The applicant was born in the US, and his birth certificate indicated a Polish national as the father, and an unknown surrogate mother as the mother. Polish authorities refused to confirm the applicant acquired Polish nationality at birth as a child of a Polish parent, because the birth certificate is against the Polish public order, in particular the prohibition of surrogacy. The courts ruled in favour of the applicant, stating that confirmation of his Polish nationality on the basis of the birth certificate does not amount to validation of surrogacy.
After having been born, having lived, worked and and paid taxes in Austria his whole life the applicant was told he is not entitled to unemployment benefits as he did not have a right to work in Austria. While he was granted Austrian nationality upon application, he argued that he was entitled to unemployment benefits also in the time frame between becoming unemployed and acquiring the nationality, invoking his statelessness, and lack of implementation of Statelessness Conventions by Austria. The Court denies direct applicability of the Statelessness Conventions in Austria, and rules against the applicant.
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.
The applicant is a stateless Palestinian, whose naturalisation application was rejected based on the means of sustenance requirement. His dependants (wife and children) live in Jordan, where he is able to sustain them with his consistent employment in low-wage jobs - as undisputed by the authorities, and there was no indication of the family intending to relocate to Germany. The lower instance courts sided with the applicant that the hypothetical case of the family relocating to Germany need not be considered in the context of means of sustenance requirement, and the fact that the applicant never relied on social securities and has always been in gainful employment in Germany should be sufficient, but the Federal Administrative Court overruled those judgments and upheld the authorities decision to reject the applicant's naturalisation request, which left him stateless.
