There is a common-law maxim that no man is to be brought into jeopardy for the same offence more than once. This maxim is captured by Section 17 of the Queensland Criminal Code 1899, which creates the defence of double jeopardy. That section reads:

“It is a defence to a charge of any offence to show that the accused person has already been tried, and convicted or acquitted upon an indictment on which the person might have been convicted of the offence with which the person is charged, or has already been acquitted upon indictment, or has already been convicted, of an offence of which the person might be convicted upon the indictment or complaint on which the person is charged.”

The legal doctrine of double jeopardy can be broken down into two concepts: Autrefois Acquit and Autrefois Convict. These concepts have different bases but are usually discussed in tandem.

Autrefois acquit

Roughly translated as “formerly acquitted”, the principle of autrefois acquit precludes a prosecuting authority from bringing a charge relating to an alleged offence that a person has already been acquitted on.

In Davern v Messel (1984), Gibbs CJ outlines the rationale behind the principle of autrefois acquit as follows:

“The purpose of the rule is of course to ensure fairness to the accused. It would obviously be oppressive and unfair if a prosecutor, disappointed with an acquittal, could secure a retrial of the accused person on the same evidence, perhaps before what the prosecutor ‘considered to be a more perspicacious jury or tougher judge’. It might not be quite so obvious that it would be unfair to put an accused upon his trial again if fresh evidence, cogent and conclusive of his guilt, came to light after his earlier acquittal, but in such a case the fact that an unscrupulous prosecutor might manufacture evidence to fill the gaps disclosed at the first trial, and the burden that would in any case be placed on an accused who was called upon repeatedly to defend himself, provide good reasons for what is undoubtedly the law, that in such a case also the acquittal is final.

When the prosecution seeks to appeal from an acquittal, the rule against double jeopardy has an indirect application… The view has been taken that the common law rule against double jeopardy would be infringed by allowing an appeal from an acquittal, since the rule requires than an acquittal be treated as final.”

Autrefois convict

The principle of autrefois convict (formerly convicted) precludes the Crown from re-asserting an allegation on which an accused has already been convicted, and a court has passed sentence.

Exceptions to double jeopardy

The Criminal Code (Double Jeopardy) Amendment Act, which was introduced in 2007, created two exceptions to the double jeopardy rule.

The first exception allows the court to make an order that a person acquitted of murder be retried for the offence if fresh and compelling evidence is brought forth after the acquittal and it is in the interests of justice for the order to be made. This provision also allows for a person to be tried for murder if they were previously charged and acquitted of a lesser offence.

The second exception allows for a person to be retried if their acquittal is tainted by the commission of an administration of justice offence, such as perjury or witness tampering. This exception only applies where a person has been charged with offences carrying a maximum penalty of 25 years imprisonment or more and where the person likely would have been convicted but for the administration of justice offence.

These exceptions were introduced based on the principles that a criminal justice system ought to correct errors, and that an offender should not evade punishment for serious crimes.

DPP v TAL

In 2018, an application was brought by the Crown to retry a man who had been acquitted of murder in 1988 on the basis that sophisticated DNA testing became available only after his acquittal. DNA found on the deceased’s pillow had been found to match the profile of the accused after his acquittal.

The court refused the application, stating that the scientists who gave evidence in the 1988 trial were not available to testify. It stated,  “DNA matching is powerful evidence because, if there has been scientific integrity in the process that leads to obtaining a profile, it is almost incontrovertible… The inability of a defendant to test that integrity means that there cannot be a fair trial.” (DPP v TAL, [2019] QCA 279) The retrial of the accused was therefore not in the interests of justice.

Frequently Asked Questions

What is the difference between Autrefois Acquit and Autrefois Convict in Queensland double jeopardy law?

Autrefois Acquit means 'formerly acquitted' and prevents prosecution from charging someone for an offence they've already been acquitted of. Autrefois Convict means 'formerly convicted' and prevents re-prosecution for an offence someone has already been convicted of. Both principles under Section 17 of the Queensland Criminal Code 1899 ensure no person faces jeopardy for the same offence twice, protecting against unfair multiple prosecutions.

Does Queensland's double jeopardy defence apply to all criminal charges or only indictable offences?

Queensland's double jeopardy defence under Section 17 of the Criminal Code 1899 applies broadly to criminal charges, covering both indictable offences and summary offences. The section specifically mentions both 'indictment' and 'complaint', indicating it protects against re-prosecution whether the previous trial was in the District/Supreme Court (indictment) or Magistrates Court (complaint), ensuring comprehensive protection across Queensland's criminal justice system.

How much does it cost to get legal advice about a double jeopardy defence in Queensland?

Go To Court Lawyers offers a fixed-fee consultation for $295 to discuss your double jeopardy defence in Queensland. This consultation allows you to understand whether Section 17 of the Criminal Code 1899 applies to your situation, assess the strength of your defence, and get expert advice on how previous acquittals or convictions might protect you from re-prosecution for the same or related criminal charges.

How can a criminal lawyer help me with a double jeopardy defence in Queensland?

A criminal lawyer can analyse your previous charges and outcomes to determine if double jeopardy applies under Section 17 of the Queensland Criminal Code. They'll examine whether current charges relate to offences you've already been tried for, prepare legal arguments citing relevant case law like Davern v Messel, file appropriate defence applications, and represent you in court to ensure the prosecution cannot proceed with charges that breach double jeopardy principles.

Is there a time limit to raise a double jeopardy defence in Queensland criminal proceedings?

A double jeopardy defence should be raised as early as possible in Queensland criminal proceedings, ideally at the first court appearance or when entering your plea. While there's no strict statutory time limit, courts prefer defences like double jeopardy to be raised promptly to avoid delays and ensure efficient case management. Delaying this defence could complicate proceedings and may require court permission to raise it later in the process.
