The applicant is a dual Dutch/Moroccan national whose Dutch nationality was withdrawn on the basis of a criminal conviction for terrorist activities.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.
The applicant's naturalisation request was denied due to a criminal record, even though he has resided in Luxembourg for decades and is a stateless person. The Court rules that the principle of avoidance of statelessness does not prevent States from setting conditions on access to naturalisation even for stateless persons.
The applicant is a dual Moroccan-Dutch nationality, whose Dutch nationality was withdrawn as a consequence of his involvement in a terrorist organisation.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.
