Question juridique clé
Whether the federal filing was admissible as a civil law appeal or subsidiary constitutional complaint.
Solution extraite
A civil law appeal was unavailable because the statutory minimum value in dispute was not reached; the filing had to be treated as a subsidiary constitutional complaint.
Motifs extraits
The amount in dispute was below CHF 15,000, so Art. 74(1)(a) BGG barred the ordinary civil appeal; the remaining remedy was the subsidiary constitutional complaint.
