The applicant, who described himself as being Saharawi, claimed that he should not be granted statelessness status because he was entitled to Spanish nationality. Alternatively, he argued that he should be recognised as being stateless. The Supreme Court found that his entitlement to Spanish nationality could not be considered, given that it has never been requested before by the applicant. However, the court found that given that he could not be considered as Moroccan or Algerian under the law of these two countries, nor as covered by the exception foreseen in Article 1(2)(i) of the 1954 Convention, his statelessness status should be recognised.
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.
