“[31] I derive the following principles from authorities in relation to an inquiry as to damages: (1) A successful claimant is entitled, by way of compensation, to that sum of money which will put him in the same position he would have been in if he had not sustained the wrong, see Livingstone v Rawyards Coal Co. (1880) 5 App.Cas., 25 per Lord Blackburn at 39. (2) The claimant has the burden of proving the loss, see General Tire and Rubber Company v Firestone Tyre and Rubber Company Limited[1976] RPC 197 , at 212. (3) The defendant being a wrongdoer, damages should be liberally assessed but the object is to compensate the claimant, not punish the defendant, see General Tire at p.212. (4) The claimant is entitled to recover loss that was (i) foreseeable, (ii) caused by the wrong and (iii) not excluded from recovery by public or social policy, see Gerber Garment Technology Inc v Lectra Systems Ltd[1997] RPC 443 , at 452. (5) In relation to causation, it is not enough for the claimant to show that the loss would not have occurred but for the tort. The tort must be, as a matter of common sense, a cause of the loss. It is not necessary for the tort to be the sole or dominant cause of the loss, see Gerber at p.452. (6) An inquiry will generally require the court to make an assessment of what would have happened had the tort not been committed and to compare that with what actually happened. It may also require the court to make a comparison between, on the one hand, future events that would have been expected to occur had the tort not been committed and, on the other hand, events that are expected to occur, the tort having been committed. Not much in the way of accuracy is to be expected bearing in mind all the uncertainties of quantification. See Gerber at first instance[1995] RPC 383 , per Jacob J, at 395-396. (7) Where the claimant has to prove a causal link between an act done by the defendant and the loss sustained by the claimant, the court must determine such causation on the balance of probabilities. If on balance the act caused the loss, the claimant is entitled to be compensated in full for the loss. It is irrelevant whether the court thinks that the balance only just tips in favour of the claimant or that the causation claimed is overwhelmingly likely, see Allied Maples Group v Simmons & Simmons[1995] WLR 1602 , at 1609-1610. (8) Where quantification of the claimant’s loss depends on future uncertain events, such questions are decided not on the balance of probability but on the court’s assessment, often expressed in percentage terms, of the loss eventuating. This may depend in part on the hypothetical acts of a third party, see Allied Maples at 1610. (9) Where the claim for past loss depends on the hypothetical act of a third party, i.e. the claimant’s case is that if the tort had not been committed the third party would have acted to the benefit of the claimant (or would have prevented a loss) in some way, the claimant need only show that he had a substantial chance, rather than a speculative one, of enjoying the benefit conferred by the third party. Once past this hurdle, the likelihood that the benefit or opportunity would have occurred is relevant only to the quantification of damages. See Allied Maples at 1611-1614.”
