The Board must have primary regard to the following principles, as laid down in section 8 of the Long-term Prison Sentences Review Ordinance, Cap. 524, when exercising its functions or performing its duties in relation to a subject –
(a) in any case where the subject has not been completely rehabilitated, the rehabilitative effect of releasing the subject from detention before the unremitted part of his sentence is served;
(b) the benefits to the prisoner and to the community arising from the prisoner being supervised after release with a view to securing, or increasing the likelihood of securing, the prisoner’s rehabilitation (in any case where the prisoner has not been completely rehabilitated) and successful reintegration into the community;
(c) whether the part of the sentence of the subject already served is sufficient, in all the circumstances (in particular given the nature of the offence for which the subject is being detained), to warrant consideration being given to having the subject released from detention early;
(d) the need to protect members of the community from reasonably foreseeable harm that could be inflicted by the subject as a result of having been released from detention early.
