Mental Health Diversion in Criminal Law
(NSW & Commonwealth Offences)

What Is Mental Health Diversion?

Mental health diversion is a legal process that allows a person charged with a criminal offence to be diverted away from the criminal justice system and into mental health treatment or support programs.

If you’re charged with a criminal offence in New South Wales or under Commonwealth law and suffer from a mental health condition or cognitive impairment, you may be eligible for a mental health diversion application under section 14 (NSW) or section 20BQ (Commonwealth).

These diversionary options focus on treatment and rehabilitation, not punishment, helping individuals address underlying mental health issues while avoiding a criminal conviction.


If you or someone you know is facing criminal charges and suffers from a mental health or cognitive impairment, it’s important to get expert legal advice early.

Section 14 Applications – NSW Mental Health Diversion

In New South Wales, mental health diversion is governed by section 14 of the Mental Health and Cognitive Impairment Forensic Provisions Act 2020 (NSW).

A section 14 application allows a person charged with a criminal or traffic offence to have their matter dismissed if the court is satisfied that:

  • They are suffering from a mental health impairment or cognitive impairment, and
  • It is more appropriate to deal with them under section 14 than through normal criminal proceedings.

If successful, the court can dismiss the charge outright or impose conditions for up to 12 months, such as:

  • Attending treatment or counselling,
  • Taking prescribed medication,
  • Engaging with a psychologist or psychiatrist, or
  • Avoiding drugs, alcohol, or certain places.

At the end of the conditional period, if the person complies, the matter is considered finalised without a criminal conviction.

Section 20BQ Applications – Commonwealth Offences

When you’re charged with a Commonwealth offence, such as social security fraud, child exploitation material, telecommunications offences, or importation offences, the NSW diversion laws (like section 14) don’t apply.

Instead, the relevant provision is section 20BQ of the Crimes Act 1914 (Cth).

Under section 20BQ, the court can:

  • Dismiss the charge, and
  • Discharge the person into the care of a responsible person (such as a doctor, psychologist, or family member),
    with or without conditions related to treatment or supervision.

There is a slight difference in the test, which is that the accused “is” at the time of the application, suffering from a mental illness, rather than suffering from one at the time of the offence, or any other time.

Like section 14, this process focuses on rehabilitation rather than punishment, ensuring the person receives appropriate medical care and support instead of a criminal conviction.

From Section 32 to Section 14

Prior to 2021, these applications were made under section 32 of the Mental Health (Forensic Provisions) Act 1990 (NSW).


Section 14 replaced section 32, modernising the legislation and expanding it to include both mental health and cognitive impairments.

Although the wording changed, the purpose remains the same — to provide people with mental health conditions a pathway out of the criminal justice system and into care.

If you’ve heard lawyers or magistrates refer to an old “section 32 application”, they are now referring to what is known as a section 14 application.

Benefits of a Mental Health Diversion Application

A successful section 14 or section 20BQ application can:

  • Prevent a criminal conviction from being recorded,
  • Enable access to appropriate treatment and mental health support,
  • Reduce the risk of reoffending, and
  • Support long-term recovery and rehabilitation.

For many clients, this process offers a second chance to address mental health issues in a therapeutic rather than punitive environment.
