The applicant was born in Poland to a Vietnamese mother. When she was 9 years old a Polish citizen formally recognised her as his daughter, and the local authority subsequently confirmed that she is a Polish citizen by birth. She was growing up as a Polish citizen until another 8 years later the central government authorities invalidated the confirmation of nationality by the local authority, as according to the Polish Citizenship Law changes in parenthood can only lead to acquisition of Polish citizenship if they take place within 1 year of birth. The applicant's arguments related to article 8 ECHR, best interests of the child, as well as long-term presumption of Polish citizenship due to no fault of the applicant, although the court dismissed all arguments.
Germany’s highest administrative court decides on a case in which stateless minors (the applicants) were granted German nationality. The applicants’ parents applied for their nationality using false information, namely that the family would originate from Lebanon instead of Turkey. The Court held that the withdrawal of nationality is only valid if done promptly, i.e. within a maximum of five years after the nationality has been granted.
The recognition of stateless status cannot be denied on the basis that the applicant has not undertaken the necessary steps in order to regain the lost nationality, even if it was voluntarily renounced.
