[COUNSEL]: Just coming back to this motive, you are aware of the account given by her to Dr Leach at the Box Hill Hospital that her husband had told her he regretted having children?
[WITNESS]: Yes
[COUNSEL: You are aware of a comment to Louise Mitchell that she was upset by Thomas saying he wanted to be with his father?
[WITNESS]: Yes
[COUNSEL]: And you are aware of the proximity to Father's Day in relation to these events?
[WITNESS]: Yes
[COUNSEL]: Do they have a bearing, as far as you can see, on her motivation in relation to this?
[WITNESS]: She also made statements about this being the last Father's Day she would spend - sorry, that Mr Fitchett would spend with his children. Obviously I had to consider a range of possibilities for these events but the facts that you have led there to me don't necessarily indicate that the actions were punitive. That was one of the readings which I think one could take of a number of statements about Mr Fitchett, but there were other statements surrounding those ones, for instance, to Dr Leach, indicating that her children were safe and so forth which I thought cast a different light on those statements.
[COUNSEL]: Thank you. Just finally, Doctor, this appears to be a particularly difficult case owing to the lack of psychotic condition; would you agree with that?
[WITNESS]: Difficulty (sic) in what sense?
[COUNSEL]: Difficult from your point of view in relation to a jury ascertaining mental impairment or no mental impairment?
[WITNESS]: Certainly the grounds for a mental impairment defence are frequently significant brain injuries or intellectual disability or psychotic illnesses, but the test is not specifically defined that there must be a psychotic illness present. It goes instead to disorders of thinking and although there were no overt psychotic symptoms, the waiting and prioritising that Ms Fitchett gave to a range of aspects of her life at the time to me were gravely irrational, so awaiting that, for instance, that her children would be better off dead than being in the care of her husband, to me is an irrational thought which although not psychotic clearly indicates an inability to reason at the time.[8]
