The applicant acquired Austrian nationality in 1995 and renounced her former Turkish nationality in 1996 as a condition for retaining the Austrian nationality. In 2018 the Austrian authorities declared that she has no longer been an Austrian national since 1997 as it appeared that she voluntarily re-acquired her Turkish nationality at that time, which is a ground for automatic loss of Austrian nationality. The Court set aside the determination of loss of Austrian nationality as it did not carry out a proportionality test on the basis of the Tjebbes judgment.
The applicant received asylum status as a stateless Palestinian, but his request to register his statelessness in the municipal civil records was rejected due to lack of evidence. He has an original UNRWA document and an ID from Lebanon, but they were considered insufficient proof of identity as well as of statelessness. The applicant complained that inability to affirm his statelessness violates his identity rights under article 8 ECHR, as well as his rights as a stateless person under EU law, both of which arguments didn't succeed.
