Questão jurídica principal
Whether the appeal against the cantonal judgment was admissible and the municipality could invoke autonomy.
Decisão extraída
The municipality had standing to complain of an autonomy violation; the appeal was otherwise admissible, except for the separate declaratory request.
Fundamentação extraída
The judgment affected the municipality's sovereign powers, and the naturalization matter left it a sufficiently broad margin of appreciation to justify autonomy protection.
