This article argues that the International Court of Justice's (ICJ) account of the customary law of environmental impact assessment (EIA) is incomplete. While acknowledging the role of the harm prevention principle in formulating the customary obligation to conduct EIAs, the ICJ has ignored the duty to cooperate, notwithstanding the latter duty's equally strong standing in international environmental law. Ignoring the duty to cooperate pushes the court towards a formal and sequential understanding of EIA, which undervalues the centrality of notice and consultation in EIA. In effect, viewed through the harm prevention lens alone, EIA is largely understood in instrumental and technical terms; whereas, if the duty to cooperate is brought back in, EIA's deliberative and ‘other-regarding’ nature is more clearly seen. This, in turn, recognises the normative and political role of EIA in structuring State interactions respecting environmental disputes.

For a recent discussion of the status of EIA in international law, see International Law Commission (ILC) ‘Third Report on the Protection of the Atmosphere’ (25 February 2016) UN Doc A/CN.4/692, 20–33; see also Craik, N, ‘Principle 17: Environmental Impact Assessment’ in Viñuales, J (ed), The Rio Declaration on Environment and Development: A Commentary (Oxford University Press 2015) 451Google Scholar.

5 This view of EIA is often referred to as the comprehensive rationality model, as it is rooted in administrative decision-making models that focuses on expert managers gathering and analysing a wide range of salient information about a policy decision to direct their discretion. The predominant assumption is that optimal decisions are possible, with sufficient information and expertise. In relation to EIA, see discussion by Karkkainen, B, ‘Towards a Smarter NEPA: Monitoring and Managing Governments Environmental Performance’ (2002) 102 ColumLRev 903Google Scholar.

6 There remain different understandings of the political models that may underpin EIA processes. See eg Taylor, S, Making Bureaucracies Think: The Environmental Impact Statement Strategy of Administrative Reform (Stanford University Press 1984)Google Scholar (viewing EIA as a process for facilitating political bargaining within pluralist democratic structures). EIA has also often been viewed in more deliberative terms; see Craik, N, ‘Deliberation and Legitimacy in Transnational Environmental Governance: The Case of Environmental Impact Assessment’ (2007) 38 Victoria University Wellington Law Review 381CrossRefGoogle Scholar; and Poisner, J, ‘A Civic Republican Perspective on the National Environmental Policy Act's Process for Citizen Participation’ (1996) 26 EnvLaw 53Google Scholar.
