Defence of Sudden or Extraordinary Emergency (Vic)

By James Stevens, Director and Solicitor, Go To Court Lawyers. Last reviewed 14 April 2026.

In Victoria, under section 322R of the Crimes Act 1958, a person who is facing criminal charges can rely on the legal defence of sudden and extraordinary emergency. This defence is applicable when the accused admits doing the physical acts that make up the offence but claims that they had a valid reason as they were acting in response to an emergency. This defence provides crucial protection for individuals who find themselves in unavoidable situations where breaking the law becomes necessary to prevent greater harm. Understanding this defence is essential for anyone facing criminal charges in Victoria, as it can mean the difference between a conviction and an acquittal. This page outlines the defence of sudden and extraordinary emergency in Victoria.

When will sudden and extraordinary emergency succeed?

The defence of sudden and extraordinary emergency is outlined in Victorian legislation and has been interpreted through Australian case law. Successfully raising this defence requires meeting specific legal criteria and demonstrating that the circumstances truly warranted the alleged criminal conduct.

Legislation

Section 322R of the Crimes Act 1958 only applies if the accused reasonably believed that:

• circumstances of sudden or extraordinary emergency existed; and
• their conduct was the only reasonable way to deal with the emergency; and
• the conduct was a reasonable response to the emergency.

The legislation emphasises that the accused's belief must be reasonable from an objective standpoint. This means the court will consider whether a reasonable person in the same circumstances would have formed the same belief about the emergency and the necessity of their actions.

Case law

The WA Supreme Court ruling of Counsel v Glynn [2017] WASC dealt with driving offences and the operation of the defence of sudden or extraordinary emergency. Banks-Smith J made the following points:

• The elapsed time between the offender becoming aware of the emergency and their response to it may be relevant in determining whether an emergency is sudden or extraordinary.
• An emergency that catches the accused off-guard and unexpectedly is considered 'sudden,' while an 'extraordinary emergency' is unexpected. However, the actions taken by the accused must be a reasonable response to the emergency. For instance, speeding to take a loved one to the hospital for a minor cut will not be excused based on emergency.

Victorian courts have also established that the defence requires a direct causal link between the emergency circumstances and the criminal conduct. The emergency must be imminent, and alternative lawful options must be genuinely unavailable or inadequate to address the situation.

When is the defence of sudden or extraordinary emergency available?

The defence of sudden and extraordinary emergency is available for all offences in Victoria. However, it is only available for murder, if the accused believes that the emergency involves a risk of death or really serious injury (Section 322R of the Crimes Act).

Factors for consideration

The nature of the alleged offence is a critical factor in determining whether this defence can or should be invoked. The test to satisfy this defence is challenging. In evaluating the likelihood of the defence succeeding, the following should be taken into account:

• The circumstances surrounding the alleged offence
• The events leading up to the alleged offence
• If the situation involved a medical emergency, any prior medical history and any previous medical advice given
• The offence in proportion to the gravity of the emergency.

Common scenarios

This defence commonly arises in cases involving traffic offences, such as dangerous driving to reach a hospital during a medical emergency, property damage while escaping immediate physical danger, or theft of necessities during natural disasters. The key is demonstrating that the criminal act was genuinely necessary and proportionate to the emergency faced.

Burden of proof

The defence must raise the defence of sudden and extraordinary emergency. The prosecution must then prove beyond a reasonable doubt that the offence did not occur in response to a sudden or extraordinary emergency, that the conduct was not the only reasonable way of dealing with the emergency, or that the accused's actions were not a reasonable response to the emergency.

This reverse onus means that once the defence is properly raised with sufficient evidence, the prosecution bears the heavy burden of disproving it. The defence team must present credible evidence supporting each element of the emergency defence, including expert testimony if relevant, witness statements, and documentation of the emergency circumstances.

Emergency or necessity?

The defence of emergency replaced the common law defence of necessity in Victoria under the Crimes Act 1958. This legislative reform aimed to provide clearer guidelines and more predictable outcomes for defendants facing emergency situations.

The defence of necessity applied when an accused person admitted committing an act but argued that doing so was necessary to avoid harm or to protect another person. When a court decided whether a person was acting out of necessity, it weighed the offence against the harm that needed to be avoided.

In New South Wales, the common law defence of necessity still exists and no defence of emergency has been legislated.

Practical application and strategic considerations

When considering whether to rely on the defence of sudden or extraordinary emergency, legal practitioners must carefully evaluate the strength of the evidence and the likelihood of success. The defence is not suitable for every case and requires thorough preparation.

Evidence requirements

Successfully mounting this defence typically requires comprehensive evidence gathering, including medical records for health emergencies, witness testimony about the circumstances, expert evidence on available alternatives, and documentation proving the immediacy of the threat or emergency situation.

Alternative defences

Legal practitioners should also consider whether other defences might be more appropriate, such as self-defence under section 322K of the Crimes Act 1958, duress, or mental impairment defences. Sometimes multiple defences can be run simultaneously, providing the accused with the best possible protection.

Limitations and exclusions

While the defence of sudden or extraordinary emergency is broadly available, certain limitations apply that defendants and their legal representatives must understand.

Proportionality requirement

The response must be proportionate to the emergency faced. Courts will carefully scrutinise whether the criminal act was truly necessary and whether the accused considered less harmful alternatives. A minor emergency cannot justify serious criminal conduct.

Self-created emergencies

Generally, individuals cannot rely on this defence if they deliberately or recklessly created the emergency situation themselves. However, each case is assessed on its individual merits, and the circumstances surrounding how the emergency arose will be carefully examined.

Frequently Asked Questions

Can I use the defence of sudden or extraordinary emergency for any criminal offence in Victoria?

Yes, the defence is available for all criminal offences in Victoria under section 322R of the Crimes Act 1958. However, for murder charges, the defence only applies if you reasonably believed the emergency involved a risk of death or really serious injury. The success of the defence will depend on whether your actions were a reasonable and proportionate response to the emergency circumstances.

What is the difference between a 'sudden' emergency and an 'extraordinary' emergency?

A 'sudden' emergency is one that catches you off-guard and occurs unexpectedly without warning. An 'extraordinary' emergency refers to circumstances that are unusual, exceptional, or outside normal experience. Both types must require immediate action, and the time between becoming aware of the emergency and responding to it may be relevant in determining whether the defence applies to your situation.

Do I need to prove the emergency defence, or does the prosecution need to disprove it?
