The case concerned the interpretation of Article 19 of the Directive (2011/95/EU, Qualification Directive). Specifically, the applicant had been granted subsidiary protection by the Austrian authorities on the mistaken basis that he was an Algerian national. The applicant was not responsible for the mistake, having rather declared throughout the proceedings that he was stateless. The CJEU held that under the Qualification Directive a State is under the obligation to revoke subsidiary protection if information emerges to prove that an individual never satisfied the requirements under the Directive.
The applicant's Ukrainian nationality was withdrawn rendering him stateless, and subsequently a travel ban of 3 years was imposed on him due to a procedural violation of the border crossing rules.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.
