R v Briggs

[2012] NSWSC 977

Sexual offencesHomicide
CRIMINAL LAW PROCEDURE FITNESS TO PLEAD OR BE TRIED CHARGE OF MURDER MILD INTELLECTUAL DISABILITY

Citation: R v Briggs [2012] NSWSC 977
Court: Supreme Court of New South Wales
Date: 21 August 2012
Judge(s): Latham J

Background

The accused faced trial in the Tamworth Supreme Court on charges of murder and sexual intercourse with a child under ten years of age. The charges arose from events on 5 September 2010, when the accused was the sole adult carer for two young children, one of whom was taken to hospital with severe head trauma, genital bruising, and anal lacerations, and who died the following day. The accused was identified as the child's principal carer during the relevant period.

Before the trial commenced, counsel for the accused raised a question about his fitness to be tried. The trial date was vacated and a fitness hearing was convened, during which four specialists examined the accused: two forensic psychiatrists (Dr Kavanagh and Dr Furst) and two clinical neuropsychologists (Dr Hepner and Dr Stewart).

The fitness inquiry proceeded under the Mental Health (Forensic Provisions) Act 1990, which requires the court to conduct the assessment in a non-adversarial manner and to determine fitness on the balance of probabilities, with no formal onus on either party.

  • Whether the accused met the fitness criteria established in R v Presser [1958] VR 45, as approved by the High Court
  • Specifically, whether the accused could understand the nature of the charges, appreciate the significance of his own role in proceedings, follow the course of the trial, understand the substantial effect of evidence against him, and give meaningful instructions to counsel

Decision

The court applied the Presser criteria, which require an accused to understand the charges, be capable of pleading, understand the nature of the proceedings generally, follow what occurs in court, appreciate the substantial effect of evidence against them, and instruct counsel as to their version of events.

The expert opinions were divided. Dr Kavanagh (forensic psychiatrist) initially concluded the accused was fit to stand trial, noting that he could identify key participants and articulate their roles in general terms. However, she acknowledged significant doubts about his ability to follow proceedings, concentrate throughout a trial, challenge witnesses, and give adequate instructions. Dr Furst, after further examination informed by psychometric test results, concluded the accused was not fit. Dr Stewart and Dr Hepner, the neuropsychologists, assessed the accused as functioning within the extremely low range of general intellectual ability, with a full-scale IQ in the first percentile. Both concluded he did not meet all of the Presser criteria.

Latham J found, on the balance of probabilities, that the accused was not fit to stand trial. The decisive factor was the accused's very limited capacity to process conceptual information, which affected his ability to appreciate the nature of the evidence against him, follow the course of the proceedings, and give meaningful instructions to counsel. To the extent Dr Kavanagh maintained a contrary view, Latham J found this was difficult to reconcile with her own observations of the accused's limited understanding of his role in the trial.

Orders Made

  • The accused was directed to be referred to the Mental Health Review Tribunal for assessment at the earliest opportunity.
  • The expert reports tendered in the inquiry were to be forwarded to the Tribunal for its consideration.

Key Takeaways

  • The Supreme Court confirmed that fitness to stand trial is assessed on the balance of probabilities under the Mental Health (Forensic Provisions) Act 1990, with neither party bearing any onus.
  • The Presser criteria, long approved by the High Court, set a minimum functional threshold: an accused must be capable of understanding the proceedings in a general sense, appreciating the effect of evidence against them, and giving meaningful instructions to counsel. Technical legal knowledge is not required.
  • Psychometric testing results carried significant weight in the inquiry, with neuropsychological evidence helping to resolve initial uncertainty in the psychiatric opinions.
  • Where an expert's overall conclusion of fitness sits in tension with their own recorded observations about an accused's limitations, a court may decline to follow that conclusion.
  • A finding of unfitness does not determine guilt. It triggers referral to the Mental Health Review Tribunal for further assessment rather than discharging the accused from the proceedings.
