Artikel 20

1. Inasmuch as the privileges and immunities provided for in this Agreement are granted in the interests of the good administration of justice and not for the personal benefit of the individuals themselves, the competent authority has the right and the duty to waive the immunity in any case where, in its opinion, the immunity would impede the course of justice and can be waived without prejudice to the administration of justice.
2. For this purpose, the competent authority in the case of agents, counsel and advocates representing or designated by a State which is a party to proceedings before the Tribunal will be the State concerned. In the case of other agents, counsel and advocates, the Registrar, experts appointed under article 289 of the Convention and witnesses, experts and persons performing missions, the competent authority will be the Tribunal. In the case of other officials of the Tribunal, the competent authority will be the Registrar, acting with the approval of the President of the Tribunal.
