Recklessness is not ‘accidental’ when it comes to trespass: MacPhail v Allianz Insurance Plc [2023] EWHC 1035 (Ch).

The recent judgment in MacPhail v Allianz Insurance Plc puts public liability policies under the microscope and considers the question of ‘accidental trespass’.

The dispute revolves around a property constructed by a development company, HCL, that encroached upon the land of an adjoining owner. Mr MacPhail acquired the ownership of one of the developed properties and as part of the acquisition became a director of HCL. The property’s cellar was found to have encroached by around 18 inches, under a passageway belonging to Mr & Mrs Gueterbock, the adjoining neighbour. During construction of the development HCL stated it did not know conclusively who the passageway belonged to. The Gueterbocks brought a claim for trespass directly against MacPhail, which was settled for around £250,000 inclusive of damages, rectification costs and the Gueterbock’s legal costs. McPhail also incurred defence costs of c. £280,000.

MacPhail subsequently sought indemnity from Allianz, which had issued a policy to HCL. The policy contained provisions entitling MacPhail to claim under the Policy, despite not being a named insured. He also brought a claim against HCL for breach of contract. Allianz denied liability, arguing that the trespass was not accidental, therefore it did not trigger the insuring clause and fell outside the policy's coverage.

With the parties failing to reach a resolution McPhail issued a claim for breach of contract against HCL and for a declaration against Allianz. At trial the Court held the director of HCL was reckless in building under the entire width of the passageway and up to the neighbour’s flank wall as there was a risk that (1) the neighbours would complain that this was encroachment and (2) that they would be correct. Therefore, whilst the breach of contract claim against HCL for £530,000 damages succeeded, the declaration for an indemnity against Allianz did not. McPhail appealed against the finding that the trespass was not “accidental”, namely that (1) the Judge had misstated the legal test and (2) even if the test was correctly stated, the Judge had misapplied the law.

The appeal judgment found that the lower court’s explanation that HCL’s ‘willingness to take the risk’ that there was an actionable encroachment was merely a modern formulation of a decision that was to ‘court the risk’.

The Court relied upon an excerpt from Colinvaux and Merkin’s Insurance Contract Law (2022), which helpfully explains the distinction between accidental conduct and recklessness. It states: “It is settled law than an accident, for the purposes of an insurance policy, is from the assured's point of view an act, intentional or otherwise, which has unintended consequences. However, if the consequences were intended by the assured, or if the consequences while unintended were inevitable so that the assured can be regarded as having acted with reckless disregard for them, then it is clear from the authorities that there is no accident and the assured is precluded from recovery by the terms of the policy itself as well as on the grounds of public policy. The principle is that, by embarking upon a course of conduct that is obviously hazardous the assured intends to run the risk involved…

As such the Court was satisfied that the correct legal test had been applied.

It was the not the construction works itself, but the risk of trespass caused by that construction that was the relevant ‘action’ to which the question of mens rea was applied in order to determine whether the act was ‘reckless’ (not covered) or merely ‘accidental’ (and therefore would be covered). The Court was satisfied that where an insured was aware of the risk of a different interpretation of the boundary, even notwithstanding the finding of the relevant individual’s belief that the flank wall was the true boundary, this awareness meant the trespass was not an ‘accidental event’ that would trigger cover – there was a high degree of recklessness to the conduct. Given those findings the appeal was dismissed; the claim under the policy did not satisfy the test for “accidental”.

The question of how that belief came about is likely to be relevant in these sorts of cases. The outcome may have been different if professional advice had been taken and if, for example, such advice had confirmed the developer’s belief regarding the true boundary. It would have made the belief itself much more justifiable and less likely to be seen as reckless.

Practically, in circumstances where boundaries are often unclear and may be subject to later debate, property owners and developers should consider the option of defective title insurance cover, which may provide protection e.g. against the costs of rectification or paying damages for a breach, provided it is taken out before any dispute arises.

This case provides a refresher on the meaning of ‘accidental’, particularly in relation to policy interpretation and provides valuable guidance to both insurers and policyholders moving forward. In doing so it explores the borderline between reckless and non-reckless conduct (which will always be fact sensitive) and highlights the danger for an insured if they conduct themselves in a way that could be interpreted as “courting the risk”.
