The Charter of the United Nations does not define the “veto”, and many questions have been raised as to what constitutes a veto. For the purpose of this repertoire it has been established that the veto has been applied if a substantive motion which has received a majority of seven votes has failed of adoption through the negative vote of one or more of the permanent members. Thus only the application of the extraordinary right of a permanent member to overcome a majority (seven) has been considered. Negative votes of permanent members on resolutions which have failed to receive the necessary seven votes have not been listed.
