(iv) causation in the sense that the breach of duty to the plaintiff caused her damage.
15 Mr Segal submitted that the defendant owed to the mother of the plaintiff as his patient a duty to inform the mother of her rubella status and to give her advice as to the risk of her infection passing to the child. Mr Segal submitted further that the doctor owed the plaintiff a duty with exactly the same content. Any decision then to be taken was to be the decision of the mother, not the doctor. Mr Segal submitted this was where the analysis in McKay & Anor v Essex Area Health Authority & Anor (supra) went astray because in McKay the duty identified and rejected was a duty to terminate the pregnancy. I shall return to this criticism of McKay shortly. Mr Segal submitted that mother and child were "a unity in duality" during the pregnancy, and that the mother was to be regarded as acting as agent for the baby. Mr Garling, on the other hand, submitted that it was unacceptable for the law to recognise such concurrent duties owed by a doctor to a mother and her unborn child when the discharge of the duty owed to the mother might influence a decision of the mother adverse to the unborn child. In any event Mr Garling submitted that the only duty to the plaintiff which the law recognised in the circumstances was a duty not to harm the plaintiff.
16 I consider that Mr Garling's submission is correct. The authorities reviewed in Edwards (para 54-60) establish that a duty of care can be owed to an unborn child: Watt v Rama (1972) VR 353; Burton v Islington Health Authority; De Martell v Merton & Sutton Health Authority (1992) 3 All ER 833. Moreover that duty of care may be owed to a child not conceived at the time of the negligent act, provided the child was within the class to whom the duty was owed: X & Y (by her tutor X) v Pal & Ors (1991) 23 NSWLR 26 (see in particular the judgment of Clarke JA at 38-42).
17 However, those authorities do not support the proposition that there is owed to an unborn child a duty with the content for which Mr Segal contends. In Watt v Rama (supra) and Burton v Islington Health Authority; De Martell v Merton & Sutton Health Authority (supra) the tort feasors caused harm to the unborn child by negligent acts, and in X & Y v Pal (supra) the unborn child was harmed when there was a failure to detect syphilis in the mother and then to treat that condition. Not only do those decisions not assist the plaintiff as to the content of the duty owed, but the decision in McKay is directly against the plaintiff. As I observed in Edwards (at paras 60-61):
"In McKay the duty in the relevant authority's laboratory and in the doctor was defined by Stephenson LJ as being a duty not to injure the child during the mother's pregnancy (at 1178-79). Ackner LJ (at 1188) rejected the submission that the duty of care to the foetus, albeit indirectly by advice to the mother, was to cause its death, and said:
'I cannot accept that the common law duty of care to a person can involve, without specific legislation to achieve this end, the legal obligation to that person whether or not in utero to terminate his existence. Such a proposition runs wholly contrary to the concept of sanctity of human life.'
Griffiths LJ said (at 1192):
'It surely cannot be asserted that the doctor owes a duty to the foetus to urge its destruction.'"
18 I return at this point to Mr Segal's criticism of McKay, to the effect that the Court of Appeal wrongly characterised the content of the duty which it was claimed was owed to the unborn child, because the unborn child was not asserting a duty to be killed but merely a duty that the mother be given appropriate advice, thus putting the mother in a position to make an informed decision whether or not to continue with her pregnancy.
19 As I understand McKay, there was no such error made in considering the content of the duty proposed. Stephenson LJ considered the duty contended for and considered where that led (at pp 1178-1179):
"If, as is conceded, any duty is owed to an unborn child, the authority's hospital laboratory and the doctor looking after the mother during her pregnancy undoubtedly owed the child a duty not to injure it, and if she had been injured as a result of lack of reasonable care and skill on their part after birth, she could have sued them, as she is suing the doctor, for damages to compensate her for the injury they had caused her in the womb. Compare the thalidomide cases, where it was assumed that such as action might lie: eg, Distillers Co. (Biochemicals) Ltd v Thompson [1971] AC 458. But this child has not been injured by either defendant, but by the rubella which has infected the mother without fault on anybody's part. Her right not to be injured before birth by the carelessness of others has not been infringed by either defendant, any more than it would have been if she had been disabled by disease after birth. Neither defendant has broken any duty to take reasonable care not to injure her. The only right on which she can rely as having been infringed is a right not to be born deformed or disabled, which means, for a child deformed or disabled before birth by nature or disease, a right to be aborted or killed; or, if that last plain word is thought dangerously emotive, deprived of the opportunity to live after being delivered from the body of her mother. The only duty which either defendant can owe to the unborn child infected with disabling rubella is a duty to abort or kill her or deprive her of that opportunity.
