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The applicant's Ukrainian nationality was withdrawn rendering him stateless, and subsequently a travel ban of 3 years was imposed on him due to a procedural violation of the border crossing rules.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.
The applicant received assurance of obtaining Austrian nationality if she renounces her Estonian nationality. After the renunciation, it appeared that the applicant committed two administrative offences related to her driving, which in addition to the eight she committed previously were considered as an indication of her no longer fulfilling the public order requirement for naturalisation. This resulted in the withdrawal of assurance of obtaining Austrian nationality, leaving the applicant stateless.
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.
Request to have nationality changed from "unknown" to "stateless" denied, as it cannot be ruled out that the applicant's father has Macedonian nationality. Applicant did not provide enough evidence to determine statelessness.
