Supreme Court 7 July 2025

R v Huber

[2025] NSWSC 714

Homicide

Citation: R v Huber [2025] NSWSC 714
Court: Supreme Court of New South Wales
Date: 7 July 2025
Judge: Rothman J

Background

The accused was charged on indictment with three offences arising from events in the Ballina region in late 2022 and early January 2023. The first charge, assault occasioning actual bodily harm against the deceased on 26 December 2022, was the subject of a guilty plea and was set aside for sentencing. The second and third charges were murder and manslaughter, respectively, both arising from events on 3 January 2023 that resulted in the death of the deceased.

The trial proceeded before Rothman J sitting alone, pursuant to s 133 of the Criminal Procedure Act 1986 (NSW). The accused denied having touched the deceased, making that denial informally on bodycam footage and otherwise exercising his right to silence.

The case involved a genuinely contested medical picture. Experts disagreed about the precise cause and mechanism of death, with potential contributing factors including methadone overdose, commotio medullaris (a spinal cord concussion-type event), positional asphyxiation, and axonal injury. The matter arose in a domestic violence context.

  • Whether the Crown proved beyond reasonable doubt that the accused's act was an operating and substantial cause of the deceased's death, given expert disagreement about the medical mechanism of death
  • Whether the Crown proved beyond reasonable doubt that the accused acted with the requisite intention to kill or to inflict grievous bodily harm, so as to establish murder under s 18(1)(a) of the Crimes Act 1900 (NSW)
  • Whether, if murder was not established, the elements of manslaughter under s 18(1)(b) were made out, specifically whether the accused committed a deliberate, unlawful, and dangerous act that was an operating and substantial cause of death
  • The distinction between "cause of death" and "mechanism of death" in the context of circumstantial evidence and competing expert opinions

Decision

Rothman J was not satisfied beyond reasonable doubt that the accused had the requisite intention to kill or to cause grievous bodily harm. The judgment draws a clear distinction between a deliberate act (one that is voluntary and willed) and the specific mental state required for murder. Although intention can be inferred from conduct, the Crown must establish the accused's actual subjective intent at the time of the fatal act. On the evidence as a whole, the Crown did not satisfy that standard, and the accused was acquitted of murder.

On the manslaughter charge, however, the Court was satisfied beyond reasonable doubt that all necessary elements were established. The accused performed a deliberate and unlawful act, and a reasonable person in the accused's position would have appreciated that the act exposed the deceased to an appreciable risk of serious injury. Proof of any specific intent to injure was not required for this finding.

The causation question was addressed against a background of competing expert evidence about the medical mechanism of death, including the roles potentially played by methadone toxicity, spinal cord injury, positional asphyxiation, and axonal injury. The Court distinguished between the cause of death (the accused's assault) and the precise medical mechanism by which death resulted. Despite expert disagreement about mechanism, the Court was satisfied that the accused's act was an operating and substantial cause of the deceased's death.

The judgment also sets out, in terms required for a judge-alone trial under s 133, the applicable directions and warnings that would ordinarily be given to a jury, including the standard of proof, the presumption of innocence, the right to silence, and the approach to drawing inferences from circumstantial evidence.

Orders Made

  • The accused was found not guilty of murder (Count 2) contrary to s 18(1)(a) of the Crimes Act 1900 (NSW)
  • The accused was found guilty of manslaughter (Count 3) contrary to s 18(1)(b) of the Crimes Act 1900 (NSW)
  • A sentencing hearing in relation to Count 1 (assault occasioning actual bodily harm, guilty plea) and Count 3 (manslaughter, guilty verdict) is to be listed after consultation with the parties

Key Takeaways

  • Murder under s 18(1)(a) of the Crimes Act 1900 (NSW) requires proof beyond reasonable doubt of the accused's subjective intention, at the time of the act, to kill or inflict grievous bodily harm. That intention must be distinguished from the mere voluntariness of the act and does not require premeditation.
  • Manslaughter by unlawful and dangerous act does not require proof of any intent to injure. The Crown need only establish that a reasonable person in the accused's position would have recognised an appreciable risk of serious injury arising from the deliberate application of force.
  • Where medical experts disagree about the mechanism of death, a conviction may still be open if the court is satisfied beyond reasonable doubt that the accused's act was an operating and substantial cause of death. Cause of death and mechanism of death are legally distinct concepts.
  • In a judge-alone trial under s 133 of the Criminal Procedure Act 1986 (NSW), the judicial officer must apply the same directions and warnings that would be given to a jury, with the reasoning process made transparent through written reasons.
  • An accused's exercise of the right to silence, and an informal denial captured on bodycam, cannot be used to draw adverse inferences against the accused, and place no onus on the defence to disprove any element of the offence.
