Questione giuridica chiave
Admissibility of the federal filing as a subsidiary constitutional complaint and compliance with reasoning requirements
Decisione estratta
The filing was treated as a subsidiary constitutional complaint, but it did not meet the strict pleading requirements because it did not engage with the cantonal reasoning or show which constitutional rights were violated.
Motivazione estratta
The dispute value excluded an ordinary civil appeal, so only the subsidiary constitutional complaint was available. In that procedure, only constitutional rights may be invoked, and they must be specifically alleged and substantiated; the appellant failed to do so.
