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

The applicant, a Moroccan national who acquired French nationality, was sentenced to seven years’ imprisonment in 2013 for involvement in a conspiracy to carry out terrorist acts in France and other countries. He was deprived of his French nationality and was served with an expulsion order: despite requesting an interim measure under grounds of Article 3 ECHR he was returned to Morocco.

The applicant claimed, inter alia, that his removal violated his rights under Article 3 ECHR due to the risk that he would be exposed to ill-treatment in the event of his return and that his removal in breach of the European Court of Human Rights (the Court) interim measure violated Article 34 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: ECtHR
Date of decision:

After discovering that the applicant had omitted information when applying for Russian citizenship, his citizenship was annulled and an entry ban was enforced. 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 as guaranteed under Article 8 of the Convention. Furthermore, the expulsion of the applicant from Russian territory failed to respect the principle of proportionality, particularly given the lack of evidence of any threat to Russian national security posed by the applicant, thereby violating Article 8.

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

The Court held that it is not contrary to EU law for Member States to withdraw citizenship obtained by deception, even if the effect is to also withdraw citizenship of the Union, so long as the decision observes the principle of proportionality.

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: 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 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: Supreme Administrative Court
State: Ukraine
Date of decision:

The applicant was born in the Soviet Union on the territory of Russia. The facts as to where the applicant lived and when are disputed in the case. In 1999 he was issued a Ukrainian passport, but a court later established that the place and date of birth he indicated were not correct, and his passport was confiscated and destroyed. The authorities argued that the applicant ought to prove he never acquired Russian nationality or alternatively that he renounced his Russian nationality. 

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

The applicant's Ukrainian nationality was withdrawn rendering him stateless, and subsequently a travel ban of 3 years was imposed on him due to a procedural violation of the border crossing rules. The applicant argued that the travel ban is disproportionate, that he enjoys lawful residence in Ukraine, has very close ties with Ukraine, and that the ban interferes with his right to challenge the deprivation of nationality which rendered him stateless in person in court. 

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: Federal Administrative Court of Switzerland
Date of decision:

The applicant was a Syrian national of Kurdish ethnicity, who unsuccessfully applied for asylum in Switzerland. He subsequently claimed that he has been deprived of Syrian nationality and therefore ought to be recognised as stateless. The State Secretariat for Migration and the Court decided that he did not meet the standard of proof to substantiate his statelessness. 

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

Applicant is a refugee from Vietnam, whose refugee status was withdrawn after a number of criminal convictions, combined with the fact that he made a safe trip to Vietnam. He applied for a travel document for foreigners claiming that he is stateless or at least that his nationality status is unclear. The authorities maintained that he was still a Vietnamese national, but the Court sided with the applicant, insisting that the authorities should have taken more factors into account in considering the applicant's potential statelessness. 

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

The applicant was issued an assurance that she will acquire Austrian nationality if she renounced her former Serbian nationality, which she did. However, after the assurance was issued the applicant committed a number of administrative offences, leading to the assurance being withdrawn after the renunciation of the former nationality has already taken place, resulting in the applicant's statelessness. The Court emphasised the constitutional significance of a letter of assurance of acquisition of nationality, and sided with the applicant. 

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

The applicant acquired Austrian nationality by naturalisation in 1997, and renounced her Turkish nationality in that context. In 2018 it appeared that the applicant was listed on the voter registers for Turkish nationals abroad. She did not provide proof that she did not re-acquire Turkish nationality, and on that basis the Austrian authorities declared she has lost her Austrian nationality automatically due to acquisition of a foreign nationality. 

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

In order to acquire Austrian nationality, the applicant renounced her Turkish nationality in 1997. Over a decade later it came to light that she has re-acquired Turkish nationality in 1998, which according to Austrian law resulted in automatic loss of the Austrian nationality. She renounced her Turkish nationality again in 2009, but in 2010 the Austrian authorities confirmed that she was no longer Austrian since 1998. The Court found that this was not in violation of Austria's obligation to avoid statelessness since the applicant's statelessness was not caused by a decision of the  Austrian authorities. 

Court name: Gent Court of Appeal
State: Belgium
Date of decision:

The applicant arrived in Belgium in 2000 from Kazakhstan. He claimed to have lost his Kazakh nationality on the basis of a Kazakh law providing for such loss in case of permanent residence abroad for over 3 years without registration at the consulate. The Court studied the relevant Kazakh legislation as well as the implementing Presidential Decree, and found that such loss is not automatic, but requires a decision of a competent authority instead, and therefore the applicant's statelessness was not sufficiently substantiated. 

Court name: East-Brabant Court
Date of decision:

The applicant originates from Somalia and arrived to the Netherlands through Yemen as an unaccompanied minor. When testifying for his asylum application, he omitted to mention that he had lived in Yemen. He was granted a residence permit which later lead to his naturalisation, but the latter was withdrawn nearly 12 years later as the authorities found out about his history in Yemen. He argued that the denaturalisation is disproportionate in light of the CJEU Rottmann judgment, citing statelessness as one of the circumstances, and the court upheld his position. 

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

The applicant naturalised in the Netherlands in 2003, but the naturalisation was withdrawn in 2013 when the authorities found out she had a criminal conviction in Belgium in 2000 that she failed to mention in her naturalisation application. The applicant argued that the decision depriving her of her Dutch nationality is disproportionate, among others in light of EU law and Rottmann judgment, in particular due to her becoming stateless as a result, and the difficulties she may face re-acquiring her original Ghanaian nationality. The Court rejected the appeal and upheld the decision denaturalising the applicant. 

Court name: Court of North-Holland
Date of decision:

The applicant naturalised in the Netherlands, after having derived his legal residence from being a partner of a Dutch resident. His naturalisation was later withdrawn, as it appeared he has concluded a marriage and fathered a child with another person in Egypt while still deriving residence rights from his relationship in the Netherlands. The Court confirmed the legality of withdrawal, despite the applicant becoming stateless as a result.

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. 

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

The applicant was born in Poland to a Vietnamese mother. When she was 9 years old a Polish citizen formally recognised her as his daughter, and the local authority subsequently confirmed that she is a Polish citizen by birth. She was growing up as a Polish citizen until another 8 years later the central government authorities invalidated the confirmation of nationality by the local authority, as according to the Polish Citizenship Law changes in parenthood can only lead to acquisition of Polish citizenship if they take place within 1 year of birth. The applicant's arguments related to article 8 ECHR, best interests of the child, as well as long-term presumption of Polish citizenship due to no fault of the applicant, although the court dismissed all arguments.

Court name: Federal Administrative Court
State: Germany
Date of decision:

The case had been brought before the ECJ for a preliminary ruling, leading to its famous Rottman judgment (CJEU, C-135/08 Rottmann, judgment of 2 March 2010). The Federal Administrative Court rules on the case after the ECJ's judgment. The applicant lost his Austrian nationality when he naturalised in Germany, but his German naturalisation was later revoked as he committed fraud in the naturalisation procedure, rendering him stateless. The Federal Administrative Court upheld the administrative decision to withdraw the German nationality despite the uncertainty about the restoration of the Austrian nationality of the applicant.
