[26] The respondent formed the view that the applicant was an unacceptable risk to the community. The nature of that risk was the risk of his re-offending. The finding that the risk was "unacceptable" was necessarily a value judgment for which there were several relevant considerations. One of them, but not the only one, was the need to protect the community. According to the Guidelines, this consideration was to be given "the highest priority". But again according to those Guidelines, it was not to be the only consideration. Clearly, there was the consideration of the interests of the prisoner. But there was also to be considered the public interest in the fair operation of a regime for parole, because in general, a real rather than theoretical availability of parole is conducive to the rehabilitation of prisoners and to the orderly management of prisons. An express object of the CSA is for "community safety and crime prevention through humane containment, supervision and rehabilitation": s 3(1). The public is protected by the rehabilitation of offenders as well as by their incarceration. Each of those considerations and perhaps others would be expected to affect the value judgment involved in assessing the risk to the community from a prisoner's parole as acceptable or otherwise. And that judgment might be affected according to whether there was a real prospect that the prisoner's circumstances could change with the result of lessening his risk of re-offending. It might also be affected according to whether the prisoner was able to influence those circumstances. Accordingly, it cannot be safely concluded in this case that parole would have been refused had the respondent considered the applicant's argument as to re-classification and accepted it.
