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

The case concerns the loss of Danish nationality by the applicant who was born outside Denmark to a Danish mother and had spent less than a year in Denmark prior to her 22nd birthday, in accordance with the Law of Danish Nationality. The Court held that Article 20 TFEU, read in conjunction with Article 7 of the Charter of Fundamental Rights of the European Union, did not preclude such legislation by Member States, provided that the persons concerned had the opportunity to lodge, within a reasonable period, an application for the retention or recovery of nationality, for the authorities to examine the proportionality of the consequences of the loss of nationality from the perspective of EU law, and allow the retention or recovery of nationality. However, the period must extend for a reasonable time beyond the date by which the person concerned reaches the age stated in the legislation, and cannot begin to run unless the authorities have informed the person of the loss of nationality, and the right to apply for the maintenance or recovery of nationality.

Court name: European Court of Human Rights
State: Denmark
Date of decision:

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.
