Kernrechtsfrage
Whether the federal appeal was admissible, especially on amount in dispute and procedural requirements.
Extrahierter Entscheid
The appeal was admissible because the amount in dispute exceeded CHF 15,000 and the formal requirements were met.
Extrahierte Begründung
For lease disputes, the value in dispute is calculated by reference to the rent for the period until the next possible termination; here, three years of rent exceeded the statutory threshold.
