LORD KERR AND LORD REED: (with whom Lord Neuberger, Lord Clarke, Lord Wilson and Lord Hodge agree)
"since I felt the risk of her baby having a significant enough shoulder dystocia to cause even a nerve palsy or severe hypoxic damage to the baby was low I didn't raise it with her, and had I raised it with her then yes, she would have no doubt requested a caesarean section, as would any diabetic today."
"And if Dr McLellan had said your baby appears to be on the 95th centile or whatever, so it's borderline large, it's the top end of the normal size, its largish … We know that you are diabetic. We know you are whatever height you are, we've estimated the size as best we can all the way through, there are risks but I don't think the baby is so big that vaginal delivery is beyond you and I think we should try for vaginal delivery and if anything comes up we will go to caesarean section. Now if that was the general tenor of the discussion, could you criticise that? I know it's very vague and it's very difficult because it's another hypothesis, Mr Stewart and I appreciate that but yes I would ... are you able to answer that question?"
The judgments of the courts below
"A case which is based on an allegation that a fully considered decision of two consultants in the field of their special skill was negligent clearly presents certain difficulties of proof. It is not enough to show that there is a body of competent professional opinion which considers that theirs was a wrong decision, if there also exists a body of professional opinion, equally competent, which supports the decision as reasonable in the circumstances. It is not enough to show that subsequent events show that the operation need never have been performed, if at the time the decision to operate was taken it was reasonable in the sense that a responsible body of medical opinion would have accepted it as proper."
"The merit of the Bolam test is that the criterion of the duty of care owed by a doctor to his patient is whether he has acted in accordance with a practice accepted as proper by a body of responsible and skilled medical opinion …. To decide what risks the existence of which a patient should be voluntarily warned and the terms in which such warning, if any, should be given, having regard to the effect that the warning may have, is as much an exercise of professional skill and judgment as any other part of the doctor's comprehensive duty of care to the individual patient, and expert medical evidence on this matter should be treated in just the same way. The Bolam test should be applied." (pp 893, 895)
"But when it comes to warning about risks, the kind of training and experience that a judge will have undergone at the Bar makes it natural for him to say (correctly) it is my right to decide whether any particular thing is done to my body, and I want to be fully informed of any risks there may be involved of which I am not already aware from my general knowledge as a highly educated man of experience, so that I may form my own judgment as to whether to refuse the advised treatment or not.
No doubt if the patient in fact manifested this attitude by means of questioning, the doctor would tell him whatever it was the patient wanted to know ..." (p 895)
There was on the other hand no obligation to provide patients with unsolicited information about risks:
"The only effect that mention of risks can have on the patient's mind, if it has any at all, can be in the direction of deterring the patient from undergoing the treatment which in the expert opinion of the doctor it is in the patient's interest to undergo." (p 895)
"If, therefore, the failure to warn a patient of the risks inherent in the operation which is recommended does constitute a failure to respect the patient's right to make his own decision, I can see no reason in principle why, if the risk materialises and injury or damage is caused, the law should not recognise and enforce a right in the patient to compensation by way of damages." (pp 884-885)
"The doctor's concern is with health and the relief of pain. These are the medical objectives. But a patient may well have in mind circumstances, objectives, and values which he may reasonably not make known to the doctor but which may lead him to a different decision from that suggested by a purely medical opinion." (pp 885-886)
"To the extent that I have indicated I think that English law must recognise a duty of the doctor to warn his patient of risk inherent in the treatment which he is proposing: and especially so, if the treatment be surgery. The critical limitation is that the duty is confined to material risk. The test of materiality is whether in the circumstances of the particular case the court is satisfied that a reasonable person in the patient's position would be likely to attach significance to the risk. Even if the risk be material, the doctor will not be liable if upon a reasonable assessment of his patient's condition he takes the view that a warning would be detrimental to his patient's health."
"But even in a case where, as here, no expert witness in the relevant medical field condemns the non-disclosure as being in conflict with accepted and responsible medical practice, I am of opinion that the judge might in certain circumstances come to the conclusion that disclosure of a particular risk was so obviously necessary to an informed choice on the part of the patient that no reasonably prudent medical man would fail to make it. The kind of case I have in mind would be an operation involving a substantial risk of grave adverse consequences, as, for example, the ten per cent risk of a stroke from the operation which was the subject of the Canadian case of Reibl v Hughes, 114 DLR (3d) 1. In such a case, in the absence of some cogent clinical reason why the patient should not be informed, a doctor, recognising and respecting his patient's right of decision, could hardly fail to appreciate the necessity for an appropriate warning." (p 900)
"I should perhaps add at this point, although the issue does not strictly arise in this appeal, that, when questioned specifically by a patient of apparently sound mind about risks involved in a particular treatment proposed, the doctor's duty must, in my opinion, be to answer both truthfully and as fully as the questioner requires."
