Procedure

4

• (1) The parties’ pleadings, witness statements and expert reports (if any) will be concise. No single pleading will exceed 30 single sided A4 pages using 10pt Arial font.

• (2) The arbitrator will make an award on the substantive difference(s) based solely on the written material submitted by the parties unless the arbitrator decides that a hearing is necessary to explain or resolve any matters.

• (3) Either party may, within 2 days of delivery of the last submission, request a hearing giving specific reasons why it considers a hearing is required.

• (4) Within 7 days of receiving the last submission, the arbitrator will notify the parties whether a hearing is to be held and the length of that hearing.

• (5) Within 10 days of the arbitrator advising the parties that they will hold a hearing, the date and venue for the hearing will be fixed by agreement with the parties, save that if there is no agreement the arbitrator is to direct a date and venue which they consider is fair and reasonable in all the circumstances. The date for the hearing must not be less than 35 days from the date of the arbitrator’s direction confirming the date and venue of the hearing.

• (6) A decision will be made by the arbitrator on whether there is any need for expert evidence to be submitted orally at the hearing. If oral expert evidence is required by the arbitrator, then any expert(s) attending the hearing may be asked questions by the arbitrator.

• (7) There will be no process of examination and cross-examination of experts, but the arbitrator must invite the parties to ask questions of the experts by way of clarification of any answers given by the expert(s) in response to the arbitrator’s questions. Prior to the hearing the procedure for the expert(s) will be that—

• (a) at least 28 days before a hearing, the arbitrator will provide a list of issues to be addressed by the expert(s);

• (b) if more than one expert is called, they will jointly confer and produce a joint report or reports within 14 days of the issues being provided; and

• (c) the form and content of a joint report must be as directed by the arbitrator and must be provided at least 7 days before the hearing.

• (8) Within 14 days of a hearing or a decision by the arbitrator that no hearing is to be held, the parties may by way of exchange provide the arbitrator with a final submission in connection with the matters in dispute and any submissions on costs. The arbitrator must take these submissions into account in the award.

• (9) The arbitrator may make other directions or rulings as considered appropriate in order to ensure that the parties comply with the timetable and procedures to achieve an award on the substantive difference within 4 months of the date on which they are appointed, unless both parties otherwise agree to an extension to the date for the award.

• (10) If a party fails to comply with the timetable, procedure or any other direction then the arbitrator may continue in the absence of a party or submission or document, and may make a decision on the information before him/her attaching the appropriate weight to any evidence submitted beyond any timetable or in breach of any procedure and/or direction.

• (11) The arbitrator’s award must include reasons. The parties must accept that the extent to which reasons are given must be proportionate to the issues in dispute and the time available to the arbitrator to deliver the award.

Arbitrator’s powers

5

• (1) The arbitrator has all the powers of the Arbitration Act 1996⁴¹, including the non-mandatory sections, save where modified by these Rules in this Schedule.

• (2) There must be no discovery or disclosure, except that the arbitrator is to have the power to order the parties to produce such documents as are reasonably requested by another party no later than the Statement of Reply, or by the arbitrator, where the documents are manifestly relevant, specifically identified and the burden of production is not excessive. Any application and orders should be made by way of a Redfern Schedule without any hearing.

• (3) Any time limits fixed in accordance with this procedure or by the arbitrator may be varied by agreement between the parties, subject to any such variation being acceptable to and approved by the arbitrator. In the absence of agreement, the arbitrator may vary the timescales and/or procedure—

• (a) if the arbitrator is satisfied that a variation of any fixed time limit is reasonably necessary to avoid a breach of the rules of natural justice and then;

• (b) only for such a period that is necessary to achieve fairness between the parties.

• (4) On the date the award is made, the arbitrator will notify the parties that the award is completed, signed and dated, and that it will be issued to the parties on receipt of cleared funds for the arbitrator’s fees and expenses.

Costs

6

• (1) The costs of the arbitration must include the fees and expenses of the arbitrator, the reasonable fees and expenses of any experts and the reasonable legal and other costs incurred by the parties for the arbitration.

• (2) Where the difference involves connected/interrelated issues, the arbitrator will consider the relevant costs collectively.

• (3) The final award must fix the costs of the arbitration and decide which of the parties are to bear them or in what proportion they are to be borne by the parties.

• (4) The arbitrator will award recoverable costs on the general principle in paragraph (3) that each party should bear its own costs, having regard to all material circumstances, including such matters as exaggerated claims and/or defences, the degree of success for different elements of the claims, claims that have incurred substantial costs, the conduct of the parties and the degree of success of a party.

Confidentiality

7

• (1) Subject to sub-paragraphs (2) and (3), any arbitration hearing and documentation is to be open to and accessible by the public.

• (2) The arbitrator may direct that the whole or part of a hearing is to be private or any documentation to be confidential where it is necessary in order to protect commercially sensitive information.

• (3) Nothing in this paragraph prevents any disclosure of a document by a party pursuant to an order of a court in England and Wales or where disclosure is required under any enactment.
