9. A hundred and thirteen years ago Lord Wensleydale, when a judge of the King's Bench, in directing a jury said : "It would be most unjust if whenever an accident occurs, juries were to visit the unfortunate cause of it with the amount which they think an equivalent for the mischief done" (Armsworth v. South Eastern Railway Co. (1847) 11 Jurist 758, at p 760 ). And nearly ninety years ago Lord Esher, then Brett J., said that the only legal direction to a jury was that "they must not attempt to give damages to the full amount of perfect compensation for the pecuniary injury, but must take a reasonable view of the case, and give what they consider under all the circumstances a fair compensation" (Rowley v. London and North Western Railway Co. (1873) LR 8 Ex 221, at p 231 ). These cases were referred to by Greer L.J. in Owen v. Sykes (1936) 1 KB 192, at p 198 . And Lord Goddard referred to them in British Transport Commission v. Gourley [1955] UKHL 4; (1956) AC 185 , where he said, "it would be well to remember that it has always been laid down that damages cannot be a perfect compensation" (1956) AC, at p 209 . That, as the rest of his Lordship's remarks make clear, is because the vicissitudes of the future cannot be surely predicted, so that what sum would be perfect compensation cannot be exactly determined. Moreover money cannot make good permanent physical or mental disablements, nor altogether make up for all the deprivations they entail. But, whatever may have been the position a century ago when Parke J. and Lord Esher were speaking, parts of what they said on this matter can, I think, be misapplied to-day. Why, for example, when pecuniary loss is in question is "fair compensation" something less than complete compensation for that loss ? In times when the defendant had to bear the whole burden of a verdict for damages it was natural for juries to hesitate to give a plaintiff all that they might think he ought to have. They might not wish to impose so great a burden on the defendant, or they might not wish to force him into bankruptcy and so prejudice the plaintiff recovering the fruits of his verdict. But to-day there is an insurer to meet most claims of persons injured in motor accidents. Compulsory third party insurance has made sympathy for the defendant or fear of his bankruptcy as misplaced now as sympathy for the plaintiff should be as a substitute for a just appreciation of loss. The removal of what in the past was a check upon generosity overcoming judgment has no doubt led to larger sums being given as damages : but it does not follow that they are always the product of generosity rather than of judgment. Sometimes, no doubt, juries are carried away and bring in verdicts that are extravagantly large. To award "fair compensation" is still a proper formulation of their task. I would, however, respectfully adopt what Dixon J., as he then was, said in Lee Transport Co. Ltd. v. Watson [1940] HCA 27; (1940) 64 CLR 1 : "But, while remembering that fair compensation between the parties is what must be arrived at, it is equally important to keep in mind that after all it is compensatory and that the figures to which in former times courts grew accustomed ought not to govern our notions of what should be awarded in the terms of the money of to-day with its reduced purchasing power" (1940) 64 CLR, at p 14 . That was said twenty years ago. The purchasing power of money has further declined since then and, again to quote Dixon J., "it seems no longer necessary to remind ourselves of the importance of making conservative estimates of the compensation a plaintiff should receive for physical injury" (Pamment v. Pawelski [1949] HCA 43; (1949) 79 CLR 406, at p 411 ). It is in all the conditions of the present time, and they are so very different from those of former times, that the compensation is to be assessed. Some of the considerations to be borne in mind are countervailing factors to the decline in value of money and to the prevalence of insurance. For example, a loss of earning capacity in a particular employment, commonly called loss of wages, was serious indeed in times when it was hard to get work. Today a man incapacitated for one form of employment can often get other employment perhaps just as remunerative : so that he is not in a pecuniary sense worse off. That does not mean, however, that he has not suffered any economic loss. He has ; for he has a reduced earning capacity as the range of activities in which he can be employed is less. It does mean, however, that conventional methods of calculating economic loss by reference simply to wages formerly earned are not appropriate. Or, to take another example, loss to a woman of the opportunity of marriage was more serious in an economic sense in the days when there were few employments open to women than it is to-day. To-day it must be weighed rather in terms of human relationships and social security. And on top of all other changes is the great expansion of social welfare services provided by the State, including invalid and old age pensions, and also assistance in the rehabilitation of the injured and their restoration to a useful life in the community. The value of the social service benefits that a particular individual is receiving may generally be not a matter to be taken into account in the estimation of damages recoverable from a tort-feasor. But in making that estimation jurymen must do so against the background of the conditions of to-day. It is appropriate to quote what Lord Normand said in the House of Lords in Glasgow Corporation v. Kelly (1951) 1 TLR 345 : it was said in reference to solatium under Scots law, but is applicable to damages generally : "I adhere to the opinion that permanent changes in the value of money must be considered in making awards for solatium. No doubt, also, the recent expansion of the social services must be set against the depreciation of the pound sterling. But I agree with the Judges of the First Division that the economic changes of the last 20 or 30 years require that awards of solatium should be considerably greater than they were then (1951) 1 TLR, at p 347 ".
