R v Lamb

Facts

The defendant and a friend were playing with a revolver as a joke. It had five chambers, two of which held bullets, neither of which was opposite the barrel. The defendant pointed it at his friend and pulled the trigger, believing no round would be fired. The cylinder turned, a bullet was fired and the friend was killed. Neither man apprehended any harm. The defendant was convicted of manslaughter.

History

The defendant was convicted of manslaughter at trial. He appealed to the Court of Appeal.

Issue

Whether pointing a revolver at a friend and pulling the trigger, both men believing it was safe, was an assault and so an unlawful act sufficient to found a conviction for unlawful act manslaughter.

Held

Appeal allowed; conviction for manslaughter quashed.

Ratio

• For unlawful act manslaughter the act must itself be a criminal offence. Assault requires that the victim apprehend immediate unlawful violence; where neither party thought the weapon would fire, no assault was committed and so there was no unlawful act to support manslaughter.

Key reasoning

• Constructive manslaughter requires an unlawful act that is dangerous and causes death.
• The unlawful act must be a criminal offence, not merely a civil wrong.
• Assault requires the victim to apprehend the infliction of immediate unlawful force.
• Because both men believed the gun was safe, the friend did not apprehend that violence was about to be used against him, so there was no assault.
• Since there was no assault, there was no unlawful act to serve as the basis for constructive manslaughter.

Where it fits in the module

This case is central to the Oxford Criminal Law module's examination of constructive manslaughter, illustrating the requirement that the unlawful act be independent of the death and that assault requires apprehension of violence. It contrasts with Church [1966] (where the unlawful act was assault occasioning actual bodily harm) and anticipates the broader approach in DPP v Newbury and Jones [1977]. It also connects to debates about consent in non-fatal offences and the boundary between unlawful act and gross negligence manslaughter.

Criticisms

• The decision allows a defendant who creates a lethal risk to escape liability by framing the conduct as a consensual game.
• It creates an anomaly: the same physical act is criminal if the victim is frightened but not if the victim is a willing participant.
• The focus on the technical elements of assault overlooks the defendant's gross recklessness and moral culpability.
• It may incentivise defendants to claim the victim consented to dangerous activities to avoid a manslaughter conviction.
