Kernrechtsfrage
Whether the subsidiary constitutional complaint was admissible despite the low amount in dispute.
Extrahierter Entscheid
Only the subsidiary constitutional complaint was available because the amount in dispute was below CHF 15,000 and no legal question of fundamental importance arose.
Extrahierte Begründung
Under Art. 85 and 113 BGG, ordinary appeal routes were unavailable; the appellant correctly used constitutional complaint.
