" … by being in denial they [i.e., prisoners] limit – and in many cases severely limit – the practical opportunity of demonstrating that the risk has diminished. Indeed, their denial demonstrates that they have not accepted that the risk was ever present." 28. Fourthly, the common law duty of procedural fairness will sometimes require CART to convene an oral hearing when considering whether or not to downgrade a Category A prisoner. As Bean J rightly observed (at [27] of the Judgment), it is for the court to decide what fairness requires, so that the issue on judicial review is whether the refusal of an oral hearing was wrong; not whether it was unreasonable or irrational. Whether an oral hearing is required in an individual case will be fact specific. Given the rationale of procedural fairness, there is no requirement that exceptional circumstances should be demonstrated – there will be occasions when procedural fairness will require an oral hearing regardless of the absence of exceptional circumstances. But oral hearings are plainly not required in all cases; indeed, oral hearings will be few and far between. Advantages may be improved decision-making, bringing CART into contact with those who have direct dealings with the offender and the offender himself; an oral hearing may also assist in the resolution of disputed issues. Conversely, considerations of cost and efficiency may well tell against an oral hearing. There can be no single or even general rule, save, perhaps, for the recognition that oral hearings will be rare. By way of brief amplification: i) As to the common law duty of procedural fairness and the holding of an oral hearing, Lord Bingham of Cornhill said this in the distinct if not altogether unrelated context of the recall to prison of a prisoner on licence: "35. The common law duty of procedural fairness does not….. require the board to hold an oral hearing in every case where a determinate sentence prisoner resists recall, if he does not decline the offer of such a hearing. But I do not think the duty is as constricted as has hitherto been held and assumed. Even if important facts are not in dispute, they may be open to explanation or mitigation, or may lose some of their significance in the light of other new facts. While the board's task certainly is to assess risk, it may well be greatly assisted in discharging it (one way or the other) by exposure to the prisoner or the questioning of those who have dealt with him. It may often be very difficult to address effective representations without knowing the points which are troubling the decision-maker. The prisoner should have the benefit of a procedure which fairly reflects, on the facts of his particular case, the importance of what is at stake for him, as for society."
"Lord Bingham's statement of principle makes clear that common law standards of procedural fairness affecting an oral hearing are flexible, may change over time, and in general terms depend on the circumstances of the case. Clearly oral hearings are not required in all or even most cases, but importantly the context in which procedural fairness is being considered is determinative. There is no test of exceptionality. One considers the interests at stake and also the extent to which an oral hearing will guarantee better decision-making in terms of uncovering of facts, the resolution of issues, and the concerns of the decision-maker. Cost and efficiency must also be considered, often on the other side of the balance."
