"I do that, Harlow, not contemplating that you will spend the rest of your life in prison. I do not do it for that reason. I do it, if I may put it in this rather strange way, out of humanity to you, so that your case may be kept under continual review, as it would be. If I had to determine a fixed length of imprisonment, in order to protect the public, it would be so long as to deny you any hope at all, and it may well be unjust to you. I hope you can understand that. At least if I sentence you in the way I do, it will be somebody's responsibility -- which I believe and hope they will dutifully carry out -- to keep the length of time which it is appropriate for you to spend in prison under continual review, so that you may be released from the sentence as soon as it is judged safe that you should be."
"10. Pursuant to section 32(6) of the 1991 Act (now section 239(6) of the 2003 Act), the Secretary of State has issued directions to the board in relation to the release and recall of life sentence prisoners. Direction 6 provides: 'In assessing the level of risk to life and limb presented by a lifer, the Parole Board shall consider the following information, where relevant and where available, before directing the lifer's release, recognising that the weight and relevance attached to particular information may vary according to the circumstances of the case .... (d) whether the lifer has made positive and successful efforts to address the attitudes and behaviour problems which led to the commission of the index offence .... (h) the lifer's awareness of the impact of the index offence, particularly in relation to the victim or victim's family, and the extent of any demonstrable insight into his/her attitudes and behavioural problems and whether he/she has taken steps to reduce risk through the achievement of life sentence plan targets ....'"
"45. .... This court must thus determine, on the evidence before this court, whether this is a case where the evidence shows that, by reason of failures in the system, it is not possible to determine whether he is dangerous or not. I appreciate that there will be an overlap evidentially: the Parole Board may not be satisfied because of absence of material, of the conditions which alone permit release for the purposes of section 28(5). But that evidential overlap should not deflect this court from determining the different question as to whether the continued detention can no longer be justified by the original decision that the prisoner was dangerous."
