IV. International legal framework and OSCE commitments thereby supplementing UNHCR’s supervisory responsibilities. Some human rights norms form part of customary international law and therefore apply to all States, irrespective of a State’s treaty obligations. In particular, the prohibition of discrimination is a key customary norm that applies both to the acquisition/ loss of nationality and the treatment of stateless persons. An overview of the relevant international legal framework applicable to the right to nationality, in particular the prohibition of arbitrary deprivation of nationality, is provided in the 2009 UN report Human rights and arbitrary deprivation of nationality: report of the SecretaryGeneral. 39 Moreover, the UN Human Rights Council has adopted several resolutions related to statelessness. Two such resolutions were adopted during the 32nd regular session of the Council in June and July 2016: The resolution “The right to a nationality: women’s equal nationality rights in law and in practice” urges States to eliminate gender discriminatory nationality laws and practices – a major cause of statelessness globally. It also calls on the UN Office of the High Commissioner on Human Rights (OHCHR) and UNHCR to organize an inter-sessional workshop to showcase good practices in promoting women’s equal nationality rights in law and in practice. The resolution was adopted by consensus and had more than 100 State cosponsors.40 The second resolution “Human rights and arbitrary deprivation of nationality” calls on States to refrain from enacting or maintaining legislation that would arbitrarily deprive persons of their nationality on grounds of race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status, including disability.41 Other regional instruments that recognize the right to a nationality The 1954 and 1961 Statelessness Conventions and international human rig hts treaties are complemented by the standards contained in regional treaties. Such treaties in the Americas, in Europe, in the Commonwealth of Independent States, and in Islamic countries recognize the right to a nationality. They further establish additional obligations for States Parties 33
