Factual and Procedural Background
Shortly after 7 pm on 4th June 1992, the body of the Appellant's heavily pregnant wife was found hanging in the garage of their home at 6, Grafton Drive, Upton, Wirral. At trial in 1993, it was agreed there were only two possible explanations for her death: suicide or murder by the Appellant. The Appellant did not give evidence and was unanimously convicted of murder by the jury. The conviction was upheld on appeal in 1995. This appeal arises from a reference by the Criminal Cases Review Commission (CCRC) under section 9 of the Criminal Appeal Act 1995, seeking to revisit the safety of the conviction in light of fresh evidence.
The deceased was preparing for the imminent birth of their child, expected around 18th or 19th June 1992, and was described by witnesses and medical professionals as physically fit and positive about the birth, with no history of depression. Several notes and letters, some containing falsehoods about infidelity and paternity, were found, which the prosecution argued were fabricated by the Appellant to support a staged suicide. The Appellant had a history of discussing suicide courses at work, which was a point of contention in the case.
The body was discovered hanging from a beam in the garage, with an aluminium ladder behind. The physical evidence and positioning raised questions about whether the deceased could have committed suicide unaided, especially considering her pregnancy and the difficulty of tying the noose. The police initially treated the death as suicide, but statements from the deceased’s friends prompted a murder investigation. The Crown's case was that the Appellant murdered his wife and staged the scene to look like suicide.
Legal Issues Presented
- Whether the fresh evidence relating to psychological, psychiatric, and pathological aspects, including expert opinions on the mechanics of death, undermines the safety of the Appellant’s murder conviction.
- Whether the psychological autopsy and expert evidence on the deceased’s state of mind and the physical possibility of suicide are admissible and sufficiently reliable to affect the verdict.
- Whether the jury’s verdict remains safe in light of the new expert evidence and whether the inferences drawn from the non-pathological evidence continue to support the conviction.
Arguments of the Parties
Appellant's Arguments
- Fresh evidence from psychological and psychiatric experts (Professor Canter and Dr Weir) and pathologists (Professor Knight, Professor Crane, and Mr Ide) challenges the prosecution’s narrative and suggests suicide is a plausible explanation.
- The psychological autopsy supports the deceased’s suicidal intent, contrary to earlier expert opinions.
- The pathological evidence, including scratch marks on the neck and the position of the body, does not conclusively support murder and is consistent with suicide.
- The Appellant’s movements on the day of death and statements about a suicide course at work require re-evaluation in light of the fresh evidence.
- The verdict is unsafe because the jury might have reached a different conclusion if the new expert evidence had been available at trial.
Crown's Arguments
- The pathological evidence at trial did not prove the mechanics of murder and remains consistent with both suicide and homicide.
- The fresh expert evidence does not undermine the circumstantial case of murder established by non-pathological evidence.
- The jury’s verdict was based on strong circumstantial evidence, including the Appellant’s lies about his movements and the fabrication of suicide notes.
- The court must exercise its own judgment and determine whether the fresh evidence would have reasonably affected the outcome; it would not.
- The new evidence does not prove how the death occurred but the overall evidence supports the conclusion of murder.

Court's Reasoning and Analysis
The court carefully considered the fresh evidence submitted, including psychological, psychiatric, pathological, and forensic knot analysis. It excluded the psychological and psychiatric evidence of Professor Canter and Dr Weir on grounds of inadmissibility, lack of scientific rigor, speculative methodology, and one-sided information. The court emphasized that expert evidence must provide scientific criteria to enable the jury to independently test conclusions, and psychological autopsy evidence did not meet this standard.
Regarding pathology, the court heard from multiple experts. Professor Knight and Dr West indicated that the pathological evidence was consistent with both suicide and homicide and that scratches on the neck could not conclusively distinguish between the two. Professor Crane agreed that the pathological findings did not exclude either cause of death. Mr Ide’s forensic analysis of the knots and rope suggested the deceased was unlikely to have been standing on the floor when the noose was placed and slightly favored the hypothesis of murder, although not conclusively.
The court found that the fresh expert evidence did not materially assist the Appellant’s case or undermine the safety of the verdict. The key issues turned on inferences from the non-pathological evidence: the deceased’s positive state of mind before death, the fabrication of suicide notes, removal of the garage key, the physical improbability of the deceased having tied the noose unaided, and the Appellant’s inconsistent accounts and lies about his movements.
The court rejected the Appellant’s challenges to the credibility of witnesses who placed him at the scene contrary to his account. It held that the verdict depended on the inferences to be drawn from the proved facts, not on resolving factual disputes, as there was no defence evidence. The court concluded that the new evidence did not raise reasonable doubt about the verdict, which remained safe.
Holding and Implications
DISMISSED
The court dismissed the appeal, holding that the fresh evidence did not undermine the safety of the Appellant’s conviction for murder. The verdict was supported by strong circumstantial evidence and the inferences drawn from the totality of the evidence. The decision confirms that psychological autopsy evidence, lacking scientific reliability and criteria, is inadmissible in such cases. The ruling underscores the necessity for appellate courts to independently assess fresh evidence but affirms that the ultimate question remains whether the new evidence could reasonably have affected the jury’s verdict. No new precedent was set beyond the careful application of existing principles on expert evidence admissibility and appellate review of convictions.
