This pre-trial motion addressed the Crown's application to introduce evidence of prior discreditable conduct against the accused, Joshua Barreira and Chad Davidson, in a first-degree murder trial.
The court applied the R. v. Handy framework, balancing the probative value against the prejudicial effect of each piece of evidence.
For Joshua Barreira, evidence of his suspended driver's license, drug trafficking proximate to the murder, criminal associations with co-accused, and dreams about the deceased was admitted as part of the narrative or to rebut innocent association.
However, evidence of his general marijuana use, past drug financing, owning a 'crack house,' prior jail records with Davidson, and specific past convictions for firearms and counsel to commit murder were deemed inadmissible due to higher prejudicial effect or lack of probative value.
For Chad Davidson, evidence of his criminal associations with the Barreira family, admissions to Marta Leite regarding the murder, and specific photos for identification purposes were admitted.
Conversely, allegations of a past home invasion, certain tattoo evidence (handguns, 'NMIF'), an uncontextualized admission to a fellow inmate, and his armed robbery conviction were excluded.
The court emphasized the importance of narrative evidence and rebutting innocent association while strictly scrutinizing evidence for propensity.
