A/HRC/27/45 Chair-Rapporteur called on the Secretariat to explain the applicable rules. It was consequently clarified that unless otherwise laid down in the resolutions establishing subsidiary bodies of the Human Rights Council, such as the Social Forum, participation in them was limited to NGOs in consultative status with the Economic and Social Council. However, the Working Group could consider and agree to expanding the participation of NGOs to include those not in consultative status with the Economic and Social Council, in which case it should make a recommendation to that effect for endorsement by the Human Rights Council. IV. Conclusions and recommendations 82. At the final meeting of its fifteenth session, on 16 May 2014, the Working Group on the Right to Development adopted, by consensus, its conclusions and recommendations, in accordance with its mandate established by Commission on Human Rights resolution 1998/72.
