Article 7

4 A naturalized person may lose his nationality on account of residence abroad for a period, not less than seven consecutive years, specified by the law of the Contracting State concerned if he fails to declare to the appropriate authority his intention to retain his nationality.

5 In the case of a national of a Contracting State, born outside its territory, the law of that State may make the retention of its nationality after the expiry of one year from his attaining his majority conditional upon residence at that time in the territory of the State or registration with the appropriate authority.

6 Except in the circumstances mentioned in this Article, a person shall not lose the nationality of a Contracting State, if such loss would render him stateless, notwithstanding that such loss is not expressly prohibited by any other provision of this Convention.

Для особо хорошо образованных notwithstanding означает "не смотря на". Fraud относится к 8 статье.
