"43. This is a case in which, on the available evidence, a sentencing court could properly have reached a conclusion that Pt 10 of the Act should be applied. On the other hand, there were important considerations of proportionality militating against such a conclusion. These included (1) the absence of any major criminal convictions, notably for any acts of violence, prior to the subject offences; (2) the appellant's pleas of guilty; (3) the fact that the subject charges, although extremely serious, all related to events that occurred within an interval of nine months and involved three happenings. The details of the sexual activities with animals were unproved. They had never been the subject of any criminal charges under the Code[15]. The appellant was not to be punished additionally in respect of those events[16]. Any feelings of distaste or revulsion concerning such activities should not enter into the sentencing process. The reasoning of the sentencing judge did not deal with the issues, including issues of predictability, involved in deciding why a sentence of 22 years should not have been imposed, having regard to relevant sentencing considerations, including the need to protect the community. One of the matters of particular difficulty in a case such as the present is the uncertainty that is necessarily involved in estimating the danger to the community of a person who, on any view, will be incarcerated for such a long time. The operation of the parole system, and the possibility of treatment while in prison, are matters that call for close attention. In a particular case, it may be that the system of review under Pt 10 provides the only appropriate method of relating the interests of the community to the requirements of justice to an individual offender. Nevertheless, the protective potential of the ordinary sentencing regime needs to be examined first and most closely before deciding to depart from it. Another difficulty raised by the present case, addressed in some detail by the psychiatrists, but referred to only briefly and without analysis in the reasons for sentence, is the relationship between the appellant's paraphilia and the level of risk that he would be likely to present in, say, 20 years time."
