Factual and Procedural Background
The Defendant's lorry negligently collided with the Plaintiff's parked and unattended vehicle on 20 February 2021, causing damage that rendered the Plaintiff's vehicle undriveable and necessitated repairs. The Plaintiff regularly used the vehicle for work and personal purposes and had no reasonable alternative transport during repairs. Consequently, the Plaintiff hired a replacement vehicle on credit hire terms for 36 days, incurring hire charges totaling £21,588.72, alongside repair and recovery costs.
The Defendant admitted negligence but denied the claim for hire charges, arguing that the Plaintiff failed to mitigate losses by hiring unnecessarily, excessively, or inappropriately. The Defendant further contended that the Plaintiff’s vehicle lacked a valid MOT certificate at the time of the accident, relying on this to invoke the doctrine of ex turpi causa and a separate "causation defence," asserting that no compensable loss arose due to the vehicle’s unroadworthy status.
The trial judge found the Plaintiff had a need for a replacement vehicle and that hiring was reasonable, but accepted the causation defence and disallowed the hire charges claim. On first appeal, this decision was upheld. The Plaintiff now appeals to this Court.
Legal Issues Presented
- Whether the Plaintiff is entitled to recover hire charges for a replacement vehicle despite the absence of a valid MOT certificate on the damaged vehicle at the time of the accident.
- Whether the doctrine of ex turpi causa bars the Plaintiff's claim for hire charges.
- Whether the Defendant’s "causation defence" — that no compensable loss arose because the Plaintiff’s vehicle was unroadworthy and unlawful to use — is valid and distinct from ex turpi causa.
- Whether the Plaintiff took reasonable steps to mitigate loss by hiring the replacement vehicle.
Arguments of the Parties
Defendant's Arguments
- The Plaintiff’s claim for hire charges is barred by ex turpi causa due to the absence of a valid MOT certificate on the damaged vehicle.
- The Plaintiff failed to mitigate loss reasonably by hiring a vehicle when unnecessary, for too long, at excessive cost, or an inappropriate vehicle.
- The "causation defence" asserts that the Plaintiff suffered no compensable loss because the vehicle was unroadworthy and unlawful to use on public roads, thus no loss of use claim arises.
- Reliance on precedent, particularly Agheampong v Allied Manufacturing (London) Ltd, to support the ex turpi causa plea.
Plaintiff's Arguments
- The Plaintiff had a genuine need for transport met by the damaged vehicle prior to the accident, and the Defendant’s tort caused inconvenience due to loss of use.
- The absence of a valid MOT certificate does not negate the loss of use or the reasonable need to hire a replacement vehicle.
- The "causation defence" is essentially a disguised illegality defence that fails to properly consider proportionality and the nature of loss.
- The claim for hire charges is reasonable, necessary, and consistent with established principles of mitigation and loss of use claims.

Court's Reasoning and Analysis
The Court carefully analysed the nature of loss of use claims, emphasizing that the compensable loss is inconvenience arising from deprivation of the vehicle's use, not merely financial loss. Established principles from Lagden and related cases confirm that a claimant must prove a justifiable need for replacement transport and that mitigation must be reasonable.
The Defendant's "causation defence" was scrutinized and rejected as a misconceived attempt to bar recovery on grounds of illegality without proper regard to proportionality. The Court distinguished this defence from the doctrine of ex turpi causa, noting that ex turpi causa requires a public policy balancing exercise and proportionality analysis, which the causation defence lacked.
The Court found that the absence of a valid MOT certificate, a relatively minor criminal offence punishable by a modest fine, did not vitiate the Plaintiff’s claim for hire charges. The offence was deemed insufficiently serious to justify denying compensation for inconvenience caused by the Defendant’s tort. The Court also noted that allowing recovery does not undermine the criminal law’s effectiveness but that denying it would impose a disproportionate penalty beyond the criminal sanction.
The Court rejected the Defendant's argument that the Plaintiff suffered no loss because the vehicle was unlawful to use, holding that loss of use and inconvenience arise regardless of the MOT status. The Court further observed that acceptance of the causation defence would lead to absurd outcomes, potentially barring claims for minor defects equally punishable under road traffic law.
Applying the framework from Pattni, the Court concluded the Plaintiff needed to hire a replacement vehicle, the hire was reasonable, and no evidence showed a cheaper alternative was available. The Plaintiff was not impecunious, and no rate difference was proven.
Consequently, the Court allowed the Plaintiff’s appeal on the causation defence issue, affirming the trial judge’s rejection of ex turpi causa as a bar to the hire charges claim.
Holding and Implications
The Court's final ruling is IN FAVOUR OF THE PLAINTIFF on the appeal against the rejection of the hire charges claim based on the causation defence.
The Plaintiff is entitled to recover the full hire charges incurred for the replacement vehicle, as the absence of a valid MOT certificate does not negate the compensable inconvenience caused by the Defendant’s tort. The doctrine of ex turpi causa does not bar the claim, and the causation defence is rejected as misconceived and disproportionate.
This decision directly restores the Plaintiff’s entitlement to compensation for loss of use mitigated by reasonable hire costs. It does not establish a new precedent limiting ex turpi causa or causation principles beyond the facts of this case but clarifies that minor regulatory offences such as lacking a valid MOT do not justify denying loss of use claims in tort.
