The judgment is an answer to a general legal question as to whether Polish law allows the incorporation of foreign birth certificates where parents are of the same sex. The question was prompted by the authorities' refusal to transcribe into Polish law the foreign birth certificate of a child born to two mothers, both of whom are Polish nationals. The applicant argued that since lack of a transcribed birth certificate inhibits her child's access to a Polish passport, it in practice leads to a situation that is identical to statelessness.
The applicant was born abroad to two Polish mothers, and acquired Polish nationality on the basis of at least one of his parents being Polish. However, he was unable to access Polish identity documents, for which a transcription of a foreign birth certificate into the Polish legal order is required - the latter being denied as the concept of two mothers contradicts the fundamental principles of Polish legal order. The Court ruled in favour of the applicant, relying heavily on national and international children's rights norms.
The public prosecutor appealed to the Provincial Administrative Court in Kraków (“Court”) against the transcription of A.Z.’s birth certificate by the Head of the Registry Office in Krakow into the Polish Civil Register, claiming that it is contrary to the fundamental principles of the legal order of the Republic of Poland because A.Z.’s birth certificate listed two women as parents. The appeal was dismissed.
The Court stated that due to the large number of states that have ratified the Convention on the Rights of the Child and because many states include similar provisions in their national legislation, legal experts argue that the right of a child to nationality is part of international customary law, therefore everyone should acquire a nationality at birth.
