6.       Material not called by Defence counsel

[…]

65.     As indicated above, when evidence was not called because of the advice of defence counsel in charge at the time, it cannot be right for the Appeals Chamber to admit additional evidence in such a case, even if it were to disagree with the advice given by counsel. The unity of identity between client and counsel is indispensable to the workings of the International Tribunal. If counsel acted despite the wishes of the Appellant, in the absence of protest at the time, and barring special circumstances which do not appear, the latter must be taken to have acquiesced, even if he did so reluctantly[1]. An exception applies where there is some lurking doubt that injustice may have been caused to the accused by gross professional incompetence. Such a case has not been made out by the Appellant. Consequently, it cannot be said that the witnesses and material were not available to the Appellant despite the exercise of due diligence.
