Kernrechtsfrage
Whether the Federal Supreme Court overlooked a relevant fact under Art. 121 let. d LTF
Extrahierter Entscheid
No relevant fact was overlooked; the alleged omission would not have changed the outcome.
Extrahierte Begründung
The court had already based its prior judgment on the landlord's stated ground in the official notice of initial rent and on the tenants' failure to request an absolute-method yield calculation. The building's age was therefore not decisive.
