CaseChat Overview and Summary

In the case of R v Lang, the appellant was convicted of murder, following the death of a woman from stab wounds to her abdomen. The deceased and the appellant were the only individuals present in the deceased's apartment prior to her death. The court was tasked with determining whether the appellant's conviction should be upheld, or if there had been a miscarriage of justice due to the improper admission of statistical evidence regarding suicide rates and methods, which the appellant argued was irrelevant and misleading.

The central legal issue before the court was whether the statistical evidence presented by the prosecution was relevant and reliable, and whether its admission, along with the prosecutor's reliance on it, had caused a miscarriage of justice. The appellant's counsel did not object to the statistical evidence or the prosecutor's use of it at trial, but on appeal, the appellant contended that the evidence was both irrelevant and misleading, and that its use was prejudicial.

The court examined the relevance and admissibility of the statistical evidence, considering the deceased's mental health and history, which were pertinent to the hypothesis of suicide. The court found that the statistical evidence was not only irrelevant but also misleading, as it did not accurately reflect the incidence of suicide by cutting, particularly among those with bipolar disorder. The court concluded that the admission of this evidence, along with the prosecutor's reliance on it, had indeed caused a miscarriage of justice.

The court quashed the appellant's conviction and ordered a retrial, reflecting its determination that the improper admission of the statistical evidence had a significant impact on the outcome of the trial. The decision underscored the importance of ensuring that evidence presented in criminal trials is both relevant and reliable, and that its admission does not prejudice the fairness of the proceedings.

Evidence

Evidence Before The Court

Thus, on the evidence of the forensic pathologists, the reasonable possibility that the death was the result of suicide was not excluded. In those circumstances, evidence of the deceased’s mental health, its history and state at the time of her death, was highly relevant to whether the death was the result of a homicide or a suicide. We now turn to that evidence.Evidence as to the deceased’s mental health Dr M J Spelman, consultant psychiatrist, was called in the prosecution case on the fourth day of the trial. He was the deceased’s treating psychiatrist. She had first consulted him in 2001.[4] Dr Spelman gave evidence that he diagnosed the deceased as having either a type 1 or type 2 bipolar disorder and a borderline personality disorder.[5] In a bipolar disorder, the patient could exhibit changes in mood both towards depression and towards mood elevation. With type 1, during the elevated mood the patient would be manic and might need hospitalisation whereas for type 2, the patient would be hypomanic but not need hospitalisation and would have longer depressed periods.[6][4]AB 252 Tr 4-4 ll35-40.[5]Ibid ll44-47.[6]AB 253 Tr 4-5 ll3-27. Dr Spelman testified that the deceased had expressed suicidal ideation to him on quite a number of occasions during the period that he had treated her.[7] That occurred when she was in a depressed state. The more severely depressed she was, the more preoccupied she was with suicidal thoughts.[8] She would say that if she was going to suicide, she would jump off the building in which she was living.[9][7]AB 254 Tr 4-6 ll44-46.[8]AB 255 Tr 4-7 ll1-3.[9]Ibid ll16-17. Dr Spelman gave evidence that the deceased attended a consultation with him at the Belmont Hospital on 20 October 2015. In his opinion, she was “reasonably settled”. It was not evident to him that she was either depressed or manic. She did not tell him she was feeling suicidal. He did not believe that she was at any risk of taking her life at that time.[10] Next, Dr Spelman was asked about medications taken by the deceased as they related to mood and about her health otherwise.[10]AB 261 Tr 4-13 l39 – AB 262 Tr 4-14 l8. At that point in the evidence in chief, the prosecutor turned to the subject of methods of suicide. He asked Dr Spelman whether people who suffer from bipolar disorder are more likely to commit suicide. The answer was “Yes”. Dr Spelman added that it is generally accepted that patients with bipolar disorder have a five per cent risk over a lifetime of killing themselves which is higher than the prevalence in the general population “of the order of one in 10,000”.[11][11]AB 266 Tr 4-18 ll36-46. When the prosecutor asked about figures for means of suicide, defence counsel objected on the basis that he had not been given any material to indicate that the topic would be raised.[12] Argument ensued in the absence of the witness and the jury. The prosecutor said that he understood that Dr Spelman would give evidence that there was no correlation between bipolar disorder and any particular means of suicide. The learned trial judge indicated that he would allow that evidence. He said that if Dr Spelman was to be asked about the incidence in general of suicide by cutting, then he should reduce any opinion he had to that effect to writing supported by the relevant literature and that it should be provided to the defence.[13][12]AB 267 Tr 4-19 ll1-15.[13]AB 270 Tr 4-22 ll11-18.
