Chester v Afshar: HL 14 Oct 2004

The claimant suffered back pain for which she required neurosurgery. The operation was associated with a 1-2% risk of the cauda equina syndrome, of which she was not warned. She went ahead with the surgery, and suffered that complication. The evidence established that cauda equina syndrome was a random and inherent risk of the surgery, which would have been the same whenever and at whoever’s hand she had the operation. It was also established that she would have had the operation at some point in time, regardless of whether she was warned of the risk. The judge had not found that she would not have had the operation at that time if told. The doctor now appealed.
Held: The appeal failed. The claimant had established causation. The ‘but for’ test was satisfied, because she would not have had the operation when she had it if the appropriate warning had been given and on the probabilities the complication would not have arisen on another occasion The issue went as to causation. A surgeon owes a legal duty to a patient to warn him or her in general terms of possible serious risks involved in the procedure. Her right of autonomy and dignity can and ought to be vindicated by a narrow and modest departure from traditional causation principles. The doctor was liable (Bingham and Hoffmann dissenting).
Lord Hope of Craighead said: ‘To leave the patient who would find the decision difficult without a remedy, as the normal approach to causation would indicate, would render the duty useless in the cases where it may be needed most. This would discriminate against those who cannot honestly say that they would have declined the operation once and for all if they had been warned. I would find that result unacceptable. The function of the law is to enable rights to be vindicated and to provide remedies when duties have been breached. Unless this is done the duty is a hollow one, stripped of all practical force and devoid of all content. It will have lost its ability to protect the patient and thus to fulfil the only purpose which brought it into existence. On policy grounds therefore I would hold that the test of causation is satisfied in this case. The injury was intimately involved with the duty to warn. The duty was owed by the doctor who performed the surgery that Miss Chester consented to. It was the product of the very risk that she should have been warned about when she gave her consent. So I would hold that it can be regarded as having been caused, in the legal sense, by the breach of that duty. . . I would hold that justice requires that Miss Chester be afforded the remedy which she seeks, as the injury which she suffered at the hands of Mr Afshar was within the scope of the very risk which he should have warned her about when he was obtaining her consent to the operation which resulted in that injury.
Lord Woolf said: ‘In a case where it is being alleged that a plaintiff has been deprived of the opportunity to make a proper decision as to what course he or she should take in relation to treatment, it seems to me to be the law, as indicated in the cases to which I have just referred, that if there is a significant risk which would affect the judgment of a reasonable patient, then in the normal course it is the responsibility of a doctor to inform the patient of that significant risk, if the information is needed so that the patient can determine for him or herself as to what course he or she should adopt. ‘
