9. Because the question whether to grant leave to amend the indictment is committed to the discretion of the Trial Chamber by Rule 50 of the Rules, appellate intervention is warranted only in limited circumstances.  As the Appeals Chamber of the International Criminal Tribunal for the former Yugoslavia (“ICTY”) has explained, the party challenging the exercise of a discretion must show “that the Trial Chamber misdirected itself either as to the principle to be applied, or as to the law which is relevant to the exercise of the discretion, or that it has given weight to extraneous or irrelevant considerations, or that it has failed to give weight or sufficient weight to relevant considerations, or that it has made an error as to the facts upon which it has exercised its discretion.”  If the Trial Chamber has properly exercised its discretion, the Appeals Chamber may not intervene solely because it may have exercised the discretion differently.  However, if the Trial Chamber has committed an error that has prejudiced the party challenging the decision, the Appeals Chamber “will review the order made and, if appropriate and without fetter, substitute its own exercise of discretion for that of the Trial Chamber.”

12.  […] The Prosecution is entitled to decide that its theory of the accused’s criminal liability would be better expressed by an amended indictment.  Even if the trial can proceed on the basis of the Current Indictment, the Prosecution is not thereby precluded from seeking to amend it.

20. […] [A]lthough Rule 50 does not require the Prosecution to amend the indictment as soon as it discovers evidence supporting the amendment, neither may it delay giving notice of the changes to the Defence without any reason.  The Prosecution cannot earn a strategic advantage by holding an amendment in abeyance while the defence spends time and resources investigating allegations that the Prosecution does not intend to present at trial.  In this regard, it is worth recalling that a substantial delay will be considered undue “if it occur[s] because of any improper tactical advantage sought by the prosecution.”   Strategic efforts to undermine the conduct of proceedings cannot be tolerated, especially if designed to disadvantage the ability of the Defence to respond to the Prosecution’s case.  

18. […][T]he Appeals Chamber agrees that judicial economy may be a basis for rejecting a motion that is frivolous, wasteful, or that will cause duplication of proceedings.

19.     The Trial Chamber correctly considered that the Registrar has the primary responsibility in the determination of matters relating to remuneration of counsel under the Legal Aid System of the International Tribunal. The Appeals Chamber has already held that, where the Directive expressly provides for a review of the Registrar’s decision, the Trial Chamber cannot interfere in the Registrar’s decision, and its only option is to stay the trial until that procedure has been completed.[1] Where, however, the Directive does not expressly provide for a review of the Registrar’s decision, the Trial Chamber, pursuant to its statutory obligation to ensure the fairness of the trial, is competent to review the Registrar’s decision in the light of its effect upon the fairness of the trial.

20.     The exercise of such power should, however, be closely related to the fairness of the trial, and it should not be used as a substitute for a general power of review which has not been expressly provided in the Directive. […]

11.       The ICTY is entrusted with bringing justice to the former Yugoslavia.  First and foremost, this means justice for the victims, their relatives and other innocent people.  Justice, however, also means respect for the alleged perpetrators’ fundamental rights. Therefore, no distinction can be drawn between persons facing criminal procedures in their home country or on an international level.

12.      Rules 65 (B) and (D) of the Rules must therefore be read in the light of the ICCPR and ECHR and the relevant jurisprudence.

13.     Moreover, when interpreting Rule 65(B) and (D) of the Rules, the general principle of proportionality must be taken into account. A measure in public international law is proportional only when it is (1) suitable, (2) necessary and when (3) its degree and scope remain in a reasonable relationship to the envisaged target. Procedural measures should never be capricious or excessive. If it is sufficient to use a more lenient measure than mandatory detention, it must be applied.[1]    

25.     According to the settled practice of the International Tribunal, it is the State into the territory of which the accused will be released, as the guarantor of public safety and order in that territory, that must provide the International Tribunal with guarantees that the accused will not flee and that if he does so, he will be arrested. […]  

9. The Appeals Chamber will address two preliminary arguments. First, the Appellants contend that the two remaining judges in the Butare trial sat in the plenary which amended Rule 15bis on 27 May 2003 and that this impaired their impartiality.  The argument overlooks the fact that judges can in a legislative capacity make rules without prejudice to their right to pronounce in a judicial capacity on the vires or operation of the rules so made. In this case, article 14 of the Statute, which gives a rule-making competence to the judges of the Tribunal, does not prevent them from later deciding in their judicial capacity on the vires or operation of the rules adopted.

25. There is a preference for live testimony to be heard by each and every judge. But that does not represent an unbending requirement. The Rules and the cases show that exceptions can be made. The exceptions may relate even to evidence involving an assessment of demeanour, various ways being available to assist a new judge to overcome any disadvantages. The Appellants have not attacked the procedure prescribed by Rule 15(A) or Rule 15(B). Under these provisions, a witness could be heard by two judges; that the procedure is, in effect, available only over a short period of time is not relevant to the principle involved. Nor have the Appellants attacked the procedure prescribed by the old Rule 15(C) by virtue of which, in a part-heard case, a substitute judge could come in for the remainder of the trial; that this was possible only with the consent of the accused (where opening statements had been made or evidence had begun to be presented) was, again, not relevant to the principle involved. And then there is the case of deposition evidence admitted under Rule 71. In all these cases, the temporarily absent judge or the substitute judge, as the case may be, is faced with the task of evaluating evidence not given before him.

[…]

34.     The recomposed Trial Chamber may recall witnesses so as to enable the substitute judge to assess their demeanour on particular points. The recall decision would be made by the recomposed Trial Chamber after the proposed judge has joined it. Where video-recordings are available, an absent judge who reviews such recordings does so as a member of the bench, as in all the cases mentioned in paragraph 25 above. In like manner, in this case the substitute judge would be hearing recalled testimony as a member of the recomposed Trial Chamber. The recall power lies within the normal competence of the recomposed Trial Chamber. It was not for the two judges to authorize it to exercise that competence, although they could note that competence.

23. The discretion of the Trial Chamber meant that the Trial Chamber had the right to establish the precise point within a margin of appreciation at which a continuation should be ordered. In that decision-making process, the Appeals Chamber can intervene only in limited circumstances, as, for example, where it is of the view that there was a failure to exercise the discretion, or that the Trial Chamber failed to take into account a material consideration or took into account an immaterial one and that the substance of its decision has in consequence been affected. It is not enough that the Appeals Chamber would have exercised the discretion differently. However, even if a trial court has not otherwise erred, the appellate “court must, if necessary, examine anew the relevant facts and circumstances to exercise a discretion by way of review if it thinks that the judge’s ruling may have resulted in injustice to the appellants.”[1]

[…]

27. The Appeals Chamber does not consider it useful to lay down a hard and fast relationship between the proportion of witnesses who have already testified and the exercise of the power to order a continuation of the trial with a substitute judge. The discretion to continue the trial with a substitute judge is a discretion; the Appeals Chamber can only interfere with the way in which the discretion has been exercised if it has been incorrectly exercised in the circumstances mentioned above.  The stage reached in each case need not always be the same.
