Court name: Court of Justice of the European Union
Date of decision:

The authorities refused to examine the applications of Dutch nationals, with dual nationality of a non-EU country, for renewal of their Dutch passports. The decision was based on the fact that they had lost their Dutch nationality because they possessed a foreign nationality and had their principal residence for an uninterrupted period of 10 years outside the Netherlands and the EU. The CJEU found that Member States may lay down rules regulating the loss of their nationality and, as a result, the loss of EU citizenship, where the genuine link between the person and that State is durably interrupted. Nevertheless, the loss of nationality must respect the principle of proportionality, which requires an individual assessment of the consequences of that loss for the person from the point of view of EU law.

Court name: Supreme Administrative Court
State: Poland
Date of decision:

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.
