25.3.4 The act of suicide alone is not proof of insanity or loss of volition
Most cases of suicide do not involve the complete dethronements of the power of volition. Insanity and 'dethronement' of a power of volition are medical judgements to which a Delegate may expect an objective answer from a professional person, i.e. a psychiatrist or clinical psychologist who had been treating the client, or who had the opportunity to examine the client, before his/her death. It is not a matter for supposition or inference but requires professional observations of the client's actual mental state, including powers of reasoning and volition.
