Citation: R v Mitchison; R v Wells; R v Whelan [2016] NSWSC 463
Court: Supreme Court of New South Wales
Date: 30 March 2016
Judge(s): R A Hulme J
Background
Three accused were charged jointly with the murder of a 50-year-old man at East Maitland on 15–16 March 2014. The Crown alleged a joint criminal enterprise among the accused to inflict violence on the deceased, with the foreseeable possibility of grievous bodily harm resulting. The deceased died approximately ten days after sustaining a traumatic subarachnoid haemorrhage.
The accused included the deceased's partner, her adult son, and her son's friend. The Crown's case rested on competing accounts given by the accused to police and evidence from a neighbour, who came to investigate the disturbance and was himself assaulted during the incident.
Two preliminary issues arose before trial: a separate trial application by one accused, and an objection by another accused to the admissibility of evidence concerning the assault on the neighbour.
Legal Issues
- Whether one accused was entitled to a separate trial on the ground that evidence admissible only against co-accused would cause him irreparable prejudice before a joint jury.
- Whether evidence that one accused assaulted a neighbour (an uncharged act) was relevant to the Crown case and admissible at trial, or whether it was irrelevant and unfairly prejudicial.
Decision
Separate trial application: Hulme J refused the application for a separate trial. His Honour accepted that some evidence was admissible against the co-accused but not against the applicant, and that this created a theoretical risk of prejudice. However, the court was satisfied that carefully crafted jury directions could adequately address any risk of unfair prejudice. The applicant had not demonstrated that the prejudice was so significant or irremediable as to require the cost and inefficiency of separate proceedings. The prospect of inconsistent verdicts from separate juries on what was substantially the same factual matrix was also a relevant consideration weighing against separation.
Admissibility of the neighbour's evidence: Hulme J ruled that evidence of the assault on the neighbour was admissible. On the neighbour's account, the assault was inextricably linked to the narrative of the events surrounding the deceased's death, qualifying it as transactional evidence (sometimes called "res gestae" evidence: evidence of surrounding acts so connected to the offence that they cannot be meaningfully separated from it). Separately, the evidence was relevant to the state of mind of the accused at the time of the alleged assault on the deceased, given that he had arrived at the home after seeing the deceased's partner with black eyes and hearing her say she wanted the deceased out of the house. His Honour left open the possibility of a direction to the jury to avoid tendency reasoning, and indicated he would hear submissions on that question at an appropriate time.
Orders Made
- The application by the accused Mitchison for a separate trial was refused.
- The objection to the admissibility of Mr Mallinson's evidence regarding the assault on him was dismissed; the evidence was ruled admissible.
Key Takeaways
- A separate trial application will not succeed simply because some evidence is admissible against co-accused but not the applicant; the court must be satisfied that jury directions cannot adequately cure the prejudice.
- The risk of inconsistent verdicts from separate juries dealing with the same facts is a relevant factor weighing against granting a separate trial.
- Transactional evidence (evidence of acts so closely connected to the alleged offence that the two cannot be separated) remains admissible even where those acts constitute uncharged conduct by the accused.
- Evidence of an uncharged assault on a third party can be relevant to an accused's state of mind at the time of the principal offence, independent of any tendency reasoning, where the circumstances surrounding both acts are closely connected.
- Where tendency reasoning is a potential concern arising from the admission of uncharged-act evidence, a limiting direction to the jury may provide an appropriate safeguard; the Supreme Court indicated it would entertain submissions on that issue before it arose at trial.
