Key legal question
Whether the cantonal government exceeded its review powers and violated municipal autonomy by reassessing the applicant's language skills and granting citizenship.
Extracted holding
Yes. The government wrongly treated § 5 lit. d BüG as exhaustively limiting municipal discretion; the municipality could set a stricter but not excessive standard within its autonomous margin.
Extracted reasoning
The statutory language makes the listed requirements minimum conditions. Where no entitlement to naturalization exists, the Bürgerrat has discretionary power, but that discretion remains bounded by purpose and proportionality. Since language skills were only barely sufficient, the municipality did not exceed constitutional limits by denying the application.
