Affirmation of Reasonable Explanation Requirement for New Evidence in Rape Conviction Appeals in Scotland

Introduction

The case of Dylan Williamson and Kiara-Lee Gallagher ([2021] ScotHC HCJAC_50) presents a pivotal examination of appellate evidentiary standards within the Scottish High Court of Justiciary. This appeal concerned the convictions for rape against both appellants, delivered in the context of two separate charges. The appellants challenged the sufficiency and interpretation of forensic medical evidence regarding genital injuries and the assessment of consent during the original trial. Central to the appeal was the contention that newly introduced expert testimonies undermined the initial forensic conclusions, potentially altering the jury's perception of consent. The parties involved included the appellants, legal representatives, and Her Majesty's Advocate as the respondent.

Summary of the Judgment

On December 8, 2021, the Scottish High Court of Justiciary rendered its decision on the appeals led by Dylan Williamson and Kiara-Lee Gallagher against their respective rape convictions and sentences. The appellants sought to introduce new forensic medical evidence to contest the credibility of Dr. Kranti Hiremath's testimony, which had been pivotal in establishing the likelihood of non-consensual intercourse based on genital injuries and pain reported by the complainants.

The court examined whether the appellants provided a reasonable explanation for the original trial not considering the additional forensic testimonies. It also evaluated whether the new evidence could have had a material impact on the trial's outcome. Ultimately, the court dismissed the appeal, affirming that the appellants did not meet the necessary criteria to introduce the new evidence. Furthermore, the court modified Mr. Williamson's sentence from an extended determinate sentence to a standard determinate one, citing insufficient grounds for the original extended sentence.

Analysis

Precedents Cited

The judgment extensively referenced several key precedents which shaped the court’s approach to appellate review, particularly regarding the introduction of new evidence:

• Meighan v HM Advocate 2021 SCCR 247: This case was instrumental in establishing the framework for evaluating the admissibility of new forensic evidence on appeal, emphasizing the necessity of a reasonable explanation for its omission during the original trial.
• Grant v HM Advocate 2006 JC 205: Provided the test for defective representation appeals, underscoring the importance of comprehensive defense preparation and the consequences of failing to contest expert testimonies effectively.
• Singh v HM Advocate 2013 SCCR 337: Addressed the late lodging of grounds of appeal, reinforcing procedural requirements for including all appeal grounds within the initial Note of Appeal.
• Campbell v HM Advocate 1998 JC 130 & 1998 SCCR 214: These cases highlighted the necessity of a broad and flexible approach in determining the existence of a reasonable explanation for the non-admittance of new evidence.
• Megrahi v HM Advocate 2002 JC 99: Emphasized that appellate courts should refrain from making factual determinations, leaving such assessments to juries unless clear miscarriages of justice are evident.
• Johnstone v HM Advocate 2013 HCJAC 29 & 2013 SCCR 487: Clarified that new evidence must not only be credible and reliable but also significantly different or unavailable during the trial to merit consideration on appeal.
• Fraser v HM Advocate 2008 SCCR 407: Reinforced that without a reasonable explanation for the absence of new evidence at trial, its introduction on appeal is impermissible, regardless of its potential impact.

Legal Reasoning

The court adhered strictly to the statutory framework outlined in the Criminal Procedure (Scotland) Act 1995, particularly sections 106(3)(a) and 106(3A), which govern the admissibility of new evidence in appeals. The key legal reasoning encompassed:

• Reasonable Explanation Test: The appellants needed to demonstrate a compelling reason why the additional forensic testimonies were not presented during the original trial. The court assessed whether the omission was justifiable under the principles of legal finality and procedural fairness.
• Material Significance of New Evidence: Beyond the reasonable explanation, the appellants were required to show that the new evidence would have had a substantial impact on the trial's outcome, potentially leading to an acquittal.
• Expert Testimony Standards: The court evaluated the reliability and relevance of the new expert testimonies compared to those presented at trial, determining whether they offered a fundamentally different perspective or merely reiterated existing conclusions with minor variations.
• Finality of Verdicts: Upholding the importance of final judgments in criminal proceedings, the court emphasized that reopening cases without stringent justification could undermine the legal system's integrity.

The court found that the appellants failed to provide a sufficient reasonable explanation for not introducing the new evidence during their trial. Additionally, the new forensic opinions did not present a significant deviation from previous expert conclusions to the extent that they would alter the jury's determination of consent.

Impact

This judgment reinforces the high threshold required for introducing new evidence on appeal, particularly in serious criminal cases like rape convictions. Key impacts include:

• Strengthening Appellate Standards: The decision underscores the necessity for appellants to present compelling reasons for the exclusion of evidence in initial trials and to demonstrate significant potential impact to warrant appellate consideration.
• Clarifying Forensic Evidence Roles: It affirms the court's stance on the interpretation of forensic medical evidence concerning consent, maintaining that such evidence must be critically evaluated within the broader context of all trial evidence.
• Procedural Finality: By upholding the rejection of the appeal, the judgment emphasizes the importance of procedural finality, discouraging attempts to reopen convictions without substantial new grounds.
• Guidance for Defense Strategy: Legal practitioners are reminded of the critical importance of effectively challenging expert testimonies during trials to prevent similar appellate rejections.

Complex Concepts Simplified

To elucidate the legal intricacies of this judgment, the following key concepts are simplified:

• Reasonable Explanation: A legal standard requiring appellants to convincingly explain why certain evidence was not presented during the original trial. It prevents retroactive inclusion of evidence without justified reasons.
• Forensic Medical Examiner (FME): A medical professional who specializes in examining victims of crimes, particularly sexual offenses, to document and interpret physical injuries.
• Article 6 of the European Convention on Human Rights: Guarantees the right to a fair trial, including the right to present a defense and challenge evidence against the defendant.
• Genital Injury and Consent: The medical examination of genital injuries can provide circumstantial evidence regarding the presence or absence of consent during sexual intercourse, though such evidence alone is not conclusive.
• Extended Sentence: A longer-than-standard prison term imposed on a defendant deemed to pose a significant risk to public safety.
