Court name: Administrative Court of Luxembourg
State: Luxembourg
Date of decision:

The applicant appplicant was born in Russia and renounced his Russian nationality in 2000. He applied for a statelessness status in Luxembourg in 2008, but it was discovered that he had applied for asylum status in the Netherlands in 2006, which was rejected, so Luxembourg transferred the applicant to the Netherlands under the Dublin regulation. The applicant returned several times to Luxembourg and was sent back to the Netherlands. He made a repeated application for statelessness status in 2014, where the courts accepted his argument that statelessness status determination doesn't fall within the scope of the Dublin regulations, and the court also accepted that his voluntary renunciation of Russian nationality does not exclude him from protection under the 1954 Convention. 

Court name: Constitutional Court of Austria (Verfassungsgerichtshof)
State: Austria
Date of decision:

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.
