Kernrechtsfrage
Whether the cantonal court rightly declined to hear the tenant's request for lease extension due to insufficient reasoning in the appeal
Extrahierter Entscheid
Yes. The appeal had to identify the challenged findings and the evidentiary basis; merely referring to earlier submissions was insufficient.
Extrahierte Begründung
Art. 311(1) ZPO imposes a mandatory reasoning requirement. The tenant's appeal did not engage with the first-instance reasoning on lease extension and therefore did not satisfy a procedural admissibility condition.
