Questione giuridica chiave
Whether the constitutional complaint was admissible despite the low value in dispute
Decisione estratta
The ordinary civil appeal was unavailable because the value in dispute did not reach CHF 30,000 and no legal question of fundamental importance was raised; the filing was therefore treated as a subsidiary constitutional complaint.
Motivazione estratta
The court applied the statutory admissibility thresholds and limited review under the subsidiary constitutional complaint, which requires a clearly substantiated allegation of constitutional violations.
