(b) where the nationality has been obtained by misrepresentation or fraud. 3. Notwithstanding the provisions of paragraph 1 of this Article, a Contracting State may retain the right to deprive a person of his nationality, if at the time of signature, ratification or accession it specifies its retention of such right on one or more of the following grounds, being grounds existing in its national law at that time: (a) that, inconsistently with his duty of loyalty to the Contracting State, the person (i) has, in disregard of an express prohibition by the Contracting State rendered or continued to render services to, or received or continued to receive emoluments from, another State, or (ii) has conducted himself in a manner seriously prejudicial to the vital interests of the State; (b) that the person has taken an oath, or made a formal declaration, of allegiance to another State, or given definite evidence of his determination to repudiate his allegiance to the Contracting State. 4. A Contracting State shall not exercise a power of deprivation permitted by paragraphs 2 or 3 of this Article except in accordance with law, which shall provide for the person concerned the right to a fair hearing by a court or other independent body. Article 9 A Contracting State may not deprive any person or group of persons of their nationality on racial, ethnic, religious or political grounds. Article 10 ANNEXES 1. Every treaty between Contracting States providing for the transfer of territory shall include provisions designed to secure that no person shall become stateless as a result of the transfer. A Contracting State shall use its best endeavours to secure that any such treaty made by it with a State which is not a party to this Convention includes such provisions. 2. In the absence of such provisions a Contracting State to which territory is transferred or which otherwise acquires territory shall confer its nationality on such persons as would otherwise become stateless as a result of the transfer or acquisition. Article 11 The Contracting States shall promote the establishment within the framework of the United Nations, as soon as may be after the deposit of the sixth instrument of ratification or accession, of a body to which a person claiming the benefit of this Convention may apply for the examination of his claim and for assistance in presenting it to the appropriate authority. 81
