The applicant was born in the Soviet Union on the territory of Russia. The facts as to where the applicant lived and when are disputed in the case. In 1999 he was issued a Ukrainian passport, but a court later established that the place and date of birth he indicated were not correct, and his passport was confiscated and destroyed. The authorities argued that the applicant ought to prove he never acquired Russian nationality or alternatively that he renounced his Russian nationality.
The applicant arrived to Poland from Ukraine shortly after the dissolution of the USSR. His application for facilitated naturalisation as a stateless person was rejected in 2010 as his statelessness was not evident. The state authorities presented evidence of applicant's Ukrainian citizenship which included a letter from Ukrainian consulate in Poland. The Court ruled that self-declaring as stateless does not have legal significance in the context of access to facilitated naturalisation, and held it against the applicant that he did not effectively challenge the state authorities' evidence of his Ukrainian nationality.
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 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.
