Determination
19For the reasons which follow, it is my opinion that s 7C of the Home Building Act renders void only that part of clause 45.1 which provides that either party may require a dispute under the contract to be referred to arbitration. That part, which consists of the words "but the Principal or the Contractor may give notice requiring the dispute or difference to be referred to arbitration in accordance with the provisions of subclause 45.4", in my opinion constitutes "a provision [...] that requires a dispute under the contract to be referred to arbitration" within the meaning of s 7C of the Home Building Act.
20Section 7C is, in its terms, evidently directed only at provisions that require contractual disputes to be referred to arbitration. The section calls for the identification of a provision that bears that particular character. It is not directed at provisions that concern other forms of dispute resolution, such as mediation or expert determination.
21In keeping with that intention, "provision" within s 7C should not be given a meaning of such breadth that it would have the effect of bringing down provisions which do not themselves require contractual disputes to be referred to arbitration. Rather, "provision" within s 7C should be construed so that it is limited to identifiable parts of a contract that themselves bear the prohibited character.
22In this case, the concluding words of clause 45.1 can be identified as a part of the contract that bears that character. It is a provision that requires, in certain circumstances, a dispute under the contract to be referred to arbitration. It does not matter, in my view, that such requirement only arises if the expert's decision falls within a particular description and one of the parties then elects to give a notice (see PMT Partners Pty Limited (in liquidation) v Australian National Parks and Wildlife Service [1995] HCA 36; (1995) 184 CLR 301 at 310 and 323). Accordingly, applying the construction I prefer, those words constitute a provision that falls within s 7C, and such provision is void.
23I do not think that the reasoning of Barrett J in Savcor Pty Ltd v State of New South Wales and Another (supra) calls for a different conclusion. In that case, his Honour was dealing with a different question arising under a different statute, namely, whether the plaintiff was a party to an arbitration agreement within the meaning of the Commercial Arbitration Act 1984 (NSW). For that purpose, Barrett J dealt with admittedly similar dispute resolution provisions as found in clause 46 of the contract before him. An "arbitration agreement" was defined, for the purposes of the Commercial Arbitration Act, as "an agreement in writing to refer present or future disputes to arbitration". Barrett J held, applying the observations made by the High Court in PMT Partners Pty Limited (in liquidation) v Australian National Parks and Wildlife Service (supra) at 310 and 323, that clause 46, or at least part of clause 46, was an arbitration agreement as defined (see at [21], [23]-[25] and [27]-[28]). It was not critical for his Honour to decide whether the whole of clause 46, or only a part or parts of it, was an arbitration agreement. It was sufficient to find that the clause encompassed an agreement in writing to refer to present or future disputes to arbitration, hence the plaintiff was a party to an arbitration agreement.
24Further, I do not think that holding the concluding words of clause 45.1 to be void by reason of s 7C leads to the conclusion that the balance of clause 45.1 should also be treated as of no effect. In my view, those provisions are severable from the void provision. Only a relevantly minor alteration to the contract is brought about by the intervention of the statute.
25I was referred by counsel to the discussion by Allsop P of the principles of severance (in the context of a contractual provision void for uncertainty) in United Group Rail Services Ltd v Rail Corporation New South Wales [2009] NSWCA 177; (2009) 74 NSWLR 618 at [90]-[97], as well as the statement of Jordan CJ in McFarlane v Daniell (1938) 38 SR (NSW) 337 at 345 where his Honour said:
"When valid promises supported by legal consideration are associated with, but separate in form from, invalid promises, the test of whether they are severable is whether they are in substance so connected with the others as to form and indivisible whole which cannot be taken to pieces without altering its nature: Horwood v Millar's Timber and Trading Co Ltd. If the elimination of the invalid promises changes the extent only but not the kind of the contract, the valid promises are severable: Putsman v Taylor."
26That statement has been cited with approval in the High Court and the Privy Council (see Humphries and another v The Proprietors "Surfers Palms North" Group Titles Plan 1955 [1994] HCA 21; (1994) 179 CLR 597 at 618-619).
27The effect of holding the concluding words of clause 45.1 to be void is essentially that the fourth step of the regime (which can only arise if the decision of the expert meets a certain description and is thereby not final and binding) is taken away, such that the parties can no longer require the dispute to be referred to arbitration. Instead, they can resort to the courts or the other avenues provided for under Part 3A of the Home Building Act, as appropriate. There is no effect upon any of the first three steps of the regime, each of which can be, but are not necessarily, final. In particular, there is no effect upon the circumstances in which the determination of the expert is, or is not, final and binding.
28Whilst all four steps are contained in the regime under clause 45.1, I do not think, to adopt the words of Allsop P in United Group Rail Services Ltd v Rail Corporation New South Wales (supra) at [96], that there is an "unseverable nexus" between the fourth step and the earlier steps. The removal of the fourth step, leaving the parties with alternative means of dealing with the dispute and leaving the first three steps unchanged, does not seem to me to give the parties a regime of a character significantly different from that they agreed to. Put another way, the removal of the void provision does not alter the essential nature of the agreed regime (see McFarlane v Daniell (supra) at 345).
29It follows from the above that clause 45.1, up to the point where an expert determination takes place, remains binding upon the parties to the contract. Whilst it is possible that expert determination might not yield a decision that is final and binding, it is my view that the parties should be held to their bargain that certain disputes shall be determined in accordance with the clause 45.1 regime (see Cessnock City Council v Aviation and Leisure Corporation Pty Ltd [2012] NSWSC 221 at [31] per Hammerschlag J). It is prima facie inappropriate that such disputes are sought to be litigated in court. The position is a fortiori where, as in this case, the agreed contractual regime has already been invoked. In those circumstances, the commencement of court proceedings creates a situation of duplicity, and may be considered vexatious, where issues are simultaneously subject to determination in different places. There is no doubt that in the present case, issues such as whether the defendant was entitled to take over the works pursuant to clause 44.1 of the contract, and whether $902,207 was due from the plaintiff to the defendant in accordance with the Superintendent's certificate under clause 44.4 of the contract, are currently the subject of both these proceedings and the expert determination that has been required (by the plaintiff) under clause 45.1 of the contract.
30In my opinion, neither the possibility of litigation in this Court if the determination of the expert is not final and binding, nor the possibility (which at present seems to me rather remote) that discretionary relief might be sought in these proceedings, affords a good reason to permit the proceedings to continue. In all the circumstances, I consider that it is appropriate for the proceedings to be stayed until further order of the Court, so as to allow the matters in dispute to be further dealt with in accordance with the agreed regime. The Court will make such an order, together with an order that the plaintiff pay the defendant's costs of the Notice of Motion.
31The defendant sought an order that, if successful, it should have its costs paid on the indemnity basis. It was submitted that indemnity costs was justified in circumstances where the plaintiff was promptly put on notice that the proceedings were an abuse of process and liable to be stayed, the plaintiff did not accept the defendant's proposal that all disputes in relation to the contract or project be determined by the Court, and the plaintiff only belatedly raised the argument that clause 45 of the contract was void. There is some force in that submission.
32Nevertheless, the fact remains that the fate of the stay application was essentially dependent upon whether clause 45.1 was rendered wholly void by virtue of s 7C of the Home Building Act. Whilst that argument was only raised by the plaintiff very late in the piece, it was a substantial argument, properly agitated. I do not think that a special costs order is warranted. The plaintiff should pay the defendant's costs of the Notice of Motion on the ordinary basis.
