1 Application is made on behalf of Long Thanh Tran to exclude evidence taken from two video cameras outside the Salt Nightclub between 2.47 a.m. and 2.57 a.m. on 8 July 2002 which the Crown submits captures Long Tanh Tran's vehicle being parked outside the nightclub.
Videotape evidence and the risk of over-persuasion
2 The admission of video evidence taken from surveillance cameras is now commonplace.[1] Video evidence is highly persuasive because of the perception as to its reliability. Jurors will regard themselves as competent to interpret video evidence. Consequently there is a danger of uncritical acceptance by the jury when video evidence is employed. A jury may be persuaded that what the prosecution claims is clearly shown on the tape and give insufficient weight to contradictory evidence in more traditional forms.[2]
3 The discretion to exclude evidence will arise when it has been shown that the reception of the evidence will be unfair to the accused. In Ruling One[3] in the present trial I considered the relationship between the scope of the general discretion to exclude evidence which would be unfair to the accused and the "Christie" discretion to exclude evidence where its probative value was outweighed by its prejudicial effect. The degree of risk that the jury will attach more weight to such video evidence than is warranted in the circumstances will generally have to be assessed when reliance is placed upon the "Christie" discretion.
4 It may be accepted in the present case that the quality of the evidence is poor and does not reveal the make, model or colour of the vehicle. The video is not a continuous picture. There is some unknown interval of time which may be as much as a few seconds between each picture frame. The Crown concedes that the video does not enable any identification to be made of the vehicle or those who were using it. It is not in dispute that the video does not reveal the whole of the area in question. What the video shows is a vehicle driven to a spot adjacent to a garage roller door where it is parked. Later, persons are observable walking to the rear of the vehicle and the boot can be seen to be opened. The men are seen to return to the vicinity of the front of the nightclub and the vehicle is subsequently driven away. The time that each of these events occur is recorded on the video.
5 Mr Mullaly, on behalf of Long Thanh Tran, submits that I should exercise the discretion to exclude this evidence because it is conducive to the drawing of false or misleading conclusions. Any probative effect of the evidence is said to be outweighed by its unfair prejudicial effect. Reliance is placed upon the judgment of Ormiston J in R v Harris[4] (No. 3) and passages from the judgment of McHugh J in Festa v R[5]. In substance it is contended that the jury is likely to give greater weight to the video evidence than it deserves.
6 In Harris Ormiston J excluded evidence of voice identification because there was so much suggestive prejudicial material involved in the voice identification that could not be removed by cross-examination. It was the "means adopted" in making the voice identification which was unsatisfactory, so that the identification may have "irrationally impressed" the jury and led to a wrong conclusion.
7 The video evidence does not directly implicate the accused in the crime. It is proof of a circumstance that, with other evidence, may establish that it was Long Thanh Tran's car. This fact, in conjunction with what the two men are observed to do on the video and other circumstantial evidence, may support the conclusion that the accused was complicit in the crime charged.
8 A recent example of the proper admission of surveillance video evidence is that of R v Arden.[6] In that case the Court of Appeal rejected the contention that the trial judge ought not to have admitted surveillance video into evidence because the quality of the video was unsatisfactory and incapable of providing identification evidence upon which a jury could safely act. The Court of Appeal did not consider that the video was relied upon to prove identification of the appellant. It was one item in a range of evidence upon which the jury could reach a conclusion that the appellant must have been one of those depicted in it.
9 Some of the issues in that case are not dissimilar to those in the present one. The video provided the approximate time of the attack. The account given by the applicant to investigators meant that even if the jury could not positively identify the applicant from the video, they could, by using his account and the video, conclude that the journey he described must have been the same as the one the complainants described.
