Allen v British Rail Engineering Ltd

An employer whose tortious conduct materially contributes to an employee’s cumulative injury is liable, but damages are generally limited to the injury attributable to that conduct. The court should make the best apportionment permitted by the evidence. Scientific uncertainty and an inability to quantify the contribution precisely do not justify either denying recovery or imposing liability for harm caused innocently.

The required evidential inquiry must remain proportionate to the value of the claim and the uncertainties inherent in personal injury assessment. For limitation purposes, knowledge of a general connection between symptoms and work does not necessarily amount to knowledge of their connection with the relevant workplace process. When considering disapplication of the primary period, the court may assess the claimant’s reasons and blameworthiness, actual evidential prejudice, and the wider litigation context.

The claimant developed vibratory white finger through prolonged use of vibrating tools while employed by British Rail Engineering Ltd. The employer’s breach began only after the claimant had already sustained some damage. Mrs Justice Smith held that proper precautions would have reduced, but not eliminated, his later exposure. She awarded £4,000 after attributing part of the injury to non-tortious exposure.

The claimant appealed against that apportionment. The employer cross-appealed against the judge’s use of section 33 of the Limitation Act 1980 to permit the otherwise time-barred claims of the claimant and another test claimant, Mr Gardiner, to proceed. The central questions were whether material contribution made the employer liable for the whole cumulative injury, whether the judge could estimate its contribution at 50%, and whether her limitation decisions were permissible.

1. Appeal and cross-appeal dismissed. Schiemann LJ delivered the judgment of the Court, comprising Schiemann, May and Latham LJJ.

2. An employee establishes liability by proving that the employer’s tortious conduct made a material contribution to the disability. That rule does not ordinarily make the employer liable for damage which its tort did not cause. Subject to cases in which separate tortfeasors may each properly be treated as causing the whole indivisible harm, liability is limited to the extent of the employer’s contribution.

3. The court must make the best apportionment available on the evidence. It should not deny relief merely because the claimant cannot demonstrate the precise proportion attributable to the tort. The required accuracy depends on the accuracy reasonably possible, the other uncertainties in assessing personal injury damages, and the amount at stake. This approach followed the reasoning in Thompson v Smiths Ship Repairers (North Shields) Ltd [1984] QB 405 and Holtby v Brigham & Cowan (Hull) Ltd [2000] 3 All ER 421. Bonnington Castings Ltd v Wardlaw [1956] AC 613 established material contribution but had not addressed apportionment.

4. The trial judge was entitled to use a broad-brush assessment. The evidence supported her findings that compliant conduct would have reduced rather than eliminated the claimant’s exposure, and that he would probably have continued using vibrating tools at a lower intensity. Her 50% assessment avoided the greater injustice of either awarding nothing for want of precise proof or making the employer pay for non-negligent harm. Reopening or remitting the modest claim for further evidence would have been disproportionate.

5. For sections 11 and 14 of the Limitation Act 1980, the relevant knowledge concerned the connection between the condition and vibrating machinery. A vague belief that symptoms might relate to work was insufficient. Given the gradual nature of the condition, the judge could find that the claimants neither knew nor ought earlier to have known of the necessary connection.

6. The judge also permissibly exercised the discretion under section 33. The short delay caused no demonstrated loss of cogent evidence. A claimant’s reasons for delay and lack of blameworthiness were relevant, as were the employer’s prior knowledge, the absence of actual prejudice, and the context of extensive test-case litigation. The section 33 decisions for both claimants therefore stood.

1. Court of Appeal: The claimant’s appeal against the apportionment of damages and the employer’s cross-appeal on limitation were dismissed. Permission to appeal to the House of Lords was refused.
2. High Court: Mrs Justice Smith found the employer liable, apportioned the claimant’s general damages to £4,000, and exercised section 33 of the Limitation Act 1980 so that the otherwise time-barred claims of Mr Allen and Mr Gardiner could proceed. No citation for that judgment is stated.
