The Court held that it is not contrary to EU law for Member States to withdraw citizenship obtained by deception, even if the effect is to also withdraw citizenship of the Union, so long as the decision observes the principle of proportionality.
The applicant's Ukrainian nationality was withdrawn rendering him stateless, and subsequently a travel ban of 3 years was imposed on him due to a procedural violation of the border crossing rules.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.
A child is born in the Netherlands in 2016, and has resided there since, without a legal residence permit. A request was made on behalf of the child to determine that he has Dutch nationality, on the basis of direct application of article 1 of the 1961 Convention, as he would otherwise be stateless. The Court refuses, as it considers this to be a question of granting Dutch nationality, and not of determination of Dutch nationality, which the Court is not empowered to do.
