Was the Appellant Schizophrenic in February 2002?
31 The appellant was born in Canberra on 8 July 1978. He was the youngest of four children. His mother was a teacher. He had a happy childhood. There was no history of mental illness in his family. He left school at the end of Year 10. He thereafter worked in various jobs, performing labouring work. By the time he left school, he was using cannabis regularly.
32 On 27 March 1997, the appellant, then aged 18 years, pleaded guilty to robbery in company. He saw a psychologist, although he acknowledged that he lied to her in various ways which he thought would advantage him. He was ultimately sentenced to five years imprisonment with a minimum term of two years. He was released on parole on 25 March 1999. The offences which are the subject of this appeal were committed whilst he was on parole, although his parole had almost expired.
33 After his release from gaol, Mr Rigby said that he ceased using cannabis. His parents, however, noticed changes in him. Dr Rosalie Wilcox, a psychiatrist attached to Long Bay Gaol, recorded the following comments from the appellant's parents in her report of 15 July 2004: (p3)
"I have spoken to Mr Rigby's parents who report noticing a difference when he came out of gaol in 1999 and that he was very anxious and did not like social situations and family gatherings. They report he would often sit by himself and laugh as though sharing a joke but only with himself."
34 An affidavit was filed by the appellant's mother. She stated that before the offences the appellant behaved oddly. She added:
"2. ... He often had mood changes. He would come home from work and say 'they've put security in at work; they're watching me'."
35 Mrs Rigby added:
"3. There were times before the offence when Michael had been away from home for a few days and he'd come back unclean and scruffy. He had not been like that normally. He'd sleep and you'd have trouble getting him moving. He'd sleep all day if you'd left him. This was in contrast to the other times when he was working and keeping long hours but he was able to travel long distances and work and keep on top of it."
36 In about February 2001, Mr Rigby began working for a printing company in Sydney. A year later, at the time of the offences, he was still employed by that company. As I will shortly explain, each doctor who has expressed an opinion on Mr Rigby's mental condition, has identified his employment with the printing company as an important aspect of his history in terms of understanding the schizophrenia which was later diagnosed.
37 However, reconstructing what happened to Mr Rigby whilst so employed in the weeks and months before the offences is not easy. His accounts to doctors have not always been consistent. But more than that, what he has said about what happened must be approached with caution. As already mentioned, he has acknowledged that he deliberately lied to a psychologist in 1997 when interviewed in the context of the armed robbery offence. He lied because he saw advantage in doing so. It is also now plain that his account concerning the circumstances leading to intercourse with the complainant was false, and again to his advantage.
38 That said, there is, nonetheless, a certain consistency in the history he has provided to a number of doctors over a number of years. His account, in some cases, is corroborated in one way or another.
39 First, he repeatedly described the odd life he was leading in the period shortly before the offences were committed. Mr Rigby provided Dr Westmore with the following history: (report 16.9.05: p5)
"He then told me that in August 2001 he was homeless. He left the previous workplace and in March 2001 he was travelling, possibly repeatedly, between Sydney and Newcastle by train. He said he felt comfortable being around people on trains and he felt people could understand his thoughts. He said he now understands this is part of his mental illness, schizophrenia. He said he was also crying a lot of the time."
40 Dr Lucas, retained by the Director of Public Prosecutions, received a similar history, although referable to a shorter time period: (report 11.5.06: p5)
"At the time of the offences he was living in a backpackers hostel in Sydney. He had been there one week after living on trains for a month. His parents had asked him to leave home because he was gambling his wages and talking about problems at work. He was not paying his bills. When he left home he lived in a Christian hostel where he did not have to pay, then in another hostel, apparently briefly."
41 The appellant's mother, in her affidavit, said that her son left home a short time before the offences. She understood that he was boarding in Sydney. It is apparent from the circumstances of the offences that, in the early hours of 28 February 2002, Mr Rigby was on a train travelling to Newcastle when he met the complainant.
