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 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.
