Key legal question
Whether the subsidiary constitutional complaint was admissible despite the low amount in dispute.
Extracted holding
The constitutional complaint was admissible; an ordinary civil appeal was not, because the amount in dispute did not reach the statutory threshold and no legal question of fundamental importance was invoked.
Extracted reasoning
Only CHF 20,961.60 remained disputed before the cantonal court, below the CHF 30,000 threshold. The case therefore could not proceed as an ordinary civil appeal, but subsidiarily as a constitutional complaint.
