Court name: Council of the State
State: Greece
Date of decision:

The case concerns the rejection of an application for re-acquisition of Greek nationality by a woman who voluntarily renounced her nationality following the acquisition of foreign nationality by marriage, in spite of the fact that her husband was allegedly a stateless person of Palestinian origin. The court ruled that the competent authorities had acted legitimately by rejecting the application.

Court name: Court of Appeal
Date of decision:

The applicant applied for British citizenship on the basis of s.4B of the British Nationality Act 1981 (which does not allow the grant of British citizenship when the applicant already has another nationality), relying on a letter from a Pakistani Consulate confirming that his Pakistani nationality was cancelled. The Court of Appeal reversed the lower court’s decision, which had been in favour of the applicant, on the basis that (1) it failed to apply the principle that the person's nationality was to be determined by reference to the actual law of the state on the basis of expert evidence, not what agencies of the state might assert about that person's nationality; and (2) the lower court’s reading of Pakistani law was mistaken.

Court name: Administrative Court in Split
State: Croatia
Date of decision:

In 2012, the applicant received a guarantee that he would receive Croatian citizenship if he would renounce his UK nationality, and he proceeded with the renunciation. In 2013, criminal proceedings against the applicant were initiated, and his naturalisation application was thus postponed and subsequently, after the criminal conviction, rejected - leaving him stateless. The Court ruled against the applicant, finding that naturalisation is a discretionary power of the state and not a right of an individual, and that all the naturalisation requirements, including renunciation of previous nationality and lack of criminal record, need to be met cumulatively for a successful naturalisation.

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

The applicant received an assurance of acquiring Austrian nationality if she renounces her former, Serbian, nationality. Shortly after the renunciation the applicant lost her job and was unable to find alternative employment due to her statelessness, which resulted in her no longer complying with the income requirement for acquiring Austrian nationality. The Court declares unconstitutional the law which requires continuous fulfilment of all the conditions for naturalisation, even after Austrian nationality has been conditionally granted and the former nationality has been renounced. 

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

When naturalising in the Netherlands the applicant committed to renouncing his original nationality. The Dutch authorities have withdrawn his naturalisation as he missed the deadline for renunciation, but by then the applicant had already taken steps to renounce his original nationality, albeit after the deadline, thus leading to the decision of the Dutch authorities potentially rendering him stateless. The Court considered the direct effect of ECN in the Dutch legal order, as well as whether the applicant’s case amounted to fraudulent acquisition of nationality, which would potentially justify rendering him stateless under the ECN. The Court ordered the authorities to take a new decision, which takes into the account the developments that took place after the deadline, and referring to the risk of statelessness.
