Not every act that would constitute a crime may result in a criminal conviction. There are certain defences that exist at law that can reduce or remove criminal culpability. At Rep-Revive Criminal Lawyers, we believe everyone should have at least a basic knowledge of their legal defences in order to minimize the likelihood of an injustice occurring at your expense. We’d wager you’ve heard of self-defence. See how many defences you know by the end of this blog and know that even more defences exist than the ones discussed below. This article examines the some of the defences available at law and when they arise.
Most crimes require that they be voluntary acts under your control. Automatism is a state where your muscles act without any control by your mind or lacking your consciousness. However, the destruction of your control cannot be voluntary, for example brought on by you choosing to become drunk or consuming drugs or driving tired at the wheel.
Claim of Right
Pursuant to Section 9.5 of the Criminal Code, if at the time of the offence you were under a mistaken belief that you had a right to possess property, you cannot be held criminally responsible. This defence however does not negate criminal liability for any offence involving the use of force (violence) against a person.
If your criminal actions were motivated by a serious threat against you, your family or others and serious injury or death would have resulted if you did not perform the criminal act, this defence may be available to you. Some of the requirements for this defence were set out in Bassett. The duress must involve the threat of imminent peril of death or serious injury, which operates in your mind to overbear your will. You must reasonably believe in the threat made against you, your family or other people. The duress must be an order to do something specific (for example you cannot be threatened with harm to repay money then go choose to rob someone to repay the debt). In order to be eligible for this defence, your circumstances must be so severe that your will is effectively constrained completely.
Honest and Reasonable Mistake
Under Section 9 of the Criminal Code, if you are under a mistaken belief about the facts at the time of committing the criminal act, you will not be held criminally responsible for the offence. However, this defence is only available to offences of strict liability.
This is not a defence, however, it can be raised as a defence to specific intent offences, such as maliciously inflicting grievous bodily harm with intent to inflict grievous bodily harm. Thus, pursuant to Section 428C of the Crimes Act, evidence of intoxication at the time the offence was committed may be considered in determining whether the accused had the intent required to commit that offence.
In the Local Court, a magistrate can decide that a person should be dealt with under mental health legislation instead of being subjected to sanctions for criminal conduct. Of importance here is that in the Local Court, the mental illness does not have to have existed at the time the offence was committed, but at anytime during Local Court proceedings. However, Mental Illness operates differently in the District and Supreme Courts.
A criminal act can be justified if the act is necessary to prevent a foreseeable and greater harm than the harm created by your criminal act. For example, trespassing onto a property is acceptable if you are trying to save someone from drowning in a pool. The criminal act committed must not be out of proportion to the imminent peril.
Parliament’s recognition of a person’s right to life by enabling a person to use force to protect it is enshrined in Section 418 of the Crimes Act 1900 which states:
(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:
and the conduct is a reasonable response in the circumstances as he or she perceives them.
The final two lines of that section is of significant importance, because what if a person suffers from a mental illness that alters their ability to process their emotions, which are impacted by what they perceive through their senses?
During a trial for murder – the partial defence of extreme provocation
Even though some people have taken a life, they are not to blame completely. In cases where the accused was extremely provoked by the victim, Section 23 of the Crimes Act 1900 states:
(1) If, on the trial of a person for murder, it appears that the act causing death was in response to extreme provocation and, but for this section and the provocation, the jury would have found the accused guilty of murder, the jury is to acquit the accused of murder and find the accused guilty of manslaughter.
(2) An act is done in response to extreme provocation if and only if—
It must be noted however that the partial defence of extreme provocation exists only during a trial for murder.
Defence of lawful correction
Given the limited capacity for infants to understand reason and logic (by virtue of their age alone), the law recognizes that parents may require the ability to physically discipline their children. This statutory recognition is enshrined in Section 61AA of the Crimes Act 1900 which states:
(1) In criminal proceedings brought against a person arising out of the application of physical force to a child, it is a defence that the force was applied for the purpose of the punishment of the child, but only if—
(2) The application of physical force, unless that force could reasonably be considered trivial or negligible in all the circumstances, is not reasonable if the force is applied:
