and one is alleged to be undiscoverable even though the other has been discovered.76

Since the English Hepatitis C decision, the Austrian Supreme Court has held that a coffee machine which caught fire for no clear reason was defective, even though the claimant could not explain the mechanism which led to the outbreak of the fire.77 The defendant ran the development risks defence on the basis that, since 60,000 similar machines had been supplied without any similar incidents, the defect must have been undiscoverable. The Court rejected this argument since the defendant had not proved that it was unknowable at the relevant time that coffee machines could catch fire by reason of ‘unavoidable and perhaps undiscoverable defects’. This is a firm application of the defence in keeping with the goals of consumer protection and liability without fault.

Unresolved issues

State of knowledge

The Court of Justice did not resolve the classic difficulty of defining the ‘state of scientific and technical knowledge’. As discussed above, the notion that the most advanced idea, however abstruse, counter-intuitive or unsupported by evidence, may set the standard is puzzling.78 It is unclear how such an approach fits with the concept of a ‘state’ of knowledge, a phrase which seems to imply some consensus or settled basis.

Accessibility

As a fetter on the effect of such an approach (and, as we have seen, introducing a two-stage test of uncertain textual provenance) the Court of

76Suppose a drug can cause damage to joints and to the liver. If the capacity to cause liver damage is discoverable in 2000 but that to cause damage to joints in 2003, it is uncertain when the defence is lost in relation to the latter. Claimants will attempt to define the defect as the capacity to cause injury per se. Defendants will wish to define the injury with more specificity. This question goes to the definition of defect but clearly affects the availability of the defence. There is no authority on the question.

78Contrast the approach of the US Supreme Court in Daubert v Merrell Dow Pharmaceuticals Inc 509 US 579 (1993) which sought to refine the concept of the state of scientific knowledge, in particular by insisting that the materials relied upon by expert witnesses in their evaluation of scientific controversies should have undergone peer review.

Justice qualified its view that Article 7(e) is directed ‘unreservedly, at the state of scientific and technical knowledge, including the most advanced level of such knowledge’ by the requirement that such knowledge must have been accessible.79 Burton J was content to follow the qualification although he added no elucidation of the meaning of ‘accessible’ to the gloss imposed on the literal wording of the Directive by the Court of Justice. It is implicit in his judgment that the following would not be considered accessible: (i) an unpublished document and (ii) unpublished research not available to the general public retained within the laboratory or research department of another enterprise. It is not clear whether these are intended to be exhaustive. By inference publication is generally a prerequisite for accessibility.

Does it follow that anything recorded on a searchable database is presumed to be within the producer’s knowledge? Or only that in the same language as that spoken by the producer? Or only that contained in the databases which a producer of products of the type in question is in the habit of searching? It is easy to see that the constraint itself raises satellite questions of degree and interpretation.

Knowledge

A further uncertainty concerns the definition of ‘knowledge’ itself. Traditionally scientific advances are put forward as hypotheses rather than assertions. What is the standard of proof (or level of comfort) required before an idea can fairly be described as knowledge capable of being part of ‘the state of . . . knowledge’? Is the idea itself a sufficient element of knowledge or must the controversy be resolved in its favour? This is clearly important: the controversial suggestion that the measles mumps rubella (MMR) vaccine may have a causal role in the development of autistic symptoms was first made in the Lancet of 28 February 1998 in these terms ‘We have identified a chronic enterocolitis in children that may be related to neuropsychiatric dysfunction.’80 This suggestion was and is still hotly disputed. It is uncertain whether such a statement is sufficiently robust to qualify as (the most advanced) knowledge.

A related dilemma is the question whether an idea must be complete before it is capable of comprising knowledge. If not, the elements which, if connected together, would have constituted the knowledge will

themselves, very likely at a far earlier date, defeat the availability of the defence. The Court of Justice did not engage with these problems save to the extent that it decided that the knowledge concerned must be the most advanced. Again, the reason for this was likely to have been the basis for the case – Infringement Proceedings – so that the Court was not inclined to make a judgment on what would and would not have been in issue on a fact-based reference for the interpretation of any of these concepts.

When does a researcher’s idea become knowledge? To what extent can the claimant argue that the conjunction of different strands of thought adds up to discoverability? How does this dilemma interact with the provisions of Article 6.2?81 As Stapleton argued (before the Court of Justice had given prominence to the concept of accessibility): once the criterion for discoverability involves leaps of curiosity or creativity, a succession of value questions are introduced, the inevitable consequence of which is that liability should exist only in respect of defects discoverable by reasonable means, for there is no logical halfway house between absolute undiscoverability (rendering the defence nugatory) and undiscoverability by reasonable means (aping the negligence standard).82

Wide or narrow interpretation

Whilst there is as yet no formal determination of the question whether the wide or narrow interpretation of the defence is correct, the introduction of the criterion of reasonableness into the accessibility of knowledge by the Advocate General has gone a long way to suggest that the defence should be given the wider interpretation.83 Indeed the dictum of the Court of Justice that the accessibility criterion was implicit in the wording of Article 7(e) strengthens this view.84

Conduct of the producer

A further concern relates to the conduct of the producer. The general approach of the court is likely to exclude consideration of the conduct of the producer at the instance of either party. It is to be disregarded for the purposes of ascertainment of defect.85 But it may be taken into account for

81An old car is not defective because a later model incorporates air cushions. But how far do the familiar notions of the softness of a balloon, rapid deceleration on impact and the capacity of hard surfaces to cause wounding combine to make the absence of preventive measures a discoverable defect?

the purpose of Article 7(e).86 In the circumstances the remark of Burton J: ‘Negligence, fault and the conduct of the producer or designer can be left to the (limited) ambit of Article 7(e)’ raised but did not solve the problem.87 That is not surprising since the context in which the remark was made was whether the defect had to be discoverable in the individual product. It may be that he intended to convey no more than that the defence is the escape route for the producer ‘who has done all he could reasonably be expected to do (and more)’.88

Exclusion of the producer’s conduct from the question of discoverability would, however, allow the producer to fail to take steps to ascertain the true incidence of the unwanted effects of its products with impunity.89 In the Hepatitis C case the defendants unsuccessfully submitted that they must be given the opportunity to do all they could to avoid injury.90 Defendants would presumably argue that they are liable to perform the requirements of the regulator and any criticism that they had not gone far enough should be made in negligence. What is not resolved is whether a court should decide whether a defect would have been discoverable, for example by the producer taking certain steps.

In the English oral contraceptive litigation, the Committee on Safety of Medicines issued a safety warning relating to the third-generation product in October 1995 after three research reports suggested a significant increase in the incidence of venous thrombo-embolism (VTE) in women using them compared to the incidence in those using second-generation products. Since many of those affected had been exposed to the alleged defect before suspension of the licences, the claimants sought to argue that the defendants could and should have set up post-marketing surveillance studies forthwith upon placing the products on the market. If they had done so, the argument ran, the existence of the defect would have been discoverable far earlier. The defendants relied on the argument that the defence asked only whether (that is, when) the defect had been discoverable and they had been under no obligation relevant to the questions posed by the Directive to take steps to collect, analyse and publish the data. They accepted their obligations under the regulatory regime but no more.
