The case study highlights the importance of quality standards and implied duties in contracts. Chickfresh supplied poor-quality chicken to Eatwell, breaching their contract obligation. The exclusion clause in the contract, which stated that Chickfresh accepted no liability for any products supplied, was deemed illegal as it breached the quality standard mentioned by Eatwell. Additionally, the implied duty of supplying good-quality products imposed on Chickfresh. The case law supports this finding, citing the example of Saw Pipes vs. A Ltd., where the court held that there is an implied duty to maintain a certain level of quality in any product or service. As a result, Chickfresh is liable for the damages caused by their poor-quality chicken, and Eatwell has suffered a decline in sales due to the products' weakness compared to competitors.
