During a criminal jury trial, the accused objected to the Crown's expert witnesses using PowerPoint presentations that included conclusions and opinions, arguing they would unfairly emphasize the Crown's case and act as written reports.
The trial judge ruled that the PowerPoint presentations were admissible as exhibits to assist the jury in understanding complex technical evidence, provided that certain bald conclusions or opinions were redacted.
The judge found that such demonstrative aids are reasonably necessary in modern trials to enhance juror comprehension, subject to proper limiting instructions.
