The Crown sought to admit evidence of the accused's prior discreditable conduct, including violent sexual images, search terms, and viva voce evidence of consensual choking sex, in a first-degree murder trial.
The defence intended to assert an alternate suspect (James Gardiner) and an inadequate police investigation defence.
The court ruled that the discreditable conduct evidence was not admissible generally, as its prejudicial effect outweighed its probative value, not being sufficiently distinctive to constitute a signature.
However, the evidence would become admissible if the defence adduced evidence of the alternate suspect's bad character or raised an inadequate investigation/tunnel vision defence, to prevent a distorted picture for the jury.
Certain highly prejudicial evidence, such as a specific video, would need to be excised or altered if admitted.
