Harm caused by a defective product – and liability for it – could potentially be attributed to any business within the supply chain. Each case will have its nuances and this evidence will be used to identify which party is to blame. For instance, if a product is faulty, the blame may fall with the manufacturer, but if a faulty element in the product came from a supplier, the supplier or both parties may be liable. Meanwhile, a contaminated food product causing illness could mean both manufacturer and retailer are liable for failing to take necessary precautions.
