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 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.
