“a significant… risk to members of the public of serious harm; that is of death or serious personal injury, whether physical or psychological, caused by the commission by you of further “specified offences”.”
"Everyone has the right to liberty and security of person. No one shall be deprived of his liberty save in the following cases and in accordance with a procedure prescribed by law: (a) the lawful detention of a person after conviction by a competent court…"
“In Bradley the court was concerned with the extent of the risk relevant to sentencing and to release on licence. In rejecting Mr Edward Fitzgerald's submission that the two must equate, the court said (paragraphs 145F-H): "the sentencing court recognises that passing a life sentence may well cause the accused to serve longer, and sometimes substantially longer, than his just deserts. It must thus not expose him to that peril unless there is compelling justification for such a course. That compelling justification is the perception of grave future risk amounting to an actual likelihood of dangerousness. But of course the court's perception of that future risk is inevitably imprecise. It is having to project its assessment many years forward and without the benefit of a constant process of monitoring and reporting such as will be enjoyed by the Parole Board. When at the post-tariff stage the assessment comes to be made by that Board they are thus much better placed to evaluate the true extent of the risk which will be posed by the prisoner's release. And they are a more expert body, custom built by Parliament for the purpose. Given those considerations, and given too that their recommendation for release on licence, if accepted by the Secretary of State, will have immediate effect in terms of endangering public safety – quite unlike the decision of the Trial Judge whose sentence would in any event have protected society for an appreciable time – it seems to us perfectly appropriate for the Parole Board to apply some lower test of dangerousness, i.e. one less favourable to the prisoner”. “The court went on to say of the level of risk relevant at the release stage, that it "must indeed be 'substantial' …, but this can mean no more than that it is not merely perceptible or minimal", that it must be unacceptable in the subjective judgment of the Parole Board and that the Parole Board must have in mind all material considerations, scrutinising ever more anxiously whether the level of risk is unacceptable, the longer the time the offender has spent in prison post-tariff (paragraph 146D-F, and see R v ParoleBoard, Ex p Wilson[1992] QB 740 , 747E-G).”
“Whether the claimant is in an analogous situation to others convicted after3 December 2012 must be judged in the context of his complaint that he is subject to an indeterminate period of imprisonment and cannot be released without satisfying the Parole Board that he is no longer a danger to the public. He maintains he is not challenging his original sentence. But however he cloaks his application, the real complaint he advances is a challenge to his original sentence, the essence of which is that he will not be released until it is safe to do so. The reality of his argument is that he was sentenced under a different regime. It is not coherent then to allege discrimination when compared to other offenders sentenced under a different regime. They are not in an analogous situation precisely because they were sentenced under a different regime. The claimant cannot complain because Parliament has now abolished IPPs and introduced a different type of sentence. The United Kingdom is not obliged, under the Convention, to re-open historical sentences and re-sentence merely because it has introduced a new sentencing regime. I would dismiss this application on both the two grounds before the court.”
“(1) No one shall be held guilty of any criminal offence on account of any act or omission which did not constitute a criminal offence under national or international law at the time when it was committed. Nor shall a heavier penalty be imposed than the one that was applicable at the time the criminal offence was committed.”
“the prisoner’s continued liberty or, as the case may be, immediate release, would present an unacceptable risk to the public of further offences being committed.”
