The municipality had standing to raise municipal-autonomy complaints; the appeal was otherwise admissible except for the standalone request for declaratory relief.
Motivazione estratta
The judgment affected the municipality in its sovereign powers because its refusal was annulled and it was ordered to decide anew. The declaratory request had no independent significance.
