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

JY, an Estonian national, applied for Austrian nationality. As Austria operates a 'single nationality' approach, JY renounced her Estonian nationality after receiving an assurance that she would be granted Austrian nationality once proof of her renunciation was given. This assurance was subsequently revoked due to the applicant committing two road traffic offences, leaving her stateless. In its judgment, the CJEU confirmed that the situation falls within the scope of EU law, and that the authorities' decision to revoke an assurance to grant Austrian nationality was incompatible with the principle of proportionality considering the gravity of the offences committed. The Court noted that the concepts of ‘public policy’ and ‘public security’ must be interpreted strictly and clarified their meaning, concluding that it did not appear that JY represented a genuine, present and sufficiently serious threat affecting one of the fundamental interests of society or a threat to public security in Austria. It also held that traffic offences, punishable by mere administrative fines, cannot be regarded as capable of demonstrating that the person is a threat to public policy and public security which may justify the permanent loss of their EU citizenship.

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.

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.
