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?
- 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.
- 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.
- 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.
- 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
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.
- 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.
