Kernrechtsfrage
Whether the federal appeal was admissible in light of the disputed amount and procedural requirements.
Extrahierter Entscheid
The appeal was admissible because the value in dispute exceeded the statutory threshold when calculated from the contested annual rent difference multiplied by 20.
Extrahierte Begründung
In tacitly renewed leases, the annual rent difference is multiplied by 20 for the value in dispute. The relevant contested amount exceeded CHF 8,000.
