15 The Civil Liability Act 2002 does not apply to the respondent's claims (see s 3B(1)(b) of that Act). Accordingly, the common law applies. It is trite that the common law recognises claims for mental trauma, not involving a recognised psychiatric injury, when the mental trauma is associated with physical harm caused by the negligence of the defendant; see, for example, CSR Ltd v Thompson (2003) NSWCA 329; (2003) 59 NSWLR 77 at [41]. The respondent in the present case suffered physical harm of a most severe kind.
16 An example of the common law is Kralj v McGrath [1986] 1 All ER 54 where Woolf J was concerned with a claim by a mother against an obstetrician who had attempted to deliver the mother's child by treatment described as "horrific and wholly unacceptable". The child was born with severe disabilities caused by the obstetrician's treatment and died eight weeks after birth. Woolf J (at 61), after observing that "it would be wholly inappropriate to introduce into claims of this sort, for breach of contract and negligence, the concept of aggravated damages", said:
"I do, however, accept that the effect on a mother who during the course of her labour undergoes unnecessary suffering may be greater if this results not in the birth of a normal child but a child who is in the unfortunate condition that Daniel was here. It would be easier for a mother to forget or adjust to the consequences of that distressing experience if she has the comfort of a normal child. If instead of having the satisfaction of the birth of a normal child she has the distress of the knowledge that this child is disabled, subject to the disabilities that Daniel was, it would be more difficult for her to overcome the consequences and the unnecessary suffering may have a greater impact on her.
What I am saying is no more than that what the court has to do is to judge the effect on the particular plaintiff of what happened to her. If the situation is one where the consequences are such that she feels able to make light of what has happened, then her loss is less than it will be where the situation is one where the impact of what has happened is accentuated because of the additional stress which the mother is undergoing at that time."
17 The reasoning expressed in Kralj v McGrath is, with respect, unexceptionable and reflects the law in Australia: See Hunter Area Health Services v Marchlewski [2000] NSWCA 294; (2000) 51 NSWLR 268 at [100] to [104] per Mason P (with whom Stein JA and Heydon JA agreed.)
18 In AB v South West Water Services Ltd [1993] QB 507 the English Court of Appeal struck out a claim for aggravated damages based on indignation at the defendant's conduct following a negligently committed public nuisance. The Court approved and followed Kralj v McGrath. Sir Thomas Bingham MR said (at 532-533):
"I turn, lastly, to the claim ... for aggravated damages. The plaintiffs are of course entitled to be fully compensated for all they suffered as a direct result of the defendants' admitted breach of duty. The ordinary measure of compensatory damages will cover all they have suffered as a result of that breach, physically, psychologically and mentally. Full account will be taken of the distress and anxiety which such an event necessarily causes. To the extent that any of these effects was magnified or exacerbated by the defendants' conduct, the ordinary measure of damages will compensate. The question is whether, in addition to that full compensatory measure, the plaintiffs have pleaded a sustainable claim for additional compensation by way of aggravated damages. This is claimed in paragraph 27 on the basis that the plaintiffs' feelings of indignation were aroused by the defendants' high-handed way of dealing with the incident. I know of no precedent for awarding damages for indignation aroused by a defendant's conduct. Defamation cases in which a plaintiff's damages are increased by the defendant's conduct of the litigation (as by aggressive cross-examination of the plaintiff or persistence in a groundless plea of justification) are not in my view a true exception, since injury to the plaintiff's feelings and self-esteem is an important part of the damage for which compensation is awarded. In very many other tort actions (and, for that matter, actions in contract, boundary disputes, partnership actions and other disputes) the plaintiff is indignant at the conduct of the defendant (or his insurers). An award of damages does not follow: Nor, in my judgment should it, since this is not damage directly caused by the defendant's tortious conduct and this is not damage which the law has ever recognised."
