Practice Relating to Rule 73. Biological Weapons
Côte d’Ivoire’s Teaching Manual (2007) provides in Book IV (Instruction of heads of division and company commanders):
II.1.7. Bacteriological weapons
Bacteriological/biological means are prohibited. States do not have the right to produce, stockpile and use biological weapons. Bacteriological and biological weapons are prohibited because they cause superfluous injury and unnecessary suffering and can affect the civilian population without distinction.
In 2015, in a statement during the meeting of States Parties to the Biological Weapons Convention made on behalf of the Member States of the Non-Aligned Movement that are States Parties to the Biological Weapons Convention, including Côte d’Ivoire, and other States Parties to the Biological Weapons Convention, the permanent representative of the Islamic Republic of Iran stated:
The Group would like to re-emphasize its position as reflected in the Tehran final document of the NAM [Non-Aligned Movement] Summit, as reiterated by the NAM XVII Ministerial Conference held on 26–29 May 2014 , Algers, Algeria in which:
“The Ministers of NAM States Parties to the  Biological and Toxin Weapons Convention (BTWC) reaffirmed that the possibility of any use of bacteriological (biological) agents and toxins as weapons should be completely excluded, and the conviction that such use would be repugnant to the conscience of humankind. …
We recognize the importance of the BWC [Biological Weapons Convention] and its role in the total ban on all biological and toxin weapons.
In 2015, in a statement during the meeting of States Parties to the Biological Weapons Convention, the Director of Armaments of the Ministry of Defence of Côte d’Ivoire stated:
The use of chemical and biological weapons in different conflicts around the world has shown the extent of the horror it represents. The prohibition of their use in 1925 marks the beginning of a collective realization regarding their effects on civilian populations and on combatants.
The innovation brought by the [1972 Biological Weapons] Convention in the management and establishment of a non-discriminatory ban regime among States Parties is a determining factor that weighed in favour of Côte d’Ivoire’s accession. …
… [I]n its 8 July 2015 session, the Council of Ministers adopted the draft law authorizing the President of the Republic to proceed with accession of the State of Côte d’Ivoire to the Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on Their Destruction, [of 10] April 1972. Moreover, according to the procedure in force, the National Assembly, in its 27 November 2015 session, authorized the President of the Republic to ratify the Biological Weapons Convention. In the coming days, Côte d’Ivoire will move from being a signatory to being a State Party to the Biological Weapons Convention.
In this regard, my delegation requests the support of all the States Parties for the successful implementation of the new provisions resulting from our accession to this new instrument, the humanitarian importance of which no longer needs to be demonstrated.
