Facts
Hughes was driving on a road without a valid licence and without insurance when his vehicle was involved in a fatal collision with another vehicle. The driver of the other vehicle was killed. The prosecution relied on the licensing and insurance defaults to bring the case within section 3ZB, and the dispute was whether it also had to show anything wrong or causally relevant in Hughes's own driving.
Issue
Whether the offence of causing death by driving while unlicensed, disqualified or uninsured requires proof that the defendant's driving was in some way a cause of the death, or whether it is enough that the defendant was driving and the death resulted from the collision.
Held
The Supreme Court held that section 3ZB requires proof that the driving of the defendant, and not merely his presence on the road as a person without licence or insurance, was a cause of death. The driving must have involved some act or omission that contributed to the death, although it need not amount to careless driving.
Ratio
- The offence of causing death by driving contrary to section 3ZB demands a causal contribution by the defendant's driving, so that a driver who lacks a licence or insurance is not liable where the death resulted solely from another person's fault and nothing in his own driving contributed.
- The contribution need not be careless or blameworthy driving, but there must be some act or omission in the driving, beyond the mere fact of driving, which was open to proper criticism or otherwise a cause of the death.
Key reasoning
- Causing death by driving in the ordinary sense means that the driving contributed to the death. The offence is not rendered one of status merely because the driver lacked a licence or insurance.
- A literal reading that made the driver liable whenever a collision occurred would convert a serious homicide-type offence into one resting on unconnected regulatory defaults and would produce results Parliament cannot be taken to have intended.
- The court rejected both the view that no fault at all was required and a stricter view that carelessness had to be shown. The test lies between: some act or omission in the driving which contributed to the death.
Where it fits in the module
Hughes sits within the basic principles of criminal law because it tests how causation operates when a statutory offence combines a prohibited result with a status or regulatory element. It illustrates the rule that factual and legal causation require a contribution by the defendant's act, and that Parliament is presumed not to dispense with that requirement without clear words. It is useful to contrast with strict liability offences, where the result needs no fault, and with the general causation cases on intervening acts.
Criticisms
- The test of some act or omission open to proper criticism is vague and risks reintroducing fault by the back door, contrary to the text of an offence that is not defined in terms of negligence.
- The decision leaves unclear how much contribution is enough where the defendant's driving is lawful in every respect except for the missing licence or insurance.
- Treating status as irrelevant to causation may sit uneasily with the policy of the 2006 reforms, which were aimed at treating illegal drivers more severely when a death occurs.
