of obligations, which can in any event also be seen separately (ibid, at para. 79).

53 According to the definition given by the Seabed Disputes Chamber of the International Tribunal for the Law of the Sea, the due diligence obligation is an obligation of conduct that aims to ensure the prevention of environmental harm. Such an obligation consists not only of the adoption of legislative and administrative measures, but also of undertaking efforts to ensure that private operators comply with these norms (Responsibilities and Obligations of States Sponsoring Persons and Entities with Respect to Activities in the Area, 1 February 2011, at paras. 110–111).
54 The uncertainties relating to the definition of the obligation of due diligence clearly emerge in the separate opinions attached to the Certain Activities and Construction of a Road cases. According to Judge ad hoc Dugard, the duty of due diligence is a standard of conduct required to implement the principle of prevention, which, in turn, is implemented though a number of specific, independent obligations, which include the duty to carry out an EIA (Certain activities, supra, note 36, Separate opinion of Judge Dugard, at paras. 7–9). The autonomy of the obligation to undertake an EIA is instead opposed by Judge Owada, who states this obligation is one element in the “holistic process” that emanates from the obligation of States to use due diligence to avoid environmental harm, “rather than a separate and independent obligation standing on its own under general international law” (ibid, Separate opinion of Judge Owada, at para. 18). In the same sense, see also the opinion of Judge Donoghue, which defines due diligence as the “governing primary norm” (ibid, Separate opinion of Judge Donoghue, at para. 9). As has been underlined, Art. 12 of the Convention on the Law of the Non-navigational Uses of International Watercourses (New York, 21 May 1997, in force 17 August 2014) while imposing a notification duty on State parties, actually falls short of obliging them to conduct an EIA, which has to be included only if “available”. However, it has been suggested that the “due diligence” standard contained in the same Convention places States under an obligation to provide a certain level of information (Alistair Rieu-Clarke, “Notification and Consultation on Planned Measures Concerning International Watercourses: Learning Lessons from the Pulp Mills and Kishenganga Cases” in Ole Kristian Fauchald, David Hunter and Xi Wang (eds), Yearbook of International Environmental Law (Oxford: Oxford University Press) 102 et sqq., 109.

64 It is interesting to note how a similar problem arose in relation to the application of Art. 5.7 of the Agreement on Sanitary and Phytosanitary measures (SPS measures) (allowing Members to adopt a precautionary approach, and therefore to adopt trade-restrictive measures in the absence of scientific certainty) and the general obligation to ensure that SPS measures are based on a risk assessment contained in Art. 5.1 of the Agreement. In an attempt to clarify the relationship between the two provisions, the Appellate Body has affirmed that “Article 5.7 is concerned with situations where deficiencies in the body of scientific evidence do not allow a WTO Member to arrive at a sufficiently objective conclusion in relation to risk” and that the same provision, Art. 5.7 “contemplates situations where there is some evidentiary basis indicating the possible existence of a risk, but not enough to permit the performance of a risk assessment” (United States – Continued Suspension of Obligations in the EC – Hormones Dispute, Report of the Appellate Body, WT/DS320/AB/R, 16 October 2008, at paras. 677–678).

67 See, for example, Art. 19 of the Rio Declaration (supra note 6), according to which “States shall provide prior and timely notification and relevant information to potentially affected States on activities that may have a significant adverse transboundary environmental effect and shall consult with those States at an early stage and in good faith”. See also Art. 15.2(b) of the Protocol on Environmental Protection to the Antarctic Treaty (supra note 12) and Article 14.1(c) and (d) of the Convention on Biological Diversity (supra note 11).
68 Certain activities, supra note 36, Separate opinion of Judge Donoghue, at para. 21.
69 Certain activities, supra note 36, at para. 168 where the Court established that: “the duty to notify and consult does not call for examination by the Court in the present case, since the Court has established that Costa Rica has not complied with its obligation under general international law to perform an environmental impact assessment prior to the construction of the road.”
70 In this regard, see the separate opinion of Judge Donoghue, who excludes that the words of the Court can be read in terms of incorporating national legislation (ibid, Separate opinion of Judge Donoghue, at para. 15). Contra see the opinion of Judge Bhandari, according to whom this possibility is actually allowed, even if the scarcity of guidance from the Court and other sources of international law lead one to think that there are presently no minimum binding standards in this regard (ibid, Separate opinion of Judge Bhandari, at para. 29). An intermediate position is the one held by Judge Dugard, who, on the basis of the works carried out by the ILC, affirms that that same matters are inherent in the nature of an EIA and cannot, therefore, be left to national legislation (ibid, Separate opinion of Judge Dugard, at para. 18). In the sense that the content of the rule must be set by domestic law, see Pierre-Marie Dupuy and Jorge E Viñuales, International Environmental Law (Cambridge: Cambridge University Press 2015) 70.

74 Certain activities, supra note 36, at para. 206. In this regard, the decision of the Court not to find a legal obligation to consult with the public has been defined as “surprising” in the light of the emphasis put by several modern treaties on this point (Cymie R Payne, “Pulp Mills on the River Uruguay” (2011) 105 AJIL 94 et sqq., at 100).
