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. Geneva, 10 October 1980.
The High Contracting Parties,
' Recalling ' that every State has the duty, in conformity 
with the Charter of the United Nations, to refrain in its international 
relations from the threat or use of force against the sovereignty, territorial 
integrity or political independence of any State, or in any other manner 
inconsistent with the purposes of the United Nations.
' Further recalling ' the general principle of the protection 
of the civilian population against the effects of hostilities,
' Basing themselves ' on the principle of international law 
that the right of the parties to an armed conflict to choose methods or means of 
warfare is not unlimited, and on the principle that prohibits the employment in 
armed conflicts of weapons, projectiles and material and methods of warfare of a 
nature to cause superfluous injury or unnecessary suffering,
' Also recalling ' that it is prohibited to employ methods or 
means of warfare which are intended, or may be expected, to cause widespread, 
long-term and severe damage to the natural environment,
' Confirming their determination ' that in cases not covered 
by this Convention and its annexed Protocols or by other international 
agreements, the civilian population and the combatants shall at all times remain 
under the protection and authority of the principles of international law 
derived from established custom, from the principles of humanity and from the 
dictates of public conscience,
' Desiring ' to contribute to international détente, the 
ending of the arms race and the building of confidence among States, and hence 
to the realization of the aspiration of all peoples to live in peace,
' Recognizing ' the importance of pursuing every effort which 
may contribute to progress towards general and complete disarmament under strict 
and effective international control,
' Reaffirming ' the need to continue the codification and 
progressive development of the rules of international law applicable in armed 
conflict,
' Wishing ' to prohibit or restrict further the use of 
certain conventional weapons and believing that the positive results achieved in 
this area may facilitate the main talks on disarmament with a view to putting an 
end to the production, stockpiling and proliferation of such weapons,
' Emphasizing ' the desirability that all States become 
parties to this Convention and its annexed Protocols, especially the militarily 
significant States,
' Bearing in mind ' that the General Assembly of the United 
Nations and the United Nations Disarmament Commission may decide to examine the 
question of a possible broadening of the scope of the prohibitions and 
restrictions contained in this Convention and its annexed Protocols,
' Further bearing in mind ' that the Committee on Disarmament 
may decide to consider the question of adopting further measures to prohibit or 
restrict the use of certain conventional weapons,
Have agreed as follows:

represented at the conference may participate fully in such consideration. Any 
additional protocols shall be adopted in the same
manner as this Convention, shall be annexed thereto and shall 
enter into force as provided in paragraphs 3 and 4 of Article 5 of this 
Convention. (c) Such a conference may consider whether provision should be made 
for the convening of a further conference at the request of any High Contracting 
Party if, after a similar period to that referred to in subparagraph 3 (a) of 
this Article, no conference has been convened in accordance with subparagraph 1
