Mannix v R

[2020] NSWDC 34

Assault & violence
APPEAL ASSAULT ON PRISONER BY PRISON OFFICER CCTV EVIDENCE ACTING IN SELF DEFENCE

Citation: Mannix v R [2020] NSWDC 34
Court: District Court of New South Wales
Date: 24 January 2020
Judge: Hatzistergos DCJ

Background

The appellant was the Governor of a correctional centre at Silverwater. On 13 April 2018, a correctional officers' industrial strike had left the facility significantly understaffed, with most of the 515 inmates locked in their cells. The complainant, an inmate serving time for a dishonesty offence, had been selected to assist with meal distribution but was observed by officers moving slowly, looking into cells, and speaking with other inmates despite being directed to stop.

After the complainant failed to comply with repeated directions from a senior officer, the appellant and three colleagues climbed the stairs to the walkway where the complainant was working. A confrontation followed. The appellant's account was that the complainant raised his arm, swore aggressively at her multiple times in an escalating manner, and that she perceived a threat to her safety. The complainant's account differed.

The Local Court at Burwood convicted the appellant of common assault under s 61 of the Crimes Act 1900 (NSW). The appellant, a correctional officer of 35 years with no prior record, appealed that conviction to the District Court.

  • Whether the District Court, on appeal from the Local Court under s 18 of the Crimes (Appeal and Review) Act 2001 (NSW), was required to identify a specific error of law, fact, or discretion before intervening, or whether it could reassess the evidence independently.
  • Whether the prosecution had excluded, beyond reasonable doubt, the appellant's claim of self-defence under s 418 of the Crimes Act 1900 (NSW), specifically: (1) whether the appellant held a genuine belief that her actions were necessary to defend herself; and (2) whether the force used was a reasonable response in the circumstances as she perceived them.

Decision

Hatzistergos DCJ addressed the standard of appellate review at the outset. Drawing on AG v Director of Public Prosecutions (NSW) [2015] NSWCA 218, his Honour confirmed that the District Court is not confined to identifying a formal legal, factual, or discretionary error. The Court may exercise its powers based on its own assessment of the evidence, and the central question is whether the judgment under appeal is wrong and should be corrected.

On self-defence, the Court applied the two-limb test under s 418 of the Crimes Act. The prosecution bears the burden of excluding the defence beyond reasonable doubt. The first limb asks whether the defendant held a genuine belief that her conduct was necessary for self-defence; the second asks whether the force used was a reasonable response in the circumstances as she perceived them.

Hatzistergos DCJ found that the Local Court's treatment of the CCTV evidence, and its conclusions about the confrontation, did not adequately account for the appellant's version of events. His Honour accepted the appellant's account that the complainant was verbally aggressive, raised his arm, and escalated his behaviour, finding that this version was a reasonable possibility that the Crown had not excluded beyond reasonable doubt. Accordingly, the first limb of the self-defence test was satisfied.

On the second limb, the District Court found that the level and nature of force used by the appellant, assessed against the circumstances as she perceived them, had not been proved disproportionate beyond reasonable doubt. The conviction was set aside and a verdict of not guilty entered.

Orders Made

  • The appeal is allowed.
  • The orders of the Local Court are set aside.
  • The appellant is found not guilty.

Key Takeaways

  • The District Court confirmed on appeal that it is not required to identify a specific error of law, fact, or discretion before substituting its own verdict; it may conduct an independent assessment of the evidence under s 18 of the Crimes (Appeal and Review) Act 2001 (NSW).
  • A self-defence claim under s 418 of the Crimes Act 1900 (NSW) requires the prosecution to disprove, beyond reasonable doubt, both that the defendant genuinely believed the conduct was necessary and that the force used was a reasonable response in the circumstances as the defendant perceived them.
  • Where a defendant's version of a confrontation is a reasonable possibility on the evidence, the prosecution's failure to exclude that account beyond reasonable doubt is fatal to the conviction.
  • Credibility findings at first instance, particularly those adverse to a complainant with prior convictions for dishonesty offences and inconsistencies in testimony, informed the appellate court's reassessment of the competing accounts.
  • CCTV evidence does not always resolve contested factual questions definitively; the District Court here found that the footage did not exclude the appellant's account of the complainant's threatening conduct, notwithstanding the Local Court's contrary conclusions.
