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.
