Key legal question
Whether the municipal appeal was admissible and whether municipal autonomy was violated by the department's review
Extracted holding
The municipality was entitled to appeal, but no autonomy violation was found because the department only corrected an arbitrary application of naturalization law.
Extracted reasoning
Municipal autonomy exists in naturalization, yet courts may intervene when the municipality misuses its discretion or applies the law in a way incompatible with the purposes of citizenship legislation.
