Mental health and cognitive impairment in criminal cases
If you live with a mental health condition or a cognitive impairment, the law gives the court other options. In the Local Court, a section 14 application asks the Local Court judge to dismiss the charge and connect you with treatment or support instead of proceeding to a plea and sentence. John holds a Master of Forensic Mental Health (with Excellence) from UNSW and has been a member of the Mental Health Review Tribunal of NSW since 2021.
- What law applies?
- The Mental Health and Cognitive Impairment Forensic Provisions Act 2020 (NSW), in force since 27 March 2021.
- What did section 14 replace?
- Section 32 of the old Mental Health (Forensic Provisions) Act 1990.
- What counts as cognitive impairment?
- An ongoing impairment in adaptive functioning and in comprehension, reasoning, judgment, learning or memory. It can come from conditions such as intellectual disability, borderline intellectual functioning, dementia, acquired brain injury, drug or alcohol related brain damage including fetal alcohol spectrum disorder, and autism spectrum disorder.
- Do I need to plead?
- No. A section 14 application can be made before a plea.

How a section 14 application works
- 1
Talk to John early
Tell him about any diagnosis, treatment or support you have. A diagnosis is helpful but not always essential to start.
- 2
Get the right report
John arranges or obtains a report from a psychiatrist, psychologist or treating doctor that addresses what the court needs to know.
- 3
Build a treatment or support plan
A plan shows the court who will support you and how, through your GP, a mental health service, NDIS supports or a treatment program.
- 4
The application
John argues why dealing with the matter this way is more appropriate than the usual criminal process.
- 5
The decision
If granted, the charge is dismissed, either unconditionally or on conditions such as following the treatment plan.
