The Conventional Weapons Convention: Underlying Legal Principles
Neither the Convention on Prohibitions or Restrictions on the Use of Certain Conventional Weapons Which May be Deemed to be Excessively Injurious or to have Indiscriminate Effects, adopted in Geneva on 10 October 1980, nor the Protocols annexed to it specify in their operative parts the principles on which the prohibitions and restrictions rest. Such principles are, however, found in the preamble to the Convention.Four of the twelve preambular paragraphs are relevant here. They list: the “general principle of the protection of the civilian population against the effects of hostilities”; the principle “that the right of the parties to an armed conflict to choose methods or means of warfare is not unlimited”; the ban on “the employment in armed conflicts of weapons, projectiles and material and methods of warfare of a nature to cause superfluous injury or unnecessary suffering”; and the fact that it is prohibited “to employ methods or means of warfare which are intended, or may be expected, to cause widespread, longterm and severe damage to the natural environment.” The fifth paragraph reiterates the well-known Martens clause, in the formulation accepted for Article 1, paragraph 2, of Additional Protocol I of 1977.
