11 However, his Honour accepted the submission that Elspan and its legal advisers could not seriously assert that it was not assumed throughout the arbitration that the evidence of Mr Ellen was in contest and were under no illusion that Mr Ellen's evidence was in contest in its entirety. No submissions were put to the arbitrator on Browne v Dunn (1893) 6 R 67 principles.
12 On delay his Honour said that he was not satisfied that the delay involved and the matters relied upon in association with it amounted relevantly to misconduct. Further, he was not satisfied that the delay resulted in a particular prejudice to the claimant.
13 It is common enough for judges and arbitrators to prefer the evidence of one witness to the evidence of another and to conclude that evidence given is not true. It is usually unnecessary to go further. A witness may give untrue evidence for a variety of reasons, most of which have to do with the frailty of human memory. It is quite another matter to conclude that a witness, knowing the truth, has deliberately set out to mislead a tribunal of fact. If it is necessary to reach such a conclusion it should be based on the surest of ground. In the present case, the conclusion sprang from the second opponent's error and was reached without the witness being given an opportunity to answer the charge. Based on that foundation the second opponent went on to say that as a consequence he did not accept Mr Ellen's evidence unless it was corroborated by independent documents or other credible material.
14 On a leave application, a question is whether the claimant has arguable grounds for appealing. In my opinion, on the question of misconduct arising from delay and the credit findings to which I have referred, the claimant does have arguable grounds; but see Re Brace [1966] 1 WLR 595; Bulstrode v Trimble [1970] VR 840 at 848; Thomas v Van Den Yssel (1976) 14 SASR 205 at 207 and Seymour v ABC (1977) 19 NSWLR 219; all cases to which Einstein J referred.
15 Einstein J listed those parts of the award which the claimant sought to have set aside on the ground of misconduct, namely claims:
* for higher strength concrete in wall panels;
* in respect of jacking;
* for awning canopies;
* for a hanger crane; and
* for doors.
Those matters and others referred to as plans of steel and concrete buildings, scrap value of steel, special detriment, decommissioning and design fee led to claims for remitter in particular in respect of two matters which it was said the second opponent had not dealt with.
16 It may be, though it is far from clear, that the claim of $3,600 for additional concrete additives (higher strength concrete) was decided, in part, on the basis of the credit findings. In the passage from his reasons already quoted, after referring to the specification, which formed part of the original agreement, the second opponent said that he thought it was reasonable to infer from the claimant's specification that F'c 50 MPa concrete was probably specified for the suspended slabs. It was open for the arbitrator to draw this inference from the specification.
17 Of the claim in respect of jacking the claimant said that the rejection of Mr Ellen's evidence that the amount of deposit reflected in the long span lease of the jacking equipment was a factor leading to the rejection of the higher claim for jacking of $78,300. Einstein J said that the claimant's submission overlooked an important finding of the arbitrator set out in para 32 of the award which was as follows:
"Mr Horley, in his 20 June 1997 report, allowed a sum of $220,940 for preliminaries which included the supervision of jacking. In his 26 June 1997 report in reply, Elspan's expert stated:
'I note the statement in item 23.3 of the affidavit of John Ellen dated 23/6/97 that, in his opinion, the cost of lifting the roof and office slabs was $164,000.00 compared to my assessment of $72,720.00.
In my opinion the difference between the two amounts is due to my allowing the supervisory costs of this process in the preliminaries section. This allowance in preliminaries explains my contention that preliminaries appear high.' "
