Questione giuridica chiave
Whether the subsidiary constitutional complaint was admissible against the cantonal judgment.
Decisione estratta
The complaint was admissible because the matter was pecuniary and below the threshold for an ordinary civil appeal; only constitutional rights could be invoked.
Motivazione estratta
The dispute value was CHF 3,759.15, so ordinary civil appeal was excluded; subsidiary constitutional complaint under the BGG was therefore available.
