5 HOMICIDE

C E N T R A L I S SU E S 1. The offence of murder is committed where the defendant caused the death of the victim and intended to kill or cause serious bodily harm. 2. There is a defence of loss of control to a charge of murder. To succeed the defendant must show that, at the time of killing, she had lost her self control as a result of a ‘qualifying trigger’ and that a person with a normal degree of tolerance and self-restraint would have responded in the same way. A qualifying trigger is a fear of serious violence or a justifiable sense of being seriously wronged. If the defence is successful the defendant is not guilty of murder, but guilty of manslaughter. 3. Diminished responsibility is only a defence to a charge of murder and if successful reduces the charge to manslaughter. To use it, a defendant needs to show that she had an abnormality of mental functioning which substantially impaired her ability to understand the nature of her conduct, form a rational judgment, or exercise self-control.

4. If a person kills another in the course of a suicide pact they will not be guilty of murder, but manslaughter. 5. A woman who kills a child under the age of one, while the ‘balance of her mind was disturbed’ following the birth, will commit the offence of infanticide and will not be guilty of murder or manslaughter. 6. Constructive manslaughter is committed where a defendant has carried out an unlawful and dangerous act which has caused the death of the victim. 7. Gross negligence manslaughter occurs where the defendant has killed the victim through a negligent act or omission which the jury believes to be sufficiently serious to justify a criminal conviction. 8. The Law Commission has recommended a restructuring of the law on murder and manslaughter. However, the government currently only intends to implement some of these reforms.
