UN General Assembly
1972

101. Ever since 1945, when our Organization was created at the San Francisco Conference, Mexico has advanced serious reservations on the system adopted for the membership and the voting procedure of the Security Council, that organ to which the Charter has entrusted primary responsibility for the maintenance of international peace and security. Since the amendment which we proposed at that time in the appropriate Committee of the Conference was not adopted, Mexico stated for the record that it had decided to accept the text of Article 23 of the Charter because it interpreted that Article as an implicit application of the rule of law that there is a connection between powers and obligations which leaves intact the basic principles of the equal rights of all States.
