This contribution examines the legal merit of the Decision Addressing the Treat from
Chemical Weapons, adopted by the 89th Session of the General Conference of the Organization for the Prohibition of Chemical Weapons (‘opcw’) on 27 July 2018. While relating to matters of high political importance, this Decision still raises important issues of the constitutionality of international organizations’ use of their delegated powers. This contribution pursues the detail of this matter, by focusing, among others, on the scope of the opcw’s authority under the Chemical Weapons Convention and the relationship between the opcw and the United Nations.
