United Nations special rapporteur

Special rapporteur (or independent expert) is the title that the United Nations (UN) gives to independent human rights experts called to report or advise on human rights from a thematic or country-specific perspective. Depending on the specific mandate, there can also be working groups composed of an independent expert from each of the five UN regional groupings: Africa, Asia, Latin America and the Caribbean, Eastern Europe, and the Western group.
