Part VIII — CONDUCT OF THE ARBITRATION
28.1 The Tribunal shall determine the admissibility, relevance, materiality, and weight of evidence.

28.3 Witness evidence shall, unless the Tribunal otherwise directs, be given first by written statement. The witness shall attend examination unless excused by the Tribunal.
28.4 Expert evidence shall be identified at the earliest case management conference and confined to genuinely contested technical or specialised issues. Joint expert reports and expert conferencing (hot-tubbing) shall be preferred.
