Doli Incapax Explained: When Children Cannot Be Held Criminally Responsible

In Australian criminal law, children under a certain age may not be legally responsible for criminal behaviour under the principle of doli incapax.

The doctrine recognises that children do not develop emotional maturity, judgment and moral understanding at the same rate as adults. Because of this, the law treats juvenile offenders differently from adult offenders under NSW legislation.

If your child has been accused of an offence, it is important to obtain advice from an experienced juvenile crime lawyer or criminal defence lawyer as early as possible.

What Does Doli Incapax Mean?

Doli incapax is a Latin term meaning “incapable of crime”.

Under Australian law:

• children under the age of 10 cannot be held criminally responsible for offences;
• children aged between 10 and 14 are presumed incapable of forming criminal intent unless the prosecution proves otherwise.

The principle exists because the law recognises that young children may not fully understand the difference between serious wrongdoing and childish misbehaviour.

The concept of criminal responsibility for children is recognised throughout Australian criminal law and has been discussed extensively by the Judicial Commission of NSW.

The Age of Criminal Responsibility in Australia

In most Australian states and territories, a juvenile is considered a person aged between 10 and 18. In Queensland, the age limit is generally 17.

Children under 10 are considered incapable of committing a criminal offence because they are unable to form the required criminal intention, known as mens rea.

The law assumes children below this age do not yet possess sufficient understanding of:

• right and wrong,
• consequences of their behaviour,
• and the seriousness of criminal conduct.

How Doli Incapax Applies to Children Aged 10–14

For children aged between 10 and 14, the presumption of doli incapax still applies.

However, prosecutors may attempt to rebut the presumption by proving the child understood that their conduct was seriously wrong rather than merely naughty or mischievous.

This means a child in this age group can still be convicted if the prosecution successfully proves:

• the child understood the nature of the conduct,
• and appreciated it was seriously wrong according to ordinary community standards.

Australian courts recognise that children mature at different rates, which is why the law assesses criminal responsibility individually during this age range.

If police are investigating a child for an offence, it is important to understand their rights during police questioning of minors and Children’s Court proceedings.

Why Are Juvenile Offenders Treated Differently?

Juvenile offending differs significantly from adult criminal behaviour.

Research consistently shows children:

• are more impulsive,
• are heavily influenced by peers,
• take greater risks,
• and often lack the emotional maturity of adults.

Young people may understand that an act is “wrong” in a basic sense while still lacking the judgment and psychological development required to fully appreciate the consequences.

Studies from the Australian Institute of Criminology show juveniles commonly engage in:

• vandalism,
• shoplifting,
• fare evasion,
• graffiti,
• property offences,
• and opportunistic behaviour.

Serious violent offending is far less common among children than adults.

The Influence of Peer Pressure and Development

Children and adolescents are especially vulnerable to peer influence.

Youth justice experts have long argued that children may participate in antisocial behaviour simply to maintain friendships or social acceptance.

Because the brain is still developing during adolescence, young people are more likely to:

• act impulsively,
• seek approval from peers,
• and underestimate long-term consequences.

For this reason, the law prioritises rehabilitation and intervention over punishment.

This is also reflected in the way courts approach sentencing for minors and juvenile bail applications.

Do Most Juvenile Offenders Continue Criminal Behaviour?

Research indicates most young offenders do not become lifelong criminals.

Juvenile offending often peaks during adolescence and declines as individuals mature into adulthood.

According to data published by BOCSAR NSW and the Australian Institute of Criminology, rehabilitation and diversion programs are often more effective for children than punitive measures.

This is one reason why the Australian justice system focuses heavily on:

• rehabilitation,
• diversion programs,
• counselling,
• education,
• and community-based interventions.

The aim is to reduce reoffending while helping children reintegrate into society.

Children’s Courts in NSW

In New South Wales, specialised courts deal with criminal matters involving juveniles.

The Children’s Court of NSW is designed to address youth offending in a way that reflects:

• the child’s age,
• level of maturity,
• personal circumstances,
• and rehabilitation prospects.

Some of the busiest Children’s Courts in Sydney are located in:

• Parramatta,
• Campbelltown,
• and Bidura.
