Kernrechtsfrage
Whether the contractor proved that the defect-removal costs were excessive under Art. 368 OR
Extrahierter Entscheid
The contractor had to prove the circumstances showing that the repair costs were excessive, and it failed to do so.
Extrahierte Begründung
Under Art. 368 OR, excessiveness exists only where the costs are disproportionate to the benefit of remedying the defect. The contractor did not sufficiently substantiate this point or present timely, adequate evidence.
