“…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 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. It was also suggested in argument …that ‘actual’ is really used in contrast to ‘presumed’ or ‘assumed’. Whereas damage is presumed in trespass and libel, it is not presumed in negligence and has to be proved. There has to be some actual damage.”
