The Court's task on sentencing
The agreed facts
Dr Chew's August 2015 report 1. Dr Chew's review of Mr Poynton's earlier medical records noted entries in 2011 recording that he was suffering psychotic paranoia and auditory hallucinations; 2. Mr Poynton had been treated as an involuntary patient under the Mental Health Act 2007 (NSW) in 2013, at a time when he was suffering suicidal intent and was diagnosed to be suffering a drug induced psychosis and an evolving major psychotic illness. He was admitted to the psychiatric unit from 1 to 15 July, when he was discharged on a Community Treatment Order. 3. In custody Mr Poynton's psychosis had been noted consistently and the psychiatrist Dr Jones had diagnosed him to be suffering "likely chronic mental illness complicated by ICE". 4. In December 2014 the psychiatrist Dr Nguy diagnosed him with "Drug Induced psychosis (?Schizophrenia)". 5. Dr Chew also diagnosed Schizophrenia with current active (symptoms), psychotic symptoms and Polysubstance Dependence, with the main substance of concern being methamphetamine (ICE), having a history of documented psychotic symptoms which had persisted many months after the cessation of methamphetamines. He also noted that Mr Poynton had a family history of mental illness. 6. Dr Chew's opinion was that Mr Poynton was then unfit to be tried.
Dr O'Dea's February 2016 report 1. Dr O'Dea considered that Mr Poynton presented as "acutely psychotic", with auditory hallucinations to which he was actively responding; paranoid delusions, including regarding prisoner officers and court officials; acute agitation and distress; abnormal affect, poor attention and concentration; and problems with insight and judgment. He considered that Mr Poynton's schizophrenic illness had yet to come under adequate control. 2. Dr O'Dea noted that Mr Poynton's illness was complicated by Polysubstance Use Disorder, in particular Amphetamine and Alcohol Use Disorder and that despite ongoing psychiatric treatment for up to 10 months and reported abstinence from illicit substances, at least over the majority of that time, he still presented as acutely psychotic. 3. Dr O'Dea also considered that Mr Poynton was unfit to be tried and that due to the apparent nature and severity of his schizophrenia and his limited response to treatment, that Mr Poynton should be admitted to an appropriate secure psychiatric facility under the Mental Health (Forensic Provisions) Act 1999 (NSW) for intensive psychiatric assessment and treatment, which might bring his illness under control.
Dr Chew's March 2016 report 1. Dr Chew noted 2015 records which noted an increase in voices and Mr Poynton believing a small lump on his bicep was a chip inserted to listen to him talk. In January 2016 Dr White, a treating psychiatrist, had noted that while there had been an improvement in the voices, they persisted. 2. Dr Chew considered that Mr Poynton's primary psychiatric issue remained Schizophrenia and that he displayed ongoing psychotic symptoms despite high doses of antipsychotic medication, although they had improved since July 2015. 3. Mr Poynton's significant substance misuse disorder was currently in remission, in a controlled environment, but despite some improvement in his mental state, Mr Poynton remained on balance unfit. The degree of his delusions involving officers and the court then rendered him unable to meaningfully understand the process, instruct his lawyers and participate in a trial. 4. Dr Chew considered that Mr Poynton was then not fit to be tried; that his primary psychiatric issue remained schizophrenia and that he displayed ongoing residual symptoms in the form of voices and low grade paranoia and also had a significant substance use disorder, in self-reported remission in a controlled environment.
Dr O'Dea's May 2016 report 1. Dr O'Dea also considered that on balance, Mr Poynton was unfit to be tried. 2. Although his schizophrenic illness had responded at least partially to ongoing treatment and relative abstinence from illicit substance use in custody, Mr Poynton still reported significant symptoms and presented with significant signs of a schizophrenic illness, that had yet come under adequate control.
July 2016 Mental Health Review Tribunal Determination 1. The Tribunal took account of Dr White's July 2016 opinion, that Mr Poynton was fit to be tried. 2. The Tribunal noted Dr White had diagnosed Mr Poynton as "very likely suffering from schizophrenia characterised by auditory hallucinations and persecutory delusions including third person auditory hallucinations". 3. Dr White also noted that Mr Poynton had a long and substantial history of substance use, particularly methamphetamine, which raised the possibility of drug induced psychosis being his true diagnosis. However given the time his symptoms had persisted, Dr White's view was that seemed less likely, although his ongoing use of psychoactive substances could not be excluded.
Dr Chew's October 2016 report 1. Dr Chew noted that Mr Poynton's primary psychiatric issue remained schizophrenia, and that he displayed ongoing symptoms in the form of voices and low grade paranoia. His substance use disorder was in remission in a controlled environment. 2. Dr Chew considered that Mr Poynton was then fit to be tried.
