Chambers v Excel Logistics Ltd

Where an accident accelerates disability arising from a pre-existing degenerative condition, loss-of-earnings damages must reflect the difference between the claimant’s actual position and the position that would have existed without the accident. The court must identify the period and extent of loss attributable to the acceleration, while allowing for appropriate credits, deductions and mitigation issues. Materially ambiguous or inconsistent expert evidence about the acceleration must be clarified at or before trial. Where the assessment depends on an interpretation open to doubt, the appellate court should set aside the assessment and order a new trial rather than resolve the factual medical issue itself.

Kevin Philip Chambers appealed against the County Court’s assessment of his loss-of-earnings claim at £1,250 following two accidents at work. Liability was admitted, and general damages were assessed at £6,000. Medical evidence indicated that the accidents had accelerated the onset of disability caused by pre-existing disc degeneration by approximately three years.

The appeal concerned the interpretation and application of that evidence. The appellant claimed substantial further earnings loss following his medical retirement; Excel denied any entitlement beyond a limited period. The central issue was whether the acceleration postponed the disabling condition for a further three years and how the resulting loss should be assessed.

1. Appeal allowed. The County Court’s order assessing loss of earnings at £1,250 was set aside. A new trial was ordered, limited to assessing the loss-of-earnings claim. Excel’s application for permission to appeal the £1,250 assessment was refused.
2. The medical evidence was materially unclear. It referred both to a three-year acceleration and to the possibility that, without the accidents, the claimant would have reached the same condition by the end of 2004 or beginning of 2005. The latter interpretation appeared inconsistent with the earlier reference to acceleration, and the correctness of the judge’s interpretation was open to doubt.
3. In assessing loss caused by acceleration, the court must compare the claimant’s actual position with the position that would have existed without the accidents. It must determine the period during which the acceleration caused loss and assess the resulting earnings difference. The assessment must also address any appropriate credits, deductions or allowances, including matters relating to mitigation and other contributory factors.
4. Where expert evidence central to that assessment is ambiguous, it should be clarified at or before the hearing, preferably by further evidence or oral clarification. The Court of Appeal should not itself resolve the necessary factual interpretation where the evidence requires clarification. The issue was therefore remitted for a fresh assessment.

• Court of Appeal (Civil Division) — [2006] EWCA Civ 1031: allowed the appeal, set aside the loss-of-earnings assessment and ordered a new trial on that claim.
• Clerkenwell County Court — HHJ Hamilton: awarded £6,000 general damages and assessed past and future loss of earnings at £1,250.
