In the event of any doubt, dispute, or difference arising or happening, relating to, touching, or concerning the works, or any portion thereof, or the value, quantities, qualities, description, or manner of work done and executed by the Contractor or relating to, touching, or concerning the exercise of any of the powers of the Commissioner, the Chief Engineer for Railways, the Superintending Officer, or any other person employed by the Commissioner under this contract, or any claim made by the Contractor in consequence thereof, or in any way arising therefrom or relating to, touching or concerning any inconsistency, ambiguity, or variance in, or the meaning or intention of the contract or relating to, touching, or concerning any certificate, order or award which may be made by the Chief Engineer for Railways, or in anywise whatsoever relating to the interests of the Commissioner or of the Contractor in the premises, or to any alleged breach of contract, or touching or concerning any other matter or thing in any way connected with or relating to this contract or anything therein contained or provided, every such doubt, dispute, or difference, shall from time to time, and so far as the same has not herein before been left to the decision or determination of the Chief Engineer for Railways, be referred to and settled and decided by the Chief Engineer for Railways, whose decision thereon shall be final and conclusive.
The clause then contains a proviso under which the contractor is given power, if dissatisfied with "any certificate or decision of the Chief Engineer for Railways made, given or pronounced touching or concerning the mode or manner of measuring the works, or the prices to be paid for any work done, for which none of the prices in the schedule shall be applicable" to give to the Commissioner "notice in writing, setting forth the grounds of his objection and requiring that the matter be referred by way of appeal hereunder". The proviso goes on to say that in such a case, such certificate or decision shall be referred by way of appeal to the award, order, determination or decision of either the Engineer-in-Chief for the State of South Australia or the Chief Engineer of the Harbors Board of that State, as the Minister of Works for the State shall appoint after the lapse of one month from the date when the Chief Engineer for Railways shall have certified that the works have been finally and satisfactorily completed and fully delivered to the Commissioner, "and the Arbitrator so appointed shall be the sole arbitrator of the matters in this proviso mentioned as referable by way of appeal".
