2. References to the “Procedure” are references to an expert determination conducted in accordance with the Rules in Parts I and II.

3. “Agreement” means an agreement between two or more parties allowing for expert determination of a dispute or issue.

4. The “Expert” is defined in Part I, Rule 4.

5. The “Rules” and “The Academy’s Rules” shall mean the applicable rules in Parts I and II.

6. Words used in the singular include the plural and vice versa as the context may require. The masculine is taken to include any person or entity.

Rule 2: Scope

Where an Agreement provides for expert determination under The Academy’s Rules, the Rules in force at the time the agreement is entered into shall be deemed to form part of that agreement.

Rule 3: Services of Notices, Communication and time calculation

1. Unless the parties have agreed otherwise, any notice or other communication that may be or is required to be given under these Rules shall be:

(a) in writing and delivered by post, delivery service or email and

(b) copied to each of the other parties and the Expert.

2. For the purpose of calculating a period of time under these Rules: in the case of delivery by post, it shall begin to run from 48 hours after 9am on the date after it is evidenced the notice or communication was sent; in the case of delivery by a delivery service, it shall begin to run on such date as the service provider records the fact of delivery; in the case of an email sent before 4pm, it shall begin to run from the time of sending; in the case of an email sent after 4pm, it shall begin to run from the following day. In each case, unless otherwise expressly agreed between the relevant parties, the time zone from which the communication is sent shall apply.

3. Any reference to “days” in this agreement means whole calendar days and excludes weekends and public holidays.

Rule 4: Appointment of the Expert

The parties shall agree to the appointment of an expert (the “Expert”) and his terms of engagement. If the parties are unable to agree on an Expert, The Academy will nominate up to 3 experts and the parties shall then endeavour to choose and appoint the Expert from the nominations within 14 days. If the parties are unable to agree on the identity of an Expert after the said 14 days, The Academy shall nominate the Expert. A party may object to The Academy’s first nomination by sending the reasons for his objection to The Academy in writing within 7 days of receipt of the notice of nomination. The Academy shall consider the reasons for the objection and may in its absolute discretion nominate another Expert. The parties shall accept as final the second nomination of The Academy or The Academy’s decision not to nominate a further Expert. Upon completion of this procedure, the parties shall appoint the applicable Expert.

Rule 5: The Expert

1. Function: the Expert shall act as an expert and shall determine the dispute before him. The Expert shall not act as an arbitrator or adjudicator, nor as an expert witness. The parties agree that the expert determination process is not an arbitration or adjudication within the meaning of any statute.

2. Role: the Expert shall adopt procedures suitable to the circumstances of the particular case so as to provide an expeditious, cost-effective and fair means of determining the dispute between the parties.

3. Neutrality: the Expert shall act with impartiality, shall have no vested interest in the outcome of the dispute or issue and shall not be biased in any way towards or against any party. If the Expert becomes aware of any circumstance which might reasonably be considered to affect his ability to act impartially, he shall inform the parties and The Academy immediately. The parties shall then inform the Expert and The Academy within 10 days whether or not they agree that the Expert should continue the determination. If the Expert wishes to continue and any party considers that the Expert should withdraw, The Academy will decide whether the Expert is to withdraw. The Academy’s decision will be binding. A new expert will be appointed under Rule 4 of Part I.

4. Evidence: the Expert is not bound by the rules of evidence and may at his discretion receive and take into consideration any information submitted to him by any party in such manner as he thinks fit and may give such weight to the same as he considers appropriate.

5. Final and binding: the Expert’s determination shall be final and binding on the parties. It shall be made in writing, signed and dated and communicated to all parties.

6. Interest: the Expert has discretion to determine that simple interest is payable at such a rate and for such period as he thinks fit on any amount in dispute or any part of it. The Expert may also decide that interest for late payment following determination is payable at such a rate as he thinks fit.

7. Payment: unless otherwise expressly agreed in writing by the parties any amount payable under the determination shall be paid within fourteen days of the determination.

8. Liability: the Expert shall not be liable for any act or omission arising from the Expert determination under these Rules unless such act or omission is shown to have been fraudulent or as a result of collusion. The Academy and any officer, or employee or agent or authorised representative of The Academy shall not be liable for any such act or omission of the Expert unless it is shown that he was a party to fraudulent or collusive conduct by the Expert.

9. Status of Expert’s deliberations and materials: the Expert shall not voluntarily divulge, produce or disseminate or provide details (in whole or in part) of any evidence, documents or information arising from the Procedure to any person or body other than the parties. The Expert will only be released from the requirements of this sub-Rule where he is under a legal obligation to provide evidence or other information.

10. Incapacity, inactivity, resignation or death:

(a) if due to sickness, other incapacity or a conflict of interest arising after his appointment, the Expert is unable to reach a determination in accordance with a timetable acceptable to the parties or as otherwise set out in Rule 8 of Part II, the Expert shall withdraw from the Procedure.

(i) retain any interim payments that have been made in the course of, and be entitled to receive any payments duly invoiced, in relation to the Procedure and shall forego the rest of his fee; and

(ii) arrange for the documents to be returned to the parties.

(b) If the Expert is unwilling to reach a determination within the agreed timescale or at all, he shall withdraw from the Procedure. In such circumstances, he shall:

(i) forego his fee and repay any interim payments already made in the course of the Procedure; and

(ii) arrange for the documents to be returned to the parties.

(c) If the Expert dies during the course of the determination, The Academy will use its reasonable endeavours to arrange for the parties’ documents to be returned.

In any of the circumstances described in (a), (b) and (c) of this Rule, the Academy will, if the parties so wish, nominate another Expert whom the parties shall then appoint.

11. Discretion: at the request in writing of either party, and either with the agreement of all other parties or of his own motion, the Expert shall have discretion:

(a) to amend the time limits set out in Parts I and II of these Rules and/or

(b) to amend any of the Procedural Rules in Part II of these Rules.

The Expert’s decision as to his exercise of this discretion shall be final.

12. Consultation: unless otherwise determined by the Expert and agreed with the parties, no one party or anyone acting on one party’s behalf shall communicate with the Expert in the absence of the other party.
