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 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.
