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: Ukraine
Date of decision:

The applicant's Ukrainian nationality was withdrawn rendering him stateless, and subsequently a travel ban of 3 years was imposed on him due to a procedural violation of the border crossing rules. The applicant argued that the travel ban is disproportionate, that he enjoys lawful residence in Ukraine, has very close ties with Ukraine, and that the ban interferes with his right to challenge the deprivation of nationality which rendered him stateless in person in court. 

Court name: Constitutional Court of Austria (Verfassungsgerichtshof)
State: Austria
Date of decision:

The applicant acquired Austrian nationality in 1995 and renounced her former Turkish nationality in 1996 as a condition for retaining the Austrian nationality. In 2018 the Austrian authorities declared that she has no longer been an Austrian national since 1997 as it appeared that she voluntarily re-acquired her Turkish nationality at that time, which is a ground for automatic loss of Austrian nationality. The Court set aside the determination of loss of Austrian nationality as it did not carry out a proportionality test on the basis of the Tjebbes judgment.

Court name: Court of North-Holland
Date of decision:

The applicant naturalised in the Netherlands, after having derived his legal residence from being a partner of a Dutch resident. His naturalisation was later withdrawn, as it appeared he has concluded a marriage and fathered a child with another person in Egypt while still deriving residence rights from his relationship in the Netherlands. The Court confirmed the legality of withdrawal, despite the applicant becoming stateless as a result.
