37 At page 55 Gleeson CJ confirmed the views which he had expressed in Engert (1998) 84 A Crim R 67. There, the Chief Justice, after pointing out that the interplay of Ca consideration relevant to sentencing may be complex and on occasions even intricate (page 68), continued at p 71:
"In truth however ... the question of the relationship, if any, between the mental disorder and the commission of the offence, goes to circumstances of the individual case to be taken into account in the application of the relevant principles. The existence of such a causal relationship in a particular case does not automatically produce the result that the offender will receive a lesser sentence, any more than the absence of such a causal connection produces the automatic result that an offender will not receive a lesser sentence in a particular case. For example, the existence of a causal connection between the mental disorder and the offence might reduce the importance of general deterrence, and increase the importance of particular deterrence or of the need to protect the public. By the same token, there may be a case in which there is an absence of connection between the mental disorder and the commission of the offence for which a person is being sentenced, but the mental disorder may be very important to considerations of rehabilitation, or the need for treatment outside the prison system."
