Factual and Procedural Background
On 28 October 1986, the Appellant was convicted of five counts of murder following a 19-day Crown Court trial before Judge Drake and a jury. He was sentenced to life imprisonment with a minimum term of 25 years. The Appellant sought leave to appeal against conviction, which was initially refused by a single judge but renewed to the full court and dismissed on 20 March 1989. The case returned to the court following a reference by the Criminal Case Review Commission (CCRC) based solely on fresh scientific evidence related to DNA testing of the sound moderator used in the murders.
The murders occurred in the early hours of 7 August 1985 at White House Farm, Essex, where five family members were shot dead. The prosecution alleged the Appellant killed all five, motivated by inheritance, while the defence contended that the Appellant's sister, who had a history of mental illness, committed the murders and then took her own life. The police investigation initially accepted the suicide theory but later shifted focus to the Appellant following new evidence and witness statements. The case attracted significant media attention due to the nature of the killings and the family relationships involved.
Legal Issues Presented
- Whether the convictions are unsafe in light of fresh scientific evidence, particularly DNA testing of the sound moderator.
- Whether failures in disclosure and alleged police misconduct affected the safety of the convictions.
- Whether the evidence at trial, including the handling of the crime scene and witness credibility, was sufficient to uphold the convictions.
Arguments of the Parties
Appellant's Arguments
- Alleged non-disclosure of significant evidence, including police documents, scientific reports, and witness statements, which could have undermined the prosecution case.
- Claims of police misconduct, including suppression of evidence and fabrication, particularly regarding hand swabs and the handling of the crime scene.
- Challenges to the scientific evidence related to blood and DNA in the sound moderator, arguing contamination and alternative explanations.
- Assertions that the Appellant's sister was the true perpetrator based on her mental health history and physical incapacity to have committed the crimes.
- Disputes over the timing and content of telephone calls relevant to the case, including those to the police and a key witness.
- Allegations that key witnesses, notably the Appellant's former girlfriend, had credibility issues and that relevant information about their conduct was withheld.
- Contentions regarding the significance of certain physical evidence, such as a photograph of a carving and the Bible found at the scene, which were allegedly not disclosed or improperly handled.
Prosecution's Arguments
- The prosecution maintained that the evidence, including witness testimony, forensic analysis, and the Appellant's own admissions, supported the convictions.
- They argued that the alleged non-disclosures were either immaterial, not withheld deliberately, or would not have affected the jury's verdict.
- Regarding police conduct, the prosecution denied any wrongdoing and pointed to extensive investigations and reviews confirming the integrity of the inquiry.
- They contended that the scientific evidence, including blood group testing and DNA analysis, supported the conclusion that the Appellant was responsible and that the Appellant's sister could not have committed the murders.
- The prosecution opposed the admission of fresh evidence that was available or could have been obtained at trial and argued it would not have altered the outcome.
- They rejected claims of contamination affecting the DNA evidence and emphasized the strength of the cumulative case against the Appellant.

Court's Reasoning and Analysis
The court conducted a detailed examination of each ground of appeal, focusing on the reliability of the evidence and the conduct of the police and prosecution. Regarding the hand swabs from the deceased sister, the court found no evidence of police misconduct or conspiracy to conceal information, concluding that any failure to disclose did not affect the safety of the conviction.
On the disturbance of the crime scene, the court found no credible evidence that police officers had disturbed furniture or spilled sugar, and concluded that the scene showed evidence of a violent struggle consistent with the prosecution case.
Concerning the windows alleged to have been used for entry and exit, the court noted conflicting police statements but found that the appellant himself admitted to entering the property via windows, negating any defense based on window security.
The timing of key telephone calls was analyzed with reference to witness statements and notes. The court found no undisclosed material that would have altered the jury’s assessment of the evidence.
The credibility of a key prosecution witness was considered in light of admitted past dishonesty and alleged non-disclosure of immunity. The court found no evidence of improper conduct or that the jury was misled in a material way.
Regarding physical evidence such as a photograph showing a carving and the Bible found at the scene, the court was satisfied that these were disclosed or of minimal relevance and would not have affected the jury’s verdict.
The court thoroughly assessed the scientific evidence related to blood and DNA in the sound moderator. It rejected the appellant’s challenges based on fresh expert opinions, noting that the original forensic scientist’s conclusions were supported by evidence and that the possibility of contamination or alternative explanations did not render the convictions unsafe.
Finally, the court considered the general allegation of police misconduct and found no credible evidence supporting claims of conspiracy or wrongdoing that would undermine the prosecution case or trial fairness.
Holding and Implications
DISMISSED
The court dismissed the appeal, concluding that none of the grounds raised undermined the safety of the convictions. The verdicts were considered ones the jury were plainly entitled to reach based on the evidence. No new precedent was set by this decision. The direct effect is that the convictions and sentences remain upheld and the Appellant’s conviction for the murders stands.
