Part 11 Division 3
Division 3 Self-defence
418   Self-defence—when available
(1)  A person is not criminally responsible for an offence if the person carries out the conduct constituting the offence in self-defence.
(2)  A person carries out conduct in self-defence if and only if the person believes the conduct is necessary:
(a)  to defend himself or herself or another person, or
(b)  to prevent or terminate the unlawful deprivation of his or her liberty or the liberty of another person, or
(c)  to protect property from unlawful taking, destruction, damage or interference, or
(d)  to prevent criminal trespass to any land or premises or to remove a person committing any such criminal trespass,
and the conduct is a reasonable response in the circumstances as he or she perceives them.
419   Self-defence—onus of proof
In any criminal proceedings in which the application of this Division is raised, the prosecution has the onus of proving, beyond reasonable doubt, that the person did not carry out the conduct in self-defence.
420   Self-defence—not available if death inflicted to protect property or trespass to property
This Division does not apply if the person uses force that involves the intentional or reckless infliction of death only:
(a)  to protect property, or
(b)  to prevent criminal trespass or to remove a person committing criminal trespass.
421   Self-defence—excessive force that inflicts death
(1)  This section applies if:
(a)  the person uses force that involves the infliction of death, and
(b)  the conduct is not a reasonable response in the circumstances as he or she perceives them,
but the person believes the conduct is necessary:
(c)  to defend himself or herself or another person, or
(d)  to prevent or terminate the unlawful deprivation of his or her liberty or the liberty of another person.
(2)  The person is not criminally responsible for murder but, on a trial for murder, the person is to be found guilty of manslaughter if the person is otherwise criminally responsible for manslaughter.
422   Self-defence—response to lawful conduct
This Division is not excluded merely because:
(a)  the conduct to which the person responds is lawful, or
(b)  the other person carrying out the conduct to which the person responds is not criminally responsible for it.
423   Offences to which Division applies
(1)  This Division applies to offences committed before or after the commencement of this Division, except as provided by this section.
