Court name: Conseil d'État
State: France
Date of decision:

Article 25 of the French Civil Code provides that an individual may be stripped of their French nationality where, inter alia, it was acquired by naturalization and where the individual has been convicted of a crime that constituted an attack on the fundamental interests of France or an act of terrorism. Deprivation of French nationality is not allowed where it would render the individual stateless. The applicant was deprived of his French nationality, which he had acquired by naturalization, following a decision of the Paris Criminal Court (Tribunal de Grande Instance de Paris) convicting him for his participation in an association of criminals with a view to preparing an act of terrorism. That court found that he had joined a terrorist group and participated in training and armed operations of that group. The Council of State (Conseil d’État) upheld the decree of deprivation of nationality because the applicant held Algerian nationality since birth and could not be deprived of it since the Algerian code of nationality only authorises the deprivation of nationality for persons who have acquired it after birth. Therefore, the loss of French nationality would not render him stateless and was thus not illegal under French law. The Council of State also ruled on the proportionality of the decree with regard to the European Convention on Human Rights and found that, given the seriousness of the crimes committed by the applicant, the challenged decree did not disproportionately infringe the right to respect for his private life guaranteed by Article 8 of the ECHR.

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

The applicant challenged a decision depriving him of his British citizenship and excluding him from the United Kingdom because of his alleged involvement and link to terrorist-related activities. After failing in his appeals to the High Court, Court of Appeal and the Special Immigration Appeal Tribunal, the applicant complained to the European Court of Human Rights (‘the Court’) under Articles 8 and 14. The Court rejected all of the applicant’s complaints, finding them to be manifestly ill-founded, and declared the application inadmissible.

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

Five applicants of dual nationality, convicted in 2007 of participating in a criminal association in a terrorist context, were stripped of their French nationality in October 2015 by Prime Minister decrees. The Court held that the decision to forfeit the applicants’ French nationality did not have a disproportionate impact on their private lives and therefore was not in violation of Article 8 of the Convention.

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

Two applications (joined before the Court) concerned the removal of and the refusal to exchange passports, leaving the applicants stateless and without identity documentation, after the relevant Russian authorities found their Russian citizenship to be granted erroneously. The Court held the withdrawal of identity documents, which affected the exercise of their rights and freedoms in their daily lives, was a violation of Article 8 of the Convention.

Court name: Supreme Administrative Court
State: Poland
Date of decision:

The applicant was born in the US, and his birth certificate indicated a Polish national as the father, and an unknown surrogate mother as the mother. Polish authorities refused to confirm the applicant acquired Polish nationality at birth as a child of a Polish parent, because the birth certificate is against the Polish public order, in particular the prohibition of surrogacy. The courts ruled in favour of the applicant, stating that confirmation of his Polish nationality on the basis of the birth certificate does not amount to validation of surrogacy.

Court name: Constitutional Court of Austria (Verfassungsgerichtshof)
State: Austria
Date of decision:

The applicant acquired Austrian nationality in 1995 and renounced her former Turkish nationality in 1996 as a condition for retaining the Austrian nationality. In 2018 the Austrian authorities declared that she has no longer been an Austrian national since 1997 as it appeared that she voluntarily re-acquired her Turkish nationality at that time, which is a ground for automatic loss of Austrian nationality. The Court set aside the determination of loss of Austrian nationality as it did not carry out a proportionality test on the basis of the Tjebbes judgment.

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

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.
