A/80/186 Human Rights Council. 21 While the Special Rapporteur agrees that a treaty on the rights of minorities is much needed, he wishes to express his doubts about the method of drafting proposed by the previous mandate holder. 22 It would be more appropriate to ask the International Law Commission to study the feasibility of a “minority treaty” on the basis of a thorough and detailed review of existing international norms that protect minorities. B. Research methodology 35. The Special Rapporteur used a three-phase approach in order to analyse the work done on minority issues by United Nations entities, funds, programmes, specialized agencies and related organizations. First, he compiled the work that had been done by the previous mandate holders with regard to implementation by the United Nations system of the Declaration on the Rights of Persons belonging to National or Ethnic, Religious or Linguistic Minorities. The Special Rapporteur noted that not much work had been done on the contribution of specialized agencies or related organizations. Accordingly, information is provided in the present report on the contributions of specialized agencies and related organizations, most notably the Food and Agriculture Organization of the United Nations (FAO), International Fund for Agricultural Development (IFAD), International Labour Organization (ILO), International Organization for Migration (IOM), International Telecommunication Union (ITU), Office of the United Nations High Commissioner for Refugees (UNHCR), United Nations Educational, Scientific and Cultural Organization (UNESCO), United Nations Entity for Gender Equality and the Empowerment of Women (UN-Women), United Nations Industrial Development Organization (UNIDO), United Nations Office for Project Services (UNOPS), World Bank Group, World Health Organization (WHO), World Intellectual Property Organization (WIPO) and World Meteorological Organization. 36. The Special Rapporteur also analysed the work done by the following Departments and Offices of the Secretariat: Department of Social and Economic Affairs, Department of Global Communications, Department of Peace Operations, Department of Political and Peacebuilding Affairs, Office for the Coordination of Humanitarian Affairs; Office of the United Nations High Commissioner for Human Rights (OHCHR), Office of the High Representative for the Least Developed Countries, Landlocked Developing Countries and Small Island Developing States and the United Nations Office for Disaster Risk Reduction. 37. In addition, he reviewed the work done by the principal organs of the United Nations, including the Economic and Social Council, General Assembly and Security Council, some subsidiary bodies, such as the Human Rights Commission and the Peacebuilding Commission, and other entities, programmes and funds, such as the United Nations Children’s Fund (UNICEF), United Nations Conference on Trade and Development (UNCTAD), United Nations Development Programme (UNDP), United Nations Environment Programme (UNEP), United Nations Human Settlements Programme (UN-Habitat), United Nations Population Fund (UNFPA) and World Food Programme (WFP). 38. The Special Rapporteur, as part of the second phase of his research efforts, reached out directly to United Nations entities in order to develop a comprehensive overview of the work done by the United Nations system towards the realization of the Declaration. He received information from 33 United Nations entities, __________________ 21 22 25-11708 See A/HRC/52/27, para. 66; and www.ohchr.org/sites/default/files/2023-01/Annex1.-A-HRC-5227_0.docx.
