5â Types of defect

 

 

 

liability has arisen. Strict liability has supposed advantages over negligence

 

liability, of which the most obvious is that the claimant no longer needs

 

to establish whose negligence is to blame for the defective product. Rather,

 

the claimant needs to demonstrate that the product was ‘defective’ within the

 

statutory meaning of that word and that there is a causal link between the

 

defective product and the injury or damage he has suffered. In this respect,

 

it can be argued that strict liability has some of the same weaknesses as neg-

 

ligence in that the claimant still needs to identify a potential and viable

 

defendant22 and doubts have been raised as to whether strict liability is

 

really a significant improvement in this area. A further advantage claimed

 

for strict liability is an economic one; namely, that it facilitates risk spread-

 

ing through the use of product liability insurance, the premiums for which

 

can be recouped via an added factor to the costs of production and thereby

 

spread among all of the purchasers of the product via the price. The poten-

 

tial danger attached to the practice of risk spreading through insurance is

 

that insurance premiums may become prohibitively expensive, with some

 

manufacturers being forced to ‘go bare’ and not have product liability insur-

 

ance at all. This argument underpinned the so-called insurance crisis in the

 

United States but the Presidential Interactive Task Force23 found that there

 

was no evidence of any real emergency and thus it seems that this risk had

 

been overstated.

 

Negligence claims revolve around the alleged negligent behaviour of the

 

defendant while, in product liability, it is the defective nature of the product

 

that is key to the potential liability of the defendant. If liability is truly strict the

 

actions or intentions of the defendant are irrelevant. Naturally, this change of

 

emphasis requires a much closer scrutiny of the types of defect that may arise

 

and what will constitute a defective product.

 

Q5 Analyse the supposed advantages of strict liability over negligence.

5â Types of defect

Defects can generally be divided into three main categories: manufacturing defects, design defects and ‘duty-to-warn’ defects.24 While this is the simplest categorisation of defects, other commentators have developed more sophisticated analyses.

22 This is not necessarily the case in some US jurisdictions where the claimant can sue anyone who manufactured the product, who will then be held liable for a percentage of the claim equivalent to their percentage of the market. See Sindell v. Abbott Laboratories, 26 Cal. 3d 588 (1980).

23 Set up by President Ford to consider this issue.

24 For a very comprehensive analysis of types of defects see C.J. Miller and R.S. Goldberg, Product Liability (2nd edn, Oxford University Press, 2004). See also M. Griffiths, ‘Defectiveness in EEC product liability’ (1987) Journal of Business Law 222.

Negligence and the rise of product liability

 

 

(a)â Manufacturing defects

At its most basic, a manufacturing defect is the easiest to spot for it exists when an item ‘deviates from the norm’ of products being produced according to that design or on that production line. It can be proved statistically that a percentage of products, however minimal, in a production run will contain a manufacturing defect irrespective of the production method used or the efficiency of the quality assurance system employed during the manufacturing process. As the statistical frequency of such rogue products can be calculated accurately, the manufacturer can adopt a suitable quality control system to limit the occurrence of such rogues and recoup both the cost of the system and the cost of any injuries caused by defective products that reach the market via the price of the product.

Manufacturing defects can be evidenced in a variety of ways. The defective product may look different from others in the production run or might not perform in the way intended or have all of the characteristics of a perfect product. Equally, it may be that the product is adulterated by the presence of a foreign object such as a caterpillar in a tin of peas25 or an explosive detonator in a delivery of Coalite.26 Finally, a defective container is integral to the definition of a manufacturing defect, as, for instance, when a defective bottle containing carbonated drink explodes.

(b)â Design defects

A design defect is much more significant than a manufacturing defect and has potentially far wider-reaching consequences due to the fact that it involves not merely a small, statistically identifiable percentage of the production run but, rather, involves the whole of it. The contention is not that the product deviates from the legitimate specifications used by the manufacturer but rather that those specifications or design are themselves defective and present a hazard. The assessment of defectiveness in a design case is much more difficult as it involves considering viable alternatives, the utility of the product, the costs of changing the design, a risk-utility analysis of whether the benefits of the product outweigh the risk and severity of potential injury,27 and whether the state of scientific and technical knowledge prevailing at the time of production was such as to allow the producer to realise that the design posed unacceptable risks. This raises the vexed question of the unknowable defect which even the most diligent manufacturer cannot identify. The issues of the state of the art and of the availability of a development risk defence is of particular concern

in industries such as pharmaceuticals, which depend heavily on research and

 

development to develop new products and to which there is likely to be a risk

 

attached. A prime example of a development risk was the drug Thalidomide,

 

which, when used by pregnant mothers, caused limb damage to the foe-

 

tus resulting in a large number of children born with deformed or shortened

 

limbs.28 In the event, their plight acted as a driving force in the demand for

 

strict product liability,29 as a claim in negligence, the legal regime prevailing

 

at the time, would have failed.30 Somewhat naturally, manufacturers, particu-

 

larly in industries such as pharmaceuticals, feel the need for a development risk

 

defence, both to protect them from liability for injuries caused by unknowable

 

defects and also to encourage the research and development of new products.

 

By contrast, consumer bodies argue that such a defence should not be allowed

 

and that a manufacturer who produces a product should be liable for all injuries

 

caused by using it irrespective of whether the manufacturer could have known

 

of the underlying defect. Their argument is that the injured user deserves com-

 

pensation either way and that if the manufacturer takes the profits from the

 

product, he should also be prepared to accept liability for any injuries caused by

 

it. Needless to say, there is no easy solution to this difference of opinion. It is no

 

surprise that the debate about whether to allow a development risk defence in

 

the EC Directive continued for some years and was ultimately resolved only by

 

allowing Member States the option to choose whether they wished to adopt the

 

defence into their national legislation.31

(c)â Duty to warn defects

The third type of defect is the so-called ‘duty to warn’ defect, which occurs when a producer has failed to provide appropriate instructions for the safe use of the product and appropriate warnings about any known risks that the product may

28 We will return to the issue of development risks when we consider the defences permitted under the EU Product Liability Directive.

29 When establishing the Royal Commission on Civil Liability and Compensation for Personal Injury, the then Prime Minister, Edward Heath, stated ‘The Government has been considering proposals made from time to time in the past, which are now particularly relevant in the light of the Report of the Robens Committee on Health and Safety at Work and in connection with the recent concern over the thalidomide cases, that there should be an inquiry into the basis of civil liability in the United Kingdom for causing death or personal injury.’

30 The Thalidomide victims in the United Kingdom received an out-of-court settlement of £20 million in respect of their claim.

31 Only Luxembourg and Finland decided against a development risk defence and thus producers in those countries have liability for all products. In Spain, manufacturers are liable for development risks in food and pharmaceutical products, while in France producers are liable for development risks in products derived from the human body. In Germany, producers are liable for development risks in pharmaceutical products as a consequence of the Thalidomide issue. Germany was the country worst affected by this drug, which was known there as Contergan. See Report from the Commission on the Application of Directive 85/374 on Liability for Defective Products, COM(2000)893 final and also G. Howells and S. Weatherill, Consumer Protection Law (2nd edn, Ashgate Publishing Ltd, Aldershot, 2005).
