Kernrechtsfrage
Whether the cantonal court violated the right to be heard by insufficiently reasoning its decision on the landlord's alleged fault and mitigation measures.
Extrahierter Entscheid
No. The court was not required to discuss the prolongation causes or fault once it denied damages for lack of proof of loss.
Extrahierte Begründung
The right to be heard requires only brief reasoning on relevant points. Since the duration of the works was treated as a whole and the damages claim failed for lack of proof of damage, fault became irrelevant.
