Background

Mental health courts have operated in the USA for many years (McNiel & Binder, Reference McNiel and Binder2007; Wolff et al, Reference Wolff, Fabrikant and Belenko2011), the first one having been established in Florida in 1997 (Mikhail et al, Reference Mikhail, Akinkunmi and Poythress2001). Mental health courts also exist in Canada. However, to our knowledge, the process of the Queensland Mental Health Court (QMHC) model is unique worldwide. In Australia, individual states have legislative jurisdiction over a number of issues, including criminal justice and mental health systems. Legislation governing these areas is separate for each state. The current QMHC system was established as part of the Mental Health Act in 2000, the similar precursor Mental Health Tribunal having been established in 1985 (Queensland Government, 2014; State of Queensland, 2015). The recently updated Mental Health Act 2016 (which came into effect in March 2017) continued the QMHC, with some amendments (State of Queensland, 2018). The QMHC operates at the Supreme Court level and primarily determines cases where queries exist regarding insanity or unfitness for trial.

The Ministry of Justice in England and Wales completed a feasibility study to see whether a mental health court system, a diversionary model based at the magistrate level, would be worthwhile in terms of reducing reoffending rates and improving access to mental health services for offenders and defendants (Pakes et al, Reference Pakes, Winstone and Haskins2010). In this model, defendants, if guilty, would be held criminally responsible for their actions; therefore, it is not comparable to the QMHC model.

Structure and process

The QMHC is presided over by two Supreme Court Justices, who sit separately. Prior to the recent Mental Health Act, each judge was assisted by two independent forensic psychiatrists (Queensland Government, 2009, 2014), each of whom were selected from a panel of seven psychiatrists chosen by the court on the basis of their qualifications/experience and appointed for 3 year terms. The recent changes to the Mental Health Act mean that the assisting clinicians may be either psychiatrists or clinicians who have experience of caring for individuals with an intellectual disability. A psychiatrist cannot assist the court in cases where they have previously had any substantive involvement with the defendant.

At each sitting of the QMHC, there are up to four different sets of legal representatives present (representing the defendant, the Department of Health, the Director of Forensic Disability and the Director of Public Prosecutions). The defendant attends in person or via videolink.

The QMHC considers the following issues (Queensland Government, 2009; State of Queensland, 2015): whether the defendant was ‘of unsound mind’ at the time of the alleged offence; whether a diminished level of responsibility applies (in cases of alleged homicide); and fitness to plead/fitness for trial. It also hears appeals against Mental Health Review Tribunal findings.

Figure 1 outlines the process pathway – referrals can also be made by the Director of Public Prosecutions, by the Director of Forensic Disability, by a Court or by the Attorney General. A case can be referred to the QMHC if there are suspicions that the defendant is or was mentally ill and/or has an intellectual impairment such that, at the time of the alleged offence, they were ‘of unsound mind’ and/or that they are currently felt to be either temporarily or permanently unfit to plead, owing to mental illness and/or intellectual disability. A finding of ‘of unsound mind’ is made when the QMHC deems that someone, as a result of mental illness and/or intellectual impairment, was not able to understand what they were doing, could not control their actions, and/or did not know that they should not have committed the act or omission (based on the McNaughton rules). If that is the case, the defendant is acquitted and relevant treatment options are considered. It should be noted that the Queensland Mental Health Act states that: ‘unsound mind does not include a state of mind resulting, to any extent, from intentional intoxication or stupefaction alone or in combination with some other agent at or about the time of the alleged offence’ (State of Queensland, 2018).

If a defendant is deemed unfit to plead, the Court must then decide whether this unfitness is permanent. Where unfitness to plead is considered likely to be temporary, the Court is required to make either a forensic order or a treatment support order. Regular reviews of fitness to plead are conducted for a period of approximately 3 years (with the exception of cases involving offences carrying a potential sentence of life imprisonment, in which defendants are reviewed over a longer period). The Attorney General can discontinue or defer such review proceedings.

Once a referral is made to the QMHC, criminal court proceedings are suspended, with the exception of decisions regarding bail. If there is a dispute about whether the person committed the offence and there are no concerns about their fitness for trial, the QMHC should not consider the issues regarding soundness of mind, unless the dispute is considered attributable to mental illness, or the alleged offending involved any of the following: killing on provocation, diminished responsibility for murder, or killing for preservation in an abusive relationship (State of Queensland, 2018).

Table 1 highlights some of the key differences between the QMHC and the system in England and Wales.

Some differences between the QMHC and the current model in England and Wales

Advantages

• • The QMHC model is less adversarial and potentially more time- and cost-efficient. Each case is allocated a time slot, depending on complexity. A less complex case, with agreement between experts, may be processed by the court in 20 min, whereas serious contested cases (such as alleged homicide) may last for days. Table 2 outlines the productivity of the QMHC in recent years (Queensland Courts, 2017).

• • Defendants retain the right to a criminal trial. A mental health defence can still be presented if a case is subsequently heard in the criminal court setting. In such cases, the decision of the mental health court is not disclosed to the jury.

• • The frequent use of videolink and tele-evidence is a striking feature of the QMHC. Videolink allows professionals and defendants to be questioned without the delay associated with travel (Queensland is the second largest state in Australia and witnesses can be up to 1500 km from the Court). If there is consensus among the different parties regarding the finding in a case, evidence may not need to be heard.

• • Any psychiatric/clinical report relevant to the case, to which the referrer has access, is submitted at the point of referral. This applies even if any information therein will adversely affect the case.

• • The QMHC is allowed to consider a wide variety of materials as evidence, such as hearsay evidence and victim statements.

• • In most cases where the defendant receives a forensic order, the victim is informed about where the defendant is placed, when they are to be reviewed, and whether they are to receive community treatment. There is a specific victim support service.

Challenges

• • Critics may argue that the QMHC system allows the defendant to forego taking responsibility for their actions. Pragmatically, serious offences will usually result in forensic orders being made that will restrict the liberty of the individual for some years, or even permanently, if they remain unwell and a risk to the community. Each year in England and Wales, a small number of criminal cases result in a finding of not guilty by reason of insanity – 26 cases and 29 cases in 2015 and 2014, respectively (Freedom of Information request).

• • A significant dispute of the facts unrelated to mental illness results in no findings and the case being returned to the criminal court.

• • Financial constraints mean that the number of reports that can be commissioned by experts each month is limited; this can lead to some delays in cases being processed.
