of its resolution 2003/21 of 13 August 2003, and also of the final report of the Special Rapporteur of the Sub-Commission on the rights of non-citizens (E/CN.4/Sub.2/2003/23 and Add.1-4), Expressing its deep concern at the arbitrary deprivation of persons or groups of persons of their nationality, especially on racial, national, ethnic, religious, gender or political grounds, Recalling that arbitrarily depriving a person of his or her nationality may lead to statelessness, and in this regard expressing concern at various forms of discrimination against stateless persons that violate the obligations of States under international human rights law, Emphasizing that the human rights and fundamental freedoms of persons whose nationality may be affected by State succession must be fully respected, 1. Reaffirms that the right to a nationality of every human person is a fundamental human right; 2. Recognizes that arbitrary deprivation of nationality on racial, national, ethnic, religious, political or gender grounds is a violation of human rights and fundamental freedoms; 3. Calls upon all States to refrain from taking discriminatory measures and from enacting or maintaining legislation that would arbitrarily deprive persons of their nationality on grounds of race, colour, gender, religion, political opinion or national or ethnic origin, especially if such measures and legislation render a person stateless; 4. Urges all States to adopt and implement nationality legislation with a view to avoiding statelessness, consistent with fundamental principles of international law, in particular by preventing arbitrary deprivation of nationality and statelessness as a result of State succession; 5. Calls upon States that have not already done so to consider accession to the Convention on the Reduction of Statelessness and the Convention relating to the Status of Stateless Persons;
