11 party; (d) voluntary pledges and commitments made by States; and (e) applicable international humanitarian law. The universal periodic review of any given country bases itself on three documents: the State report; a compilation of United Nations information; and a compilation of information from other relevant stakeholders, such as NGOs and NHRIs. Information contained in the reports of the treaty bodies on existing issues and recommendations of relevance to specific countries comprises a significant part of the compilation of United Nations information, thus ensuring that the work of the treaty bodies and the universal periodic review are complementary. Relationship between the treaty bodies and the special procedure mandate holders Information sharing between the treaty bodies and the special procedures is a reciprocal and mutually beneficial process. Information from the special procedures is systematically made available to the treaty bodies for their examination of State party reports. In addition, specific treaty bodies have close relations with special procedures sharing common themes. For example, the Committee against Torture shares the country information it receives with the Special Rapporteur on torture and other cruel, inhuman or degrading treatment or punishment, and both meet formally once a year. The Committee on Economic, Social and Cultural Rights has close relations with the Special Rapporteurs on the right to housing and on the right to education. The special procedure mandate holders and the treaty bodies also interact when the former attend sessions of the latter, for instance during thematic debates. II. NOMINATIONS AND ELECTIONS A. General States parties to human rights treaties generally elect treaty body members at meetings of States parties. These meetings are usually held every two years at United Nations Headquarters in New York, although the elections under the Convention against Torture and its Optional Protocol take place at the United Nations Office at Geneva. The elections of the Committee on the Rights of Persons with Disabilities take place during a Conference of States parties, a meeting attended by States, civil society organizations (CSOs) and other stakeholders during which various aspects of the implementation of the Convention are also discussed. For the Committee on Economic, Social and Cultural Rights, elections take place at a meeting of the United Nations Economic and Social Council.
