A/HRC/12/47 page 9 recommendations contained in the UPR reports in future communications. It was noted that the UPR process would be subject to review in the context of the review of the Human Rights Council by the General Assembly. 30. Participants also discussed challenges, noting that UPR was complementary to and not a substitute for existing mechanisms. Its outcomes should not supplant those recommendations of specific mandate holders which were either not included in recommendations accepted by the State, or not considered by the Working Group or the plenary. It was stressed that UPR follow-up by mandate holders should not infringe upon their independence. C. Lessons learned and recent developments in relation to common approaches to human rights situations: follow-up to the fifteenth annual meeting and developments in 2008/09 31. Mandate holders had a discussion of their working methods, in particular common approaches to human rights situations, following up on a discussion started at the fifteenth annual meeting. 32. Participants noted the responsibility of all special procedures, as mandated by the Council, to take effective measures to enhance the promotion and protection of human rights, and discussed providing guidance to the Coordination Committee in developing a more systematic approach to situations where collective responses by special procedures could be justified and desirable while not pre-empting ongoing joint action by some mandate holders. The Committee was requested to keep in mind that such situations should be particularly serious ones involving gross and systematic violations of human rights, including war crimes, crimes against humanity, genocide, or the risk of those violations; or situations in which other serious violations of human rights were being committed or threatened and which cut across a wide range of rights as provided in the Universal Declaration of Human Rights; or in cases where the ability of mandate holders to pursue their work was being obstructed, or their independence jeopardized. D. Planning and resources 33. Participants were briefed on interpretation by officials from the Interpretation Service of the Conference Services Division of the United Nations Office at Geneva. It was noted that while the workload had been steadily growing and country missions represented a challenge, considerable progress had been achieved. Close and constructive cooperation with the Secretariat was welcomed. The use of the Guidelines Regarding Interpretation Services during Missions with Human Rights Mechanisms was encouraged. For cooperation to be successful, attention must be paid to the mission’s preparatory stage and to time management. Overly long working hours could compromise the quality of the interpretation, in particular in politically and security-sensitive missions. 34. Mandate holders commended the quality and professional services provided by the interpreters, noting their crucial support. Participants also noted that different missions had different requirements and arrangements should therefore be flexible. Good practices were shared during the dialogue, such as the use of portable equipment.
