Questione giuridica chiave
Whether the child could be regarded as a Swiss citizen and thus entitled to apply for a Swiss passport
Decisione estratta
Yes. The child was treated as Swiss under the statutory presumption of paternity while the husband’s paternity had not been challenged.
Motivazione estratta
The child was born during the marriage. Under the presumption of Art. 255 ZGB and Art. 1 BüG, nationality follows the legal father’s Swiss citizenship until the presumption is rebutted, even if another biological father is suspected.
