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

The authorities refused to examine the applications of Dutch nationals, with dual nationality of a non-EU country, for renewal of their Dutch passports. The decision was based on the fact that they had lost their Dutch nationality because they possessed a foreign nationality and had their principal residence for an uninterrupted period of 10 years outside the Netherlands and the EU. The CJEU found that Member States may lay down rules regulating the loss of their nationality and, as a result, the loss of EU citizenship, where the genuine link between the person and that State is durably interrupted. Nevertheless, the loss of nationality must respect the principle of proportionality, which requires an individual assessment of the consequences of that loss for the person from the point of view of EU law.

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: Council of State of the Netherlands (Raad van State)
Date of decision:

The applicant is a dual Dutch/Moroccan national whose Dutch nationality was withdrawn on the basis of a criminal conviction for terrorist activities. The Court rejected the applicant's appeal, concluding, among others, that prevention of statelessness is a valid reason for differentiated treatment between those with a single and with multiple nationalities, and that withdrawal of nationality is not a punitive measure. Withdrawal of nationality in addition to the criminal sentence does not violate the principle that prohibits repeated punishments for the same action.  

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.

Court name: Vienna Administrative Court
State: Austria
Date of decision:

The applicant received assurance of obtaining Austrian nationality if she renounces her Estonian nationality. After the renunciation, it appeared that the applicant committed two administrative offences related to her driving, which in addition to the eight she committed previously were considered as an indication of her no longer fulfilling the public order requirement for naturalisation. This resulted in the withdrawal of assurance of obtaining Austrian nationality, leaving the applicant stateless. 

Court name: Council of State of the Netherlands (Raad van State)
Date of decision:

The applicant is a dual Moroccan-Dutch nationality, whose Dutch nationality was withdrawn as a consequence of his involvement in a terrorist organisation. The applicant argued that the legal ground for withdrawing nationality only affects dual nationals, who are almost always Dutch nationals with a non-Western background, and thus constitutes discrimination prohibited by the ECHR. The Court ruled that prevention of statelessness is a sufficient and objective justification of this distinction, and the distinction is therefore justified.
