An Austrian national by birth transferred his residence to Germany and naturalised as a German national. The naturalisation in Germany had the effect, in accordance with Austrian law, of causing him to lose his Austrian nationality. The German authorities later withdrew the naturalisation with retroactive effect, on the grounds that the applicant had not disclosed that he was the subject of a criminal investigation in Austria on account of suspected serious fraud, and that he had thus obtained German nationality by deception. The Court held that it is not contrary to EU law for a Member State to withdraw nationality obtained by deception, even if it results in losing EU citizenship, so long as the decision observes the principle of proportionality. Observance of the principle of proportionality requires the person concerned to be afforded a reasonable period of time in order to try to recover the nationality of their Member State of origin.
The applicant is a stateless Palestinian from Lebanon, who was denied statelessness status recognition as he was found to fall under the exclusion grounds of the 1954 Convention, even after leaving the territory under UNRWA mandate.
The applicant was born in China and is of Tibetan origin. He fled China to Nepal, and then made his way to Belgium through India on a fake passport. His asylum applications failed, he has been detained with a view to deportation to China, but had been released due to the Chinese authorities not issuing the necessary documents. The applicant also unsuccessfully attempted to organise voluntary return through IOM, contacting authorities of China, India, and Nepal. These facts convinced the Court to recognise the applicant as stateless.
The applicant was born in Italy to parents born in former Yugoslavia. His stateless status was denied on the basis that he did not make enough efforts to be recognised as a national of either Italy, Croatia or Macedonia.
