A/HRC/34/34 prosecute and try individuals reasonably believed to have committed crimes against humanity (see A/HRC/32/47, para. 133). J. Follow-up activities 38. Mandate holders continued to prioritize follow-up to their previous actions by, inter alia, issuing follow-up communications to cases previously transmitted to States and nonState actors, and observations on communications reports, issuing follow-up press releases, undertaking follow-up visits, sending questionnaires and presenting reports to follow up on the implementation of recommendations made after country visits, and convening expert meetings and consultations (see A/HRC/34/34/Add.1, chap. IX). 39. A positive example in this regard was provided by the Working Group on Arbitrary Detention, which, at its seventy-fifth session, held from 18 to 27 April 2016, elected a ViceChair on follow-up on all actions taken by the Working Group. At the same session, the Working Group also decided to introduce a systematic follow-up procedure in the context of its opinions. 40. Another positive example is the Special Rapporteur on human rights and extreme poverty, who, after submitting a report on the responsibility of the United Nations for the cholera outbreak in Haiti (A/71/367), followed up on this issue by sending an open letter to the Deputy Secretary-General on 5 October 2016,6 which contributed to the presentation by the Secretary-General of a new approach taken by the Organization to this issue. 41. The Coordination Committee used the opportunity of its meetings with various representatives of the United Nations and States to stress the importance of follow-up. It also held a webinar in cooperation with the Development Operations Coordination Office on the theme “Strengthening the integration of human rights in the work of the United Nations: a discussion on the opportunities and challenges in implementing and following up on human rights recommendations”, with the participation of representatives of United Nations country teams in Brazil and Argentina and more than 50 other United Nations participants from all regions. III. Coordination Committee of Special Procedures 42. In 2016, the Coordination Committee of Special Procedures continued to facilitate coordination among mandate holders and interaction with a range of stakeholders. It pursued efforts to consolidate its role, to enhance its capacities to respond to requests from mandate holders and other stakeholders, and to act as the main body representing and acting on behalf of special procedures, including by strengthening the visibility of the system of special procedures and organizing face-to-face meetings three times a year. 43. As an important part of its work, the Committee held consultations with a wide range of stakeholders, including the Office of the Secretary-General, the United Nations High Commissioner for Human Rights, the Chair of the Third Committee of the General Assembly, the President of the Human Rights Council, various senior representatives of the Department of Peacekeeping Operations, the Department of Political Affairs, the Peacebuilding Support Unit, UNDP and the Development Operations Coordination Office, the 6 8 Available at www.ohchr.org/Documents/Issues/EPoverty/20161005_SR_poverty_letter_to_DSG.pdf; see alsowww.ohchr.org/Documents/Issues/EPoverty/20161012_SR_Alston_letter_from_DSG.pdf.
