"The effect of what I would favour by way of re-sentencing on the substantive matters means that the [appellant] will serve 5 years in custody; and, if not granted parole, 7 years in custody. He cannot be released, therefore, before October 2005; and possibly October 2007. A concurrent sentence, passed pursuant to the Habitual Criminals Act, of 8 years, would extend until October 2008, the period of the appellant's detention. A sentence of that order, with such consequences, is in my opinion justly proportioned to the circumstances of the [appellant's] case. The [appellant's] condition is, by any reasonable reckoning, a difficult and troubling one. It requires careful and sensitive on-going monitoring and treatment. The [appellant], however he might be released back into the general community, will need some very careful ongoing supervision. The effect of the sentence passed pursuant to the Habitual Criminals Act will give the relevant authorities some added flexibility in assessing whether, and when, and upon what basis, the [appellant] is to be returned into the general community. It might very well be that, in due course, it will be obvious that the only fair way of dealing with the [appellant] is by taking steps, if it is possible to do so, to have him dealt with as some kind of forensic patient pursuant to the relevant mental health legislation. No doubt matters of that character cannot be rushed; but, if there is to be purely preventive detention at all of the [appellant], then it must be a matter of course that the period of such purely preventive detention is to be the minimum which the evidence suggests will be sufficient to enable the Corrective Services authorities, and the Prison Medical authorities to deal in a properly humane fashion with this [appellant]."