It is said that the duty does not go as far as that, but only as far as a duty to give the mother an opportunity to choose her abortion and death. That is true as far as it goes. The doctor's alleged negligence is in misleading the mother as to the advisability of an abortion, failing to inform or advise her of its advisability or desirability; the laboratory's alleged negligence is not so pleaded in terms but the negligence pleaded against them in failing to make or interpret the tests of the mother's blood samples or to inform the doctor of their results must, like the doctor's negligence, be a breach of their duty to give the doctor an opportunity to advise the mother of the risks in continuing to let the foetus live in the womb and be born alive. But the complaint of the child, as of the mother, against the authority, as against the doctor, is that their negligence burdened her (and her mother) with her injuries. That is another way of saying that the defendants' breaches of their duties resulted, not just in the child's being born but in her being born injured or, as the judge put it, with deformities. But as the injuries or deformities were not the result of any act or omission of the defendants, the only result for which they were responsible was her being born. For that they were responsible because if they had exercised due care the mother would have known that the child might be born injured or deformed, and the plaintiffs' pleaded case is that, if the mother had known that, she would have been willing to undergo an abortion, which must mean she would have undergone one or she could not claim that the defendants were responsible for burdening her with an injured child. If she would not have undergone an abortion had she known the risk of the child being born injured, any negligence on the defendants' part could not give either plaintiff a cause of action in respect of the child being born injured.
I am accordingly of opinion that though the judge was right in saying that the child's complaint is that she was born with deformities, without which she would have suffered no damage and have no complaint, her claim against the defendants is a claim that they were negligent in allowing her, injured as she was in the womb, to be born at all, a claim for 'wrongful entry into life' or 'wrongful life'."
20 Later, Stephenson LJ specifically rejected the proposition that there was a duty to the child to give to the mother of the child advice such as might influence a decision to be taken by her to have an abortion (at 1180-1181):
"I am therefore compelled to hold that neither defendant was under any duty to the child to give the child's mother an opportunity to terminate the child's life. That duty may be owed to the mother, but it cannot be owed to the child.
To impose such a duty towards the child would, in my opinion, make a further inroad on the sanctity of human life which would be contrary to public policy. It would mean regarding the life of a handicapped child as not only less valuable than the life of a normal child, but so much less valuable that it was not worth preserving, and it would even mean that a doctor would be obliged to pay damages to a child infected with rubella before birth who was in fact born with some mercifully trivial abnormality. These are the consequences of the necessary basic assumption that a child has a right to be born whole or not at all, not to be born unless it can be born perfect or 'normal', whatever that may mean.
Added to that objection must be the opening of the courts to claims by children born handicapped against their mothers for not having an abortion. For the reasons given by the Royal Commission on Civil Liability and Compensation for Personal injury (1978) (Cmnd. 7054-1), cited by Ackner LJ, that is, to my mind, a graver objection than the extra burden on doctors already open to actions for negligent treatment of a foetus, which weighed with the Law Commission."
21 Nor do I see in the judgments of Ackner LJ or Griffiths LJ any misconception of what was being submitted was the content of the duty for which the appellant was arguing in McKay. Contrary to Mr Segal's submission, I find the decision in McKay to be most persuasive, and I propose to follow it. Whilst the plaintiff was subsequently born with severe disabilities, I cannot accept, and I do not accept, that the defendant owed to the plaintiff a duty to give such advice to the plaintiff's mother during pregnancy as would or could deprive the plaintiff of the opportunity of life. Consistently with McKay, in my opinion the content of the duty of care owed to the plaintiff was not to injure her, and nothing else. I am fortified in this conclusion by considerations of public policy to which I shall later refer.
