The Report of the Working Group (WG) is a factual summary of the three hour review. It is produced by the troika with the help of the Human Rights Council Secretariat and with the full involvement of the State under Review and adopted "ad referendum" during the WG session usually 48h after the end of the review of the State.
States can bring editorial changes to their own statement during two weeks after the adoption by writing to the Secretariat (uprstates [at] ohchr.org).
