It is unclear exactly which legal framework should be used: the Mental Capacity Act 2005 or the Mental Health Acts 1983 and 2007.
The source of the difficulty
The fundamental questions about anyone's ‘abnormal’ behaviour are as follows:
Is the behaviour consciously and deliberately controlled? Or
Does the person have a disorder of