Dr Nielssen's December 2016 report 1. Dr Nielssen considered that Mr Poynton suffered from schizophrenia and substance use disorder in remission, noting that he had been treated with antipsychotic medication generally reserved for chronic forms of schizophrenia. He remained impoverished in his thinking and had a pattern of intellectual impairment that was consistent with a chronic form of schizophrenia. 2. Dr Nielssen also noted a family history of mental illness; Mr Poynton's reported use of regular drugs, large quantities of methamphetamines as well as cannabis, drugs known to trigger psychotic illness. Because his symptoms had persisted long after he took any kinds of illegal drugs, this suggested that they were due to underlying mental illness, rather than a drug related condition. 3. Dr Nielssen concluded that a defence of mental illness was open to Mr Poynton on the basis of a chronic form of schizophrenia, which produces an abnormality of mind recognised by law to be a disease of the mind. It had resulted in a defect of reason, in the form of the delusional belief that Mr Edwards planned to kill him and also that he should obey voices wanting him and urging him to commit the offences. 4. While Mr Poynton was aware of his actions in firing the gun, on the balance of probabilities he was deprived of the ability to recognise that his actions in committing the offence were morally wrong, as his perception of the events was from the standpoint of his underlying delusional beliefs, that he was in danger and had to obey hallucinated voices. 5. Dr Nielssen also considered that Mr Poynton had available a partial defence of substantial impairment by abnormality of mind under s 23A of the Crimes Act 1900 (NSW), because he had an abnormality of mind at the time of the murders, arising from his underlying chronic schizophrenia illness. That abnormality had affected his perception of the events and his ability to judge right from wrong. As he reported, Mr Poynton believed that he was in danger from the deceased and had to obey the hallucinated voices. 6. Dr Nielssen considered that Mr Poynton would require lifelong treatment with an adequate dose of antipsychotic medication, closely supervised by a forensic mental health service.
Professor Greenberg's May 2017 report 1. Professor Greenberg had earlier examined Mr Poynton in 2012, when he was in custody for juvenile offending. 2. In 2017 he considered that Mr Poynton could be suffering Polysubstance disorder, psychotic illness, Schizophrenia Disorder or Chronic Drug induced psychosis, with a history of ADHD, and personality disorder or traits. 3. He was not fully convinced that Mr Poynton was suffering schizophrenia at the time of the murders, or that auditory hallucinations played any direct commanding role, ordering him to kill his victims, where he had to comply with or obey the orders. Mr Poynton was however, either intoxicated, or had a drug induced perceptual disturbance, auditory hallucinations and paranoid thoughts or both, at the time of the offences. 4. Professor Greenberg was of the view that Mr Poynton did not qualify for a defence of mental illness, because he likely had a degree of reasoning and composure about what he was doing and its wrongfulness at the time. 5. While Mr Poynton's drug induced psychotic symptoms would likely qualify him for a disease of the mind, on balance he did know the nature of his acts and that they were legally and morally wrong. 6. At the time Mr Poynton did have drug induced perceptual disturbances, namely non commanding voices, but the significant feature would have been his heightened or exaggerated paranoid thoughts, from his voluntary use of crystal methamphetamine. This likely would have substantially diminished his capacity for self-control, at that time.
Dr Chew's September 2017 report 1. Dr Chew maintained that Mr Poynton's primary diagnosis was most likely schizophrenia, but that he had improved significantly with treatment and displayed very low grade symptoms in the form of "voices" and low grade paranoia, which likely represented residual symptomology. His persisting psychotic symptoms post stimulant use indicated a brain vulnerability on the spectrum to schizophrenia. He also had significant substance use disorder currently in remission. 2. Dr Chew remained of the opinion that a mental illness defence may be available to Mr Poynton, despite the lack of clarity as to the psychotic symptoms he had at the time of his offending. It was likely that he was then experiencing some kind of psychosis that was persecutory in nature, heightening his anxiety and flight or fight response. He thought that this had affected Mr Poynton's ability to judge right from wrong at the time. 3. In the circumstances he also had the partial defence of substantial impairment available.
Dr O'Dea's April 2018 report 1. Dr O'Dea considered that Mr Poynton suffered a schizophrenic illness, which had continued to respond to ongoing treatment, with an additional polysubstance use disorder, caused by his substance abuse. 2. Despite Mr Poynton's inconsistent and contradictory accounts of the alleged offences and of his mental state at the time, on balance it was reasonable to assume that his schizophrenic illness made a defence of mental illness available to him, as well as the partial defence of substantial impairment.
