Unlawful and Dangerous Act Manslaughter Self-Defence

[This checklist can be used instead of the Manslaughter Checklist if it is alleged that the accused committed unlawful and dangerous act manslaughter on or after 23 November 2005 and before 1 November 2014, and there is evidence from which a jury might infer that he or she was acting in self-defence.

The checklist is designed for use where it is alleged that the accused believed it was necessary to do what s/he did to defend him/herself. It will need to be modified if it is alleged that the accused acted to defend another person or to terminate the unlawful deprivation of liberty.

If it is alleged that the accused committed both unlawful and dangerous act manslaughter and criminal negligence manslaughter, see Checklist: Manslaughter Self-Defence.

If it is alleged that the accused committed criminal negligence manslaughter only, see Checklist: Criminal Negligence Manslaughter.

If it is alleged that the accused committed the manslaughter prior to 23 November 2005, see Common Law Self-Defence.

If it is allegedthat the accused committed the manslaughter on or after 1 November 2014, see Statutory Self-Defence.]

Manslaughter

Before you can convict the accused of manslaughter, the prosecution must prove, beyond reasonable doubt, that:

  1. The accused intended to commit the act that caused the victim’s death; and
  2. The accused’s act was unlawful; and
  3. The accused’s act was dangerous; and
  4. The accused’s act was not committed in self-defence.

 

Intention

1. Has the prosecution proved that the accused intended to commit the act that caused the victim’s death?

If Yes, then go to 2

If No, then the accused is not guilty of Manslaughter

Unlawful Act

2. Has the prosecution proved that the accused’s act that caused the victim’s death was unlawful?

If Yes, then go to 3

If No, then the accused is not guilty of Manslaughter

Dangerous Act

3. Has the prosecution proved that the accused’s act that caused the victim’s death was dangerous?

Consider – Would a reasonable person consider that an act of that kind would expose another person or other people to an appreciable risk of serious injury?

If Yes, then go to 4a

If No, then the accused is not guilty of Manslaughter

Self-Defence

4a. Has the prosecution proved that the accused did not believe that it was necessary to do what s/he did to defend him/herself?

Consider – What were the circumstances as perceived by the accused?

If Yes, then the accused is guilty of Manslaughter
(as long as you also answered Yes to Questions 1, 2 and 3)

If No, then go to 4b

4b. Has the prosecution proved that the accused did not have reasonable grounds for his/her belief that what s/he did was necessary to defend him/herself?

Consider – What were the circumstances as perceived by the accused?

If Yes, then the accused is guilty of Manslaughter
(as long as you also answered Yes to Questions 1, 2 and 3)

If No, then the accused is not guilty of Manslaughter
