Facts
- Lipman and his girlfriend voluntarily ingested LSD at her flat in the early hours.
- Under the influence of LSD, Lipman experienced hallucinations in which he believed he was descending through the earth and being attacked by snakes.
- During these hallucinations, Lipman violently assaulted his girlfriend and forced bed-sheets into her mouth, believing she was a snake.
- The girlfriend died as a result of asphyxiation and head injuries.
- Lipman was initially charged with murder, but the charge was reduced to manslaughter due to lack of evidence of intent to kill or cause grievous bodily harm during the hallucination.
Issues
- Can voluntary intoxication negate criminal liability for manslaughter, a basic intent offence?
- Does the automatism defence apply when loss of control arises from self-induced intoxication?
- Is reckless consumption of LSD sufficient to establish mens rea for constructive manslaughter when the fatal act occurs during unconscious or involuntary conduct?
Decision
- The trial judge ruled voluntary intoxication irrelevant for manslaughter and denied the automatism defence.
- Lipman was convicted of manslaughter.
- The Court of Appeal upheld the conviction, holding:
- Manslaughter is a basic intent crime to which voluntary intoxication is not a defence.
- Automatism does not apply if loss of control is self-induced; Lipman's condition resulted from his deliberate intake of LSD.
- Reckless consumption of LSD was sufficient as mens rea for constructive manslaughter, given the obvious risk of dangerous and unpredictable behaviour.
- The court distinguished between basic and specific intent crimes, confirming intoxication is a defence only to specific intent offences.
Legal Principles
- Voluntary intoxication does not excuse basic intent crimes, including manslaughter; public policy aims to protect against dangers from self-induced intoxication.
- The defence of automatism requires involuntariness not caused by the defendant’s conscious actions; self-induced intoxication precludes this defence.
- For basic intent crimes, recklessness is satisfied where the defendant chooses to become intoxicated.
- Reckless self-intoxication can fulfill the fault element for constructive manslaughter if harm results from a dangerous act performed without conscious control.
- The ruling was later approved in DPP v Majewski [1977] AC 443, reaffirming the rule concerning intoxication and basic intent offences.
Conclusion
The case confirms that voluntary intoxication and self-induced automatism cannot be relied upon as defences for basic intent crimes such as manslaughter; Lipman's reckless drug consumption fulfilled the required mental element and his conviction was upheld.
