In a judge-alone first-degree murder trial, the Crown sought to admit discreditable conduct evidence from former sexual partners, acquaintances, and material found on the accused's electronic devices to support an inference of violent sexual propensity relevant to the alleged murder during sexual assault or unlawful confinement.
Applying the similar fact evidence framework, the court held that the proposed evidence showed, at most, an interest in BDSM activities including choking, with significant consensual components, and did not establish a specific propensity to engage in non-consensual violent sexual conduct as alleged.
The court found the inferential chain from prior consensual or mixed sexual practices to the charged non-consensual homicidal conduct was logically flawed and insufficiently probative of the actus reus of first-degree murder.
The application was dismissed, and the court added that any limited probative value would in any event have been outweighed by prejudice through distraction from the core trial issues.
