What is Perjury in Australian Law? A Comprehensive Guide
Perjury is a serious offence against the administration of justice. It undermines the integrity of legal proceedings and can have significant consequences for individuals and the justice system as a whole. This guide provides a detailed explanation of perjury under Australian law, covering its key elements, the relevant legislation, how intent is proven, the different types of perjury, and the potential penalties.
Defining Perjury: Key Elements
At its core, perjury involves making a false statement under oath or affirmation in a judicial proceeding. However, not every false statement constitutes perjury. Several key elements must be present for a statement to be considered perjury under Australian law:
Oath or Affirmation: The statement must be made under a legally recognised oath or affirmation. This means the person making the statement has formally sworn or affirmed to tell the truth. The specific wording of the oath or affirmation may vary, but its purpose is to impress upon the individual the solemnity of the occasion and the importance of telling the truth.
Judicial Proceeding: The false statement must be made in a judicial proceeding. This includes court hearings, trials, tribunals, commissions of inquiry, and other formal legal proceedings where evidence is taken under oath or affirmation. The definition can extend to affidavits or statutory declarations made for the purpose of legal proceedings.
Materiality: The false statement must be material to the proceeding. This means the statement must be relevant and capable of influencing the outcome of the proceeding. A trivial or irrelevant false statement is unlikely to be considered perjury. For example, a minor discrepancy in someone's address might not be considered material, whereas a false statement about a key event in a case would likely be.
Falsity: The statement must be false. This seems obvious, but it's a crucial element. The prosecution must prove beyond a reasonable doubt that the statement made by the accused was untrue.
Knowledge and Belief: The person making the false statement must know that it is false and believe it to be untrue. This element of intent is critical and will be discussed in more detail later. Honest mistakes, even if incorrect, do not constitute perjury.
The Legal Framework: Commonwealth and State Laws
Perjury is a criminal offence in Australia, governed by both Commonwealth and State laws. The specific legislation and penalties vary slightly depending on the jurisdiction, but the core elements of the offence remain consistent.
Commonwealth Law: The primary Commonwealth legislation dealing with perjury is the Criminal Code Act 1995 (Cth). Section 135.1 of the Code deals with false testimony and carries significant penalties. This applies to perjury committed in federal courts or in relation to Commonwealth matters.
State and Territory Laws: Each State and Territory also has its own legislation dealing with perjury. For example, in New South Wales, perjury is covered under the Crimes Act 1900 (NSW). Similar legislation exists in Victoria, Queensland, South Australia, Western Australia, Tasmania, the Australian Capital Territory, and the Northern Territory. These laws generally apply to perjury committed in state courts or in relation to state matters. It's important to consult the specific legislation of the relevant jurisdiction to determine the exact provisions and penalties.

Overlap and Interaction
In some cases, there may be overlap between Commonwealth and State laws regarding perjury. The determination of which law applies depends on the specific circumstances of the case and the jurisdiction in which the perjury was committed. Generally, if the perjury relates to a Commonwealth matter, the Commonwealth law will apply. If it relates to a State matter, the State law will apply.

Intent and Knowledge: Proving Perjury
One of the most challenging aspects of prosecuting perjury is proving the element of intent. The prosecution must demonstrate beyond a reasonable doubt that the person making the false statement knew it was false and believed it to be untrue. This requires evidence of the person's state of mind at the time the statement was made.
Evidence of Intent
Several types of evidence may be used to prove intent, including:
Direct Evidence: This is the most straightforward type of evidence and includes statements made by the accused admitting they knew the statement was false. However, direct evidence is often rare in perjury cases.
Circumstantial Evidence: This is more common and involves using indirect evidence to infer the accused's state of mind. Examples of circumstantial evidence include:
Evidence that the accused had prior knowledge of the true facts.
Evidence that the accused had a motive to lie.
Evidence that the accused's statement was inconsistent with other evidence in the case.
Evidence of the accused's demeanour while giving the false statement.
The Burden of Proof
The burden of proof rests on the prosecution to prove all elements of perjury, including intent, beyond a reasonable doubt. This is a high standard of proof, and the defence may argue that the accused made an honest mistake or genuinely believed the statement to be true, even if it was ultimately false. The court will carefully consider all the evidence before making a determination on the issue of intent.

Types of Perjury: False Statements and Omissions
Perjury can take different forms, including both false statements and omissions. While actively making a false statement is the most commonly understood form of perjury, deliberately omitting information can also constitute the offence.
False Statements: This involves making a statement that is untrue and known to be untrue by the person making it. The statement can be oral or written and must be made under oath or affirmation in a judicial proceeding.
Omissions: In some circumstances, deliberately omitting information can also constitute perjury. This typically occurs when a person has a legal duty to disclose certain information and knowingly fails to do so under oath or affirmation. For example, if a witness is asked a direct question and deliberately fails to provide a complete answer, knowing that the omission makes their overall testimony misleading, this could be considered perjury. The key is the intent to deceive through the omission.
Penalties for Perjury in Australia
The penalties for perjury in Australia are significant and reflect the seriousness of the offence. The specific penalties vary depending on the jurisdiction and the circumstances of the case, but they generally include imprisonment and/or fines.
Commonwealth Penalties: Under the Criminal Code Act 1995 (Cth), the maximum penalty for perjury is imprisonment for up to 5 years. In some cases, where the perjury is particularly serious, the penalty may be even higher.
State and Territory Penalties: The penalties for perjury under State and Territory laws are generally similar to those under Commonwealth law. For example, in New South Wales, the maximum penalty for perjury under the Crimes Act 1900* (NSW) is imprisonment for 10 years. Other states have similar penalties. The severity of the penalty imposed will depend on factors such as the materiality of the false statement, the impact of the perjury on the outcome of the proceeding, and the accused's prior criminal history.
In addition to criminal penalties, a person convicted of perjury may also face other consequences, such as damage to their reputation and difficulty finding employment. Perjury can also have serious implications for the outcome of the legal proceeding in which it was committed, potentially leading to wrongful convictions or acquittals. It is a serious offence that undermines the foundation of the justice system. If you require legal guidance, our services can provide assistance in understanding your rights and obligations.
