This ruling addresses applications by co-accused David Obregon Castro and Sarai Lopez-Iglesias in a first-degree murder trial to adduce evidence of each other's prior discreditable conduct, given their "cutthroat" defences.
The court applies the balancing test for admissibility of co-accused bad character evidence, which is less stringent than for Crown-led evidence.
Ms. Lopez-Iglesias was permitted to introduce evidence relevant to her state of mind (fear of Obregon Castro), his propensity to commit the crime, and his credibility, including details of the "Z Bar Incident" (shooting), the assault on "Chips" (stabbing), various assaults she suffered from Obregon Castro, and his alleged gang membership (limited to her state of mind).
However, evidence of Obregon Castro's past arson/attempted murder charge (acquitted), claims of torturing "snitches," sexual assault, threats regarding Kyle Watts, a plan to shoot a pawn shop owner, and preliminary inquiry observers was deemed inadmissible due to low probative value outweighed by prejudicial effect.
Mr. Obregon Castro was also allowed to adduce evidence of Ms. Lopez-Iglesias's violence towards him, drug use, and participation in bank frauds to challenge her credibility, but not evidence of trafficking sex workers.
The judge emphasized the necessity of detailed limiting instructions to the jury regarding the use of such evidence.
