79 3. Pursuant to article V, section 20, and article VI, section 23, of the General Convention, it is only the Secretary-General who has the right to waive the privileges and immunities accorded to officials and experts on mission. In deciding whether such privileges and immunities exist and whether they should be waived, the Secretary-General may take into account the views of the legislative body that appointed the officials or experts on mission. Regulation 1 (f) These regulations are applicable to the Chairman and Vice-Chairman of the International Civil Service Commission and the Inspectors of the Joint Inspection Unit, without prejudice to and in accordance with the statutes of the International Civil Service Commission and the Joint Inspection Unit, which stipulate that these officials perform their functions in respect of the United Nations and other organizations that accept their statutes. [There is no commentary to this provision.] Regulation 2 – Conduct Regulation 2 (a) Officials and experts on mission shall uphold the highest standards of efficiency, competence and integrity. The concept of integrity includes, but is not limited to, probity, impartiality, fairness, honesty and truthfulness in all matters affecting their work and status. Commentary 1. Regulation 2 (a), which describes basic values expected of officials and experts on mission, is similar to staff regulation 1.2 (b). 2. The first sentence of regulation 2 (a) is derived from Article 101, paragraph 3, of the Charter of the United Nations by virtue of affirmatively placing upon officials and experts on mission the obligation to uphold the highest standards of efficiency, competence and integrity. As pointed out in paragraph 4 of the ICSAB report, the concept of integrity includes “honesty, truthfulness, fidelity, probity and freedom from corrupting influences”. Regulation 2 (b) In the performance of their duties, officials and experts on mission shall neither seek nor accept instructions from any Government or from any other source external to the Organization.
