5.1 Reference to Arbitration
If:
(a) there is any dispute in respect of matters referred to in clause 44 (Change in Law), Schedule 24 (Compensation on Termination) or the Change Protocol; or
(b) either party is dissatisfied with or otherwise wishes to challenge the Adjudicator's decision made in accordance with paragraph 4.4; or
(c) both parties agree,
then either party may (within twenty-eight (28) days of receipt of the Adjudicator's decision, where appropriate), notify the other party of its intention to refer the dispute to arbitration. Such notification shall invite the other party to concur in the appointment of a sole arbitrator who shall be a solicitor, barrister or arbitrator recognised by the Chartered Institute of Arbitrators of not less than ten (10) years' standing (the Arbitrator). If the parties are unable within fourteen (14) days to agree the identity of the Arbitrator either party may request the President of the Law Society to make the appointment.
