Barrowfen Properties Ltd v Patel & Ors ([2025] EWCA Civ 39)

Introduction

Barrowfen Properties Ltd v Patel & Ors ([2025] EWCA Civ 39) is a landmark judgment from the England and Wales Court of Appeal (Civil Division) that delves deep into the principles governing loss of chance in claims arising from breaches of fiduciary duty and negligence. The case revolves around a complex dispute within a family-owned property development company, Barrowfen Properties Ltd ("Barrowfen"), where internal conflicts and alleged misconduct led to significant financial losses. The key issues addressed include the proper application of loss of chance percentages, the treatment of benefits obtained through mitigation, and the calculation of damages and interest resulting from the breaches.

Summary of the Judgment

Barrowfen Properties Ltd brought claims against Girish Patel ("Girish"), a former director, and the solicitors firm S&B for breach of fiduciary duty and negligence. The core of the dispute was the delay in developing a commercial property in Tooting, London, which resulted in a loss of rental income and additional costs. The initial judgment by Leech J addressed issues of liability and causation, awarding Barrowfen equitable compensation and damages, which were later reduced due to the increased capital value from a revised development scheme undertaken by Barrowfen as a mitigation measure.

S&B cross-appealed on two grounds: the timing of deducting the increased capital value before applying the loss of chance percentage and the calculation of interest as damages. The Court of Appeal dismissed Barrowfen's appeals regarding both S&B and Girish, and also dismissed S&B's appeal concerning the deduction method. However, the court allowed S&B's cross-appeal regarding the interest calculation to a limited extent, adjusting the amount awarded to Barrowfen.

The judgment extensively references several key cases that have shaped the legal understanding of loss of chance and the mitigation of damages:

• British Westinghouse v Underground Electric [1912] AC 673: Established basic principles for mitigation of damages, emphasizing the need to account for benefits obtained through reasonable mitigation steps.
• Fulton Shipping v Globalia Business Travel [2017] 1 WLR 2581: Clarified that benefits must be causally linked to the breach or mitigation efforts.
• Primavera v Allied Dunbar [2003] PNLR 12: Discussed collateral benefits and their treatment in damage assessments.
• Needler Financial Services v Taber [2002] 3 All ER 501: Highlighted the importance of causation in determining whether benefits are part of a continuous transaction.
• Hartle v Laceys [1999] Lloyd's Rep PN 315: Addressed the application of loss of chance percentages in the context of property sales.
• The Baltic Surveyor [2002] 1 Lloyd's Rep 623; Examined the concept of betterment in property damage cases.
• Harbutt's Plasticine v Wayne Tank and Pump [1970] 1 QB 447; Provided examples where benefits from mitigation did not require credit unless they resulted in a pecuniary advantage.

• Thai Airways International v KI Holdings [2016] 1 All ER (Comm) 675 ("Thai Airways"): Distinguished between different types of benefits and their treatment in damage calculations.

These precedents collectively informed the court's approach to assessing damages, particularly in relation to how benefits obtained through mitigation should be accounted for.

Legal Reasoning

The court's primary focus was on the proper application of the loss of chance doctrine and the necessity to credit any benefits Barrowfen obtained through its mitigation efforts. The judge applied the principles from British Westinghouse and Fulton Shipping to determine that Barrowfen must give credit for the increased developer's profit resulting from the revised development scheme. This profit was viewed as a consequence of Barrowfen's steps to mitigate its losses, akin to the replacement of defective turbines in British Westinghouse.

The court meticulously analyzed whether the benefits (increased developer's profit) were directly caused by the breaches of duty or were part of a continuous transaction initiated by those breaches. It concluded that once Barrowfen completed the revised development scheme, its subsequent commercial decisions to retain the property were independent and not causally linked to the breaches by Girish and S&B. Therefore, while Barrowfen could not neglect to credit the increased capital value, it should not consider future finance costs and lost investment opportunities arising from independent commercial decisions.

Regarding the calculation of interest as damages, the court addressed whether the credit for increased developer's profit should be deducted before or after applying the loss of chance percentage. The court upheld the judge's initial decision to deduct this credit prior to applying the percentage, ensuring that the loss of chance was accurately reflected in the damages awarded.

Impact

The judgment has significant implications for future cases involving loss of chance, particularly in scenarios where claimants undertake mitigation measures that result in partial benefits. It reinforces the necessity to:

• Ensure that any benefits obtained through mitigation are directly causally linked to the breach or negligence.
• Apply loss of chance percentages appropriately, considering the probabilistic nature of the claimant's loss.
• Distinguish between benefits arising from mitigation efforts and independent commercial decisions made after mitigation.

Additionally, the clarification on the deduction timing before applying loss of chance percentages provides a clearer framework for assessing damages, ensuring that claimants cannot unjustly benefit from their own mitigation efforts while defendants are held accountable for their actions.

Complex Concepts Simplified

Loss of Chance

Loss of Chance refers to the reduction in the probability of a favorable outcome due to a breach of duty or negligence. Instead of quantifying the exact loss, courts assess the diminished likelihood of achieving a beneficial result and award damages based on that probability.

Mitigation of Losses

Mitigation of losses obligates the claimant to take reasonable steps to reduce the extent of their losses. If the claimant successfully mitigates their losses, any subsequent benefits or reduced losses resulting from these actions must be accounted for in the damages awarded.

Continuous Transaction

A continuous transaction implies that the initial breach or negligence and the subsequent actions (such as mitigation) are part of a single, ongoing sequence of events. Benefits or losses arising from this continuous course are directly attributable to the initial wrongdoing.

Betterment

Betterment occurs when the claimant's actions to mitigate losses result in an improved position beyond merely restoring the status quo ante. In such cases, any benefits derived from betterment must be credited against the damages owed.

Conclusion

The Court of Appeal's decision in Barrowfen Properties Ltd v Patel & Ors serves as a pivotal reference point for understanding the nuanced application of the loss of chance doctrine in the context of breach of fiduciary duty and negligence. By meticulously balancing the claimant's mitigation efforts and the resultant benefits, the judgment ensures a fair and equitable assessment of damages. It underscores the importance of causal linkage in recognizing benefits from mitigation and provides clear guidance on the timing of deductions when applying loss of chance percentages. This decision not only clarifies existing legal principles but also sets a robust precedent for handling similar complex disputes in the future.
