The victim had been stabbed outside a nightclub. Two witnesses identified the defendant. The defendants complained that evidence had not been disclosed to them.
Held: There is no duty at common law on the prosecution to warn the defence of material which might be used to attack the credibility of defence witnesses. Fairness, so far as the preparation of the defence case and the selection of the defence witnesses are concerned, is preserved by the existing rules of disclosure and by ensuring that the defendant has adequate time and facilities for the preparation of his defence. ‘The preparation of the defence case is not complete until this has been done. Once it has been completed, the defence can be assumed to be in possession of all that is needed to decide which witnesses to lead and which to reject on grounds of credibility. It is unnecessary to extend the duty of disclosure by the prosecutor any further to ensure that the defendant has a fair trial.’ but ‘If fairness demands disclosure, then a way of ensuring that disclosure will be made must be found.’ (Lord Hope of Craighead )
