“Where a party has disclosed an expert’s report, any party may use that expert’s report as evidence at the trial.”
“Expert evidence shall be restricted to that which is reasonably required to resolve the proceedings”
“6. In my judgment, the answer to Mr Sutherland's [Gurney’s Counsel] two points can be found inCPR 35.11 itself. It only applies where party A has already disclosed an expert's report and party B wants to rely on it as evidence at the trial. The disclosure of party A's report could only have occurred in accordance withCPR 35.4 . In other words, it is a fundamental assumption withinCPR 35.11 that there has already been compliance withCPR 35.4 , and the report which party B now wishes to use is one for which the court has already given permission. In such circumstances, it is not necessary for party B to seek permission all over again; party B merely wishes to use a report for which permission has already been given. 7. Similarly, becauseCPR 35.11 assumes that party A's report has been disclosed in accordance withCPR 35.4 , it does not matter whether, sometime after disclosure of that report, party A ceased to be a party to the proceedings. The reference to "a party [that] has disclosed an expert's report" inCPR 35.11 cannot be limited to those who happen to be parties to the proceedings at the time that that report is sought to be used by another: there is nothing in the rule which could limit its scope in that way. The reference in r.35.11 is to any party who has disclosed a report in accordance with r.35.4, whether they subsequently remain a party to the proceedings or not. 8. Prima facie, therefore, as a matter of straightforward construction of the CPR, Gleeds can use the engineering reports disclosed by Pearson, Styles and Wood, GMK, and Fourways. Moreover, I should say that, in my judgment, such a result is generally in accordance with the over-riding objective atCPR 1.1 . It would be artificial, and possibly even misleading, in a case of this sort, for the court to have no regard whatsoever to the reports of the other experts, or the part played by those other experts in reaching the detailed contents of theCPR 35.12 joint statement…. 11. Finally I should add this. Although I consider that, in general terms, it would be artificial for me to ignore entirely the views of the other engineering experts, it should not be thought that any great weight can be attached to the views of any expert who will not give oral evidence at the trial. Moreover, the fact that the majority of the engineering reports reach broadly similar conclusions on causation is also, of itself, of little account: cases of this kind are decided by reference to the quality of the expert evidence adduced at trial, and in particular the oral evidence. They are not determined by weight of numbers.”
