The case concerns Danish authorities’ decisions to deprive a dual national of his Danish citizenship and to deport him, following conviction for receiving training with ISIS. This was found to be compliant with Article 8 ECHR. The Court reasoned that deprivation of nationality was not arbitrary, that there had been sufficient opportunities to appeal, and that the crime in question, terrorism, was a serious one that endangered human rights. The punishment of deprivation of nationality was found to be proportionate. The Court also found that deprivation of nationality in this instance did not result in impermissible consequences as it did not render the applicant stateless.
An Austrian national by birth transferred his residence to Germany and naturalised as a German national. The naturalisation in Germany had the effect, in accordance with Austrian law, of causing him to lose his Austrian nationality. The German authorities later withdrew the naturalisation with retroactive effect, on the grounds that the applicant had not disclosed that he was the subject of a criminal investigation in Austria on account of suspected serious fraud, and that he had thus obtained German nationality by deception. The Court held that it is not contrary to EU law for a Member State to withdraw nationality obtained by deception, even if it results in losing EU citizenship, so long as the decision observes the principle of proportionality. Observance of the principle of proportionality requires the person concerned to be afforded a reasonable period of time in order to try to recover the nationality of their Member State of origin.
The applicant's Ukrainian nationality was withdrawn rendering him stateless, and subsequently a travel ban of 3 years was imposed on him due to a procedural violation of the border crossing rules.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 has been residing in Russia since 2002 with a Russian passport. His request to renew his passport in 2011 was denied, reason being that his previous passport was not issued in accordance with applicable rules, the latter having been confiscated on the basis of the same decision. The refusal to renew the applicant's passport rendered him stateless, which was considered by the court as a strong argument to rule in favour of the applicant and declare the decision of the responsible authority unlawful.
The applicant is a former USSR citizen, who has been residing on the territory of Russian Federation since 1990. He has received an "insert" into his passport in 1994 as evidence of him being recognised as a Russian citizen, which was a standard procedure at a time. In 2011 a "verification" took place - a policy that resulted in questioning of many citizenships acquired after the fall of the Soviet Union, including the applicant. The Court sided with the applicant, considering among others that refusal to recognise him as a Russian citizen would result in his statelessness.
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.
The case concerns an applicant who was a Ukrainian citizen and a resident of Crimean Peninsular at the time of Crimean annexation to Russia. He was originally issued with a Russian passport in 2014, which was subsequently confiscated as a government initiated verification procedure established he did not comply with the relevant residency requirements to be considered a Russian citizen. The Court, on appeal, sided with the applicant, confirming his right to Russian citizenship despite not complying with all the formal requirements.
In its reasoning the Court relied heavily on the importance to take all the relevant and factual evidence when establishing the legal fact of residence, and basing it on a broad range of evidence about the person's personal and professional life, as well as intentions, not the merely the strict formalistic rules of residence registration, especially in light of consequences of denial of access to citizenship for the applicant, and the circumstances of state succession. The Court refers extensively to international legal instruments, even those Russia hasn't ratified, such as the European Convention on Nationality and its anti-statelessness safeguards, the CoE Convention on the Avoidance of Statelessness in Relation to State Succession, as well as art. 15 UDHR, and other international legal instruments.
