Criminal Damage – Elements & Defences (Crimes Act s.197(1))
Statutory Source
Offence created by the Crimes Act, s.197(1). This section specifically outlines the criteria that must be met for a charge of property destruction or damage to be laid and prosecuted.
Elements the Prosecution Must Prove (ALL 4 Required)
1. Destruction or Damage of Property
The accused must have destroyed or damaged something that legally counts as “property.”
This includes any act that renders property unusable, impaired, or diminished in value.
Damage does not need to be permanent; temporary impairment can suffice.
“Property” = real or personal property, expressly including money. This broad definition covers land, buildings, vehicles, goods, and all forms of currency.
Examples: Graffiti on a wall, breaking a window, cutting a fence, or disabling a computer system.
2. Property Belonged to Another
“Belongs to another” when someone other than the accused has:
Control over the property: This refers to physical possession or the right to dictate its use.
A proprietary interest: This includes legal or equitable ownership, such as part-ownership or beneficial interest in a trust.
A charge over it: This means a security interest like a mortgage or a lien, where the property serves as collateral for a debt.
Examples:
Interests of a mortgagee: The bank holding a mortgage on a house still has a proprietary interest in the property, even if the homeowner is the primary occupant.
Assets held in trust: Property managed by a trustee for the benefit of another person (the beneficiary).
Corporate property: Assets owned by a company, distinct from its individual employees or directors.
Property can have multiple owners; prosecution only needs to show that at least one person (not the accused) had ownership or one of the above interests.
3. Intent or Knowledge
The accused must either:
Act with the purpose of damaging/destroying the property: This means the intention to cause the specific damage was the accused's direct aim or objective (direct intent).
OR
Know their conduct is likely to cause such damage/destruction: This refers to recklessness, where the accused foresees the probability or real possibility of damage occurring from their actions but proceeds anyway, indifferent to the risk.
It is not necessary for the accused to have intended the extent of the damage that actually occurred, only that some damage was intended or foreseen as likely.
4. Absence of Lawful Excuse
Prosecution must prove the accused did not have a lawful justification for their actions.
This element acts as a safeguard, ensuring that actions taken under legitimate circumstances are not criminalized.
Possible excuses the prosecution must negate:
Belief that the property belonged to them: A genuine (though possibly mistaken) belief by the accused that they were the sole owner of the property and thus had a right to damage it. This defence does not require the belief to be reasonable, only genuinely held.
Belief they had a legitimate right or interest to damage/destroy it: This covers situations where the accused believed they had permission (express or implied) from the owner, or a legal right (e.g., specific contractual terms or legal privilege) to act as they did.
The burden is on the prosecution to disprove any such lawful excuse raised by the defence beyond a reasonable doubt.
Defences & Excuses (Accused May Raise)
Self-Defence (Common Law): If the accused reasonably believed the damage was necessary to protect themselves or another person from an imminent threat of unlawful force, and their actions were a reasonable response in the circumstances, conviction should not follow. This defence focuses on the necessity of the act to prevent harm.
Claim of Right / Lawful Excuse (further details):
Accused may argue:
They genuinely (and reasonably) believed the property was theirs: This defence is often raised in disputes over ownership, where the accused genuinely believes they are entitled to the property being damaged.
They held a recognised right or interest allowing the act: This includes situations where the accused believed they had express or implied consent from the owner, or a legal authority (e.g., police officer lawfully disarming a dangerous device, or a person abating a nuisance on their property).
The test is subjective as to the belief, but objective as to whether that belief, if true, would constitute a lawful excuse.
Practical/Legal Significance
Burden of proof: The Prosecution must establish every element outlined above beyond a reasonable doubt. This is a high standard and means there must be no reasonable doubt left in the mind of the trier of fact (judge or jury) that the accused committed the offence.
Any credible evidence suggesting a lawful excuse shifts focus back to the prosecution to disprove that excuse beyond a reasonable doubt. The accused does not need to prove their excuse, only to raise it as a live issue for the prosecution to negate.
Recognising multiple ownership is crucial—damage to jointly-owned items can still satisfy the “belonged to another” requirement. This prevents individuals from damaging shared property and escaping liability by claiming partial ownership.
The severity of the penalty for this offence can vary significantly based on the value of the damage caused and the specific intent of the accused.
