Kernrechtsfrage
Whether the federal civil appeal was admissible despite the low amount in dispute and the tenant's reliance on a fundamental legal question.
Extrahierter Entscheid
The court left that point open because the appeal was inadmissible for other reasons.
Extrahierte Begründung
Even assuming a fundamental question existed, the appeal failed because the cantonal cassation court had reviewed only for arbitrariness and the appellant attacked only that judgment, not the first-instance decision as required by the unit of proceedings.
