Kernrechtsfrage
Whether the federal appeal was admissible as a civil-law appeal or subsidiary constitutional complaint.
Extrahierter Entscheid
A civil-law appeal was unavailable because the value in dispute did not reach CHF 30,000 and no legal question of fundamental importance arose; the filing was treated as a subsidiary constitutional complaint.
Extrahierte Begründung
The statutory prerequisites for the ordinary civil appeal were not met, so only the subsidiary constitutional complaint remained possible.
