Mental Health Commission
The Mental Health Commission (Commission) is the agency principally responsible for assisting the Minister for Mental Health (Minister) in the administration of the Mental Health Act 2014 and the Alcohol and Other Drugs Act 1974.
Statutory Review of the Mental Health Act 2014
As the agency principally responsible for assisting the Minister in administering the Act, we were tasked with conducting the Statutory Review of the Act, which began in 2021.
The Commission undertook a six-month public comment period, which opened on 13 August 2021 and closed on 31 January 2022, supported by the release of a Discussion Paper.
The Review concluded in early 2024 with the Review Report and Government Response tabled by the Minister in Parliament on 16 April 2024. All 54 recommendations about legislative amendments were accepted in principle by the State Government.
Next Steps
The Commission will begin planning for the development of legislation to make amendments to the Mental Health Act 2014, in response to the Review Report. This will include undertaking consideration of any implementation requirements and non-legislative system improvement measures that also formed part of the Review Report.
The Criminal Law (Mental Impairment) Act 2023 (CLMI)
The Criminal Law (Mental Impairment) Act 2023 (CLMI) received Royal Assent on 13 April 2023 and will be enacted on 1 September 2024. CLMI establishes new legal provisions for people who are unfit to stand trial or found not guilty by reason of mental impairment in the criminal justice system.
When CLMI commences, existing people (Supervised Persons ) under the existing Criminal Law (Mentally Impaired Accused) Act 1996 (CLMIA) will be transitioned to CLMI. These transitional proceedings managed by the Department of Justice will include individual case reviews by the Mental Impairment Review Tribunal (MIRT).
The purpose of CLMI is to:
- make provision in relation to criminal proceedings involving persons with mental impairment
- provide for special criminal proceedings for persons who are unfit to stand trial
- provide for the supervision of persons who, in special criminal proceedings, are found to have committed and offence
- provide for the supervision of persons acquitted on account of mental impairment; and to provide for the safe reintegration into the community of persons supervised under this Act
- repeal the Criminal Law (Mentally Impaired Accused) Act 1996 and the Criminal Law (Mentally Impaired Accused) Regulations 1997; and for related purposes.
The Commission is working collaboratively with a number of agencies to ensure that the community is advised and supported with the implementation of CLMI.
