Kernrechtsfrage
Whether the buyer could rescind under Art. 107(2) OR despite the work-contract defect regime.
Extrahierter Entscheid
The buyer's right to withdraw had to be exercised under the specific work-contract rescission rules of Art. 368(1) OR, not directly under Art. 107(2) OR.
Extrahierte Begründung
The special rules of work contract law govern defective performance; Art. 107(2) OR only leads back to the contractual remedies under Art. 368 OR when the contractor refuses to cure.
