(High Court of Australia) Mason J: ‘In deciding whether there has been a breach of the duty of care the tribunal of fact must first ask itself whether a reasonable man in the defendant’s position would have foreseen that his conduct involved a risk of injury to the plaintiff or to a class of persons including the plaintiff. If the answer be in the affirmative, it is then for the tribunal of fact to determine what a reasonable man would do by way of response to the risk. The perception of the reasonable man’s response calls for a consideration of the magnitude of the risk and the degree of probability of its occurrence, along with the expense, difficulty and inconvenience of taking alleviating action and any other conflicting responsibilities which the defendant may have. It is only when these matters are balanced out that the tribunal of fact can confidently assert what is the standard of response to be ascribed to the reasonable man placed in the defendant’s position. The considerations to which I have referred indicate that a risk of injury which is remote in the sense that it is extremely unlikely to occur may nevertheless constitute a foreseeable risk. A risk which is not far-fetched or fanciful is real and therefore foreseeable. But, as we have seen, the existence of a foreseeable risk of injury does not of itself dispose of the question of breach of duty. The magnitude of the risk and its degree of probability remain to be considered with other relevant factors.’
Held: ‘Lying at the heart of this matter, however, is the necessity to ensure, as far as possible, that consumers are not unnecessarily or, through no fault of their own, unknowingly exposed to the risk of injury or other adverse consequences being suffered by reason of their use of products available to them in the marketplace.’ and ‘As a general proposition it appears to me to be obvious that where possible consequences of the contraction of a condition include death, even though the risk of any contraction may be very small, a potential purchaser is, at least, entitled to know of the existence of that risk and to be able to choose whether or not it will be accepted.’
