In-Depth Notes on Product Liability

Significance of Donoghue v Stevenson: Establishes the precedent for duty of care owed by manufacturers to consumers.

Stages: Manufacturer → Wholesaler → Retailer → Consumer → End User. Understanding relationships at each stage is crucial for establishing liability.

Contract (Sale of Goods Act 1979): Strict liability; no need to prove fault.
Negligence: Requires proof of duty of care, breach, and causation.
Consumer Protection Act 1987 (CPA): Generally strict liability with specific defenses.

Duty of Care: Manufacturers owe a duty to end-users and intermediaries in the production line (e.g., packers, distributors).
Key Case - Donoghue v Stevenson: Establishes manufacturers owe duty of care to consumers.
Cases to note: Stennett v Hancock (bystanders), and Murphy v Brentwood (no remedy for defective product).
Complex Structure Theory allows recovery for defective products if they provide property damage, although sometimes contested (e.g., Aswan Engineering v Lupdine).
Breach of Duty: Determined by reasonable care during product manufacturing. Relevant cases:
- Grant v Australian Knitting Mills: Breach inferred from defective product.
- Evans v Triplex Glass: Liability not established due to third-party fault.
- Kubach v Hollands and Hollis v Dow Corning: Warnings can alleviate liability.
Causation: Links negligence to the defect; relevant cases include Mason v Williams, emphasizing product integrity post-manufacture.
Pharmaceuticals: Issues like establishing causation, as seen in Loveday v Renton, where medical evidence was crucial.
Post-sale Duties: Duty to warn customers and potentially recall defective products as shown in Walton v British Leyland.
Defenses in Negligence: Consider various defenses applicable in negligence cases.

Historical Context: Implemented to comply with European Council directives; focuses on strict liability without needing to prove fault.
Key Points of CPA:
- Elements include standing to sue, identifying defendants, proving defect and damage, all with a limitation period of 3 years post-harm or within 10 years of circulation.

Defendants Under CPA: Include producers, own-branders, importers, and secondary defendants like suppliers.
Product Definition: Includes goods, components of products, and even services as exemplified in A v National Blood Authority.
Defect Criteria: Safety not meeting consumer expectations outlined by the CPA, considering marketing and warnings provided.

High-profile Cases: A v National Blood Authority illustrated public expectations about product safety versus industry standards and regulations.
Judicial Analysis: Studies how risk acceptance by consumers shapes legal outcomes, as seen in cases like Wilkes v DePuy International Ltd regarding hip replacement safety.

Particularly difficult in medical cases; highlights the need for strong scientific evidence linking the defect to harm.
Must prove that warnings would have been adhered to by consumers, with caution on intervening acts.

Section 5 coverage: Personal injury, property damage exceeding £275 with explicit exclusions of pure economic loss.

Development Risks Defense (s 4): Protects producers if defect wouldn't have been discovered with state-of-science knowledge at the time.
Other Defenses: Include compliance with EU obligations, issues of no supply, non-commercial production, and component defects.

Understanding of product liability requires knowledge of legal precedents, definitions of defects, applicable laws, and defenses. Each case may hinge on contextual facts and statutory interpretations, emphasizing the need for thorough legal analysis in product liability claims.
