Suitability to the conditions of assignment/ability to work in difficult contexts Field visits, especially in hardship zones, may require special attention to physical health conditions. (c) Gender balance The selection of members must seek to ensure equitable representation of women and men. Commissions/missions that investigate serious violations of women’s human rights and sexual violence against women and girls will require expertise that may best be represented through female members. (d) Geographic diversity The international character of the body is best reflected by geographically diverse membership. Ensuring adequate representation of persons from the region of the country that is the subject of the inquiry often facilitates an understanding among the members of the political, legal, social and cultural context in which the investigation is to be conducted.
