13.     Rule 93 provides that “Evidence of a consistent pattern of conduct relevant to serious violations of international humanitarian law under the Statute may be admissible in the interests of justice.” Rule 93 does not create an exception to Rule 89(C), but rather is illustrative of a specific type of evidence which may be admitted by a Trial Chamber. Rule 93 must be read in conjunction with Rule 89(C), which permits a Trial Chamber to admit any relevant evidence which it deems to have probative value. Even where pattern evidence is relevant and deemed probative, the Trial Chamber may still decide to exclude the evidence in the interests of justice when its admission could lead to unfairness in the trial proceedings, such as when the probative value of the proposed evidence is outweighed by its prejudicial effect, pursuant to the Chamber’s duty to ensure a fair and expeditious trial as required by Article 19(1) of the Statute of the International Tribunal.
