33 At this stage, I put to one side the question of the extent to which without prejudice privilege may or may not prevent the Court investigating the extent to which the Dispute Resolution Committee review process and the Chief Executive Officer review process provided for in clauses 73.2 and 73.3 of the Subcontract, respectively, have been complied with. I am of the view that the provisions of clause 73.1, particularly paragraph (e), would prevent either party commencing proceedings, other than as provided for in that paragraph, prior to compliance with clauses 73.2 and 73.3, even assuming the plaintiff's submissions with respect to the question of election on the basis of its interpretation of the concluding words of clause 73.3 were correct. In any event, I am of the view that, in the event that the parties fail to agree, following the Chief Executive Officer review under clause 73.3, that the dispute is to be referred to an Expert for determination under clause 73.4, or to arbitration pursuant to clause 73.5. As indicated previously, this accords with the comprehensive scheme provided for in clause 73 and, in particular, gives effect to paragraphs 73.1(b), (c) and (e).[21] Consequently, I am of the opinion that no issue of election arises. Properly construed, the provisions of clause 73.3 and the related provisions of clause 73 provide an agreement that a matter be referred to arbitration for the purposes of s 53(1) of the Act.
