Questione giuridica chiave
Whether the filing could be treated as a civil-law appeal despite the low amount in dispute
Decisione estratta
The ordinary civil-law appeal was unavailable because the minimum amount in dispute was not reached; the filing had to be treated as a subsidiary constitutional complaint.
Motivazione estratta
The amount in dispute was below CHF 30,000, so Art. 74(1)(b) BGG barred the civil-law appeal.
