“I have concluded that article 5(4) requires no more than that “a court” (the Parole Board) shall speedily decide whether the prisoner continues to be lawfully detained and this will indeed be the case until the Board is satisfied of his safety for release. … I accept that article 5(4) requires a basic rule 6 dossier to be made available; without this the Board simply cannot function. But I cannot accept that article 5(4) requires anything more in the way of enabling the Board to form its judgment. … [61] … As Mr Saini submits, [article 5(4)] is concerned with procedure not substance … Clearly the Board is able to examine the substantive question of the prisoner’s dangerousness. The fact that on the material before the Board the prisoner may be unable to demonstrate his safety for release no more involves a breach of article 5(4) than that those detained in Northern Ireland may have been unable on a habeas corpus challenge to refute the reasonableness of the suspicion grounding their arrest.”
“Article 5(4) requires that a system must be in place for making that assessment at reasonable intervals which meets the requirements of procedural fairness. How that system works in practice in any given case is a matter for the Parole Board itself to determine. It is open to it to decide how much information it needs, to conclude that for whatever reason the information that is available for the time being is inadequate and to set its own timetable for the information that it needs to be made available. It is entitled to expect cooperation from those responsible for the management of the sentence in meeting its requirements. But a failure to meet them does not of itself mean that there will be a breach of article 5(4). As in the case of Article 5(1)(a), it will only be if the system which the statutes have laid down breaks down entirely because the Parole Board is denied the information that it needs for such a long period that continued detention has become arbitrary that the guarantee that article 5(4) provides will be violated and the prisoner will be entitled to a remedy in damages”
