“I also note that in 1991 the area of the site which was subject to the rent, was contested at a contested rent review. The assessment for the landlord then, was that the relevant area was 4,800 yards; Mr Hotchin says it is actually slightly less, 4,600 and Mr Cattrell for the tenant gave the area at 3330 at that time. Mr Simpson, a qualified surveyor appointed as the independent arbitrator by the parties, therefore, with much greater experience than a county court judge would have of assessing relevant areas, who it can be seen from C11 of the court’s bundle, inspected the premises. He did not give a reasoned decision and it is not clear whether he carried out any measurements. He accepted Mr Cattrell’s contentions for the relevant area to which the appropriate rent should be applied. That seems to me to be very convincing evidence as to the appropriate usable area that the court ought to adopt for the purpose of these proceedings.”
“Noting that this matter has been contested in 1991 and Mr Cattrell’s evidence was that the site has not changed a great deal, if at all, since then, he having had familiarity with the site ever since, … on the balance of probabilities on the available evidence I have, the usable area is that which was found by Mr Simpson as 3330 yards.”
“It is submitted that in truth the Learned Judge did not properly prefer one expert’s view over the other but, rather, placed great weight on the fact that the independent arbitrator from [1991] had adopted Mr Cattrell’s evidence. It is submitted that the Learned Judge erred in placing reliance on a witness who had not been heard or cross examined, who had expressly stated that he gave no reasons for his decision and when there was no evidence that he had measured the site himself.”
“In principle the judgment, verdict or award of another tribunal is not admissible evidence to prove a fact in issue or a fact relevant to the issue in other proceedings between different parties”
“… Mr. Clark, if tendered as an expert witness, would be liable to cross-examination like any other expert. Once one goes to that point, however, one has moved a long way from the admissibility of the award as such. If Mr. Clark can be called on to justify his opinion of the rental value of the comparable property, that opinion ceases to have any evidential value. His opinion would presumably be based on the evidence of real comparables presented to him in his own arbitration. But Mr. Clark is not in a position to give admissible evidence of those comparables. He can only say what he was told by the witnesses at his arbitration. It follows that there will be no admissible evidence to support his opinion. Even if Mr. Clark or someone else were in a position to give admissible evidence of the comparables that support his opinion, I think that his award would still be inadmissible on another ground. It would involve a collateral inquiry as to whether Mr. Clark came to the right decision in his own arbitration. The result of such an inquiry would, in my judgment, have insufficient relevance to the issue in the present arbitration to justify undertaking it. So far as the comparables relied on by Mr. Clark are relevant to the value of Westminster City Hall they could have been used as such by the landlord's experts. In so far as they would not have been relevant I do not think they can be smuggled in by using them to establish Mr. Clark's opinion of the value of a comparable property and then using that conclusion to support a valuation of Westminster City Hall.”
“Properly analysed I think that the arbitrator's award has in itself insufficient weight to justify the exploration of otherwise irrelevant issues which its admissibility would require.”
