Citation: R v Bentley; R v Davies; R v Thomas; R v Tilley [2019] NSWSC 204
Court: Supreme Court of New South Wales
Date: 5 March 2019
Judge: Harrison J
Background
Four accused faced a retrial on a single count of murder following a prior trial in which the jury could not reach a unanimous or majority verdict on any count against any accused. The alleged murder arose from an incident on 31 March 2015 in South Windsor, in which the deceased was pursued, severely assaulted inside a shed, carried unconscious to a vehicle, and never seen again. The Crown's case at the first trial centred on a blunt force weapon, specifically an extendable baton later recovered from the shed.
On the first day of the retrial, the Crown sought leave to rely on an expert report from Detective Sergeant Moon, a forensic officer with bloodstain pattern analysis expertise. The report was dated 19 February 2019 and served on the accused only on 27 February 2019, approximately one week before the trial commenced.
The Crown conceded the report was served late and offered no explanation or extenuating circumstances to justify the delay.
Legal Issues
- Whether the Crown should be granted leave to rely on a late-served expert report at the commencement of a six-week murder trial
- Whether admission of the report would cause unfair prejudice to the accused
Decision
Harrison J refused the Crown's application to call Detective Sergeant Moon. The central concern was that the report expanded the Crown's case beyond its original hypothesis. At the first trial, the Crown's theory was that a blunt object, namely the extendable baton, caused the fatal injuries. Detective Moon's report introduced new opinions suggesting that a "large gushing type wound" was the most probable source of two substantial blood pools, and that incised wounds (cuts) or puncture wounds (stab wounds) were the two most common injury types consistent with that scenario. The report also identified a screwdriver found near the blood pools and opined that it may have been used as a weapon.
Harrison J acknowledged that some of the accused's concerns might be more apparent than real, given the volume of physical and scientific evidence already before the court. However, his Honour was not satisfied that admission of the report would avoid unfair prejudice to the accused. The court accepted that the accused could not, in the time available, reasonably obtain their own expert to respond to the new material.
Harrison J left open, without deciding, whether Detective Moon's opinions would actually qualify as expert opinion in the relevant sense, as no submissions were directed to that question.
Orders Made
The Crown's application to call Detective Moon as an expert witness was rejected.
Key Takeaways
- The Supreme Court refused to allow a late-served expert report to be tendered on the first day of a six-week murder retrial where the Crown conceded there was no explanation for the delay.
- A critical factor in the refusal was that the report went beyond the Crown's original case theory: whereas the first trial focused on blunt force injury from a baton, Detective Moon's report raised the possibility of stab or incised wounds and identified a screwdriver as a potential weapon.
- Where late expert material raises new case theories that the accused cannot reasonably respond to within the available time, the court found that admission would cause unfair prejudice to the accused.
- The decision confirms that the absence of any extenuating circumstances for late service significantly weakens the Crown's position when seeking leave to rely on expert evidence at the eleventh hour.
- Harrison J expressly declined to rule on whether Detective Moon's opinions met the threshold for admissible expert opinion, leaving that question open for another occasion.
