Restrictions on the use of force at sea: An environmental protection perspective

Published online by Cambridge University Press:  04 September 2017

Abstract

The restrictions on the use of force at sea exist in different branches of international law: the law of the sea and environmental law, mainly applicable during peacetime, and international humanitarian law (IHL), as the law applicable in times of armed conflict. Different rules from these areas must be compared and analyzed to determine the common principles applicable to restricting the use of force at sea for the purposes of environmental protection. Taking into account the particular problems of protecting the marine environment in the context of the use of force, the law of the sea and international environmental law should be applied to restrict means and methods of using force at sea during armed conflict. The detailed concepts and approaches in the law of the sea and environmental law may complement IHL, and the precautionary principle of international environmental law should be triggered to address the lacunae in IHL protecting the marine environmental during armed conflict.

21 A very rare example in this respect is that the United Kingdom blockaded the Port of Beira of Mozambique, pursuant to Resolution 221 of the UN Security Council, as the port was used to transport oil to support the Smith regime in Rhodesia (now Zimbabwe). Two Greek ships, Joanna V and Manuela, were visited and examined when they sought to break the blockade, and a French tanker, Artois, was shot on the bow for violating the prohibition against importing oil.

44 Articles 35(3) and 55(1) of AP I prohibit not all conditions, but those conditions attached to “long-term, widespread and severe” damage to the environment. See AP I, Arts 35(3), 55(1).

45 Besides the condition of military objectives, in the view of the committee established to review the North Atlantic Treaty Organization (NATO) military operations in the Federal Republic of Yugoslavia in 1999, Articles 35(3) and 55 of AP I only cover very significant damage. The adjectives “widespread, long-term, and severe” used in AP I are joined by the word “and”, meaning that this is a triple, cumulative standard. See Final Report to the Prosecutor by the Committee Established to Review the NATO Bombing Campaign against the Federal Republic of Yugoslavia, June 2000, para. 15, available at: www.icty.org/x/file/About/OTP/otp_report_nato_bombing_en.pdf. Meanwhile, there is a critical appraisal of the above assessment which holds that the Committee's report shows a poor grasp of legal concepts, and deviates from well-established case law of the International Criminal Tribunal for the former Yugoslavia.

50 One line of thought focused on the obligation of “care” in Article 55(1) of AP I holds that the real gem hidden among those provisions is not the prohibition of means and methods causing widespread, long-term and severe damage in Article 35(3), but the obligation on States Parties to take care to protect the environment against such harm.
