8.2.5 - Checklist: Murder Self-Defence with Unlawful and Dangerous Act Manslaughter

Click here to obtain a Word version of this document for adaptation.

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

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 both unlawful and dangerous act manslaughter and criminal negligence manslaughter are available as alternative verdicts, use Checklist: Murder Self-Defence with Manslaughter.

If only criminal negligence manslaughter is available as an alternative verdict, use Checklist: Murder Self-Defence with Criminal Negligence Manslaughter.

If manslaughter is not available as an alternative verdict, use Checklist: Murder Self-Defence With No Manslaughter.

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

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

Murder

Before you can convict the accused of murder, there are four elements that the prosecution must prove beyond reasonable doubt:

  1. The accused caused the victim’s death; and
  2. The accused’s acts were conscious, voluntary and deliberate; and
  3. The accused intended to kill or cause really serious injury; and
  4. The accused did not believe that it was necessary to do what s/he did to defend him/herself from being killed or really seriously injured.

 

Cause of Death

1. Has the prosecution proved that the accused caused the victim’s death?

Consider – Were the accused’s actions a substantial or significant cause of the victim’s death?

If Yes then go to 2

If No, then the accused is not guilty of Murder

Conscious, Voluntary and Deliberate Acts

2. Has the prosecution proved that the accused’s actions which caused the death were conscious, voluntary and deliberate?

If Yes then go to 3

If No, then the accused is not guilty of Murder

Intention

3. Has the prosecution proved that at the time the accused did the acts that caused the victim’s death, s/he intended to kill or to cause really serious injury?

If Yes then go to 4

If No, then the accused is not guilty of Murder (but may be
guilty of Manslaughter – Go to 6)

Self-Defence

4. Has the prosecution proved that the accused did not believe that it was necessary to do what s/he did to defend him/herself from being killed or really seriously injured?

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

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

If No, then the accused is not guilty of Murder (but may be
guilty of Defensive Homicide – Go to 5)

Defensive Homicide

The offence of defensive homicide should only be considered if you answered "Yes" to Questions 1, 2 and 3 above, and "No" to Question 4.

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

5. There were no reasonable grounds for the accused to believe that what s/he did was necessary to defend him/herself from being killed or really seriously injured.

Defensive Homicide

5. Has the prosecution proved that there were no reasonable grounds for the accused to believe that what s/he did was necessary to defend him/herself from being killed or really seriously injured?

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

If Yes then the accused is guilty of Defensive Homicide (as long
as you also answered Yes to Questions 1, 2 and 3 and No to Question 4)

If No, then the accused is not guilty of Defensive Homicide

Manslaughter

The offence of manslaughter should only be considered if you answered "Yes" to Questions 1 and 2 above, and "No" to Question 3.

6. The accused intended to commit the act that caused the victim’s death; and

7. The accused’s act was unlawful; and

8. The accused’s act was dangerous; and

9. The accused’s act was not committed in self-defence.

Dangerous Act
