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

The Court held that it is not contrary to EU law for Member States to withdraw citizenship obtained by deception, even if the effect is to also withdraw citizenship of the Union, so long as the decision observes the principle of proportionality.

Court name: Federal Administrative Court
State: Germany
Date of decision:

The case had been brought before the ECJ for a preliminary ruling, leading to its famous Rottman judgment (CJEU, C-135/08 Rottmann, judgment of 2 March 2010). The Federal Administrative Court rules on the case after the ECJ's judgment. The applicant lost his Austrian nationality when he naturalised in Germany, but his German naturalisation was later revoked as he committed fraud in the naturalisation procedure, rendering him stateless. The Federal Administrative Court upheld the administrative decision to withdraw the German nationality despite the uncertainty about the restoration of the Austrian nationality of the applicant.
