The case concerns Danish authorities’ decisions to deprive a dual national of his Danish citizenship and to deport him, following conviction for receiving training with ISIS. This was found to be compliant with Article 8 ECHR. The Court reasoned that deprivation of nationality was not arbitrary, that there had been sufficient opportunities to appeal, and that the crime in question, terrorism, was a serious one that endangered human rights. The punishment of deprivation of nationality was found to be proportionate. The Court also found that deprivation of nationality in this instance did not result in impermissible consequences as it did not render the applicant stateless.
After discovering that the applicant had omitted information when applying for Russian nationality, his nationality was annulled and an entry ban was enforced. The Court applied a two-pronged approach to assess whether the deprivation of the applicant’s nationality was an interference with his right to private and family life, which assessed (i) the consequences for the applicant, and (ii) whether the measure was arbitrary. In light of the far-reaching consequences of this decision and its apparent arbitrary nature, the Court held that the annulment interfered with the applicant's rights guaranteed under Article 8 ECHR. Further, the Court found that the expulsion of the applicant from Russian territory failed to respect the principle of proportionality, given the lack of evidence of any threat to Russian national security posed by the applicant, thereby violating Article 8.
An Egyptian national, who resided in Malta and acquired Maltese nationality, was granted authorisation to renounce his Egyptian nationality as he could not hold dual nationality while in Malta. He was deprived of his Maltese nationality years later, following a decision that found that he had obtained his Maltese nationality from his first marriage through fraud. The Court found that there was no violation of Article 8 and held that the decision to deprive the applicant of his Maltese nationality did not adversely affect him.
