Nabycia polskiego obywatelstwa a urodzenie przez matkę zastępczą : uwagi na tle wyroków Naczelnego Sądu Administracyjnego z dnia 6 maja 2015 r.: II OSK 2372/13 oraz II OSK 2419/13

The article is a comment on the Supreme Administrative Court's verdicts of 6 May 2015 (signatures: II OSK 2372/12 and II OSK 2419/13) by which confirmation of the acquisition of Polish nationality based on ius sanguinus principle was denied to a child as the legal parentage was established in the foreign judgement and birth certificate indicating the genetic father and his same sex partner as parents. The denial was justified by the public policy clause. The Court underlined that the principle of marriage as a union between one woman and one man and the rule that mother is a woman that gave birth to the child are of fundamental character. The aim of the article is the analysis of various public and private international law institutions that interconnect in the discussed verdict: rules on acquisition of citizenship, ius sanguinus principle confronted with same sex parentage, the notion of "parent" in the citizenship law, the principle of ex legerecognition of foreign judgements, public policy clause as an obstacle to that recognition and also right to respect for private life as defined in the jurisprudence of European Human Rights Court.
