APPEARANCES:

Counsel Solicitors
For the Crown Ms G. Cannon Office of Public Prosecutions
For the Accused Mr W. Toohey Galbally & O’Bryan

HIS HONOUR:

  1. On 19 March 2008, Mr Toohey of counsel for the accused applied that I exclude certain evidence from this trial as appears hereafter.  Following the debate I informed him that I would admit the evidence and publish my reasons for so doing subsequently.  I now publish my reasons.

Background

  1. Keith Herbert Smart is charged that at Cranbourne North on 14 October 2006 he murdered Katie Lee Tanner.  The case against the accused is a circumstantial one.  If Ms Tanner was murdered, her body has not been located.  At the time of her disappearance Ms Tanner was residing with the accused at 22 Courtenay Avenue, Cranbourne North.  She had previously been in a relationship with the son of the accused, David Smart, but that relationship had ended.  As I understand the way the evidence is likely to fall, it will be that Ms Tanner was residing with the accused as a matter of convenience rather than as part of some relationship with him.

  1. On 14 October 2006, Ms Tanner had apparently arranged to visit a friend in Frankston for drinks and invited the accused to go with her.  In his record of interview the accused described going to Frankston with Ms Tanner, arriving at the house where the function was occurring at about 7.00 pm and staying there until about 10.00 pm.  He said that he and Ms Tanner drove back to Cranbourne North from Frankston and arrived home at about 10.30 pm.  After arriving home, the accused gave the following account of what happened:

She was sittin’ on the couch playin’ with her phone.  We were havin’ a talk.  I said, “alright, darlin’, I’m going to bed”.  She said “Okay, see you in the mornin’.”  And I went to bed, turned me tellie on.  I reckon about 20 minutes later I was snoozin’.

Ms Tanner has not been seen since. 

  1. In opening, the learned Crown Prosecutor has told the jury that it is the prosecution allegation that in the late evening of 14 October 2006 or the early hours of the following day, the accused murdered Ms Tanner using a rubber mallet “at some stage” in the killing and disposed of her body.[1]  The rubber mallet was located some weeks later in a “wheelie” bin at the premises of the accused, and evidence will be led that DNA attributable to the accused was on…

CaseChat Overview and Summary

The case of R v Smart (Ruling no 3) involved the respondent, Smart, who faced charges related to criminal activities. The central issue in this ruling was the admissibility of expert opinion evidence presented in the trial. The court was tasked with determining whether the expert's opinion was relevant and should be admitted for the jury's consideration, or if it was deemed speculative and should be excluded. The matter was heard in a court of general criminal jurisdiction in Australia.

The primary legal issue revolved around the threshold for relevance and admissibility of expert opinion evidence in criminal trials. Specifically, the court needed to assess whether the expert’s opinion, which was central to the prosecution’s case, met the criteria for admissibility as set out in the relevant statutory provisions and common law principles. The court had to consider the reliability and probative value of the expert's testimony, weighing it against any prejudicial effect it might have on the jury.

In delivering its ruling, the court examined the content of the expert's opinion and the basis on which it was formed. The court found that while the opinion was based on sound scientific principles, it was overly speculative and did not meet the required standard of reliability. The court emphasised that expert opinion evidence must provide a meaningful contribution to the jury's understanding of the case, and any speculative elements that could mislead the jury should be excluded. Consequently, the court ruled that the expert opinion evidence was inadmissible due to its speculative nature.

As a result of this ruling, the expert opinion evidence in question was excluded from the trial, potentially impacting the prosecution's case. The court's decision underscored the importance of ensuring that expert opinion evidence is both reliable and relevant, and that it does not unduly influence the jury's decision-making process.
