PDF Version: When Should Judicial Discretion Trump Expert Testimony?
Case Commented On: R v Clark, 2016 ABCA 72 (CanLII)
In Regina v Clark the Alberta Court of Appeal reinforced the principle that trial courts should enjoy broad discretion in making evidentiary decisions. On the other side of the scale in this particular case was the great problem of ensuring the accuracy of witness identifications when they are the primary basis for conviction. In the United States at least, 70% of exonerations obtained through DNA evidence occurred in cases involving eyewitness misidentifications (see data collected by the Innocence Project, available here).
Clark involved a trial by judge of a bank robbery case. During the crime the suspect had partially obscured his face with a hood and a hat pulled down over most of his features (at paras 3-4). At trial, the Crown relied on the testimony of three eyewitnesses, and in particular that of one woman who had stood about 5-6 feet away from him at the bank counter and glanced at him several times during the robbery at para 54). Several other witnesses identified a photograph of the robber taken from the security camera as an individual who went by the street name “Lips,” a name by which the accused had identified himself to a police officer prior to the robbery (at para 51).
