Questione giuridica chiave
Whether Art. 58a BüG allows facilitated naturalization of later generations beyond the child and grandchildren of the Swiss mother line.
Decisione estratta
Art. 58a BüG can be construed, and if necessary supplemented, so as not to exclude the applicant solely because he belongs to a further generation; a gender-based disadvantage must be removed constitutionally.
Motivazione estratta
The wording is not clear, the legislative history does not show an intent to bar later generations, the purpose of the provision is to eliminate sex-based inequalities, and a constitutional interpretation or gap filling requires equal treatment of male and female descent lines.
