" It seems to me generally desirable that the Board should identify in broad terms the matters judged by the Board as pointing towards and against a continuing risk of offending and the Board's reasons for striking the balance that it does. Needless to say, the letter should summarise the considerations which have in fact led to the final decision. It would be wrong to prescribe any standard form of Decision Letter and it would be wrong to require elaborate or impeccable standards of draftsmanship. "
"( vi) In some circumstances, however, the Board may not be able to make findings of fact as to the truth of an allegation either because of an inability to obtain sufficiently reliable evidence or because it would be unfair to expect the prisoner to give an answer to the allegation when he is facing criminal or prison disciplinary proceedings in relation to that allegation. "(vii) In such circumstances the Board, having regard to public safety, may take into account the allegation or allegations and give it or them such weight as it considers appropriate in a holistic assessment of all the information before it, where it is concerned that there is a serious possibility that those allegations may be true. But the Board must proceed with considerable caution in this exercise because of the consequences of its decision on the prisoner. Procedural fairness requires the Board to give the prisoner the opportunity to make submissions about how the Board ought to proceed. There may be circumstances where, because of the inadequacy of the information available to the Board, it concludes that it should not take account of an allegation at all. There may also be circumstances where the information is less than would be desired, but the allegation causes sufficient concern as to risk that the Board treats it as relevant. Its assessment of the weight to be attached to an allegation is subject to the constraints of public law rationality."
