Court name: Supreme Administrative Court
State: Ukraine
Date of decision:

The applicant was born in the Soviet Union on the territory of Russia. The facts as to where the applicant lived and when are disputed in the case. In 1999 he was issued a Ukrainian passport, but a court later established that the place and date of birth he indicated were not correct, and his passport was confiscated and destroyed. The authorities argued that the applicant ought to prove he never acquired Russian nationality or alternatively that he renounced his Russian nationality. 

Court name: Constitutional Court of Austria (Verfassungsgerichtshof)
State: Austria
Date of decision:

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.
