Kernrechtsfrage
Whether the chalet's floor slope defect escaped the warranty exclusion as a fraudulently hidden or unforeseeable defect.
Extrahierter Entscheid
The seller did not know of the slope defect, and the defect was not so serious or unforeseeable as to fall outside the agreed exclusion of warranty.
Extrahierte Begründung
The evidence did not show fraudulent concealment. The repair cost was modest, the chalet remained usable, and the defect was within the risks reasonably assumed for an old building sold at a reduced price.
