Pure Economic Loss in UK Law

The second is commonly known as the threefold test: whether loss to the claimant was a reasonably foreseeable consequence of what the defendant did or failed to do; whether the relationship between the parties was one of sufficient proximity; and whether in all the circumstances it is fair, just and reasonable to impose a duty of care on the defendant towards the claimant (what Kirby J in Perre v Apand Pty Ltd [1999] HCA 36, (1999) 198 CLR 180, para 259, succinctly labelled "policy").

First, there are cases in which one party can accurately be said to have assumed responsibility for what is said or done to another, the paradigm situation being a relationship having all the indicia of contract save consideration.

Although the categories of cases in which such special relationship can be held to exist are not closed, as yet only two categories have been identified, viz. (1) where there is a fiduciary relationship and (2) where the defendant has voluntarily answered a question or tenders skilled advice or services in circumstances where he knows or ought to know that an identified plaintiff will rely on his answers or advice.

In actions of negligence, when the plaintiff has suffered no damage to his person or property, but has only sustained economic loss the law does not usually permit him to recover that loss. He gave this illustration: When a mine is flooded by negligence, thousands of men may be thrown out of work. So here I would ask: When an electric cable is damaged, many factories may be stopped from working. It is not sensible to saddle losses on this scale on to one sole contractor.

What emerges is that, in addition to the foreseeability of damage, necessary ingredients in any situation giving rise to a duty of care are that there should exist between the party owing the duty and the party to whom it is owed a relationship characterised by the law as one of "proximity" or "neighbourhood" and that the situation should be one in which the court considers it fair, just and reasonable that the law should impose a duty of a given scope upon the one party for the benefit of the other.

Indeed it is difficult to resist a conclusion that what have been treated as three separate requirements are, at least in most cases, in fact merely facets of the same thing, for in some cases the degree of foreseeability is such that it is from that alone that the requisite proximity can be deduced, whilst in others the absence of that essential relationship can most rationally be attributed simply to the court's view that it would not be fair and reasonable to hold the defendant responsible.

The distinction is technical and artificial if not actually suspect in the circumstances of the present case, and is to my mind made irrelevant by the fact that Catherine's conception and birth are the very things that the defenders' professional services were called upon to prevent. In principle any losses occasioned thereby are recoverable however they may be characterised.
