It has been acknowledged that the institution of UN special rapporteurs for human rights known as the special procedures have played an important role over a long period of time in promoting and protecting human rights in some of the most difficult circumstances and on some of the most challenging issues. They have done so through not only monitoring and fact finding but also standard-setting over the past three or so decades. They have been credited for influencing significantly the elaboration, interpretation and implementation of international human law and brought the human rights work of the UN to the ordinary men and women around the globe. However, the institution of special rapporteurs itself seems to be coming under pressure not only from outside but also from inside the UN system. Currently, there is a debate taking place on the role of the special rapporteurs in the context of the review process of the Human Rights Council itself by the UN General Assembly since most of the special rapporteurs are appointed by the council to assist it in achieving the objectives set out in the General Assembly resolution of 2006 that created the council to replace the former Commission on Human Rights. Given the nature of the debate that has taken place within the council in the recent past, there are fears that some states or groupings of states may try to abolish the country special rapporteurs and undermine the significance of certain special rapporteurs especially those holding mandates relating to certain core civil and political rights by imposing additional restrictions on their freedom of action.The importance of the special rapporteur system appears evident, yet there is no consensus on good or best practice in the way that mandates should be carried out or the extent or limits of the responsibilities of governments to assist special rapporteurs. Moreover, there is limited systematic scholarly examination of the nature and impact of the role of the special rapporteur in international law. It is then timely to examine the role of the special rapporteurs in the development and promotion of international human rights norms and this is what the articles included in this special issue seek to do. It is in this context that the Centre for International Governance at the School of Law of the University of Leeds decided to organise an international research workshop designed to examine closely the role of special rapporteurs in the development and promotion of international human rights norms. The idea was to understand the role and challenges that the special rapporteurs
