“Under s.1(2) provision is made for infanticide to be an alternative verdict available to the jury trying a mother for murder of her infant child. It does however require evidence that the ‘balance of her mind was disturbed’ either because the mother has not recovered from giving birth to the child, or the effect of lactation on her. No other circumstances are relevant.”
“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, if the circumstances were such that but for this Act the offence would have amounted to murder or manslaughter, she shall be guilty of felony, to wit of infanticide, and may for such offence be dealt with and punished as if she had been guilty of the offence of manslaughter of the child.”
“It seems to the court that if at the time of death the original wound is still an operating cause and a substantial cause then the death can properly be said to be the result of the wound, albeit that some other cause of death is also operating. Only if it can be said that the original wounding is merely the setting in which another cause operates can it be said that the death does not result from the wound. Putting it another way, only if the second cause is so overwhelming as to make the original wound merely part of the history can it be said that the death does not flow from the wound.”
“There are many examples of two or more concurrent causes of an event, all effective causes in law. A road traffic accident is one of the commoner cases, for such events are only too often the result of a combination of acts or omissions on the part of two or more persons. Where there are multiple legally effective causes, whether of a road accident or of any other event, it suffices if the act or omission under consideration is a significant (or substantial) cause, in the sense that it is not de minimis, or minimal. It need not be the only or the principal cause. It must, however, be a cause which is more than de minimis, more than minimal: see R v Hennigan[1971] 55 Cr App R 262 .”
