At its session concluded earlier this month, the UN Human Rights Council established two new country rapporteurships, one on Afghanistan, and one on Burundi. The call for applicants has now been posted. However, even before any applications have been collected and reviewed, the Office of the High Commissioner for Human Rights seems to have already decided that both appointees will be men, based on the Name of Mandate-holder column (click screen shot below to enlarge). They’ve done this for the two thematic mandate openings, as well.
UPDATE on 29 October 2021: I see that today the OHCHR has now fixed this issue on the country rapporteur page by removing the “Mr.” from the two open positions in the Mandate-holder column, and on the thematic rapporteur page it has removed the “Mr.” from this column for the newly-created thematic rapporteurship on climate change, but has still left in place the “Mr.” in the opening on the Working Group of Experts on People of African Descent.
FURTHER UPDATE, 5 November 2021: The OHCHR has now removed the remaining “Mr.” from the vacancy listing in the Mandate-holder column on the thematic procedures webpage.
