CRIMINAL LAW GENERAL MATTERS CRIMINAL LIABILITY CAUSATION

Citation: Swan v R [2018] NSWCCA 260
Court: Court of Criminal Appeal, NSW
Date: 23 November 2018
Judges: Bathurst CJ; Hoeben CJ at CL; R A Hulme J

Background

The appellant was convicted of murder following a violent home invasion in which a 78-year-old man was severely beaten. The victim was hospitalised for over four months before being transferred to a nursing home. He deteriorated further, was readmitted to hospital in December 2013, and died on 10 December 2013, approximately eight months after the assault.

The direct medical cause of death was respiratory failure caused by fat emboli in the lungs, which arose from an untreated fracture to the victim's left femur. The central dispute at trial was what caused the fracture. The prosecution argued it resulted from a fall linked to the victim's declining health after the assault. The defence argued it was caused by the spread (metastasis) of a kidney tumour, breaking the chain of causation between the assault and the death.

The prosecution's closing address introduced an additional pathway: even if the fracture was caused by the tumour, the decision not to operate on the fracture (which led to the fatal fat emboli) was itself caused by the victim's poor physical state resulting from the assault. The appellant argued on appeal that this line of reasoning was unsupported by the evidence and constituted a miscarriage of justice.

  • Whether the prosecution's closing address invited the jury to reason along a path that was not properly open on the evidence
  • Whether the assault could still be regarded as a substantial or significant cause of the victim's death, even if the femur fracture was caused by tumour metastasis rather than by a fall
  • Whether any intervening event (such as the tumour or its metastasis) broke the chain of causation between the assault and the death

Decision

The Court of Criminal Appeal unanimously dismissed the appeal, granting leave to appeal but finding no miscarriage of justice. Bathurst CJ, with whom Hoeben CJ at CL and R A Hulme J agreed, held that both prosecution pathways were open on the evidence.

On the causation question, the Court applied the principle from Royall v The Queen that it is sufficient for the prosecution to establish that the accused's conduct was a "substantial or significant cause" of death. The assault did not need to be the sole cause. The Court found the jury was entitled to be satisfied of this standard regardless of whether the fracture arose from a fall or from the tumour.

The Court reasoned that the critical issue was not what caused the fracture, but why the fracture went untreated. The evidence showed that the victim's condition had deteriorated so severely as a result of the assault that surgical intervention was ruled out. A decision to place him on a "not for resuscitation" or palliative pathway had been made at St Vincent's Hospital, and that earlier decision was expressly referenced when surgeons at Prince of Wales Hospital decided not to operate. This chain of medical decision-making flowed from the injuries sustained during the assault.

Even accepting the possibility of a pathological fracture caused by the tumour, the Court held the tumour metastasis would not constitute an intervening event sufficient to break the chain of causation. The assault remained a substantial or significant cause of death because the inability to treat the fracture was directly attributable to the victim's assault-related condition, not to the tumour itself or its cause.

Orders Made

  • Leave to appeal granted
  • Appeal dismissed

Key Takeaways

  • The Court of Criminal Appeal confirmed that, in a murder prosecution, it is sufficient for the Crown to establish that the accused's act was a "substantial or significant cause" of the victim's death; it need not be the sole cause.
  • Where an intervening medical condition exists, the question is whether that condition truly broke the chain of causation. Here, the Court found that tumour metastasis did not sever the causal link because the inability to treat its consequence (the fracture) was itself attributable to the assault.
  • A prosecution closing address does not constitute a miscarriage of justice merely because it articulates an alternative causation pathway, provided that pathway is supported by evidence adduced at trial.
  • Sufficient evidence existed for the jury to infer that medical decisions made late in the victim's life, including the decision not to operate on the fracture, traced back to injuries inflicted during the initial assault.
  • Broad civil law principles of causation apply in criminal cases, though the standard of proof differs: the Crown must establish causation beyond reasonable doubt, and the moral culpability of the accused is the focus of the inquiry.
