“We do not agree that Mr Harris’s report goes beyond the permitted scope of the quantum expert evidence. Your assertion that this is ‘admitted in paragraph 3.3 of the Harris report’ is plainly unsustainable. Paragraph 3.3 of Mr Harris’s report explicitly states that he was not asked to consider the issues listed there in regard to assessing the questions listed in paragraph 3.1 and 3.2. All three ‘illustrative examples’ given in your letter are points that bear obvious relevance to the feasibility and overall financial outcome of the counterfactual trades within the counterfactual scenario presented by your client. It would be unduly artificial for the parties and their experts to ignore the broader factual scenario in which the counterfactual trades would have occurred when assessing these issues. Such a narrow approach would not assist the court. In addition, contrary to the assertion in your letter, the points addressed by Mr Harris properly arise out of our client’s current pleaded case. However, without waiving privilege, this will be put beyond doubt in our client’s draft re-re-amended defence. Your client’s quantum expert Mr Ammermann will, therefore, need to address these issues in due course. To the extent your client is not willing for Mr Ammermann to deal with these issues now, we are preached prepared to instruct Mr Harris not to raise them at the joint meeting scheduled for2 November 2023 . However, that approach is inefficient given the inevitability that Mr Ammermann will need to address them at some point, most obviously in his reply expert report.”
