In the case of R v Ewanchuk, what must the accused present to support their defense?

In R v Ewanchuk, the central issue revolved around the concept of "honest but mistaken belief" in consent as a defense in sexual assault cases. For the accused to successfully argue this defense, they must demonstrate that they genuinely believed that the complainant was consenting to the act, even if that belief is ultimately mistaken. This belief must be honest and reasonable under the circumstances presented.

The court emphasized that the accused's subjective perception of the situation is critical. It does not suffice for the accused to claim a mere misunderstanding; rather, the focus is on the authenticity of their belief regarding consent.
