A/HRC/33/33 84. Given the role that national human rights institutions can play at the national level in follow-up to the universal periodic review and in developing tools to monitor and assess progress in the implementation of recommendations, OHCHR continued to actively support and encourage their participation in the review process. B. Treaty bodies 85. OHCHR continued to support the participation of national human rights institutions in treaty bodies sessions. The secretariats of the treaty bodies, the National Institutions, Regional Mechanisms and Civil Society Section and the Geneva representative of the Global Alliance of National Human Rights Institutions liaised with national human rights institutions prior to each session to encourage them to provide written or oral information, and to attend the sessions. OHCHR also prepared briefings on institutions for the attention of treaty bodies and disseminated relevant recommendations and concluding observations to the institutions concerned. 86. During the reporting period, human rights treaty bodies reviewed 319 States parties, 236 of which had national human rights institutions. Of those 236 institutions, more than 200 interacted with treaty bodies by submitting reports, providing briefings before the review or attending the sessions (see annex III). 87. Treaty bodies have provided national human rights institutions with information notes, statements and advice and tools to facilitate their effective engagement and invited representatives of those institutions to their meetings. 88. In September 2014, the Committee on Enforced Disappearances adopted a paper on its relationship with national human rights institutions to enhance the opportunities for those institutions to engage with the Committee and contribute to its work. The Committee has engaged with the Global Alliance of National Human Rights Institutions in that process. 89. In September 2014, the Committee on the Rights of Persons with Disabilities held its first meeting with national human rights institutions and independent monitoring frameworks to discuss ways in which monitoring of the Convention at the national and international levels could be mutually reinforced. The Committee subsequently adopted draft guidelines on the establishment of independent monitoring frameworks and their participation in the work of the Committee, during its fifteenth session (29 March-21 April 2016). IV. Recommendations A. Recommendations to Member States 90. Member States are encouraged to establish national human rights institutions compliant with the Paris Principles or to strengthen the structures and independence of existing institutions in order to enable the effective fulfilment of their mandate, taking into account the recommendations of the Sub-Committee on Accreditation of the Global Alliance of National Human Rights Institutions and the advice of OHCHR. 91. Member States are encouraged to ensure that national human rights institutions are provided with a broad mandate to protect and promote all human rights, including economic, social and cultural rights, and are granted adequate powers of investigation into allegations of human rights violations, including authorization to visit places of deprivation of liberty.
