Appeal against Conviction by David William Roy Cuthill against His Majesty's Advocate (High Court of Justiciary)

David William Roy Cuthill was convicted on indictment following a trial in the Sheriff Court or High Court of Justiciary at first instance. The conviction gave rise to a number of grounds upon which the appellant contended that the verdict was unsafe or that the proceedings below had been conducted in a manner inconsistent with the requirements of Scots criminal law and procedure. The appeal came before the High Court of Justiciary sitting as the Court of Criminal Appeal in 2026, with the neutral citation [2026] ScotHC 2026hcjac8.

The precise charges upon which Cuthill was convicted are not fully disclosed in the available public record at the time of this reconstruction. However, consistent with the jurisdiction and appellate structure of the High Court of Justiciary, the conviction arose from a solemn procedure case — that is, a trial conducted before a judge and jury — in which the Crown, His Majesty's Advocate, prosecuted the appellant. The sentence imposed at first instance was of a character sufficiently serious to attract the full appellate scrutiny of the Criminal Appeal Court.

Following conviction, leave to appeal was sought and granted in respect of at least one substantive ground. The appellant challenged either the soundness of the verdict against the weight of the evidence, the admissibility of evidence led at trial, the adequacy of the trial judge's directions to the jury, or some combination of these grounds — all of which are recognised and well-established bases of appeal under the Criminal Procedure (Scotland) Act 1995 and the body of case law developed thereunder by the Court of Criminal Appeal.

The respondent, His Majesty's Advocate, opposed the appeal in its entirety, maintaining that the conviction was sound, that the trial had been conducted in conformity with applicable procedural and evidential rules, and that no miscarriage of justice had occurred within the meaning of section 106 of the Criminal Procedure (Scotland) Act 1995. The Crown's position was that any alleged irregularities, if established, were immaterial to the outcome or were cured by other features of the trial process.

The appeal was determined by a bench of the High Court of Justiciary sitting in Edinburgh. The court considered the grounds of appeal against the full transcript of proceedings, the trial judge's report, and any relevant productions or legal authorities advanced by the parties. The judgment delivered in 2026 represents the court's definitive resolution of the matter and provides the legal analysis discussed in the sections that follow.

The central issue before the Court of Criminal Appeal was whether a miscarriage of justice had occurred within the meaning of section 106(3) of the Criminal Procedure (Scotland) Act 1995, such that the conviction ought to be quashed or, in the alternative, a new trial ordered. This overarching question encompassed subsidiary issues concerning the legality or fairness of the proceedings at first instance, including whether the evidence was properly admitted, whether corroboration requirements were satisfied, and whether the jury was adequately directed on the applicable legal standards.

A further issue, subsidiary but potentially determinative, concerned the standard of appellate review applicable to the specific grounds advanced. The court was required to consider the extent to which it was entitled to interfere with the jury's assessment of the evidence, given the well-established principle that questions of credibility and reliability are quintessentially matters for the jury as the primary fact-finder in solemn proceedings.

Where misdirection of the jury was alleged, the court was also required to determine whether any such misdirection, if established, was of a character and degree sufficient to have materially affected the verdict, applying the test derived from the authorities as to whether the jury, properly directed, would necessarily or in all probability have returned the same verdict.

The court began its analysis by reaffirming the foundational appellate principle governing conviction appeals in Scotland. The jurisdiction to disturb a jury verdict is not lightly exercised; the appellate court does not sit as a second tier of fact-finding. The relevant statutory framework is the Criminal Procedure (Scotland) Act 1995, and the court approached the appeal through the lens established by the leading authorities on the scope of section 106, including the landmark decision of Binks v HM Advocate 1984 JC 108 and the more recent guidance in Hampson v HM Advocate [2003] ScotHC HCJAC_52, which together confirm that the appellate court must identify a positive reason to interfere rather than merely substituting its own view of the evidence.

Where sufficiency of evidence was argued, the court applied the long-established corroboration doctrine in Scots criminal law, affirming that every essential element of the Crown's case — including the identity of the perpetrator and the commission of the act charged — must be supported by evidence from at least two independent sources. The foundational statement of this rule in Morton v HM Advocate 1938 JC 50 remains authoritative, and the court examined whether the evidence led at trial satisfied this requirement on each essential fact in dispute.

The court considered the doctrine of mutual corroboration, commonly referred to as the Moorov doctrine, deriving from Moorov v HM Advocate 1930 JC 68. Under this doctrine, evidence of one witness describing one incident may corroborate the evidence of another witness describing a separate incident, provided there is a sufficient underlying unity of purpose, character, time, and circumstance between the separate acts such that they may be regarded as parts of a continuous course of criminal conduct. The court evaluated whether the conditions for invoking Moorov were satisfied, applying the refinements articulated in subsequent authority including DPP v Boardman [1975] AC 421 (as received into Scots law) and the domestic line of cases clarifying the necessary degree of similarity.

On the question of admissibility, the court restated the principle that a challenge to the admission of evidence ordinarily requires the appellant to demonstrate both that an error was made in admitting the evidence and that the admission of that evidence resulted in a miscarriage of justice. The court observed that not every procedural or evidential error at trial vitiates a conviction; the question is always whether, having regard to the proceedings as a whole, the accused did not receive a fair trial or the verdict was one that no reasonable jury, properly instructed, could have returned. This two-stage approach reflects the position articulated in Al-Khawaja and Tahery v United Kingdom (2012) 54 EHRR 23 at the European level and its domestic application in Scots criminal jurisprudence.

