Losses in UK Law

Mr. Stuart-Smith says that it is any detriment, liability or loss capable of assessment in money terms and it includes liabilities which may arise on a contingency, particularly a contingency over which the plaintiff has no control; things like loss of earning capacity, loss of a chance or bargain, loss of profit, losses incurred from onerous provisions or covenants in leases. They are all illustrations of a kind of loss which is meant by "actual" damage.

Subject to any express or implied statutory rule, of which there is none here, the ordinary way to ascertain the profits or losses of a business is to apply accepted principles of commercial accountancy. That is the very purpose for which such principles are formulated. As has often been pointed out, such principles are not static : they may be modified, refined and elaborated over time as circumstances change and accounting insights sharpen.

In an action for personal injuries the damages are always divided into two main parts. First, there is what is referred to as special damage which has to be specially pleaded and proved. This consists of out-of-pocket expenses and loss of earnings incurred down to the date of trial, and is generally capable of substantially exact calculation. Secondly, there is general damage which the law implies and is not specially pleaded.
