The judgment is an answer to a general legal question as to whether Polish law allows the incorporation of foreign birth certificates where parents are of the same sex. The question was prompted by the authorities' refusal to transcribe into Polish law the foreign birth certificate of a child born to two mothers, both of whom are Polish nationals. The applicant argued that since lack of a transcribed birth certificate inhibits her child's access to a Polish passport, it in practice leads to a situation that is identical to statelessness.
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.
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 received asylum status as a stateless Palestinian, but his request to register his statelessness in the municipal civil records was rejected due to lack of evidence. He has an original UNRWA document and an ID from Lebanon, but they were considered insufficient proof of identity as well as of statelessness. The applicant complained that inability to affirm his statelessness violates his identity rights under article 8 ECHR, as well as his rights as a stateless person under EU law, both of which arguments didn't succeed.
