Questão jurídica principal
Whether the constitutional complaint was admissible despite the low value in dispute
Decisão extraída
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.
Fundamentação extraída
The court applied the statutory admissibility thresholds and limited review under the subsidiary constitutional complaint, which requires a clearly substantiated allegation of constitutional violations.
