Introduction

The case of GC vs. Her Majesty's Advocate ([2022] HCJAC 20) represents a critical examination of the standards required for admitting fresh evidence in appeals against conviction within the Scottish legal framework. The appellant, GC, who faced conviction for the rape of two individuals, SM and LC, sought to overturn his conviction by introducing new evidence presented through the affidavit of MB. MB alleged that SM and LC had conspired to fabricate allegations against GC, thus challenging the credibility of the original prosecution's case.

This commentary delves into the nuances of the Judgment delivered by Lady Dorrien at the Scottish High Court of Justiciary, dissecting the legal principles applied, the precedents cited, and the broader implications for future jurisprudence in the realm of criminal appeals based on fresh evidence.

Summary of the Judgment

GC was convicted on March 16, 2021, for the rape of SM and LC, with majority findings of "not proven" on additional charges. Post-conviction, MB provided an affidavit asserting that SM and LC had intended to fabricate their accusations to secure financial compensation and revenge against GC. Invoking Section 106(3)(a) of the Criminal Procedure (Scotland) Act 1995, GC appealed his conviction, arguing that MB's testimony constituted fresh evidence indicative of a miscarriage of justice.

The High Court conducted an evidential hearing to assess the admissibility and materiality of MB's evidence. Despite recognizing a reasonable explanation for why this evidence was unavailable during the original trial, the court ultimately dismissed the appeal. The primary reasoning was the lack of credibility and reliability in MB's affidavit, compounded by significant inconsistencies and MB's criminal history, which undermined the trustworthiness of her testimony.

Analysis

Precedents Cited

The court referenced pivotal cases to frame its analysis of fresh evidence appeals:

• Al Megrahi v HM Advocate 2002 JC 99: Established the criteria for quashing a conviction based on new evidence, emphasizing the necessity for such evidence to be of significant weight that a reasonable jury would acquit if it had been considered.
• Fraser (NG) v HM Advocate 2008 SCCR 407: Provided further elucidation on the standards for fresh evidence, stressing the importance of the cogency and materiality of the new evidence in the context of the entire trial.
• Church v HM Advocate (No 2) 1996 SLT 383: Distinguished the roles of trial and appellate courts in assessing witness credibility, highlighting that appellate courts should evaluate whether a reasonable jury could find the evidence credible, rather than reassessing credibility themselves.
• Kidd v HM Advocate 2000 JC 509: Reinforced the importance of the overall impression of additional evidence and its significance in possibly altering the trial's outcome.

Legal Reasoning

The court meticulously applied the statutory framework and precedents to determine whether MB's affidavit constituted admissible and materially significant evidence that could overturn GC's conviction. Key legal considerations included:

• Admissibility under Section 106(3)(a): The court evaluated whether MB's evidence introduced previously unheard information that could influence the jury's verdict.
• Compliance with Section 275: Since MB's testimony touched upon the characters of the complainers, the court assessed whether it met the stringent requirements to admit such evidence without infringing on protections under Section 274.
• Credibility and Reliability: Central to the appeal was the court's evaluation of MB's trustworthiness, especially in light of inconsistencies between her affidavit and subsequent police statements, as well as her conviction for attempting to pervert the course of justice.
• Materiality: The court scrutinized whether MB's evidence would have had a substantive impact on the jury's decision-making process during the original trial.

Ultimately, the court concluded that despite meeting procedural prerequisites, MB's evidence lacked the necessary credibility and reliability to influence the jury's verdict, thus upholding the original conviction.

Impact

This Judgment reinforces the high threshold for admitting fresh evidence in criminal appeals, particularly emphasizing the importance of witness credibility. It serves as a deterrent against attempts to introduce unvetted or unreliable testimonies post-conviction and underscores the judiciary's commitment to maintaining the integrity of the trial process. Future cases will likely reference this decision when assessing the admissibility and weight of new evidence, particularly in scenarios where the credibility of new witnesses is in question.

Complex Concepts Simplified

Fresh Evidence

Fresh evidence refers to new information or testimony that was not presented during the original trial. For such evidence to be considered in an appeal, it must be significant enough to potentially alter the outcome of the case.

Miscarriage of Justice

A miscarriage of justice occurs when the application of legal procedures results in an unfair outcome, such as convicting an innocent person or acquitting a guilty one. Appeals on this ground seek to rectify such injustices.

Sections 274 and 275 of the Criminal Procedure (Scotland) Act 1995

Section 274 restricts the introduction of evidence that could undermine the character or credibility of the complainer (victim), especially in relation to their reliability as a witness. Section 275 outlines the conditions under which such restricted evidence can be admitted, ensuring that it is directly relevant, significant, and outweighs any potential prejudice.

Conclusion

The Judgment in GC vs. Her Majesty's Advocate underscores the Scottish judiciary's rigorous standards for admitting fresh evidence in criminal appeals. By meticulously evaluating the credibility and reliability of new testimonies, the court ensures that convictions are both just and based on robust evidence. This decision not only reaffirms the principles set forth in foundational cases but also serves as a guiding beacon for future appellants seeking to challenge convictions through the introduction of new evidence.

Ultimately, the refusal of GC's appeal highlights the paramount importance of witness credibility and the challenges inherent in overturning convictions based on post-trial affidavits that lack consistency and reliability. Legal practitioners must thereby exercise caution and thoroughness when presenting fresh evidence, ensuring it meets the stringent criteria established by precedent to withstand appellate scrutiny.
