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: Supreme Court
State: Ireland
Date of decision:

The applicant brought an appeal challenging the constitutionality of s.19 of the Irish Nationality and Citizenship Act 1956, which governs the procedure by which revocation of naturalisation is determined. The fact that the Minister initiated the revocation process, appointed the committee charged with conducting the inquiry and then reached the final decision, was unconstitutional according to the applicant, as it breached the right to fair procedures. The Court held that s.19 was unconstitutional because it did not provide the procedural safeguards required to meet the high threshold of natural justice applicable to a person facing such severe consequences, i.e. revocation of naturalisation.
