70 ANNEX III Regulations Governing the Status, Basic Rights and Duties of Officials other than Secretariat Officials, and Experts on Mission I. INTRODUCTION 1. Article 105, paragraph 3, of the Charter of the United Nations empowers the General Assembly to make recommendations with a view to determining, inter alia, the privileges and immunities of officials of the Organization or to propose conventions to Member States for this purpose. The Assembly did so by adopting the Convention on the Privileges and Immunities of the United Nationsa on 13 February 1946 (hereinafter called “the General Convention”). 2. The United Nations has persons performing full-time services for it, at the direction of its legislative organs, who are not staff. For example, article 13 of the statute of the Joint Inspection Unit (approved by the General Assembly in its resolution 31/192 of 22 December 1976) provides that the Inspectors shall have the status of officials of the Organization but shall not be staff members. In addition, pursuant to article V, section 17, of the General Convention, the Secretary-General has specified and submitted to the Assembly proposals that a number of persons who occupy certain positions within the Organization be accorded privileges and immunities under articles V and VII of the General Convention, even though they are not staff members. Those persons are the presiding officers of United Nations organs performing functions for the Organization on a substantially full-time basis (for example, the Chairman of the Advisory Committee on Administrative and Budgetary Questions and the Chairman and Vice-Chairman of the International Civil Service Commission). Those officials are not in a separate category under the General Convention, but their names are submitted by the Secretary-General to the host country together with those of Secretariat officials who are staff members. These persons have been consistently referred to by the General Assembly as “officials other than Secretariat officials”. 3. Experts on mission may be retained by way of a contract known as a consultant contract, which sets out the terms of their appointment and the tasks that they must discharge. Other individuals may have the status of experts on mission, even though they do not sign a consultant contract, if they are designated by United Nations, Treaty Series, vol. I, No. 4, p. 15. a
