"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 the procedure prescribed by law. "(a) the lawful detention of a person after conviction by a competent court."
"Everyone who is deprived of his liberty by arrest or detention shall be entitled to take proceedings by which the lawfulness of his detention shall be decided speedily by a court and his release ordered if the detention is not lawful."
"By contrast, the justification that is required for his detention after the tariff's expiry as the preventative element begins and continues is of an altogether different character. This further detention is not at all justified by or at the time of sentence for the very reason that the extent to which or the time for which the prisoner will remain a danger is unknown at the time of sentence. It can only be ascertained on a continuing basis by periodic assessment. Nothing else can justify this further detention."
"Reducing the risk opposed by lifers must be inherent in the legislation's purpose, since otherwise the statutes would be indifferent to the imperative that treats imprisonment strictly and always as a last resort. Whether or not the prisoner ceases to present a danger cannot be a neutral consideration in statute or policy. If it were, we would forgo any claim to a rational and humane and efficient prison regime, thus the existence of measures to allow and encourage the IPP prisoner to progress is as inherent in the justification for his continued detention as are the Parole Board reviews themselves, and without them, that detention falls to be condemned as unlawful as surely as if there were no such reviews."
"When sentence is passed it is not to be presumed against the prisoner that he will still be dangerous after his tariff expires, let alone months or years later. He may or may not be. Whether he is or not, and therefore whether his continuing incarceration is justified or not, can only be determined by reference to up-to-date (at the very least reasonably up-to-date) information enabling the decision-maker, the Parole Board, to form a view of the question of risk in his case."
