About this topic

Homicide covers murder, voluntary and involuntary manslaughter, and related offences such as infanticide and corporate manslaughter. Questions test the elements of each and the partial defences that reduce murder to manslaughter.

Know the qualifying triggers for loss of control, the test for diminished responsibility, the elements of unlawful act and gross negligence manslaughter, and the conditions for infanticide.

Key legislation and cases

  • Coroners and Justice Act 2009, ss.52-56
  • Homicide Act 1957, s.2
  • Infanticide Act 1938, s.1

Worked question 1 of 2Standard

DC Ferreira is reviewing a case where Ross, the mother of a baby boy aged 8 months, killed her child by shaking him. Medical evidence confirms Ross was suffering from postnatal depression at the time and that the balance of her mind was disturbed. The CPS considers whether Ross should be charged with murder or whether infanticide under s.1 of the Infanticide Act 1938 applies. Which of the following correctly states the elements of infanticide?

  1. AInfanticide applies where a mother kills her child under 12 months and was suffering from a recognised mental illness at the time - the disturbance must amount to a diagnosed psychiatric condition.
  2. BInfanticide applies where a woman by any wilful act or omission causes the death of her child under 12 months, and at the time the balance of her mind was disturbed by reason of her not having fully recovered from the effect of giving birth or by reason of the effect of lactation.
  3. CInfanticide is a partial defence only - it reduces murder to manslaughter but does not create a separate offence. A woman convicted under infanticide must be sentenced as for manslaughter.
  4. DInfanticide applies where a mother kills her child under 12 months while suffering from postnatal depression - the disturbance must be caused specifically by postnatal depression and not by any other cause.
Show answer and explanation
Answer: B

Under s.1(1) Infanticide Act 1938, a woman commits the offence of infanticide where by any wilful act or omission she causes the death of her child under 12 months, and at the time the balance of her mind was disturbed by reason of her not having fully recovered from the effect of giving birth or by reason of the effect of lactation. No specific diagnosis is required. Lactation is an expressly listed cause making the offence broader than postnatal depression alone. It creates both a separate offence and a partial defence to murder.

s.1(1) Infanticide Act 1938
s.1(1): "Where a woman by any wilful act or omission causes the death of her child being a child under the age of twelve months, but at the time of the act or omission the balance of her mind was disturbed by reason of her not having fully recovered from the effect of giving birth to the child or by reason of the effect of lactation consequent upon the birth of the child, then... she shall be guilty of felony, to wit of infanticide..."
  • A: No diagnosed psychiatric condition is required. The test is whether the balance of mind was disturbed - a legal test, not a clinical diagnosis. Postnatal depression may be the cause but a formal diagnosis is not needed.
  • C: Infanticide creates both a separate offence and a partial defence to murder. It is not manslaughter - a conviction of infanticide carries its own sentencing framework.
  • D: The Act specifies two causes: failure to recover from the effect of giving birth or the effect of lactation. It is not limited to postnatal depression - either cause is sufficient.
Worked question 2 of 2Standard

Whitfield is charged with the murder of her abusive partner, Ross. Whitfield killed Ross three hours after the most recent assault. She did not kill him immediately - she waited, became increasingly distressed, and then killed him. The defence raises loss of control under s.54 of the Coroners and Justice Act 2009. The prosecution argues that because the killing was not immediate, loss of control cannot apply. Which of the following correctly states the position?

  1. AThe prosecution is correct - under s.54 CJA 2009, loss of control is only available where the defendant killed immediately or almost immediately after the triggering event. A three-hour gap prevents the defence.
  2. BThe prosecution is correct - loss of control requires the killing to be spontaneous. A three-hour delay indicates a considered decision rather than a loss of control.
  3. CThe defence is available - under s.54 CJA 2009, loss of control does not require the killing to be immediate, but the longer the delay the less likely a jury will accept that a genuine loss of control occurred at the time of the killing.
  4. DThe defence is available and the three-hour gap does not automatically prevent it - under s.54(2) CJA 2009 it is not necessary for the loss of control to have been sudden. The jury must assess whether a loss of control actually existed at the time of the killing.
Show answer and explanation
Answer: D

Under s.54(2) Coroners and Justice Act 2009, the loss of control need not be sudden. This was a deliberate change from the old common law provocation defence, specifically intended to assist defendants in domestic abuse cases where the response may not be immediate. A three-hour gap is relevant evidence for the jury but does not automatically bar the defence.

s.54(2) Coroners and Justice Act 2009
s.54(2): "For the purposes of subsection (1)(a), it does not matter whether or not the loss of control was sudden."
  • A: s.54(2) CJA 2009 expressly provides that the loss of control need not be sudden. The prosecution's argument applies the old common law test which was reformed by the 2009 Act.
  • B: The requirement for spontaneity was part of the old common law provocation defence. s.54(2) specifically removed this requirement.
  • C: Option C correctly states the defence is available but overstates the legal position by saying a longer delay makes it "less likely." The correct statement is that s.54(2) expressly provides the loss need not be sudden and the gap is evidence for the jury.