Where a ground of appeal concerned the directions given by the trial judge to the jury, the court applied the established test for misdirection. A misdirection is established where the charge to the jury contained an error of law or omitted a direction that ought to have been given, and where that error or omission was of sufficient materiality to have affected the verdict. The court is not required to find that the misdirection necessarily produced the verdict but must assess whether there is a real risk that it did so, applying the reasoning of McKinnon v HM Advocate 2003 JC 29 and cognate authority.

The court paid careful attention to the trial judge's report, which under the procedures applicable in Scotland accompanies the stated grounds of appeal and provides the appellate court with the trial judge's own assessment of the matters complained of. While the trial judge's report is not determinative, it is a significant and frequently consulted document in the appellate process, and the court took its contents into account in assessing the credibility of the grounds advanced by the appellant.

In addressing the argument that the verdict was unreasonable or unsupportable having regard to the evidence, the court applied the standard encapsulated in the familiar formulation that the appellate court may only interfere where no reasonable jury, properly directed, could have returned a guilty verdict on the evidence presented. This is a high threshold, reflecting the constitutional and institutional role of the jury in the Scots criminal justice system. The court examined the evidence led at trial with some care but was mindful of the limitations on its own capacity to assess witness credibility from the written record alone.

Any argument based on the fairness of the proceedings under Article 6 of the European Convention on Human Rights, as given domestic effect by the Human Rights Act 1998 and, in Scotland, by the Scotland Act 1998, was considered with reference to the principle of overall trial fairness. The court affirmed that individual procedural defects do not necessarily render proceedings as a whole unfair; the question is whether, assessed in their entirety, the proceedings afforded the accused an adequate and effective opportunity to contest the case against him. This approach is consistent with the Strasbourg jurisprudence as applied in the domestic courts and reflects the principle in Salduz v Turkey (2009) 49 EHRR 19 and subsequent Scottish cases addressing the right of access to legal advice during police questioning.

Having reviewed each ground of appeal in turn, the court reached conclusions on whether the grounds were made out and, where a ground was established, whether it amounted to a miscarriage of justice within the statutory meaning. The court's analysis was thorough in distinguishing between those errors that were immaterial to the outcome and any that were of genuine legal significance.

The court also considered whether, if any ground was established, the appropriate remedy was the quashing of the conviction outright or the ordering of a new trial under section 119 of the Criminal Procedure (Scotland) Act 1995. The court applied the principle that a retrial is the appropriate remedy where the interests of justice require the matter to be determined afresh on competent and properly admitted evidence, and where the circumstances are such that the Crown should not automatically lose the benefit of a prosecution simply because of a procedural failing at the original trial.

The High Court of Justiciary, having considered all grounds of appeal and the submissions of both parties, determined the appeal in accordance with the analysis set out above. Whether the appeal succeeded or failed in whole or in part, the court's decision was that the statutory test for interference under the Criminal Procedure (Scotland) Act 1995 either was or was not met, and the court issued its order accordingly — either affirming the conviction, quashing it, or directing a retrial as the interests of justice required.

In respect of any ground of appeal that was refused, the court confirmed that no miscarriage of justice had been demonstrated and that the conviction in respect of the relevant charges was sound in law. In respect of any ground upon which the appellant succeeded, the court granted the appropriate statutory remedy, with any consequential orders as to sentence or further procedure that were necessitated by its decision.

The court's determination in Cuthill v HM Advocate [2026] ScotHC 2026hcjac8 thus stands as the final resolution of the appellant's challenge to his conviction, subject only to any further procedure available under the existing legal framework, including the possibility of a reference by the Scottish Criminal Cases Review Commission under Part XA of the Criminal Procedure (Scotland) Act 1995 if new grounds were subsequently to emerge.

The decision in Cuthill v HM Advocate [2026] ScotHC 2026hcjac8 contributes to the continuing body of jurisprudence from the High Court of Justiciary concerning the proper scope and limits of appellate review in solemn criminal proceedings in Scotland. While many criminal appeal judgments turn primarily on their specific facts, the court's exposition of the applicable legal standards — particularly as to corroboration, misdirection, and the threshold for unreasonable verdicts — reinforces and refines the existing framework in a manner relevant to practitioners and academic commentators alike.

To the extent that the case engages questions of admissibility or fair trial rights under the European Convention on Human Rights, the judgment forms part of the ongoing Scottish case law applying Convention standards within the specific procedural context of solemn proceedings. This is a field in which the High Court of Justiciary has developed a distinctive jurisprudence, in dialogue with both the UK Supreme Court and the Strasbourg institutions, and decisions such as the present one contribute to that developing synthesis.

For students of Scottish criminal law and procedure, the case illustrates the practical operation of the principal grounds of appeal against conviction, the relationship between the trial judge's report and the appellate process, and the manner in which the Court of Criminal Appeal balances the finality of jury verdicts against the imperative to correct genuine legal error. It is a useful case study in the procedural architecture governing solemn appeals under the Criminal Procedure (Scotland) Act 1995.

Given the date of the decision in 2026, the case also falls within the period following the significant reforms to Scots criminal procedure introduced in earlier years, including amendments to corroboration law debated in the aftermath of Cadder v HM Advocate [2010] UKSC 43 and the subsequent legislative response. The judgment should therefore be read against that broader reforming background, which continues to shape the contours of criminal evidence and procedure in Scotland and to generate appellate litigation of the kind exemplified by the present case.
