The Crown sought a ruling on the admissibility of prior discreditable conduct to establish the accused's identity and provide narrative context in a criminal trial for uttering threats, impeding justice, and criminal harassment.
The accused, Lance Crossley, was self-represented with amicus curiae assistance.
The court applied the general principle that prior misconduct evidence is inadmissible to prove propensity but recognized exceptions for identity, narrative, and similar fact evidence, requiring relevance and a probative value outweighing prejudicial effect.
The court admitted evidence from March 2018 to February 2020, finding it inextricably linked to the current charges and highly probative of identity, motive, and intent, subject to limiting instructions.
However, incidents from 2016 and January 2018 were deemed too remote and prejudicial, thus inadmissible.
