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.
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.
The applicant was born in 1984 in the Republic of Croatia and her birth was registered, but she never acquired citizenship. The case concerns her subsequent acquisition of citizenship as a stateless person with permanent residence.
