Road Accident Fund v G S O Guedes

The respondent, a magazine editor born on 20 February 1978, sustained bodily injuries (whiplash injury to cervical spine, thoracic sprain, and mild T-7 vertebral compression fracture) in a motor vehicle accident on 12 November 2000. Before the accident, she had never injured her back nor suffered back pain. The appellant (Road Accident Fund) conceded liability for the merits of the claim. After January 2003, the respondent resumed work on a part-time basis (2-3 full days and 2-3 half days per week), experiencing stiffness, painful neck, radiating pain, and headaches lasting up to three days, aggravated by sustained computer work required by her editorial position. Her employer testified she lacked sufficient energy to work adequately despite her natural skills, and had to appoint two additional people to cover portions of her duties. Medical experts indicated her working capacity was severely compromised. The Johannesburg High Court (Boruchowitz J) awarded R3,119,048 for future loss of earning capacity, applying contingency deductions of 10% to the 'but for scenario' (pre-accident earning capacity calculated at R7,954,150) and 30% to the 'having regard to scenario' (post-accident earning capacity calculated at R5,770,981).

• What is the proper approach of an appeal court when reviewing awards for damages for future loss of earning capacity?
• What contingency deductions should be applied in calculating future loss of earning capacity in the 'but for scenario' and 'having regard to scenario'?
• Did the trial court misdirect itself in applying a 10% contingency deduction to the 'but for scenario' for a plaintiff aged 26?
• Was the trial court's assessment that the respondent would have been promoted to the highest level in her field (publisher) justified on the evidence?
• Was the 30% contingency deduction in the 'having regard to scenario' appropriate given the medical evidence?

The appeal was allowed with costs, including costs of two counsel. Paragraph (a)3 of the trial court's order was replaced. The award for future loss of income/earning capacity was reduced from R3,119,048 to R2,323,633, calculated as follows: Value but for accident R7,954,150 less 20% contingency (R1,590,830) = R6,363,320; Value having regard to accident R5,770,981 less 30% contingency (R1,731,294) = R4,039,687; Net loss = R2,323,633.

An appeal court will interfere with a trial court's award of damages for future loss of earning capacity where: (i) there has been an irregularity or misdirection (including consideration of irrelevant facts, ignoring relevant facts, incorrect contingency allowances, or decisions based on inadequate facts); (ii) no sound basis exists for the award; or (iii) there is substantial variation or striking disparity between the trial court's award and what the appeal court considers appropriate. When applying actuarial guidelines such as contingency deduction scales, courts must correctly understand and apply them to the specific circumstances of the plaintiff, including age. A misdirection based on misunderstanding or misapplication of such guidelines entitles an appeal court to substitute the correct contingency deduction. The sliding scale for contingency deductions in 'but for scenarios' decreases with age (approximately 25% for children, 20% for youth, 10% for middle age), and must be applied proportionately to the plaintiff's actual age and circumstances.

The court observed that in specialized fields such as Information Technology publishing, it is not unusual for outstanding or even merely competent young people to make rapid or even meteoric progress in their careers. The court noted the unfortunate singular lack of competence demonstrated by the defendant's attorney in conducting the defence, which increased the burden on the trial judge. The court also noted that the fact that the defendant's attorney did not suggest a particular contingency deduction was wrong does not necessarily mean the appellant consented to such deduction. The court commented that calculation of future loss of earning capacity is inherently speculative, necessarily involves rough estimates, and courts can only make an estimate of present value of future loss. The court observed that it was questionable how much of the respondent's lack of energy, stress and difficulty coping resulted from physical problems versus psychological problems, particularly noting that she experienced virtually no pain while on holiday (though it was unclear whether this was due to reduced stress or absence of computer work).

This case clarifies important principles regarding: (1) the proper application of contingency deductions in actuarial calculations for future loss of earning capacity, emphasizing that general guidelines (such as those in Koch's Quantum Yearbook) must be correctly understood and applied with reference to the specific age and circumstances of the plaintiff; (2) the circumstances in which an appeal court will interfere with a trial court's exercise of discretion in awarding damages for future loss of earning capacity - namely where there has been a misdirection, no sound basis exists for the award, or there is substantial variation/striking disparity; (3) the proper weight to be accorded to uncontested expert evidence regarding both pre-accident career prospects and post-accident functional limitations; and (4) that while courts have wide discretion in assessing damages for future loss of earning capacity, such discretion must be exercised on correct legal principles and proper understanding of actuarial tools and evidence.
