3 Certain judges of the International Court of Justice (ICJ) were particularly prominent in raising this concern. Former ICJ Judge Oda, in particular, was unambiguous in his 1980s criticism of the ICJ chambers procedure (Oda, Shigeru, ‘Further thoughts on the chambers procedure of the International Court of Justice’, in American Journal of International Law (AJIL), Vol. 82, 1988, pp. 556–562Google Scholar) and was somewhat more aggressive in his 1990s critique of the International Tribunal for the Law of the Sea (Oda, Shigeru, ‘The International Court of Justice and the settlement of ocean disputes’, in Collected Courses of the Hague Academy of International Law, Vol. 244, 1993, pp. 127–155Google Scholar). A wider range of fragmentation issues was then discussed at several conferences in the late 1990s, including a 1995 American Society of International Law (ASIL) forum, the Fourth EC/International Law Forum of 1997, and a 1998 New York University/PICT symposium. For proceedings, see Laurence Boisson de Chazournes (ed.), Implications of the Proliferation of International Adjudicatory Bodies for Dispute Resolution, ASIL, 1995; Malcolm Evans (ed.), Remedies in International Law: The Institutional Dilemma, Hart Publishing, Oxford, 1998; and New York University Journal of International Law and Politics, Vol. 31, No. 4, 1999, respectively.

6 Gunther Teubner's theoretical writings focusing on private international law are the main exception. Indeed, in 1992 he had already predicted that should ‘the law of a global society become entangled within sectoral interdependences, a wholly new form of conflicts law will emerge; an “intersystemic conflicts law,” derived not from collisions between the distinct nations of private international law, but from collisions between distinct global social sectors’.

40 Goldblat even finds such practice that pre-dates the birth and codification of international environmental law, with examples including the United States' payment of compensation to Japan for the effects of radioactive fallout from a nuclear explosion it set off in the Pacific in 1954 (though the payment to the crew of the Lucky Dragon was technically made ex gratia, i.e. without admitting responsibility) and to Spain for the radioactive contents of hydrogen bombs that accidentally fell from a US bomber over Palomares, Spain, in 1966, damaging crops and fields.

68 The identification of two distinct approaches, argued for here specifically in relation to environmental treaties and armed conflict, has certain parallels with the ILC's distinction between a subjective and objective test discussed in paragraph 9 of the ILC Report, The Effect of Armed Conflict on Treaties: An Examination of Practice and Doctrine, 1 February 2005, available at: http://untreaty.un.org/ilc/documentation/english/a_cn4_550.pdf (last visited 6 September 2010), esp. paras. 9ff, with the strict treaty law approach ultimately involving an appreciation of the subjective intention of the treaty drafters and the ICJ's approach clearly depending on an objective evaluation of whether the operation of the treaty provision is compatible with the conduct of warfare.

77 Note that, once specific rules had been developed, the lex specialis derogate legi generali rule had a non-neutral application as between the two subsystems of international law, requiring that the specific provisions developed within international humanitarian law apply in place of pre-existing general international environmental law rules on environmental damage (but not in wartime) or general international humanitarian law rules on wanton destruction (but not specifically destruction of the natural environment).

90 Protocol III to the Convention on Certain Conventional Weapons, Geneva, 10 October 1980, available at: http://www.icrc.org/ihl.nsf/FULL/515 (last visited 20 September 2010), Art. 2(4): ‘It is prohibited to make forests or other kinds of plant cover the object of attack by incendiary weapons except when such natural elements are used to cover, conceal or camouflage combatants or other military objectives, or are themselves military objectives’. As can be seen, this provision is heavily compromised by an explicitly broad notion of military objectives, such that it would not even find the US activities in Vietnam in breach.

The General Assembly and the Sixth Committee are the appropriate fora to deal with this subject. The specific competence and role of the International Committee of the Red Cross should be taken into account’.

93 ENMOD Convention, above note 89, Art. I: ‘Each State Party … as the means of destruction, damage or injury to any other State Party’. As noted above, Additional Protocol I expressly applies only to international armed conflict and no environmental damage provision was included in Additional Protocol II, which regulates non-international armed conflict.

Even if norms of precisely this nature are considered to have been the subject of sufficiently constant and widespread state practice with accompanying opinio juris to have become customary, which in the present author's view is doubtful, the persistent objector notion would seem to prevent these rules being applied in relation to certain key militarily active states.

118 Some authors, such as Freeland, Weinstein, and Sharp, consider that other provisions in the ICC Statute – such as those pertaining to genocide or crimes against humanity – may be applicable to acts of wartime environmental damage. The present author does not share this view. Most environmental damage is unlikely to be sufficiently localized to have the effect of deliberately targeting a specific national, ethnical, racial, or religious group and to reach the high threshold rightly imposed by the ICC Statute's genocide provision (Article 4), while crimes against humanity, which generally require ‘great suffering or serious injury to body or to mental or physical health’ (see ICC Statute, Art. 7(1)(k)), at the most only capture attacks against the environment directly causing, with knowledge, substantial human suffering, not simply ‘environmental’ crimes. See Steven Freeland, ‘Crimes against the environment: a role for the International Criminal Court?’, in La Revue Juridique Polynésienne, Hors Série, 2005, pp. 335ff.; Weinstein, Tara, ‘Prosecuting attacks that destroy the environment: environmental crimes or humanitarian atrocities?’, in Georgetown International Environmental Law Review, Vol. 17, 2005Google Scholar; and P. Sharp, above note 105.

119 The scope of this article has been limited to international armed conflict not simply because the relevant international criminal law is restricted to international conflicts (see ICC Statute, Art. 8(2)(b) (chapeau); ICC Preparatory Commission, Elements of Crimes, ICC Doc: ICC-ASP/1/3 (hereafter ‘Elements of Crimes’)), but also to avoid the analysis of a significant further branch of international law – human rights law – and the detailed discussion that its interaction with both international environmental law and international humanitarian law in this context would merit.

120 It should be noted that in defining the scope of her study of Transboundary Damage in general, Xue Hanqin uses four elements of definition which overlap substantially with those outlined here.

This is probably the origin of the use of this word in the ICC Statute. Interestingly, Article 85 of the French version of Additional Protocol I uses ‘lancer une attaque’.
