Introduction, definitions and key legislation: Mental illness


Mental illness and psychiatric disability

Psychiatric disability can refer to a range of mental illnesses and mental disorders that are distinct from other cognitive impairments and intellectual disabilities. For the purposes of the Mental Health Act 2014 (Vic), however, “mental illness” is defined, as “a medical condition that is characterised by a significant disturbance of thought, mood, perception or memory” (s 4(1)).

This definition is unchanged from the Mental Health Act 1986 (Vic), however the 2014 Act makes some subtle changes (marked thus “*” in the list below) to the list of criteria that cannot of themselves be indicative of mental illness:

expressing, refusing or failing to express a particular political or religious opinion or belief or a particular philosophy;

expressing, refusing or failing to express a particular sexual preference, gender identity* or sexual orientation;

engaging, refusing or failing to engage in a particular political or religious activity;

engaging in sexual promiscuity, or illegal or immoral conduct;

engaging in antisocial behaviour;

being intellectually disabled;

using drugs or consuming alcohol, although the serious temporary or permanent physiological, biochemical or psychological effects of their use may be regarded as an indication the person has mental illness;

having a particular economic or social status or being a member of a particular cultural or racial group;

having previously been involved in family conflict*; and

having previously been treated for mental illness.*

Treatment and detention of people with intellectual disabilities is covered by the Disability Act 2006 (Vic), not by mental health legislation (see Intellectual disability).

Mental Health Act 2014

The Mental Health Act 2014 (Vic) (“MHA 2014”) came into force on 1 July 2014. It repeals and replaces the Mental Health Act 1986 (Vic) (“MHA 1986”) and considerably changes the legal framework for the assessment and treatment of people with a mental illness in Victoria, especially compulsory assessment and treatment. MHA 2014 articulates a more human rights-promoting approach to assessment and treatment in mental health services than previously, through minimising the use and duration of compulsory treatment, establishing a recovery oriented framework for treatment, increasing safeguards and protection of the rights of people receiving compulsory treatment and improved oversight.

New terminology

Terminology in MHA 2014 has also changed. For example, “involuntary” treatment is now referred to as “compulsory” treatment. Likewise “involuntary” patient has become “compulsory” patient. The term “designated mental health services”, replaces “area mental health services”, as having the authority to provide compulsory mental health treatment and – in the case of a hospital – detention in some cases. The Mental Health Tribunal (MHT) is now the independent statutory tribunal providing the safeguard for the making of compulsory treatment orders, with additional powers and functions compared with its predecessor, the Mental Health Review Board (MHRB). There are also changes to the types, names and criteria for compulsory treatment orders.

Key objectives and principles

The second reading speech on the introduction of the new law makes it clear that the government intends the new law to minimise compulsory mental health treatment, and to ensure that the person with the mental illness is put at the centre of decision-making and provided with support to “make or participate in decisions about their assessment, treatment and recovery”. This fundamental shift in the way mental health services are provided is consistent with recovery-oriented practice. It is also reflected in the objectives of the MHA 2014, outlined at section 10 which include:

assessment of persons who appear to have, and the treatment of persons who have mental illness;

assessment and treatment in the least restrictive way possible with the least possible restrictions on human rights and human dignity;

protection of the rights of persons receiving assessment and treatment, and ensuring they are informed of their rights;

enabling and supporting the persons to make, or participate in, decisions about their assessment, treatment and recovery, and exercise their rights;

oversight and safeguards for assessment and treatment;

promoting recovery;

recognition of the role of carers in a person’s assessment, treatment and recovery.

Recovery, as the second reading speech states, “is about maximising individual choice, autonomy, opportunity and wellbeing during a person’s life and accordingly is a self-defined process that is highly individual”.

MHA 2014 also establishes a more comprehensive and rights-promoting set of mental health principles at section 11, to which mental health service providers (MHSPs) must have regard when providing mental health services, and which must be applied by anyone who performs any duty or function or exercises any power under the MHA 2014. The principles include:

providing the least restrictive assessment and treatment, with voluntary assessment and treatment preferred;

providing mental health services that aim for the best possible therapeutic outcomes, promote recovery and full community participation;

involving and supporting the person to make or participate in all decisions about their assessment, treatment and recovery, and respecting their views and preferences;

allowing the person to make decisions involving risk;

respecting and promoting their rights, dignity and autonomy;

recognising and responding to the person’s individual needs, including their medical and other health needs (e.g. alcohol and drug problems), their cultural and linguistic needs, their Aboriginality, their communication needs, and their needs in regards to their age, religion, gender and sexual identity;

promoting the best interests of children and young people, including separate services from adults whenever possible, and protection of their needs, wellbeing and safety;

involving carers (including children who are carers) in decisions about assessment, treatment and recovery whenever possible, and recognising, respecting and supporting their role.

In addition, section 8 requires that any advice, notification or information given to a patient under the MHA 2014 is explained to the maximum extent possible in the language, mode of communication and terms which they are most likely to understand and that, whenever reasonable, such information is given both orally and in writing.

The MHA 2014 also enshrines and gives effect to the fundamental principle that a person is presumed to have capacity to give informed consent to treatment, and can make their own decisions (s 70(2)). Only where there is evidence the person does not have capacity to consent, should this presumption be displaced. The presumption of capacity and definitions of capacity, informed consent and other capacity principles are outlined below.