42 The second aspect concerns the difficulties experienced by Mr Rigby at work. When first examined by Dr Westmore on 22 January 2003, he provided the following history: (report 27.1.03: p4)
"He said he had some problems at the time, particularly at work. There was some conflict at work which had been ongoing for the previous ten months. This was to do with rates of pay and relationship problems he and other workers were having with a supervisor."
43 When, in June 2004, Mr Rigby was admitted to D Ward (the psychiatric ward at Long Bay Gaol) he told the psychiatrist, Dr Rosalie Wilcox, the following: (report 15.7.04: p3)
"... It would appear that he had some altercations with his boss in a printing company and that his boss treated him rudely on several occasions. He appears to be preoccupied with this workplace incident to the extent that he is unable to discuss anything else other than occasional mentions of his family."
44 By the time Dr Westmore examined Mr Rigby for a second time, on 12 September 2005, he had already been diagnosed as suffering from schizophrenia and had been receiving treatment for more than a year. Dr Westmore's second report included the following history: (report 16.9.05: p3)
"Mr Rigby said he walked out of work after Matthew verbally abused him. He said he was in a 'state of shock'. He told me he returned to where he had been living, that is in the hostel, and he said he took 'a little child our without asking her parents'. He said the 'confusion' from the workplace situation affected what he did after he left the workplace on that occasion. He said he felt he was going to do something irrational. He then took the child back to the hostel. He said he had looked after the child previously with the permission of the child's parents."
45 Dr Westmore's report continued: (p3)
"I asked Mr Rigby what occurred in relation to the offending behaviour. He said it was all based around his work and his 'confusion'. He said on 26 February Matthew 'went off his head at me'. On 27 February he reports he was sexually assaulted in the hostel. He went to work but he wanted an explanation, an apology. He said he was looking at the clock in a certain way and he thought he was giving people signals that somebody should apologize to him."
46 Dr Lucas who, it will be remembered, saw Mr Rigby in May 2006, recorded the following in his report: (report 11.5.06: p5)
"... He was talkative and almost immediately mentioned his employment at Principal Press, going on to talk about his circumstances in the period before the offences."
47 The report of Dr Lucas continued: (p6)
"He felt as though he was being tortured by this and belittled by Mr Dickson, believing that Mr Dickson was doing this because he had not been paid correctly. He thought these matters were linked."
48 Dr Lucas added: (p7)
"... However, on 26 February 2002, Mr Dickson went off the deep end at him, worse than he had done previously, calling him names and blaming him for some error. ... The effect of the abuse that day was 'the end of my being who I was'. He thought of Mr Dickson and had recurrent thoughts of 'the hard or the easy way' and 'superintendent'. He had 'pictures' of what Mr Dickson was doing to him."
49 Dr Lucas, commenting upon this history, said this: (p14)
"I note from the file that Mr Rigby has had symptoms of psychosis since beginning treatment but generally has improved. One thing has not changed, obsessive preoccupation with his previous workplace."
50 This, then, was the context within which Mr Rigby sexually assaulted the complainant. I should defer, for the moment, the issue of whether Mr Rigby was, as a matter of probability, suffering from schizophrenia on 28 February 2002 when he committed these crimes and, if he was, whether that mental condition can be linked to his behaviour that night. Before addressing those questions, it is instructive to examine what happened thereafter.
51 Having been arrested, the appellant was given bail. He returned to live with his parents. His obsession with his perceived mistreatment at work was also evident to his parents. His mother, in her affidavit, described her son's behaviour in the period after his arrest, and whilst awaiting trial:
"6. During the time he was on bail Michael would come home and quite often lay on the lounge room floor and go on about Matthew the supervisor at work. Michael reckoned that Matthew had been sent by the transit police to get information on him. It was common for him to say this to us. You couldn't reason with him. He'd say, 'you don't understand' and go to his room. It was hard to make sense of what he was saying."
52 His behaviour remained odd. His mother said this:
"7. Frequently Michael would come home quite agitated and annoyed with things but he didn't say a lot about it. We couldn't reason with him. At first he kept saying, 'when they see the video they'll know the truth'. Then he'd say, 'you can't lie the truth will come out'. Michael can't understand that people can and do lie and that his word alone, in the absence of other evidence, is not enough. He believes that he should be believed.
