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 was born in the Russian Federation and his birth was not duly registered. Lacking identity documents and unable to prove his nationality, he was detained in Ukraine for the purpose of expulsion. The Court held that the authorities did not act diligently when they waited almost eleven months to contact the Russian embassy and obtain documentation to evidence the applicant's Russian nationality, and failed to review the lawfulness of his detention and to provide an effective remedy, in violation of Articles 5(1), (4) and (5) ECHR.
