The case concerns the refusal by the Head of the Civil Registry Office of Kraków (Poland) to transcribe into the Polish register of civil status the birth certificate of the daughter of K.S. and her wife S.V.D., issued by Spanish authorities. This lack of registration hindered the issuance of a passport, which impacted the child’s freedom of movement.
The Court interpreted Articles 20 and 21 of the TFEU, to mean that the Member State of which a child of a same-sex couple is a national (i) is obliged to issue to that child an identity card or a passport without requiring the prior transcription of a birth certificate of that child into the national register of civil status, and (ii) is obliged to recognise the document from another Member State that permits the child to exercise, without impediment, the right to move and reside freely within the territory of the Member States.
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 in the US, and his birth certificate indicated a Polish national as the father, and an unknown surrogate mother as the mother. Polish authorities refused to confirm the applicant acquired Polish nationality at birth as a child of a Polish parent, because the birth certificate is against the Polish public order, in particular the prohibition of surrogacy. The courts ruled in favour of the applicant, stating that confirmation of his Polish nationality on the basis of the birth certificate does not amount to validation of surrogacy.
The applicants are children born presumably in a surrogacy arrangement in Ukraine to two Austrian nationals. Even though the custody of the commissioning parents over the applicants was confirmed under the Austrian law, their parentage and consequently the Austrian nationality of the applicants was initially denied. The Court considered that the best interests of the child prevail in such a case over the prohibition of surrogacy under Austrian law, and confirmed the applicants' right to Austrian nationality.
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 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.
The cases concerned the refusal to grant legal recognition in France to parent-child relationships that had been legally established in the United States between children born as a result of surrogacy treatment and the couples who had had the treatment. Totally prohibiting the establishment of a relationship between a father and his biological children born following surrogacy arrangements abroad was found in breach of the Convention
