21 It will suffice only briefly to set out the legal principles which apply to the construction of a commercial document such as the contract.
22 In construing a commercial contract the Court has regard to the language used, the surrounding circumstances known to the parties, the purpose of the transaction and the objects which it was intended to secure: Toll (FGCT) Pty Ltd v Alphapharm Pty Ltd (2004) 219 CLR 165 at 179; International Air Transport Association v Ansett Australia Holdings Ltd (Subject to Deed of Company Arrangement) (2008) 212 ALR 47 at [8].
23 The whole of the instrument has to be considered. Preference is given to a construction supplying a congruent operation to the various components of the whole of an instrument: Wilkie v Gordian Runoff Limited (2005) 221 CLR 522 at 529.
24 If the words used are unambiguous, the Court must give effect to them. If the language is open to two constructions, that will be preferred which will avoid consequences which appear to be capricious, unreasonable, inconvenient or unjust: Australian Broadcasting Commission v Australasian Performing Right Association Limited (1973) 129 CLR 99 at 109.
25 In relation to alternative dispute resolution clauses in particular, in Francis Travel Marketing Pty Ltd v Virgin Atlantic Airways Ltd (1996) 39 NSWLR 160 at 165, Gleeson CJ said:
When the parties to a commercial contract agree, at the time of making the contract, and before any disputes have yet arisen, to refer to arbitration any dispute or difference arising out of the agreement, their agreement should not be construed narrowly. They are unlikely to have intended that different disputes should be resolved before different tribunals, or that the appropriate tribunal should be determined by fine shades of difference in the legal character of individual issues, or by the ingenuity of lawyers in developing points of argument.
26 More recently in Fiona Trust & Holding Corporation v Privalov [2008] 1 Lloyd's Rep 254 at 256 Lord Hoffmann said:
In approaching the question of construction, it is therefore necessary to inquire into the purpose of the arbitration clause. As to this, I think there can be no doubt. The parties have entered into a relationship, an agreement or what is alleged to be an agreement or what appears on its face to be an agreement, which may give rise to disputes. They want those disputes decided by a tribunal which they have chosen, commonly on the grounds of such matters as its neutrality, expertise and privacy, the availability of legal services at the seat of the arbitration and the unobtrusive efficiency of its supervisory law. Particularly in the case of international contracts, they want a quick and efficient adjudication and do not want to take the risks of delay and, in too many cases, partiality, in proceedings before a national jurisdiction.
27 For the following reasons, I consider that the plaintiff's construction is untenable.
28 Firstly and somewhat fundamentally, the plain and unambiguous words of cl 42.10(c) require the expert determination to be given effect to unless and until it is reversed, overturned, or otherwise changed under the procedure in cl 42.11.
29 That procedure has done whatever work it could do in the present circumstances and the expert determination has not been reversed, overturned or otherwise changed. It follows that it remains binding. It is not suggested that the parties did not comply with whatever obligations they had under cl 42.11, nor is it suggested that that procedure has not been exhausted. It may also be observed that cl 42.11 refers to the persons described in Annexure Part A. That annexure contained no such description. Both parties accepted, however, that the clause was given effect to by the negotiations between the parties and no party put that cl 42.11 was void for uncertainty.
