The applicant received Ukrainian nationality in 2008, and as part of the relevant evidence he submitted a court ruling establishing the fact of his permanent residency in Ukraine. Soon after, he renounced his Vietnamese nationality. In 2011 there was another court ruling which reversed the ruling about the applicant's permanent residence in Ukraine. This prompted the authorities to cancel the decision on the applicant's acquisition of Ukrainian nationality, rendering him stateless.
The Ukrainian nationality of the applicant and her two children was withdrawn in 2013, on the basis that the applicant committed fraud when acquiring the nationality in 2006. The allegation of fraud was based on the fact that a case file was missing from a Court which had earlier established the legal fact of the applicant's permanent residence. The applicant argued that the missing file is not her fault and cannot be construed as "fraud" on her side, and the Court agreed with her, annulling the decision that resulted in the loss of her and her children's nationality.
Applicant's Ukrainian nationality was withdrawn on the basis of voluntary acquisition of Canadian nationality. The applicant argued, among others, that he was not a Canadian national at the time of withdrawal of his Ukrainian nationality, and that he became stateless as a result of the withdrawal. Court dismissed his arguments as he did not provide sufficient evidence as to the circumstances of loss of his Canadian nationality.