22 Was there a breach of the duty of care with the content I have defined? Did the defendant by act or omission cause injury to the plaintiff? Unless these questions are answered in the affirmative, the plaintiff cannot succeed.
23 On this issue of causation I repeat what I wrote in Edwards at para 68:
"Common sense has a central role to play in determining causation. In Stapley v Gypsum Mines Ltd (1953) AC 663 at 681, Lord Reid said that what caused an accident from the point of view of legal liability 'must be determined by applying common sense to the facts of each particular case'. Lord Reid's dicta were cited with approval in March v Stramare (supra) by Mason CJ at 515 and by Deane J at 523-524, and in Chappel v Hart (supra) by Gaudron J at 238. The application of common sense cannot be divorced from value judgments and policy considerations: March v Stramare (at 516) and Chappel v Hart (at 243)."
24 In my opinion, it cannot be said, consistently with the application of settled principles, that the defendant caused injury to the plaintiff either by act or omission, given that the duty of care that existed had the content I have defined. Indeed, Mr Segal's submissions on causation depended upon the acceptance by the court of the broader content of the duty of care for which he contended, and which I have rejected.
25 It is not contended that the defendant was in any way responsible for the plaintiff's mother becoming infected with rubella. Indeed, it is an agreed fact that:
"The plaintiff did not become infected in utero with rubella by reason of any neglect on the part of the defendant."
26 Nor is it suggested that there was any treatment the defendant could have given the plaintiff's mother to protect the plaintiff from the harmful effects of the rubella upon her.
27 With the above in mind, it follows, in my opinion, that there was no breach of that duty of care I have determined was owed by the defendant and the plaintiff's claim must fail.
28 However I propose to consider other issues argued in this case, as I did in Edwards. Should it be assumed, contrary to the conclusions I have reached, that the plaintiff has met the requirements of establishing the content of the duty of care asserted, breach of that duty and a causative link between breach and the disabilities with which the plaintiff was born, it would remain to be determined whether the plaintiff has suffered damage. Without proof of damage an action in tort is not maintainable. It is only if damage is proved that damages may be awarded to compensate a plaintiff.
29 I referred in Edwards to what the High Court said as to the significance of this distinction in Mahony v Kruschich (Demolitions) Pty Limited (1985) 156 CLR 522. I here repeat what was said by Gibbs CJ, Mason, Wilson, Brennan and Dawson JJ at 527:
"In negligence, 'damage' is what the plaintiff suffers as the foreseeable consequence of the tortfeasor's act or omission. Where a tortfeasor's negligent act or omission causes personal injury, 'damage' includes both the injury itself and other foreseeable consequences suffered by the plaintiff. The distinction between 'damage' and 'damages' is significant. Damages are awarded as compensation for each item or aspect of the damage suffered by a plaintiff…"
30 The issue must be addressed as to what was the damage which the plaintiff has suffered.
31 In written submissions Mr Segal acknowledged "the impossibility of assessing general damages by comparing the value of life with disabilities against non existence." He further acknowledged that it was offensive to people with disabilities for a suggestion to be advanced that "non life is preferable to a life with disabilities."
32 Nevertheless, it was submitted that the "damage" suffered by the plaintiff was properly to be categorised as "birth with disabilities". I am unable to accept this submission.
33 In order to find "damage" in the plaintiff's case, it is necessary to make a comparison between non existence and life with disabilities. The plaintiff's case is that she was born in consequence of the defendant's negligence and it has to be remembered that the plaintiff's only opportunity for life was life with the profound disabilities that the plaintiff has been required to endure. Therefore here, as in Edwards, in order to determine whether the plaintiff suffered "damage" in being born with disabilities inevitably involves comparing the value of non existence with the value of existence in a disabled state. Whilst the plaintiff's disabilities are extremely severe, I nevertheless conclude that the comparison required as a matter of legal principle is an impossible exercise.
34 Once again, I state that I have found the reasoning of the Court of Appeal in McKay on this question of "damage" and the assessment of damages to be very persuasive and I refer in particular to the following passages:
