Product liability in prosthetics: Changes in the law 2016

The Consumer Protection Act (1987) (CPA) makes a producer strictly liable for personal injury, death or damage caused by a defective product. Although fault is not a requirement, the consumer (patient) must prove the defect, the injury and a causal link between them.

The court found in favour of the claimants in what was perceived to be a harsh decision at the time. In an 82-page judgement, it was argued under the Act and the European Union product liability safety directive, that the blood products were defective and that the public was entitled to expect that transfused blood should be free of infection, even though there was no reasonable means that the NBA could have used to identify the infection.
