Question juridique clé
Whether the owners were entitled to terminate the work contract without compensation after defective performance during construction.
Solution extraite
Yes. The defects made substitute performance under Art. 366(2) OR available, and the owners could also rely on the contractual termination path recognized by case law under Art. 366(1) OR.
Motifs extraits
The backfilling deviated materially from the contract, lacked agreed qualities, and the builder had made clear it would not cure the defect. A sufficient deadline and warning of termination had been given, and the defect was attributable to the contractor.
