44 occasion, OHCHR may invite a member to participate in an event such as a panel discussion of the Human Rights Council or an OHCHR-sponsored seminar, either as representative of the treaty body or in an independent capacity. Such events can be useful to ensure synergies between the work of treaty bodies and other human rights bodies and mechanisms, such as the special procedures. Once a year, normally in June, the Chairs of all treaty bodies hold a joint meeting for five working days. Generally speaking, the meeting provides a forum for the Chairs to discuss their work and consider ways to make the treaty body system more effective. The agenda for the meeting changes from year to year but typically includes issues such as the streamlining and overall improvement of the reporting procedure, harmonization of methods of work, follow-up to world conferences and joint statements. The meeting is an official meeting of the United Nations and the Secretary-General transmits its report to the General Assembly. C. Working with OHCHR All treaties stipulate that the Secretary-General must provide the treaty bodies with the necessary facilities and resources for their work. As a result, the SecretaryGeneral has designated OHCHR as the secretariat of the 10 treaty bodies. In practice, the secretariat’s work is carried out in the Human Rights Treaties Division of OHCHR. The relationship between OHCHR and the treaty bodies has evolved over the years and can today be described as a genuine partnership. OHCHR provides direct support for treaty body sessions and visits but also assists the treaty bodies in many other ways, for example, through its field presences and its research capacity, by raising the work of the treaty bodies in the universal periodic review and through advocacy by the High Commissioner. In turn, the work of the treaty bodies is one of the fundamental pillars of the work of the High Commissioner and OHCHR, by providing expert and authoritative clarifications of treaties and country analyses and recommendations that provide an objective guide for the Office’s work. For example, the concluding observations of treaty bodies are taken into account in the formulation of the OHCHR quadrennial management plans. Two other parts of the United Nations Secretariat also provide direct support to the treaty bodies: the Division of Conference Management at the United Nations Office at Geneva (UNOG) houses the sections responsible for conference services, editing and translation of documents as well as interpretation; and the United Nations Information Service at UNOG provides information coverage of the treaty bodies’ public meetings.
