""47. DISPUTE RESOLUTION 47.1 Notice of Dispute If a dispute between the Contractor and the Principal arises out of or in connection with the Contract including a dispute concerning a direction given by the Superintendent, then either party shall deliver by hand or send by certified mail to the other party and to the Superintendent a notice of dispute in writing adequately identifying and providing details of the dispute. Notwithstanding the existence of a dispute, the Principal and the Contractor shall continue to perform the Contract, and subject to Clause 44, the Contractor shall continue with the work under the Contract and the Principal and the Contractor shall continue to comply with Clause 42.1. A claim in tort, under statute or for restitution based on unjust enrichment or for rectification or frustration, may be included in an arbitration. 47.2 Further Steps Required Before Proceedings A party served with a notice of dispute may give a written response to the notice to the other party and the Superintendent within 28 days of the receipt of the notice. Within 42 days of the service on the Superintendent of a notice of dispute or within 14 days of the receipt by the Superintendent of the written response, whichever is the earlier, the Superintendent shall give to each party the Superintendent's written decision on the dispute, together with reasons for the decision. If either party is dissatisfied with the decision of the Superintendent, or if the Superintendent fails to give a written decision on the dispute within the time required under Clause 47.2 the parties shall, within 14 days of the date of receipt of the decision, or within 14 days of the date upon which the decision should have been given by the Superintendent confer at least once to attempt to resolve the dispute and failing resolution of the dispute to explore and if possible agree on methods of resolving the dispute by other means. At any such conference, each party shall be represented by a person having authority to agree to a resolution of the dispute. In the event that the dispute cannot be so resolved or if at any time after the Superintendent has given a decision either party considers that the other party is not making reasonable efforts to resolve the dispute, either party may, by notice in writing delivered by hand or sent by certified mail to the other party, refer such dispute to arbitration or litigation. 47.3 Arbitration Arbitration shall be effected by a single arbitrator who shall be nominated by the person named in the Annexure, or if no person is named, by the Chairperson for the time being of the Chapter of the Institute of Arbitrators Australia in the State or Territory named in the Annexure. Such arbitration shall be held in the State or Territory stated in the Annexure. Unless the parties agree in writing, any person agreed upon by the parties to resolve the dispute pursuant to Clause 47.2 shall not be appointed as an arbitrator, nor may that person be called as a witness by either party in any proceedings. Notwithstanding Clause 42.9, the arbitrator may award whatever interest the arbitrator considers reasonable. If one party has overpaid the other, whether pursuant to a Superintendent's certificate or not and whether under a mistake of law or fact, the arbitrator may order repayment together with interest. 47.4 Summary or Urgent Relief Nothing herein shall prejudice the right of a party to institute proceedings to enforce payment due under Clause 42 or to seek urgent injunctive or declaratory relief in respect of a dispute under Clause 47 or any matter arising under the Contract." They accepted that a disputed claim for sums due under an uncertified claim fell within the terms of the first paragraph of cl. 47.1 and that this was an arbitration agreement for the purposes of s.53[3]. They contended, however, that a claim in respect of an uncertified claim should not be stayed, because it was specifically saved by cl. 47(4). Where the contract provides for the Contractor to sue to enforce payment under cl. 42 this right should not be denied simply because the Principal raised by way of defence to this claim matters which, in a different context, would be arbitrable and might therefore warrant a stay. It was pointed out that payments recovered in this way were received by the Contractor on account only, so that, in the event that it should appear that the certified sum or the uncertified claim were erroneous or unjustified, this sum would be recoverable in due course.[4]
