This case concerns an Estonian national who renounced her nationality on the basis of an assurance that she would be granted Austrian nationality once proof of her renunciation was given. This assurance was revoked on the grounds that the applicant had committed road traffic offences, leaving the applicant stateless. In its judgment, the CJEU confirms that the situation at issue in the main proceedings falls within the ambit of EU law, and concluded that the authorities' decision to revoke an assurance to grant Austrian nationality was not compatible with the principle of proportionality.
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.
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.
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the assurance was issued the applicant committed a number of administrative offences, leading to the assurance being withdrawn after the renunciation of the former nationality has already taken place, resulting in the applicant's statelessness.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.
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.
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.
