Introduction

In the landmark case of Head v ([2022] EWCA Crim 1294), the England and Wales Court of Appeal (Criminal Division) addressed critical issues surrounding the prosecution's duty to disclose adverse evidence and the broader implications for the safety of convictions. The appellant, Gareth Head, a 45-year-old police officer, was convicted of assault occasioning actual bodily harm under section 47 of the Offences against the Person Act 1861. This comprehensive commentary delves into the nuances of the case, the court's reasoning, and the precedent it sets for future legal proceedings.

Summary of the Judgment

Gareth Head was initially acquitted of a charge related to the same incident in October 2021 due to a hung jury. However, upon retrial in March 2022, he was convicted by a unanimous jury verdict and sentenced accordingly. Subsequent to his conviction, Head discovered that the prosecution had failed to disclose the complainant's prior convictions for cannabis-related offenses. This omission, deemed a breach of disclosure obligations, formed the basis for his appeal. The Court of Appeal granted leave to appeal, admitted the fresh evidence, and ultimately quashed the conviction, deeming it unsafe.

Legal Reasoning

The Court of Appeal meticulously examined whether the prosecution's failure to disclose the complainant's prior convictions constituted a breach severe enough to render the conviction unsafe. The key points in their reasoning included:

• Disclosure Obligations: The prosecution is mandated to disclose any material that might undermine the prosecution case or assist the defense. The non-disclosure of the complainant's cannabis-related convictions was a clear violation of this duty.
• Impact on Safety of Conviction: The court assessed whether the undisclosed evidence could have influenced the jury's decision. Given that the convictions related to similar misconduct, their disclosure might have bolstered the defense's argument regarding the complainant's reliability, thereby affecting the jury's verdict.
• Application of Precedents: The court applied the McInnes test, focusing on whether there was a real possibility that the jury's verdict would have been different had the evidence been disclosed. The analysis concluded affirmatively, justifying the quashing of the conviction.
• Credibility and Context: The court emphasized the importance of the complainant's credibility in the case, noting that prior convictions could significantly impact the jury's perception of his testimony.
