10.5 The Arbitrator may, if he consider is necessary or expedient for the just disposal of the Arbitration or for the saving of costs or otherwise, order that a witness may give oral evidence by videolink or by telephone or may give written evidence on-line and be cross examined thereon.

10.6 The testimony of witnesses may be presented in written form, either as signed statements or by duly sworn affidavits, and the Arbitrator may order that such statements or affidavits shall stand as evidence-in-chief. Subject to Article 10.3 any party may request that such a witness should attend for oral examination at a hearing. If the witness fails to attend, the Arbitrator may place such weight on the written testimony as he thinks fit, or may exclude it altogether.
