Introduction

The case of Nicola Steven Watt or Murray and Others against Lend Lease Construction Ltd ([2023] ScotCS CSIH_19) centers on a claim brought by the relatives of the late James Watt. Mr. Watt, who succumbed to mesothelioma in 2017, alleged that his illness was the result of negligent asbestos exposure during his employment with Lend Lease Construction Ltd (formerly Bovis Construction Limited) in 1963. The crux of the dispute lies in whether the defendants could have reasonably foreseen the risk of asbestos-related injury from the low-level, short-duration exposure Mr. Watt endured.

The parties involved include the pursuers, represented by Brodie KC and Shields Sol Adv, and the defenders, represented by Ellis KC, MacGregor, and Clyde and Co. (Scotland) LLP. The initial judgment by the Lord Ordinary favored the defendants, leading to an appeal brought by the pursuers.

Summary of the Judgment

The Scottish Court of Session upheld the decision of the Lord Ordinary, dismissing the pursuers' appeal against Lend Lease Construction Ltd. The court affirmed that the level of asbestos exposure Mr. Watt experienced was low and occurred over a short period, making it unreasonable to expect the defendants to foresee the risk of asbestos-related injury. The court emphasized that the defenders could not have been aware, based on the knowledge and regulations of the time, that such minimal exposure posed a health risk. Consequently, the claim of negligence and breach of statutory duty was unsuccessful.

Analysis

Precedents Cited

The judgment references several key cases to contextualize the issue of foreseeability in occupational asbestos exposure:

• Shell Tankers v Jeromson [2001] EWCA Civ 101: This case addressed the foreseeability of injury due to exposure levels and durations, establishing that employers are liable when they can reasonably foresee health risks from workplace hazards.
• Maguire v Harland & Wolff plc [2005] EWCA Civ 01: Reinforced the principle that employers must recognize and mitigate foreseeable risks associated with hazardous materials.
• Bussey v 00654701 Ltd [2018] EWCA Civ 243: Further clarified the extent to which employers should be aware of and address potential health risks from workplace exposures.
• Abraham v G Ireson & Son (Properties) Ltd and another [2009] EWHC 1958 (QB): Highlighted that modest and infrequent exposure levels may not meet the threshold of foreseeability required for negligence claims.
• YC v Secretary of State for the Home Department 2019 SC 285: Although not directly related to asbestos, this case was referenced regarding procedural aspects in assessing legal errors.

These precedents collectively emphasize that the foreseeability of harm is contingent on both the level and duration of exposure, as well as the existing knowledge about associated risks at the time.

Legal Reasoning

The court's decision hinged on the interpretation of foreseeability within the context of asbestos exposure. The Lord Ordinary determined that Mr. Watt's exposure to asbestos was secondary, intermittent, and minimal in duration (three to four days). Given the standards and regulations of the early 1960s, the court concluded that it was not reasonably foreseeable to the employers that such low-level exposure would result in mesothelioma.

The court meticulously analyzed the expert testimonies, giving weight to Professor Roger Willey's assessment that the exposure was insufficiently substantial to pose a significant health risk. Furthermore, the court differentiated this case from Abraham, stressing that the Lord Ordinary had independently assessed the evidence without erroneously adopting factual findings from previous cases.

Impact

This judgment reinforces the principle that employer liability for asbestos-related illnesses is closely tied to the foreseeability of harm based on exposure levels and existing knowledge. Employers are not held liable for minimal or incidental exposures that do not meet the threshold of foreseeable risk, especially in historical contexts where awareness of hazards was limited.

For future cases, this ruling underscores the importance of establishing a clear link between the level of exposure and the resultant health risks. It delineates the boundaries within which employers must operate to be held accountable, emphasizing that mere presence of hazardous materials does not automatically translate to liability absent reasonable foreseeability of harm.

Complex Concepts Simplified

Foreseeability

Foreseeability in legal terms refers to whether a reasonable person or entity could predict that their actions or inactions might result in harm. In this case, it questions whether the employer could have anticipated that exposure to low levels of asbestos would cause mesothelioma.

Mesothelioma

Mesothelioma is a rare and aggressive form of cancer primarily caused by asbestos exposure. It typically affects the lining of the lungs (pleural mesothelioma) and has a long latency period, often developing decades after exposure.

Negligence

Negligence is a failure to exercise the care that a reasonably prudent person would exercise in similar circumstances. In employment contexts, it often relates to how employers manage workplace hazards and protect employees from known risks.

Statutory Duty

A statutory duty is a legal obligation imposed by legislation. Employers have statutory duties to ensure workplace safety, which includes minimizing exposure to hazardous substances like asbestos.

Conclusion

The Court of Session's affirmation of the Lord Ordinary's decision in [2023] ScotCS CSIH_19 underscores the nuanced approach courts must take in cases involving occupational hazards. By meticulously evaluating the level and duration of exposure against the existing knowledge base, the court ensures that employer liability is fairly assessed. This judgment serves as a pivotal reference point for future asbestos-related claims, delineating the boundaries of foreseeability and emphasizing the critical role of evidence in establishing negligence. Ultimately, it reinforces the necessity for employers to maintain robust safety standards while recognizing that liability is contingent upon a reasonable anticipation of risk.