8. Michael would fixate on things and there is no way he can be diverted. Nothing else exists until he sorts out the problem with Matthew the supervisor at work. Whilst he was living with us he was commuting to Newcastle and his job at the printing shop. I'm not sure what his circumstances were at work during this time."
53 On 25 September 2002, the bail conditions were varied to enable Mr Rigby to live with his sister. Her husband had a fencing business in which he employed the appellant.
54 The trial began on 27 November 2002 in Newcastle. Dr Wilcox, in her report of 15 July 2004, recorded the following comment made by Mr Rigby's parents concerning difficulties which arose during the course of the trial: (p3)
"They report that at the time of his trial his barrister was concerned about his ability to receive instructions from Mr Rigby and organised for a psychiatric report to be done, however Mr Rigby refused to participate in this report and so he was tried and sentenced."
55 The appellant gave evidence on 3 December 2002. The Crown, in its submissions, made the following comment upon that evidence, which I believe is accurate: (para 39)
"Although rejected by the jury, his evidence was clear, consistent and lucid. Furthermore, the applicant gave no account in his evidence of being preoccupied with issues concerning his employment or (naturally, in the light of his plea) of using the phrase 'the hard way or the easy way'."
56 The jury returned its verdict on 4 December 2002 after a short deliberation. The matter was stood over to deal with submissions on sentence. Mr Rigby was remanded in custody. Whilst in custody, he was assessed on 6 December 2002 by a team which included two psychologists. The notes of that assessment included the following observations:
Affect - restricted; controlled;
inappropriate laughter.
Speech - normal rate & flow
Thoughts - logical & sequential.
Sleep - broken; light sleep.
Appetite - (ticked)
Orientated - T (ticked) P (ticked) P (ticked) future (crossed)
57 The solicitors acting for Mr Rigby arranged for him to see Dr Westmore. Reference has already been made to that examination which took place on 22 January 2003. Dr Westmore noted "obvious levels of anxiety and mild agitation" (p2). Mr Rigby maintained his innocence, although he became "noticeably agitated when talking about the offending behaviour" (p5). He was able to maintain good eye contact and speak spontaneously and expansively. Dr Westmore added: (report 27.1.03: p4)
"... He reports that his appetite, weight, sleep patterns and energy levels are all normal. He denies any thoughts of self harm. No psychotic features such as delusions or hallucinations were displayed or described and he presented as being an alert and attentive historian."
58 Dr Westmore described the way in which he presented in these words: (p4)
"... His affect was intense, anxious and very focused although he became obviously more relaxed as the interview progressed. His mood state was generally restricted and possibly subdued but I did not think he was suffering from a major depressive illness and he could also demonstrate some smiling behaviour. There were occasions when I wondered whether he was smiling in a slightly incongruous fashion. This occurred about half way through the interview but at this time I am unable to place too much significance or emphasis on this aspect of his presentation having seen him on only one occasion."
59 Dr Westmore's conclusion was in these terms: (p5)
"I am unable to identify any psychiatric or psychological condition present in Mr Rigby at the time of the offending behaviour. I would however, be recommending that he see a psychologist while in custody, he is obviously highly anxious and having some trouble adjusting to being in prison at this time."
60 Dr Westmore was therefore not called when submissions on sentence were made, and his report was not tendered. The appellant was sentenced on 12 March 2003.
61 On 24 December 2003, after a year of incarceration, Mr Rigby was examined by Dr Diamond, psychiatrist. The report of Dr Wilcox incorporated Dr Diamond's findings, which were as follows: (report 15.7.04: pp1-2)
"Dr Diamond noticed evidence of acute psychosis with delusional beliefs, somatic delusions and thought disorder. He reported that he was paranoid, suspicious and insightless and refused to co-operate with an interview. He talked of having syphilis and the evidence of this was that he could feel movement in the skin of his forehead and in his eyebrows.
