4. Principle 23: ‘Theenvironmentandnaturalresourcesofpeopleunderoppression, domination and occupation shall be protected.’

Principle 24: ‘Warfare is inherently destructive of sustainable development. States shall therefore respect international law providing protection for the environment in times of armed conflict and cooperate in its further development as necessary.’

Principle 25: ‘Peace, development and environmental protection are interdependent and indivisible.’ (UN Doc. A/CONF.151/26 (Vol. I)).

5. Par. 39.6 (a) ‘Measures in accordance with international law should be considered to address, in times of armed conflict, large-scale destruction of the environment that cannot be justified under international law …’

The roots of a cultural norm which protects the environment in the context of war is traceable back to ancient times, with proscriptions on the destruction of orchards and the poisoningof wells, see Best, G., ‘The Historical Evolution of Cultural Norms Relating to War and the Environment’, in A, Westing, ed., Cultural Norms, War and the Environment (1988) p. 18, at p. 24 et seqGoogle Scholar.

7. Law of War is used broadly in this article to encompass all aspects of military activity :jus ad bellum, being the law on the use of force in general, i.e., the legality of the military campaign as a whole; jus in bello, being the rules governing the waging of the conflict; and the legal framework of arms control. The focus of this article will be mainly, but not exclusively, on jus in bello and the law of arms control.

See Meron, T., Human Rights and Humanitarian Norms as Customary Law (1989) at p. 188 et seq.Google Scholar, for a survey of scholarly and judicial opinion on obligations erga omnes in general. In Barcelona Traction, ICJ Rep. (1970) at p. 32, the International Court of Justice described such obligations: ‘In particular, an essential distinction should be drawn between the obligations of a State towards the international community as a whole, and those arising vis-à-vis another State in the field of diplomatic protection. By their very nature the former are the concern of all States. In view of the importance of the rights involved, all States can be held to have a legal interest in their protection; they are obligations erga omnes.’

In addition, Art. 19(3)(d) of the International Law Commission (hereafter, ILC) Draft Articles on State Responsibility deems an international crime to be committed when there is ‘a serious breach of an international obligation of essential importance for the safeguarding and preservation of the human environment, such as those prohibiting massive pollution of the atmosphere or of the seas’, ILC (1976) Vol II, Part 2. (UN Doc. A/31/10) p. 95 et seq. In the context of armed conflict see the ILC's commentary on Art. 26 of the Draft Code of Crimes Against Peace and Security of Mankind, Report of ILC on the Work of its 43rd Session, GAOR 46th Session, Supp. No. 10 (UN Doc. A/46/10). Art. 26 attaches criminal responsibility to those who wilfully cause ‘widespread, long-term, and severe’ damage to the environment. See also Report of the First ICRC Meeting which concluded that a general interest exists in preserving the natural environment beyond that of the belligerents.

118. The exception, perhaps, is the Preamble to the UN Weapons Convention, which suggests that the prohibition in Art. 35(3) is part of general international law. But the significance of this should not be overstated for two reasons: this statement appears in the Preamble rather than the main text and, other than France, no major Western military powers have become Parties to the Convention. It should also be noted that at signature of the UN Weapons Convention, France entered a reservation that expressly limited the legal effect of Art. 35(3) to Parties to Additional Protocol I.

119. For example, the behaviour of the belligerents in the Iran-Iraq war, noted in Greenwood, C., ‘Customary Law Status of the 1977 Geneva Protocols’Google Scholar, in A. Delissen and G. Tanja, op. cit. n. 115, at p. 101. This is not dispositive of the issue, however, since the customary law of war does not seem to be generally dependant on actual State behaviourduring wartime for its legal status; compliance tends to be the exception rather than the rule.

133. It has been argued that Iraq is nonetheless responsible for breaching the terms of the Convention by virtue of being a signatory to ENMOD under Art. 18 of the 1969 Vienna Convention on the Law of Treaties, 1155 UNTS 331, which provides that signatories must not engage in acts which defeat the object and purpose of a treaty (see Goldblat, op. cit. n. 129). Contra, Fauteaux, loc. cit. n. 58, who argues persuasively that this argument is misconceived for two reasons: (1) this provision is considered a new developmentof international law, i.e., is not customary international law – therefore since the Vienna Convention entered into force after Iraq signed ENMOD, that rule was not in existence; and (2) in any event, Iraq has not signed the Vienna Convention.

175. Note that the original Australian proposal on environmental protection included declaring violations as ‘grave breaches’ (see CDDH/III/60 of 19 March 1974). The ICRC argue that while not directly a grave breach, such acts may be part of grave breaches of other acts (see ICRC, Protection of the Environment …, op. cit. n. 160, at p. 8). An example might be the targeting of nature reserves which are non-defended localities or demilitarized zones (Art. 85(3)(d)) – see text accompanying n. 183, infra. Note, however, that Art. 22(2)(d) of the ILC Draft Articles on Crimes Against Peace and Security of Mankind is expressed in identical terms as Art. 35(3) of Additional Protocol I, breach of which is considered an exceptionally serious war crime (Report of the ILC on the Work of its 43rd Session, GAOR 46th Session, Supp. No. 10 (A/46/10)).

216. Scholarly opinion on this is split. There are those who argue that the law is plainly clear, that nuclear weapons are illegal, e.g., Meyrowitz, E.L., ‘The Laws of War and Nuclear Weapons’, in Miller, A.S. and Feinrider, M., eds., Nuclear Weapons and the Law (1984) p. 19Google Scholar. Others argue that the law is also clear, and that it does not prohibit nuclear weapons, e.g., US Dept. of Army, The Law of Land Warfare, FM 27–10 (1956) para. 113Google Scholar; Stein, E., ‘Impact of New Weapon Technology on International Law’, 133 Hague Receuil (1971-II) p. 291.Google Scholar Most scholars, however, are of the view that the law is uncertain and legality must be judged on a case-by-case manner, e.g., McCoubrey, H., International Humanitarian Law (1990) p. 166Google Scholar; Shaw, M., ‘Nuclear Weapons in International Law’, in Polgany, I., ed., Nuclear Weapons and International Law (1987) p. 1, at pp. 16–18Google Scholar; and Singh, N. and MacWhinney, E., Nuclear Weapons and Contemporary International Law, 2nd edn.
