MENTAL HEALTH FITNESS HEARING ACCUSED’S FITNESS TO STAND TRIAL

Citation: R v Gall [2024] NSWDC 315
Court: District Court of New South Wales
Date: 25 July 2024
Judge(s): Bennett SC ADCJ

Background

The accused, a 63-year-old Indigenous man, faced charges of dangerous driving occasioning death (under s 52A(2) of the Crimes Act 1900) and driving with a high-range prescribed concentration of alcohol. The charges arose from a collision on a rural unsealed road in western New South Wales on 19 May 2023, in which the accused's vehicle struck a quadbike ridden by a 52-year-old farmer, who died from his injuries. The accused's blood alcohol concentration was calculated at approximately 0.241 grams per 100 millilitres of blood at the time of the collision.

Before the accused was arraigned, a fitness hearing was conducted under Part 4 of the Mental Health and Cognitive Impairment Forensic Provisions Act 2020. The central concern was whether the accused's long history of alcohol misuse had caused cognitive impairment sufficient to render him unfit to stand trial.

Two neuropsychologists gave evidence: Dr Sally McSwiggan, retained by the accused, who concluded the accused was likely unfit; and Ms Lucienne Barhon, retained by the Crown, who concluded the accused was likely fit. The court heard their evidence concurrently.

Legal Issues

  • Whether the accused was fit to be tried under s 36(1) of the Mental Health and Cognitive Impairment Forensic Provisions Act 2020, having regard to the criteria set out in that provision.
  • Specifically, whether the accused's alcohol-induced mild neurocognitive disorder impaired his capacity to: understand the substantial effect of the evidence against him; instruct his legal representatives; and decide what defence to rely upon.
  • Whether appropriate modifications to the trial process could facilitate the accused's effective participation.

Decision

Issue 1: The fitness test and the expert evidence

The court applied the fitness criteria in s 36(1) of the Mental Health and Cognitive Impairment Forensic Provisions Act 2020, which draws on the principles in Reg v Presser (1958) VR 45 and Kesavarajah v The Queen [1994] HCA 41. Both experts agreed the accused suffered from alcohol-induced mild neurocognitive disorder, but disagreed on whether that condition rendered him unfit. The court preferred the opinion of Ms Barhon over that of Dr McSwiggan (at [303], [320]-[321]).

Issue 2: Reliability and weight of Dr McSwiggan's assessment

The court found Dr McSwiggan's assessment was materially limited. Her first consultation lasted only one hour via audio-visual link, and her supplementary consultation lasted just 20 minutes, also via AVL. The court found she accepted the accused's representations without sufficient further inquiry, and that her testing battery was considerably narrower than that administered by Ms Barhon (at [314]-[317]). Ms Barhon, by contrast, assessed the accused in person over four and a half hours using a broader range of psychometric tools, and the court found her approach enabled a more thorough exploration of his true capacity (at [203]-[204]).

Issue 3: Understanding of the blood alcohol concentration evidence

The court rejected the submission that the accused's refusal to accept the blood alcohol concentration evidence demonstrated an inability to reason caused by alcohol-related neurocognitive decline. The court found his changing explanations, offered across separate assessments, reflected a deliberate attempt to provide an alternative account of the evidence rather than an inability to understand it (at [272]-[275]). The court accepted Ms Barhon's view that a person's refusal to accept evidence implicating them does not equate to an inability to reason, particularly where doing so would conflict with an intended defence of not guilty (at [319]).

Issue 4: Fitness and trial modifications

The court found the accused capable of understanding the charges, recalling the relevant events, understanding the adverse effect of the evidence against him, and providing instructions to his legal representatives (at [322]). The court accepted that appropriate modifications, including the presence of a support person, regular breaks, and assistance from legal representatives during proceedings such as juror challenges, would facilitate the accused's participation (at [324]-[326]).

Orders Made

  • The accused is fit for trial.

Key Takeaways

  • The District Court confirmed that an accused's refusal to accept prosecution evidence, including compelling forensic evidence such as blood alcohol concentration results, does not of itself demonstrate an inability to reason for the purposes of the fitness test under s 36(1) of the Mental Health and Cognitive Impairment Forensic Provisions Act 2020. Where the refusal is explicable as a rational forensic decision consistent with an intended plea, it may be evidence of understanding rather than incapacity (at [319]).

  • The quality and comprehensiveness of a neuropsychological assessment materially affected the weight the court was prepared to give the resulting opinion. A one-hour AVL consultation with a limited testing battery was found insufficient to support robust conclusions about fitness, particularly where the assessor did not probe inconsistencies in the accused's representations (at [314]-[315]).

  • Both experts agreed on the diagnosis of alcohol-induced mild neurocognitive disorder, but disagreed on its forensic implications. The court's reasoning illustrates that a shared diagnosis does not predetermine the fitness outcome; the critical question is whether the impairment actually prevents the accused from meeting the minimum criteria in s 36(1).

  • Under s 44 of the Mental Health and Cognitive Impairment Forensic Provisions Act 2020, the court considered whether modifications to the trial process could facilitate participation. Practical measures, including a support person, regular breaks, and legal representative assistance with procedural steps, were accepted as sufficient to address the accused's challenges (at [324]-[326]).

  • A fitness determination is not a high bar. The court reiterated, consistent with Eastman v The Queen (2000) 203 CLR 1 and Roberts v R [2023] NSWCCA 187, that the test does not require perfection or complete understanding, and that a defence conducted in a manner contrary to the accused's best interests does not of itself establish unfitness (at [282]-[284]).
