Summary

This interlocutory appeal raises questions of general importance about the admissibility of expert scientific evidence. At issue in the appeal is the reliability of DNA evidence which utilises a relatively new statistical methodology. Two key questions arise, as follows:

(a) is reliability a criterion of admissibility of opinion evidence under s 79(1) of the Evidence Act 2008 (the ‘Act’), or is reliability to be assessed in deciding whether the evidence should be excluded (under s 135 or s 137); and

(b) by what criteria is the reliability of expert scientific evidence to be assessed?

The applicant has been charged with aggravated burglary, rape, indecent assault and intentionally causing injury. Expert opinion evidence is to be called at the trial about the analysis of DNA samples from the crime scene and what are said to be the similarities between those samples and a DNA sample provided by the applicant following an unrelated conviction.

The DNA evidence is to be presented in the usual form of a ‘likelihood ratio’.[1] That is, for each DNA sample where the suspect cannot be excluded as a contributor, a ratio is calculated which shows how much more likely it is that the suspect was the source of the DNA (or a contributor to it) than that some other person chosen at random from the population was the source (or a contributor).
[1]See R v Berry (2007) 17 VR 153, 161 [30] (‘Berry’).

In this case, the likelihood ratios have been calculated using a recently-developed software package, known as STRmix, which was introduced into Victoria in March 2013.…

Grounds of appeal

[14] The appellant contends that the primary judge erred in finding that the respondent had discharged the onus of establishing the matters required under the relevant provision.

[15] It was submitted that his Honour failed to give adequate weight to the evidence of the second witness, and that the findings of fact were not reasonably open on the material before the Court.

[16] The respondent, for its part, submits that no error is disclosed, and that the conclusions reached were well within the range of outcomes available to the primary judge.

Consideration

[17] It is convenient to deal first with the question of construction, as the resolution of that issue informs the remaining grounds advanced by the appellant.

[18] For the reasons that follow, we are of the view that the appeal should be allowed in part and the matter remitted for further determination.

Case: [2015] VSCA 148
Decision Date: 12 June 2015

CaseChat Overview and Summary

In the case of Tuite v The Queen, the appellant challenged the conviction on the grounds of the admissibility of certain forensic evidence presented at trial. The appellant argued that the statistical methodology used to analyse DNA samples was not reliable and therefore should not have been admitted under the Evidence Act 2008. The High Court of Australia was tasked with determining the admissibility of expert forensic evidence, particularly the use of new statistical methodologies in DNA analysis, and whether these methods were sufficiently reliable and generally accepted within the scientific community.

The primary legal issue before the Court was whether the trial judge correctly admitted the expert evidence based on a novel statistical methodology for interpreting DNA samples. The Court had to consider the statutory framework under the Evidence Act 2008, particularly sections 79(1) and 137, which govern the admissibility of opinion evidence and the balancing of probative value against the risk of unfair prejudice. Additionally, the Court needed to interpret the term 'specialised knowledge' to determine if there was an implied requirement for evidentiary reliability and whether this knowledge must be accepted or established within the relevant field.

The Court held that the trial judge's decision to admit the expert evidence was open, meaning it was a permissible conclusion given the circumstances. The Court found that the statistical methodology, while new, was based on sound principles and had been appropriately validated. It also noted that the probative value of the evidence outweighed any danger of unfair prejudice. The Court applied the principles from Honeysett v The Queen, clarifying that 'specialised knowledge' does not necessarily require the field of knowledge to be universally accepted, as long as it is based on good grounds. The Court distinguished the Daubert test, emphasising that Australian law does not require an implied evidentiary reliability threshold.

The appeal was dismissed, affirming the lower court's decision to admit the expert forensic evidence. The Court's ruling underscored the importance of the context and validation of new statistical methodologies in forensic science, affirming the trial judge's exercise of discretion in admitting the evidence.
