Final answer:
No, the owners of DJI are not right. Ziggy Sounds Ltd can sue for breach of contract.
Step-by-step explanation:
The owners of DJI are not right. In this case, Ziggy Sounds Ltd and DJI have a longstanding business relationship, and their agreements have always been based on DJI's standard form contract. This contract has always included the same promises regarding the quality of the goods. Although DJI's new owners added the phrase 'This agreement is subject to formal contract' to the latest contract, the workers at DJI proceeded with creating and delivering the requested component. By doing so, they accepted the terms of the contract, including the promises regarding the quality of the goods. Therefore, DJI can be held responsible for the defective component and Ziggy Sounds Ltd can sue for breach of contract.
