## Facts

- Mr. Delaney was a passenger in a vehicle driven by Mr. Pickett on 25 November 2006.
- Both individuals were engaged in the possession and supply of cannabis at the time of the journey.
- Mr. Pickett drove negligently and caused a serious road traffic accident in which Mr. Delaney sustained severe head injuries and brain damage.
- A substantial quantity of cannabis was found in the vehicle after the accident.
- Mr. Delaney brought a negligence claim against Mr. Pickett and also sought compensation from the Motor Insurers' Bureau (MIB) as Mr. Pickett's insurer had avoided the policy.
- Mr. Pickett argued that the claim should be barred under the ex turpi causa doctrine due to Mr. Delaney's involvement in illegal drug activity.
- The MIB relied on clause 6(1)(e)(iii) of the MIB Agreement, which excludes claims where the claimant knew the vehicle was being used in the course or furtherance of crime.

## Issues

1. Whether the claimant's participation in the possession and supply of cannabis barred his negligence claim against the driver under the ex turpi causa doctrine.
2. Whether there was a sufficient causal connection between the illegal conduct and the injuries to trigger the illegality defence.
3. Whether the claimant could recover under the MIB Uninsured Drivers Agreement given the crime exclusion clause.

## Decision

- The Court of Appeal held that the ex turpi causa defence did not bar the claim against Mr. Pickett.
- The court found that the illegal drug activity was incidental to the circumstances of the accident rather than its direct cause.
- Applying the test from Gray v Thames Trains Ltd [2009] UKHL 33, the damage was caused by Mr. Pickett's negligent driving, not by the criminal activity itself.
- Therefore, Mr. Delaney succeeded in his negligence claim against Mr. Pickett.
- However, the Court of Appeal (by a majority of 2-1) dismissed the claim against the MIB.
- The MIB successfully relied on clause 6(1)(e)(iii) of the Uninsured Drivers Agreement, which excludes recovery where the claimant knew or ought to have known the vehicle was being used in the course or furtherance of crime.
- The court held that transporting cannabis for drug dealing constituted using the vehicle in furtherance of a crime.

## Legal Principles

- The ex turpi causa non oritur actio doctrine does not automatically bar claims simply because the claimant was engaged in illegal activity at the time of injury.
- For the illegality defence to succeed in tort, there must be a sufficient causal connection between the illegal conduct and the harm suffered.
- The relevant test is whether the illegal activity was the direct cause of the damage or merely incidental to it.
- Where the criminal activity simply provides the occasion for tortious conduct but does not cause the injury, the defence will not apply.
- The MIB Uninsured Drivers Agreement contains specific exclusion clauses, including clause 6(1)(e)(iii) which bars recovery where the vehicle was being used in the course or furtherance of crime.
- This crime exclusion applies regardless of whether the ex turpi causa defence succeeds against the tortfeasor.

## Conclusion

The Court of Appeal clarified that participation in illegal activity does not automatically bar a negligence claim against a tortfeasor. The critical question is whether the illegality directly caused the damage or was merely incidental to it. In this case, the negligent driving caused the injuries, not the drug offences, so the claim against Mr. Pickett succeeded. However, the separate MIB Agreement exclusion for vehicles used in furtherance of crime operated independently to bar recovery from the insurers.
