AI confidence in this short overview: high
This appeal concerned an insurer's claim under regulation 24 for underpinning costs said to result from Enfield Council's refusal (2 Feb 2018) to consent to felling an oak (T1) protected by a TPO. The tribunal found that, on the balance of probabilities as of the decision date, the claimant failed to prove T1 and its roots had extracted sufficient moisture to cause the subsidence to the garage and extension. Because causation was not established, the tribunal dismissed the claim and did not decide foreseeability, mitigation or quantum.
Ratio decidendi
This summary is intended to identify the ratio decidendi, meaning the legal reasons for deciding and the binding part of the decision.
AI confidence in this ratio decidendi summary: high
The decision turned on causation: for a regulation 24 claim premised on tree-induced subsidence the claimant must prove, on the balance of probabilities and by reference to the evidence available to the authority at the date of refusal, that the specific tree’s roots caused sufficient subsoil desiccation to produce the damage alleged. The absence of convincing evidence of subsoil desiccation, seasonal shrinkage/recovery at the affected structure, or a clear linkage of recovered roots to the specific tree undermines a claimant’s case.
Obiter dicta
This summary is intended to identify obiter dicta, meaning observations made by the way that were not necessary to deciding the case and are not binding.
AI confidence in this obiter dicta summary: medium
The judgment commented (obiter) that expert opinion based on speculation about post-investigation changes in subsoil without further site investigation carries limited weight, and that where multiple potential causes (e.g. drainage failure, other nearby trees) exist a focused investigation behind each affected structure is required to distinguish a particular tree’s contribution.
