A/HRC/16/32 6. Six meetings of States parties took place in Geneva or New York during 2010, essentially to hold elections to fill seats for which the previous members’ mandates had ended (the Subcommittee on Prevention of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment, the Committee on the Elimination of Discrimination against Women, the Committee on Economic Social and Cultural Rights, the Committee on the Rights of Persons with Disabilities, the Committee on the Elimination of Racial Discrimination and the Committee on the Rights of the Child). In the case of the Subcommittee on Prevention of Torture the membership expanded to 25 members following the entry into force of the Convention for the fiftieth State party and its meeting of States parties thus also elected experts to fill the new seats. The membership of the Committee on the Rights of Persons with Disabilities was enlarged from 12 to 18 following the entry into force of the Convention for the sixtieth State party. During 2010, human rights treaty bodies also had three informal meetings with States parties which were widely attended and provided an opportunity for States parties and treaty bodies to discuss the most recent developments in the work of treaty bodies, as well as other matters of common interest, in particular the efforts of treaty bodies to improve their working methods (the Committee on Economic, Social and Cultural Rights, the Committee on the Elimination of Discrimination against Women, and the Committee against Torture). An open-ended working group of the Human Rights Council on an optional protocol to the Convention on the Rights of the Child to provide a communications procedure met from 6 to 10 December 2010. 7. OHCHR updated the training tool (DVD) on the work of the treaty bodies, entitled “Bringing human rights home”, which is available in all United Nations official languages. In addition to traditional treaty body support provided by country offices, the Human Rights Treaties Division of OHCHR has continued to support in 2010 a number of capacity-building activities and training sessions upon requests of State parties, United Nations partners and regional organizations, on the common core document and treatyspecific guidelines, reporting, individual communications and follow-up to recommendations in Bahrain; Belarus; Cap Verde; Hong Kong, China; Japan; Kazakhstan; the former Yugoslav Republic of Macedonia; Mexico; Peru; Qatar; Senegal; and Turkmenistan. Also, the Division’s staff trained or presented the work of the treaty bodies at specific events upon the request of regional organizations such as the Council of Europe, United Nations departments, programmes and specialized agencies, academia and civil society. 8. On 29 November 2010, OHCHR organized an event to celebrate the twentieth anniversary of the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families, in cooperation with the International Steering Committee for the campaign for ratification of the Convention. Participants discussed legal, social and practical improvements in the protection of migrants and migration policies following ratification; the relationship between international migration, development and the protection of human and labour rights of migrants; the application and applicability of the standards contained in the Convention, and the current and future prospects for further ratifications. 9. OHCHR organized a one-day celebration on 29 October 2010 to commemorate the 100th session of the Human Rights Committee. On this occasion, States parties, United Nations bodies and other intergovernmental organizations, national human rights institutions, international and national non-governmental organizations and academics were invited to join the members of the Committee for discussions on the main following themes: identifying and stocktaking the main achievements, constraints and challenges faced by the Committee; assessing the implementation of the Covenant in the various regions of the world, with examples of achievements and best practices regarding civil and political rights; and identifying priorities for future activities of the Committee. 3