The subsequent case law
"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."
"Lord Woolf's formulation refines Lord Bridge's test by recognising that what is substantial and what is grave are questions on which the doctor's and the patient's perception may differ, and in relation to which the doctor must therefore have regard to what may be the patient's perception. To the doctor, a chance in a hundred that the patient's chickenpox may produce an abnormality in the foetus may well be an insubstantial chance, and an abnormality may in any case not be grave. To the patient, a new risk which (as I read the judge's appraisal of the expert evidence) doubles, or at least enhances, the background risk of a potentially catastrophic abnormality may well be both substantial and grave, or at least sufficiently real for her to want to make an informed decision about it." (para 16)
"Whether a medical practitioner carries out a particular form of treatment in accordance with the appropriate standard of care is a question in the resolution of which responsible professional opinion will have an influential, often a decisive, role to play; whether the patient has been given all the relevant information to choose between undergoing and not undergoing the treatment is a question of a different order. Generally speaking, it is not a question the answer to which depends upon medical standards or practices. Except in those cases where there is a particular danger that the provision of all relevant information will harm an unusually nervous, disturbed or volatile patient, no special medical skill is involved in disclosing the information, including the risks attending the proposed treatment." (pp 489-490: original emphasis)
"a risk is material if, in the circumstances of the particular case, a reasonable person in the patient's position, if warned of the risk, would be likely to attach significance to it or if the medical practitioner is or should reasonably be aware that the particular patient, if warned of the risk, would be likely to attach significance to it." (p 490)
Conclusions on the duty of disclosure
"Work in partnership with patients. Listen to, and respond to, their concerns and preferences. Give patients the information they want or need in a way they can understand. Respect patients' right to reach decisions with you about their treatment and care."
"The doctor explains the options to the patient, setting out the potential benefits, risks, burdens and side effects of each option, including the option to have no treatment. The doctor may recommend a particular option which they believe to be best for the patient, but they must not put pressure on the patient to accept their advice. The patient weighs up the potential benefits, risks and burdens of the various options as well as any non-clinical issues that are relevant to them. The patient decides whether to accept any of the options and, if so, which one." (para 5)
In relation to risks, in particular, the document advises that the doctor must tell patients if treatment might result in a serious adverse outcome, even if the risk is very small, and should also tell patients about less serious complications if they occur frequently (para 32). The submissions on behalf of the General Medical Council acknowledged, in relation to these documents, that an approach based upon the informed involvement of patients in their treatment, rather than their being passive and potentially reluctant recipients, can have therapeutic benefits, and is regarded as an integral aspect of professionalism in treatment.
The disclosure of risks in the present case
"in the absence of some other identifiable error, such as (without attempting an exhaustive account) a material error of law, or the making of a critical finding of fact which has no basis in the evidence, or a demonstrable misunderstanding of relevant evidence, or a demonstrable failure to consider relevant evidence, an appellate court will interfere with the findings of fact made by a trial judge only if it is satisfied that his decision cannot reasonably be explained or justified."
It is in addition only in comparatively rare cases that this court interferes with concurrent findings of fact by lower courts. As Lord Jauncey of Tullichettle explained in Higgins v J & C M Smith (Whiteinch) Ltd 1990 SC (HL) 63, 82:
"Where there are concurrent findings of fact in the courts below generally this House will interfere with those findings only where it can be shown that both courts were clearly wrong."
"I have already said that the real risk of grave consequences arising should shoulder dystocia occur were very small indeed. Given the very small risks the first question must be for the court: has the pursuer established on the basis of the 'but for' test, a link between the failure to advise her of said risks and damage to the child. Or to put the matter another way, has the pursuer established that had she been advised of the said risks she would have chosen a caesarean section and thus avoided the damage to the child?" (emphasis supplied)
"There can be a high perinatal mortality and morbidity associated with the condition, even when it is managed appropriately. Maternal morbidity is also increased, particularly postpartum haemorrhage (11%) and fourth-degree perineal tears (3.8%), and their incidence remains unchanged by the manoeuvres required to effect delivery."
No-one suggests that this was not equally well known in 1999. The risk of permanent injury to the baby is less than the risk of injury to the mother, but it includes a very small risk of catastrophic injury resulting from the deprivation of oxygen during delivery, as occurred in this case.
