In order to activate this clause, it presupposes that the medical practitioner or physician who is contemplating performing the medical assistance in dying would recognize that. I think if they recognize that this person has a mental condition, as part of their own due diligence they would seek this kind of clarification as a matter of course. I think the amendment is redundant, and I will not support it.
