HEADNOTE
[This headnote is not to be read as part of the judgment]
The respondent suffered an injury to his lower back in consequence of a motor vehicle accident which occurred on 30 November 2016 and for which the appellant admitted liability. It was agreed that this injury consisted in the aggravation of existing degenerative changes. The respondent also claimed that he suffered psychiatric injury as a result of the accident.
The primary judge found that the physical restrictions attributable to the accident subsided within a year of the accident, but that the respondent continued to suffer from a psychiatric injury - an "adjustment disorder" - which was the result of the appellant's negligence.
In the award of damages, the primary judge included sums for past loss of earnings and for past out-of-pocket expenses after November 2017 (that is, after the physical restrictions attributable to the accident subsided), as well as sums for future loss of earnings, future medical expenses and future lawn mowing expenses.
On appeal, the appellant contended that the primary judge erred in finding that, after November 2017, the psychiatric injury was causally related to the accident, because the medical expert evidence established that the adjustment disorder was "secondary to" the pain caused by the physical injury.
The respondent sought by cross-appeal to challenge the finding that the physical restrictions attributable to the accident subsided within a year of the accident. The respondent contended that, because the injury consisted in the aggravation of existing degenerative changes, the onus was on the appellant to provide evidence to explain how and when the symptoms ceased to be related to the accident.
The Court held, dismissing the cross-appeal (per White JA, McCallum JA and Emmett AJA agreeing), and upholding the appeal (per White JA, Emmett AJA agreeing, McCallum JA dissenting):
In relation to the appeal:
Per White JA (Emmett AJA agreeing): having found that the respondent's mental harm was associated with his continuing pain and restriction, but that such pain and restriction was no longer attributable to the subject accident, the primary judge erred in failing to find that the appellant's ongoing psychological symptoms were not causally related to the accident: [57].
Per White JA, obiter: section 32 of the Civil Liability Act 2002 (NSW) applies to both pure mental harm and consequential mental harm: [13]-[15].
Per McCallum JA, contra: there was an absence of definitive and precise evidence to discharge the appellant's onus to exclude the operation of the accident as a contributory cause of the ongoing psychiatric condition: [79]-[80].
In relation to the cross-appeal:
Per White JA (McCallum JA and Emmett AJA agreeing): the evidence that any trauma caused by the accident would have resolved within 12 months was sufficiently precise and definite to displace the inference that the respondent's pain after November 2017 was caused by the accident: [32].
Watts v Rake (1960) 108 CLR 158; [1960] HCA 58 and Purkess v Crittenden (1965) 114 CLR 164; [1965] HCA 34, applied.
Per White JA (McCallum JA and Emmett AJA agreeing): the primary judge was accordingly justified in finding that the respondent's ongoing pain was explicable as the result of his degenerative condition: [38].
