Questione giuridica chiave
Whether the public-law appeal was admissible and the neighbor had standing to challenge the building permit.
Decisione estratta
The appeal was admissible in principle because the dispute concerned a building permit in an edified zone and the neighbor invoked norms protecting neighboring interests, but several complaints were insufficiently reasoned.
Motivazione estratta
A neighboring owner may challenge building permits when relying on provisions on dimensions, setbacks, height, or similar neighbor-protecting rules; however, constitutional arbitrariness allegations must be specifically substantiated.
