The applicant brought an appeal challenging the constitutionality of s.19 of the Irish Nationality and Citizenship Act 1956, which governs the procedure by which revocation of naturalisation is determined. The fact that the Minister initiated the revocation process, appointed the committee charged with conducting the inquiry and then reached the final decision, was unconstitutional according to the applicant, as it breached the right to fair procedures. The Court held that s.19 was unconstitutional because it did not provide the procedural safeguards required to meet the high threshold of natural justice applicable to a person facing such severe consequences, i.e. revocation of naturalisation.
The applicant's naturalisation request was denied due to a criminal record, even though he has resided in Luxembourg for decades and is a stateless person. The Court rules that the principle of avoidance of statelessness does not prevent States from setting conditions on access to naturalisation even for stateless persons.
The applicant was born in Yugoslavia on the territory of Croatia, to parents who were born on the territory of Bosnia and Herzegovina. The applicant's birth registration erroneously included an entry "Muslim", which was subsequently crossed out and replaced by a reference to his origin from Bosnia and Herzegovina. The applicant argued that he should have been registered as a Croatian national at birth, just like his brother was, and that denial of Croatian nationality status would mean that he became stateless after the dissolution of Yugoslavia.
The applicant was born in Madagascar and considered himself a French national, as he held French identity documents. However, his registration of French nationality was refused in 2005. He requested to be recognised as a French national, and submitted a number of arguments, among which his statelessness that would result from the refusal to recognise him as French. The Court dismisses his entitlement to French nationality.
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 challenged the Constitutionality of the Law on Citizenship, requiring Russian citizens who want to renounce their citizenship to have another citizenship, or a guarantee of being able to acquire a different citizenship. The Court determined that Russian citizens have the right to change their citizenship, but not an unconditional right to renounce it, referring to article 15 of the UDHR and the European Convention on Nationality. The prohibition on renunciation of Russian nationality with the aim of becoming a stateless person has been found to be in accordance with the Constitution of the Russian Federation.
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.
