This is where the charter jurisprudence is complex relative to other forms of criminal law. You're quite right to say that it's the accused who faces a deprivation of their liberty as a result of the trial.
What the court has said repeatedly in many cases is that the accused's right to full answer in defence and the other charter rights that are associated with their particular position of vulnerability are partly delineated and delimited by the charter rights of the complainant in a sexual assault trial, specifically because of the equality concerns that arise, the history of the operation of myths and stereotypes, and the concerns about the accuracy of truth seeking in a system that has developed over time, unfortunately, through the perpetuation of myths and stereotypes. It's a recognition that these cases are different, which has been a very clear and consistent thread in the Supreme Court of Canada's jurisprudence.
I think it is crucial to emphasize and indeed to hold both Parliament and courts to account to the proposition that the Supreme Court of Canada has been clear on this. Yes, the accused have fair trial rights and they absolutely need to be respected. But part of respecting those is about thinking very carefully about the charter rights of complainants and about how those two things can be maximized ideally, or when they come into conflict, how that conflict can be resolved in the best possible fashion, thinking about other social objectives such as truth seeking and such as the public interest in the prosecution of crime.
