A/HRC/28/74 means to hold States to account would seem to be the use of the universal periodic review mechanism and for the relevant treaty-based bodies to require Member States to address the issue in their periodic reports so as to raise public awareness to pressure States to prevent or, at least, to mitigate the impact of such measures on the enjoyment of human rights. There may also be a need for the Human Rights Council to consider developing specific rules, procedures and guidelines to ensure transparency and more accountability if and when States employ unilateral coercive measures that are likely to have a negative impact on the enjoyment of human rights in targeted or non-targeted States. 64. In this regard, the Human Rights Council, at its twenty-seventh session, in fact adopted resolution 27/21, in which it created, for a period of three years, a new mandate of Special Rapporteur on the negative impact of unilateral coercive measures on the enjoyment of human rights, thus corroborating the findings of the present study. The Special Rapporteur has a mandate: (a) To gather all information, wherever it may occur, including from Governments, non-government organizations and any other parties, relating to the negative impact of unilateral coercive measures on the enjoyment of human rights; (b) To study trends, development and challenges in relation to the negative impact of unilateral coercive measures on the enjoyment of human rights and to make guidelines and recommendations on ways and means to prevent, minimize and redress the adverse impact of unilateral coercive measures on human rights; (c) To make an overall review of independent mechanisms to assess unilateral coercive measures to promote accountability; (d) To contribute to strengthening the capacity of OHCHR to provide affected countries with technical assistance and advisory services to prevent, minimize and redress the adverse impact of unilateral coercive measures on human rights. 65. In discharging the mandate, the Council also requested the Special Rapporteur (a) to draw the attention of the Human Rights Council and the High Commissioner to situations and cases regarding the negative impact of unilateral coercive measures on the full enjoyment of human rights; and (b) to cooperate with other relevant United Nations bodies, including the High Commissioner, human rights treaty bodies, the special procedures and mechanisms, specialized agencies, fund and programmes, regional intergovernmental organizations and their mechanisms, with the aim to prevent, minimize and redress the adverse impact of unilateral coercive measures on human rights. 18
