Sadie Briggs v Drylined Homes Limited

In a civil fact-finding exercise, the claimant bears the burden of proving each fact in issue on the balance of probabilities. The court must decide whether the fact occurred; it cannot return an intermediate finding that it might have occurred. Evidence must be assessed on the wide canvas, as an integrated whole rather than in separate compartments, and the reasoning process may be iterative. Human memory is fallible, particularly after the passage of time and during litigation. Findings affecting reliability on one issue may inform another, but they are relevant rather than determinative. Demeanour must not be the sole basis for credibility findings. Where documentary evidence is absent, inherent probabilities and overall plausibility assume greater importance. Applying those principles, the claim failed because exposure to asbestos while working for the defendant was not proved.

The claimant, the widow and administratrix of Brian Briggs’s estate, brought negligence proceedings against his former employer, Drylined Homes Ltd. She claimed under the Law Reform (Miscellaneous Provisions) Act 1934 and the Fatal Accidents Act 1976 following his death from mesothelioma.

The issues had narrowed to two cumulative factual questions relevant to breach of duty: whether, when it rained, carpenters came indoors and cut soffit boards near Mr Briggs while he was drylining; and whether those boards were likely to contain asbestos. The court had to determine both questions on the balance of probabilities.

1. Disposition. The claim was dismissed. The claimant failed to prove either that soffit boards were cut indoors near Mr Briggs when it rained or that the boards being cut were likely to contain asbestos. Those findings meant that the factual gateway to breach was not established.
2. Fact-finding principles. The burden rested on the claimant. Each fact in issue had to be determined on the balance of probabilities, by deciding whether it happened or did not happen. The court was required to assess the evidence globally and holistically, correlating the principal strands rather than evaluating them in isolation. The process could be iterative: a provisional conclusion on one issue could be reassessed after considering another.
3. Reliability and credibility. Memory was treated as fallible, especially when witnesses recalled events four decades earlier and after civil litigation had begun. A finding that a witness was unreliable on one matter could affect another, but did not determine it. Demeanour was not used as the sole basis for assessment; greater weight was placed on the substance, consistency, detail, independence and inherent plausibility of the evidence.
4. Application to Issue 1. The construction projects were rapid, highly organised developments using prefabricated materials. Soffits were fitted during the earlier exterior phase, whereas drylining occurred later, after the buildings were watertight. The boards were likely to have been narrow and pre-cut to width, requiring only trimming to length on scaffolding. Indoor cutting alongside drylining was impractical, and the proposed movement of boards between different construction phases to avoid rain was inherently implausible and unsupported by evidence. Issue 1 was therefore answered “No”.
5. Application to Issue 2. Although general evidence suggested that asbestos soffits were historically possible, and perhaps occurred in about 40 per cent of cases, the court preferred the evidence of a site supervisor who had personally observed timber or plywood soffits on the relevant developments. The claimant’s untested recollection was materially weakened by errors about the boards’ width and the circumstances of cutting. The court did not find deliberate dishonesty, but concluded that the recollection was inaccurate. Issue 2 was answered “No”.
6. The court emphasised that sympathy could not replace proof. The claim was dismissed.
