The applicant's Ukrainian nationality was withdrawn rendering him stateless, and subsequently a travel ban of 3 years was imposed on him due to a procedural violation of the border crossing rules. The applicant argued that the travel ban is disproportionate, that he enjoys lawful residence in Ukraine, has very close ties with Ukraine, and that the ban interferes with his right to challenge the deprivation of nationality which rendered him stateless in person in court.
The applicant was born in Poland to a Vietnamese mother. When she was 9 years old a Polish citizen formally recognised her as his daughter, and the local authority subsequently confirmed that she is a Polish citizen by birth. She was growing up as a Polish citizen until another 8 years later the central government authorities invalidated the confirmation of nationality by the local authority, as according to the Polish Citizenship Law changes in parenthood can only lead to acquisition of Polish citizenship if they take place within 1 year of birth. The applicant's arguments related to article 8 ECHR, best interests of the child, as well as long-term presumption of Polish citizenship due to no fault of the applicant, although the court dismissed all arguments.
