Establishing whether your client has a Mental Impairment Defence available

Eligibility for a Mental Impairment defence after a person has been charged with a criminal offence requires two elements. Firstly, the person must be diagnosed with a mental disorder of a kind that the law recognises to be a ‘mental impairment’ (previously known as ‘disease of the mind’). Getting into one’s mind could be considered as a form of art, so check this out Second, at the time of the conduct comprising the alleged offence, the manifestations of that disorder (such as delusional thinking) must have been of such a severity that the person either did not know the nature and quality of their actions, or (more commonly) was unable to reason “with a moderate degree of sense and composure” as to whether another (“reasonable”) person would consider that conduct to be wrongful.

In practice, this requires careful consideration of evidence relating to the person’s prior mental health history and their mental state and behaviour at the time of the alleged offence and its aftermath.