He refused to divulge any information saying that he needed to see a lawyer and not a doctor. With subsequent reviews by Dr Wilcox and Dr White, he remained evasive, guarded and suspicious and thought disordered. He talked of having been treated for his Chlamydia, which had improved his eyesight, his muscle strength and several other things. He talked of having been suffering from undiagnosed Chlamydia for many years and that he felt significantly better once treated for this.
He continually refused to discuss other issues saying that it was a workplace issue that needed to be discussed with the solicitor and he did not want to talk to medical staff. He refused any offer of medication and maintained that there was nothing wrong with his mental state."
62 Dr Wilcox saw Mr Rigby on 9 February 2004. She found him "very thought disordered, evasive and guarded". She certified him mentally ill. She said this:
"He was preoccupied with various somatic issues and was focussed on seeing a solicitor to discuss work issues as he believes all his problems relate to something that occurred at work. He has refused to take medication. He does not believe he has a mental illness. He has been overly concerned about diseases."
63 On 22 July 2004, the Mental Health Review Tribunal conducted a hearing under s86 of the Mental Health Act 1990. Dr Wilcox prepared a report for that hearing (15 July 2004). At the time she did so, Mr Rigby was in Ward D, the psychiatric ward at Long Bay Hospital, where he remained for a number of months. Dr Wilcox described his mental state upon admission in these terms: (report 15.7.04: p3)
"... There was reduced eye contact and limited rapport developed. His speech was of normal speed, volume and rhythm. He reported his mood as normal. His affect was somewhat incongruent. He was preoccupied, anxious, guarded and suspicious. He was easily tearful. He denied any ideas of harming himself or others. He was noticeably thought disordered with derailing and loose associations. The content of his thought appeared to include somatic preoccupation, probably delusional in intensity regarding Chlamydia and its effect and the affect of antibiotics on his skin; in the muscles on his forehead. He also seemed quite persecuted but would not elaborate. He denied any hallucinations and there was no clear evidence at interview that he was hallucinating. He had no insight into his illness and his judgement appears affected."
64 Mr Rigby was, at this point, still refusing medication. In these circumstances Dr Wilcox expressed the following view: (p4)
"We are of the opinion that Mr Rigby suffers from schizophrenia, which is chronic and untreated. His illness is characterised by preoccupation with minor events and somatic concerns and thought disorder. It would appear that his illness has impacted on his ability to socialise in the gaol community but also on his ability to participate in his trial. There is also a likelihood from information from his father that his illness was associated with his index offence.
We are of the opinion that Mr Rigby requires ongoing treatment in the Long Bay Hospital as he has continued to refuse to voluntarily accept medication.
Mr Rigby's illness has already caused him significant harm and possibly caused harm to the victim of his offence. We are of the opinion that continued treatment is necessary to prevent further harm."
65 When Dr Westmore saw Mr Rigby again in September 2005, he had available the prison medical file and other material. In the light of that material, he formed a different view from that expressed in his report of 27 January 2003. In his opinion, the appellant was suffering from schizophrenia at the time of the offence. He said this: (report 16.9.05: p6)
"Mr Rigby's longitudinal history supports the proposition that he suffers from a schizophrenic illness, probably of a paranoid type. It is likely he first developed signs of mental illness some time in the late 1990s, that opinion is supported by history given to others by his parents. They noticed changes in him in 1999. Mr Rigby also provides a history supportive of the proposition that he was mentally ill prior to the offending behaviour and I refer to relevant aspects of that history which I have noted in this report. He talked about, for example, being on trains and believing that people on trains could understand his thoughts.
In relation to your specific questions I would advise you that it is my opinion that Mr Rigby was mentally ill at the time the offending behaviour occurred and that he remains mentally ill although there has been some positive response to treatment."
