In this open letter, WILPF conveys its deep concern regarding the critical funding situation affecting the UN’s human rights mechanisms and the Office of the High Commissioner for Human Rights (OHCHR). WILPF understands that the combination of delays in payments of UN member states’ assessed contributions to the regular budget and the 25% cut to travel of UN representatives, including treaty body experts and Special Procedure mandate holders, and other budget cuts (2018-2019) may adversely impact on the capacity of various human rights mechanisms to carry out their mandates effectively.
