(2) Subsection (1) does not apply, and the person is not criminally responsible for the offence in those circumstances, if the Act is expressly to the contrary effect.
9.4 Mistake or ignorance of subordinate legislation
(1) A person can be criminally responsible for an offence even if, at the time of the conduct constituting the offence, he or she is mistaken about, or ignorant of, the existence or content of the subordinate legislation that directly or indirectly creates the offence or directly or indirectly affects the scope or operation of the offence.
(2) Subsection (1) does not apply, and the person is not criminally responsible for the offence in those circumstances, if:
(a) the subordinate legislation is expressly to the contrary effect; or
(c) at the time of the conduct, the subordinate legislation:
(i) has not been made available to the public (by means of the Register under the Legislative Instruments Act 2003 or otherwise); and
(ii) has not otherwise been made available to persons likely to be affected by it in such a way that the person would have become aware of its contents by exercising due diligence.
(3) In this section:
available includes available by sale.
subordinate legislation means an instrument of a legislative character made directly or indirectly under an Act, or in force directly or indirectly under an Act.
9.5 Claim of right
(1) A person is not criminally responsible for an offence that has a physical element relating to property if:
(a) at the time of the conduct constituting the offence, the person is under a mistaken belief about a proprietary or possessory right; and
(b) the existence of that right would negate a fault element for any physical element of the offence.
(2) A person is not criminally responsible for any other offence arising necessarily out of the exercise of the proprietary or possessory right that he or she mistakenly believes to exist.
(3) This section does not negate criminal responsibility for an offence relating to the use of force against a person.
Division 10
Circumstances involving external factors
10.1 Intervening conduct or event
A person is not criminally responsible for an offence that has a physical element to which absolute liability or strict liability applies if:
(a) the physical element is brought about by another person over whom the person has no control or by a non-human act or event over which the person has no control; and
(b) the person could not reasonably be expected to guard against the bringing about of that physical element.
10.2 Duress
(1) A person is not criminally responsible for an offence if he or she carries out the conduct constituting the offence under duress.
(2) A person carries out conduct under duress if and only if he or she reasonably believes that:
(a) a threat has been made that will be carried out unless an offence is committed; and
(b) there is no reasonable way that the threat can be rendered ineffective; and
(c) the conduct is a reasonable response to the threat.
(3) This section does not apply if the threat is made by or on behalf of a person with whom the person under duress is voluntarily associating for the purpose of carrying out conduct of the kind actually carried out.
10.3 Sudden or extraordinary emergency
(1) A person is not criminally responsible for an offence if he or she carries out the conduct constituting the offence in response to circumstances of sudden or extraordinary emergency.
(2) This section applies if and only if the person carrying out the conduct reasonably believes that:
(a) circumstances of sudden or extraordinary emergency exist; and
(b) committing the offence is the only reasonable way to deal with the emergency; and
(c) the conduct is a reasonable response to the emergency.
10.4 Self-defence
(1) A person is not criminally responsible for an offence if he or she carries out the conduct constituting the offence in self-defence.
(2) A person carries out conduct in self-defence if and only if he or she believes the conduct is necessary:
(a) to defend himself or herself or another person; or
(b) to prevent or terminate the unlawful imprisonment of himself or herself or another person; or
(c) to protect property from unlawful appropriation, destruction, damage or interference; or
(d) to prevent criminal trespass to any land or premises; or
(e) to remove from any land or premises a person who is committing criminal trespass;
and the conduct is a reasonable response in the circumstances as he or she perceives them.
(3) This section does not apply if the person uses force that involves the intentional infliction of death or really serious injury:
(a) to protect property; or
(b) to prevent criminal trespass; or
(c) to remove a person who is committing criminal trespass.
(4) This section does not apply if:
(a) the person is responding to lawful conduct; and
(b) he or she knew that the conduct was lawful.
However, conduct is not lawful merely because the person carrying it out is not criminally responsible for it.
10.5 Lawful authority
A person is not criminally responsible for an offence if the conduct constituting the offence is justified or excused by or under a law.
Part 2.4
Extensions of criminal responsibility
Division 11
11.1 Attempt
(1) A person who attempts to commit an offence is guilty of the offence of attempting to commit that offence and is punishable as if the offence attempted had been committed.
(2) For the person to be guilty, the person’s conduct must be more than merely preparatory to the commission of the offence. The question whether conduct is more than merely preparatory to the commission of the offence is one of fact.
(3) For the offence of attempting to commit an offence, intention and knowledge are fault elements in relation to each physical element of the offence attempted.
Note: Under section 3.2, only one of the fault elements of intention or knowledge would need to be established in respect of each physical element of the offence attempted.
