Court name: Court of Justice of the European Union
State: Germany
Date of decision:

An Austrian national by birth transferred his residence to Germany and naturalised as a German national. The naturalisation in Germany had the effect, in accordance with Austrian law, of causing him to lose his Austrian nationality. The German authorities later withdrew the naturalisation with retroactive effect, on the grounds that the applicant had not disclosed that he was the subject of a criminal investigation in Austria on account of suspected serious fraud, and that he had thus obtained German nationality by deception. The Court held that it is not contrary to EU law for a Member State to withdraw nationality obtained by deception, even if it results in losing EU citizenship, so long as the decision observes the principle of proportionality. Observance of the principle of proportionality requires the person concerned to be afforded a reasonable period of time in order to try to recover the nationality of their Member State of origin.

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.
