The applicant attempted to renounce his Russian nationality as being a national of Russian Federation violated his religious beliefs. The request was refused, as he failed to provide proof of having another nationality or a guarantee of acquisition of another nationality upon renouncing his Russian nationality. The Constitutional Court ruled against the applicant, stating that prohibition on renunciation of a nationality that results in statelessness is in line with international norms, and that the mere possession of Russian nationality cannot be seen as a violation of religious beliefs.
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.
The applicant attempted to renounce her Russian nationality without proof of having another nationality or a guarantee of acquiring one. The Court decided that the constitutional right to change one's nationality does not amount to an absolute right to unilaterally renounce a nationality, and that it is not unconstitutional to impose a number of conditions on nationals before allowing renunciation, among which the condition of having secured an alternative nationality. Prohibition of renunciation of nationality with an aim of becoming stateless has been ruled as complying with international standards, in particular with the European Convention on Nationality.
