Williams v University of Birmingham & Anor
Factual and Procedural Background
On 24 November 2006, the deceased, aged 54, died of malignant mesothelioma. The Plaintiff, the widow, initiated proceedings on behalf of the deceased’s estate and dependents against the Defendant, the University, where the deceased studied physics from 1970 to 1974. During his final year, the deceased conducted experiments in a service tunnel on University premises, which contained asbestos lagging on heating pipes. Asbestos dust tests in the 2000s confirmed presence of various asbestos types in the tunnel. The deceased later worked as a pilot for Company B at Heathrow Airport, where asbestos exposure was also alleged but claims against Company B were withdrawn.
The University admitted some exposure to asbestos during the experiments but contended that such exposure was de minimis and not causative of the mesothelioma. A liability-only trial was held in 2009 before HHJ Belcher. The Plaintiff claimed breach of common law duty of care, which the University denied, also disputing causation. Evidence included witness statements, expert medical and occupational hygiene reports, and post-mortem asbestos fibre analysis.
The trial judge found the asbestos lagging was in poor condition in 1974, leading to asbestos dust exposure above de minimis levels and that the University was negligent in breaching its duty of care. The judge concluded the exposure materially increased the risk of mesothelioma and that causation was established on a balance of probabilities, awarding damages to the Plaintiff. The University appealed with leave.
Legal Issues Presented
- What is the correct legal test for breach of duty in negligence claims involving mesothelioma, and did the trial judge apply this correctly?
- Was the trial judge entitled to find that the asbestos lagging was in poor condition in 1974, and what are the implications of this finding?
- Did the trial judge apply the correct legal test concerning causation, and what are the consequences of that application?
Arguments of the Parties
Appellant's Arguments (University)
- The trial judge applied an incorrect legal test for breach of duty by focusing on whether the exposure was a "material increase in risk" rather than on whether the University should have reasonably foreseen the risk of asbestos-related injury based on the 1974 knowledge and standards.
- The judge’s factual finding that the lagging was in poor condition was challenged as unsupported by evidence, and no finding was made that such condition should have alerted the University to a foreseeable risk of injury, undermining the breach of duty conclusion.
- Regarding causation, the judge misinterpreted section 3 of the Compensation Act 2006 and failed to apply the correct test established by the Supreme Court in Sienkiewicz v Grief (UK) Ltd, which requires proof that the defendant’s exposure materially increased the risk of mesothelioma compared to other exposures.
- The exposure at the University was minimal relative to other asbestos exposures the deceased must have had, thus not materially increasing the risk of disease.
Appellee's Arguments (Plaintiff)
- The trial judge correctly identified and applied the legal and factual issues, including the necessity to find exposure was more than de minimis both for breach of duty and causation.
- The judge properly found the lagging was in poor condition and that this resulted in material asbestos exposure, which the University should have foreseen as a risk in 1974.
- The judge’s causation conclusion was consistent with the law in Sienkiewicz v Grief (UK) Ltd and did not require comparative assessment of exposures; it suffices that the defendant’s exposure materially increased the risk of mesothelioma.

Court's Reasoning and Analysis
The court analyzed the trial judge’s approach to breach of duty, factual findings, and causation in light of established mesothelioma law and statutory provisions. It emphasized that breach of duty requires reasonable foreseeability of risk based on knowledge at the relevant time (1974), not the modern understanding of asbestos dangers. The trial judge’s test conflated breach of duty with causation by focusing on whether the exposure caused a "material increase in risk" at the breach stage, which was legally incorrect.
Regarding facts, the court upheld the trial judge’s finding that the asbestos lagging was in poor condition in 1974, supporting the conclusion that asbestos dust exposure occurred. However, the court found no clear finding that the University ought to have foreseen an unacceptable risk of injury from that exposure based on 1974 knowledge and standards. The court noted the relevance of contemporaneous regulatory guidance (Technical Data Note 13, 1970) indicating exposure thresholds below which risk was not reasonably foreseeable.
On causation, the court rejected the appellant’s argument requiring comparative analysis of exposures but found the trial judge did not clearly apply the correct legal test. The judge’s statement that the question of whether exposure was de minimis relates only to breach of duty was incomplete; causation requires proof that the tortious exposure materially increased the risk of contracting mesothelioma. Despite this, the court accepted that the trial judge intended to find causation and that this finding was not unreasonable on the evidence.
Ultimately, the court allowed the appeal on breach of duty law and factual findings but rejected the appeal on causation.
Holding and Implications
The court's decision was to ALLOW THE APPEAL on the grounds that the trial judge misdirected on the legal test for breach of duty and failed to make necessary findings that the risk of asbestos-related injury was reasonably foreseeable to the University in 1974. Consequently, the findings supporting breach of duty were unsustainable. However, the court upheld the trial judge’s finding on causation as sufficient and not impeachable.
The direct effect is that the Plaintiff’s claim fails due to lack of proof of breach of duty under the correct legal test. No new precedent was established; rather, the court reaffirmed established principles regarding the assessment of breach of duty and causation in mesothelioma cases, emphasizing the importance of contemporaneous knowledge and standards in evaluating negligence.
