“5. Where the issue of case management that arises is whether to split trials the approach called for is an essentially pragmatic one, and there are various (some competing) considerations. These considerations seem to me to include whether the prospective advantage of saving the costs of an investigation of quantum if liability is not established outweighs the likelihood of increased aggregate costs if liability is established and a further trial is necessary; what are likely to be the advantages and disadvantages in terms of trial preparation and management; whether a split trial will impose unnecessary inconvenience and strain on witnesses who may be required in both trials; whether a single trial to deal with both liability and quantum will lead to excessive complexity and diffusion of issues, or place an undue burden on the Judge hearing the case; whether a split may cause particular prejudice to one or other of the parties (for example by delaying any ultimate award of compensation or damages); whether there are difficulties of defining an appropriate split or whether a clean split is possible; what weight is to be given to the risk of duplication, delay and the disadvantage of bifurcated appellate process; generally, what is perceived to offer the best course to ensure that the whole matter is adjudicated as fairly, quickly and efficiently as possible. 6. Other factors to be derived from the guidance given byCPR Rule 1.4 , which reflect a common sense and a pragmatic approach, may include whether a split would assist or discourage mediation and/or settlement; and whether an order for a split late in the day after the expenditure of time and costs might actually increase costs. 7. All these sorts of factors seem to me to be potentially relevant and need to be taken into account in what is essentially a pragmatic balancing exercise in assessing how the case is likely to unfold according to whether there is or is not a split. 8. It follows that each case falls to be assessed by reference to its own facts, features and peculiarities. Further, the assessment has to be made before the Court can responsibly take any reliable view as to the prospects of success, and thus as to whether quantum will be a live issue or not.”
“Thus in the CAT proceedings, as is not uncommon in stand-alone competition cases, issues of the quantum of damages can be split off to be determined at a separate trial after determination of liability.”
“The [damages] counterfactual is closely related and involves a similar exercise to the counterfactual undertaken to determine whether a restriction constitutes a restriction of competition … The counterfactual in the damages exercise involves assessing the harm that the claimant has sustained measured against what would have happened had the wrong to the claimant never occurred.”
