A/66/227 violence against children, of which the ratification of the Protocol is a core component. 15. Since the launching of the campaign, eight States have ratified the Protocol: Djibouti, Guinea-Bissau, Guyana, Malta, Mauritius, Nigeria, Pakistan and Saudi Arabia. The Central African Republic has signed the instrument. 16. In May 2011, in order to accelerate progress, the Special Representative, in collaboration with strategic partners, hosted a treaty event in New York on the occasion of the first anniversary of the launching of the campaign, and supported a regional event in Addis Ababa hosted by the African Union with the Economic Commission for Africa, UNICEF and OHCHR. At these and other high-level meetings, the campaign received strong support from Governments, United Nations agencies, parliamentarians, children’s advocates, faith-based organizations and civil society organizations. 17. At least 18 States have made formal commitments to the ratification of the Protocol, including within the framework of the universal periodic review of the Human Rights Council and before the Committee on the Rights of the Child or human rights mandate-holders. Of those that are not yet parties, 40 per cent have ratified the Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, supplementing the United Nations Convention against Transnational Organized Crime, and 90 per cent have ratified ILO Convention No. 182, on the Worst Forms of Child Labour; these address similar areas of concern. B. Consolidating the legal protection of children from all forms of violence 18. The adoption of legislation to prohibit all forms of violence against children, in all settings, together with an appropriate legal framework for preventing and responding to violence, was a critical recommendation of the study and constitutes a priority of the Special Representative’s mandate. To advance progress in this crucial area, the Special Representative organized, together with OHCHR, the InterParliamentary Union and the international non-governmental organization Advisory Council for the follow-up to the study on violence against children, an expert consultation on law reform held in Geneva in July 2011. The main findings of the consultation are presented below. 19. As highlighted in previous reports, law reform on violence against children is an area that is gaining momentum. When the study was finalized, 16 countries had legislation prohibiting violence in all settings. To date, 29 have introduced such a comprehensive legal ban, in some cases incorporating it into their Constitutions. In some countries, courts have also been instrumental in guaranteeing the right of the child to respect for his or her physical integrity and to freedom from violence, including within the family. Across regions, there are significant initiatives under way to achieve the full legal prohibition of violence against children, and many countries have adopted legislation on specific forms of such violence, including sexual abuse and exploitation, trafficking and harmful traditional practices. 20. Over the past two years, regional organizations and political groupings have also embraced this goal as a priority, including the Organization of Islamic 6 11-44118
