When a child is charged with a criminal offence in Australia, the court does not immediately proceed on the assumption that the child understood what they did was wrong. The doctrine of doli incapax (Latin for "incapable of wrong") creates a legal presumption that children between the ages of 10 and 14 lack the capacity to form criminal intent. That presumption is rebuttable, but it shifts the burden squarely onto the prosecution. Understanding how it operates is essential for any family navigating the youth justice system.
The age brackets that matter
Australian criminal law draws a hard line at age 10. Children under 10 cannot be prosecuted at all. That absolute bar applies in every Australian jurisdiction and reflects a consensus that very young children simply cannot be held to account under the criminal law.
Children aged 10 to 14 sit in a different category. The law presumes they are doli incapax, meaning incapable of criminal guilt, but the prosecution can attempt to rebut that presumption. Once a child turns 14, the presumption no longer applies and the child is treated as an adult for the purposes of criminal capacity, though separate youth justice frameworks still govern how a matter is heard and sentenced.
What the prosecution must prove to rebut the presumption
Rebutting doli incapax requires more than proving the child committed the physical act. The prosecution must demonstrate, beyond reasonable doubt, that the child knew at the time of the offending that what they were doing was seriously wrong, not merely naughty or mischievous.
That is a demanding standard. Courts have consistently held that "seriously wrong" means morally and legally wrong in a meaningful sense, not simply prohibited. Evidence the prosecution might rely on includes:
- Admissions made by the child during police questioning that show awareness of wrongdoing.
- Attempts to conceal the offending, such as hiding evidence or lying to adults.
- Prior warnings from parents, teachers or authorities about the specific conduct.
- The nature of the offence itself, where the wrongfulness would be obvious to a child of similar age and background.
Each factor is weighed in context. A single piece of evidence rarely suffices on its own.
How courts assess the child's actual understanding
Courts don't apply a one-size-fits-all test. A child's age, maturity, education, intellectual capacity and background are all relevant. A 13-year-old with a cognitive disability is assessed differently from a 13-year-old with no such impairment, even if the conduct is identical.
Expert evidence from psychologists or psychiatrists is often called to assist the court. That evidence can address whether the child had the cognitive and emotional development to appreciate the seriousness of their actions. This is one reason why a fitness to stand trial hearing can sometimes intersect with doli incapax arguments, particularly where a child has a significant developmental condition.
Doli incapax and the right to silence
Children questioned by police have the same right to silence as adults, and exercising that right cannot be used to rebut doli incapax. The prosecution must establish knowledge of wrongdoing through positive evidence. Silence tells the court nothing about what the child understood. This is worth knowing because police questioning of young people often focuses on obtaining admissions, and those admissions can later become the primary basis for a rebuttal argument. Getting legal advice before any police interview is not just important, it's critical. Understanding the right to silence in Australia applies equally, and often more urgently, to young people in custody.
How the presumption plays out in practice
If the prosecution cannot rebut doli incapax, the charge fails regardless of whether the child committed the physical act. The child is acquitted on the basis of incapacity, not on the basis that they didn't do it.
Where the prosecution does rebut the presumption, the matter proceeds. The child is then dealt with under whichever youth justice framework applies in that jurisdiction. In New South Wales, that means the Children (Criminal Proceedings) Act 1987 (NSW) governs the proceedings, including where the matter is heard and how sentencing is approached. Courts retain a wide discretion in dealing with young offenders, and a finding that doli incapax was rebutted does not automatically lead to a punitive outcome.
The policy debate around the age of criminal responsibility
Australia's minimum age of criminal responsibility has attracted sustained criticism from legal and medical experts. The United Nations Committee on the Rights of the Child has recommended a minimum age of 14 across all jurisdictions. The Australian Law Reform Commission and various state law reform bodies have examined the issue, and several jurisdictions have moved or are considering moves to raise the minimum age from 10 to 12.
As at 2026, the age of criminal responsibility remains 10 in New South Wales, though the debate is ongoing. The doli incapax presumption fills part of the gap by providing a practical protection for children aged 10 to 13. It doesn't replace law reform, but it does mean that a child in that age range cannot be convicted without the prosecution meeting a genuinely high standard of proof about the child's moral understanding.
What families should do when a child is charged
If a child aged between 10 and 14 is charged with any offence, the first step is to get specialist legal advice before the child says anything to police. The doli incapax presumption is a live and significant issue in every such case, and the way the child conducts themselves from the moment of questioning can affect whether the presumption can be rebutted.
