SQE1 murder and manslaughter: what you must know and how it is tested

SQE1 murder and manslaughter questions test the elements of each offence, the partial defences that reduce murder to manslaughter, and the types of involuntary manslaughter. The mental element is what separates them. Read it with the wider Criminal Liability guide.

The rules to apply

Murder is the unlawful killing of a human being in being, under the King's peace, with intention to kill or cause really serious harm (GBH). Causation requires the defendant's act to be an operating and substantial cause of death. The defendant takes the victim as they find them (R v Blaue), and the chain breaks only for a free, deliberate and informed act of a third party, or an unforeseeable act. Intention is direct (aim or purpose) or oblique. Oblique intention is for the jury to find where the result was virtually certain and the defendant appreciated that (R v Woollin).

Voluntary manslaughter. There are two partial defences. Loss of control (Coroners and Justice Act 2009, ss54 to 56) needs a qualifying trigger, which is fear of serious violence or circumstances of an extremely grave character causing a justifiable sense of being seriously wronged, loss of self control, and that a person of the defendant's age and sex with normal tolerance and self restraint might have acted in the same way. Diminished responsibility (Homicide Act 1957, s2) requires an abnormality of mental functioning arising from a recognised medical condition, which substantially impaired the defendant's ability to understand their conduct, form a rational judgment or exercise self control, and which provides an explanation for the killing. The defendant must prove it on the balance of probabilities.

Involuntary manslaughter. Unlawful act manslaughter needs an unlawful criminal act, which is dangerous because a reasonable sober person would recognise the risk of some harm, and which causes death. The defendant need not foresee death (R v Church). Gross negligence manslaughter needs a duty of care, breach of it, a serious and obvious risk of death, causation and conduct so bad it should be judged criminal (R v Adomako). Corporate manslaughter is a separate offence for organisations.

Traps examiners use

• Requiring intention to kill. Intent to cause GBH suffices for murder.
• Requiring the defendant to foresee death in unlawful act manslaughter.
• Putting the burden on the prosecution for diminished responsibility.
• Using a tort act as the unlawful act. It must be a crime.
• Treating oblique intent as a rule of law. It is a matter of evidence for the jury.
• Overlooking that the victim's frailty does not break causation.

Worked question 1

Daryl, who intended only to frighten his neighbour, punches him once. The neighbour falls, strikes his head on the pavement and dies. Daryl is charged with unlawful act manslaughter. Which is correct?

• A. He is guilty only if he foresaw that death could result.
• B. He is not guilty because he did not intend to harm.
• C. He is guilty if the punch was an unlawful and dangerous act that caused death, even though he did not foresee death.
• D. He is guilty of murder because he caused death.
• E. He is not guilty because the death was an accident.

Answer: C. Unlawful act manslaughter needs the mental element of the unlawful act (here an assault) and that the act was dangerous. Foresight of death is not needed (R v Church). B and E ignore that a punch is an assault. D is wrong without intent to kill or cause GBH.

Worked question 2

Sade sets fire to a house at night, intending to frighten the occupant for an insurance scheme, and the occupant dies. Sade says she never intended to kill. What is the position on intention?

• A. She cannot be guilty of murder because she did not aim to kill.
• B. She is guilty of murder as a matter of law, because the death was foreseeable.
• C. A jury may find intention if death or GBH was a virtual certainty and she realised that.
• D. She is guilty only of arson.
• E. She is guilty of murder only if she wanted the occupant to die.

Answer: C. Oblique intention (R v Woollin) allows the jury to find intent where the result was a virtually certain consequence of her act and she appreciated that. It is not intention as a matter of law, and foreseeability is not enough (B). A and E wrongly limit intent to aim.

Checklist before you move on

• Unlawful killing with intent to kill or cause GBH?
• Causation: operating and substantial cause, any break?
• Partial defence: loss of control or diminished responsibility (burden)?
• Unlawful act: criminal, dangerous, caused death?
• Gross negligence: duty, breach, obvious risk of death, grossly negligent?
• Corporate or other offences?
