That can be done by drafting.
You had two sets of concerns. You talked about drafting and you talked about the implementation. The drafting issue is one that we might be able to have addressed. In interests of time, I note that France has a section on torture in its criminal code, its penal code, and the state of Queensland has one, yet they're signatories to international conventions, as is Canada, so that doesn't seem to be a problem.
Could we give this the title that the sponsor of this bill wants by calling it not “torture”, but by saying something like “torturous assault” or something that would take it to another category on a gradient from “assault” to “aggravated assault” to “torturous assault”? Could that be a compromise?
