mother or father. Moreover, the Convention on the Elimination of All Forms of Discrimination Against Women prohibits sex-based discrimination in the conferral of nationality. An important measure to prevent statelessness at birth bestows nationality to children born in a territory who would otherwise be stateless. This norm is stipulated in the 1961 Convention on the Reduction of Statelessness; appears in several regional human rights treaties, including the American Convention on Human Rights, the European Convention on Nationality, and the African Charter on the Rights and Welfare of the Child; and is implicit in the United Nations Convention on the Rights of the Child. Discrimination In most large-scale statelessness situations, statelessness is a result of discrimination. Many states define their body of citizens based on ethnicity, leading to the exclusion of large groups. This violates international laws against discrimination. The United Nations Committee on the Elimination of Racial Discrimination stated on October 1, 2014, that the "deprivation of citizenship on the basis of race, colour, descent, or national or ethnic origin is a breach of States' obligations to ensure non-discriminatory enjoyment of the right to nationality". State succession In some cases, statelessness is a consequence of state succession. Some people become stateless when their state of nationality ceases to exist, or when the territory on which they live comes under the control of another state. This was the case after the Soviet Union had disintegrated in 1991, and also in the cases of Yugoslavia , East Pakistan and Ethiopia. According to the United Nations Office of Legal Affairs, the Council of Europe Convention on the Avoidance of Statelessness in Relation to State Succession is the only treaty that aims to reduce this problem. Seven states have joined it. Administrative obstacles People may also become stateless as a result of administrative and practical problems, especially when they are from a group whose nationality is questioned. Individuals might be entitled to citizenship but unable to undertake the necessary procedural steps. They may be required to pay excessive fees for documentation proving nationality, to provide documentation that is not available to them, or to meet unrealistic deadlines; or they may face geographic or literacy barriers. In disruptive conflict or post-conflict situations, many people find that difficulties in completing simple administrative procedures are exacerbated. Such obstacles may affect the ability of individuals to complete procedures such as birth registration, fundamental to the prevention of statelessness
