Question juridique clé
Whether the service company breached its contractual duties by reattaching the device despite recognizing the risk of the rigid connection.
Solution extraite
Yes. Once the technician recognized that the device should have been connected flexibly, he had to warn the owners and avoid reinstalling it rigidly without clarification.
Motifs extraits
The purpose of the service contract was to ensure proper functioning. A technician who detects a defect must report it even if checking the original installation was not expressly part of the contract.
