Commission v United Kingdom Case C-300/95 [1997] ECR I-2649
Facts
The European Commission challenged the United Kingdom's implementation of the development-risks defence in the Product Liability Directive. Article 7(e) referred to scientific and technical knowledge when a product entered circulation. Section 4(1)(e) of the Consumer Protection Act 1987 instead referred to what a producer of goods of the same description might be expected to discover. The Commission argued that the UK wording introduced a more lenient, subjective standard. The United Kingdom maintained that the provision could be interpreted objectively and consistently with the directive. The proceedings concerned implementation, rather than liability for one particular defective product.
Legal Issue
Had the Commission established that the UK development-risks defence was incompatible with the directive, and what knowledge standard did the EU defence require?
Held
The Court dismissed the Commission's application. The defence referred to the objective state of scientific and technical knowledge, including the most advanced level, rather than the particular producer's actual knowledge or ordinary industry practice. The relevant knowledge also had to be accessible when the product entered circulation. However, the Commission had not proved that the UK wording, read in its legal context, necessarily failed to secure that result. It identified no inconsistent national judicial decision. Advocate General Tesauro had likewise recommended dismissal, but his opinion was advisory and distinct from the Court's judgment. The outcome did not endorse a subjective reasonable-producer defence or immunise every future application of the Act.
⭐ Legal Principle
Under the directive's development-risks defence, the producer must establish that accessible scientific and technical knowledge at the relevant time could not reveal the defect. The standard is objective. Differences between national and directive wording do not alone prove defective implementation when consistent interpretation remains available.
Significance
The case is important for separating a strict-liability defence from negligence. Ordinary care or ignorance is not enough: the inquiry concerns the accessible state of knowledge. It also illustrates the Commission's burden in infringement proceedings and the need to distinguish an Advocate General's opinion from a judgment. Later EU product-liability legislation has its own transitional rules; the UK statutory position must be analysed independently rather than assuming that every subsequent EU directive automatically changes it.
Common exam questions about this case
Is the producer's personal ignorance a development-risks defence?
Not by itself. The Court described an objective standard encompassing the most advanced accessible scientific and technical knowledge at the relevant time. A producer cannot establish the defence merely by showing that it acted carefully or did not personally know of the defect. Accessibility remains part of the inquiry, rather than unlimited knowledge in the abstract.
Did dismissal prove that every interpretation of section 4(1)(e) was correct?
No. The Commission failed to establish the incompatibility alleged in those proceedings. The Court considered the wording in its legal context and noted the absence of a national decision applying it inconsistently. That does not approve every conceivable future construction or convert the defence into an assessment of the individual manufacturer's reasonable care.
What authority should be given to Advocate General Tesauro's opinion?
It is an advisory opinion offering legal analysis and a proposed outcome, not the Court's binding judgment. Here both supported dismissal, but their roles must remain distinct. An answer should attribute a proposition to the judgment when the Court adopted it, and identify separately any reasoning drawn only from the Advocate General.