66 Dr Westmore then addressed the issue whether the schizophrenia had affected Mr Rigby's behaviour in sexually assaulting the complainant on 28 February 2002. His view was as follows: (p6)
"Trying to determine what relationship if any his mental illness has in relation to the offending behaviour is more difficult. There is in his mind a direct and positive relationship between thought he was having arising from workplace difficulties and the offending behaviour itself. There may be a link between some thoughts he was having arising from his workplace and some thoughts he was having at the time the offending behaviour occurred and certainly if he was acutely psychotic at the time of the offending behaviour, then his ability to think in a clear and rational fashion is likely to have been affected. This proposition is supported by other aspects of disordered thinking he appears to have had at and around the time the offending behaviour occurred preceding that time. The statements he says he made to the victim about being a supervisor and that he could do it 'the hard way or the easy way' may also have a non psychotic meaning or explanation.
The reported sexual abuse he experienced in the hostel and its relationship to the offending behaviour is also unclear. There is probably no direct link but that event would have been disturbing and distressing for him and would have unsettled him further."
67 His conclusion was in these terms: (p7)
"I have no evidence that he was acting on delusional beliefs or auditory commands in relation to the victim and at this stage nothing to clearly suggest that he might have a mental illness defence to the sexual assault charges.
Nevertheless, the fact that he was mentally ill and that his illness would have impacted on his thought processes may have relevance to the sentence he received and possib[ly] to the conviction although that is obviously a matter for his legal representatives."
68 Dr Lucas, retained by the Crown, appeared to share Dr Westmore's view. When addressing the issue of whether Mr Rigby was suffering from schizophrenia prior to the offences, he said this: (report 11.5.06: pp 14 -15)
"Mr Rigby's diagnosis of chronic paranoid schizophrenia is well established. The question of concern in relation to his appeal is when the illness began. Paranoid schizophrenia often has an insidious onset with prodromal changes in a person's functioning and mental state being recognised only in retrospect.
It is my opinion, on the balance of probabilities, Mr Rigby's mental illness began prior to the offences of 28 February 2002."
69 Was that disease linked to Mr Rigby's offending behaviour? Dr Lucas, perhaps more tentatively than Dr Westmore, appeared to support such a link. He said this: (pp 15-16)
"What he said to me indicated difficulty comprehending aspects of his offences. Some of his ideas made it difficult for him to accept responsibility in a normal way. It is likely this would have prevented him expressing remorse at the time of sentencing.
I think the history we now have of his illness could well have been relevant at the time he was sentenced. Dr Westmore and I agree on this issue. We also agree that it is difficult to decide whether he might have had a defence of mental illness to the charges of sexual assault. He was not psychiatrically assessed at pre-trial. Although one cannot exclude that an assessment may have led to such a defence being raised, on the basis of my interview with Mr Rigby I could not form an opinion that he had such a defence. However, if he was psychotic, as appears probable, with the degree of confusion and turmoil he described, it is possible this may have impaired his judgement and control, but to what extent is difficult to decide in retrospect."
70 There can be little doubt, on this material, that Mr Rigby was suffering from schizophrenia at the time he committed the offences. The more difficult issue is the extent to which that illness provides, as a matter of probability, an explanation (or part of the explanation), for his behaviour diminishing his culpability. His actions were predatory, persistent and displayed a certain cunning. His comment afterwards ("I just raped you, hey.") demonstrated, I believe, that he knew what he was doing and that it was wrong. It would appear that his schizophrenia was evolving and became worse with time. At the time he committed the offences he was plainly able to function at a certain level. He later deteriorated such that his illness became more obvious.
71 Nonetheless, I accept as a probability that at the time of the offence his ability to think rationally about what he was doing and to control his impulses was impaired by the mental illness from which he was then suffering. The incident at work two days before appears to have profoundly affected him. The proximity of that incident and the odd behaviour which followed, including travelling all night on trains between Sydney and Newcastle, suggests that his mind was in some turmoil when these offences were committed.
72 The material which the appellant seeks to rely upon as fresh evidence meets the test for the admission of fresh evidence. The condition was present at the time he was sentenced. It was not recognised and therefore not taken into account. It can now be seen, nonetheless, that it was relevant to the sentencing task. I see no absence of diligence on the part of Mr Rigby's solicitors.
73 I then turn to the issue of resentence and whether some other sentence was warranted in law (s6(3) Criminal Appeal Act 1912).
