The Special Procedures of the Human Rights Council are independent human rights experts with mandates to report and advise on human rights from a thematic or country-specific perspective. The system of Special Procedures is a central element of the United Nations human rights machinery and covers all human rights: civil, cultural, economic, political, and social. In the context of the 2011 review of its work and functioning, the Human Rights Council reaffirmed the obligation of States to cooperate with the Special Procedures, and the integrity and independence of Special Procedures. It also reaffirmed the principles of cooperation, transparency and accountability and the role of the system of Special Procedures in enhancing the capacity of the Human Rights Council to address human rights situations. Member States confirmed their strong opposition to reprisals against persons cooperating with the United Nations and its human rights mechanism and representatives.
