There is an obvious difference between cases tried with a jury and cases tried by a judge alone. Where the verdict is that of a jury, it will only be set aside if the appellate court is satisfied that the verdict on damages is such that it is out of all proportion to the circumstances of the case: Mechanical & General Inventions Co. Ltd. v. Austin [7] . Where, however, the award is that of the judge alone, the appeal is by way of rehearing on damages as on all other issues, but as there is generally so much room for individual choice so that the assessment of damages is more like an exercise of discretion than an ordinary act of decision, the appellate court is particularly slow to reverse the trial judge on a question of the amount of damages. It is difficult to lay down any precise rule which will cover all cases, but a good general guide is given by Greer L.J. in Flint v. Lovell [8] . In effect the court, before it interferes with an award of damages, should be satisfied that the judge has acted on a wrong principle of law, or has misapprehended the facts, or has for these or other reasons made a wholly erroneous estimate of the damage suffered. It is not enough that there is a balance of opinion or preference. The scale must go down heavily against the figure attacked if the appellate court is to interfere, whether on the ground of excess or insufficiency.
To say that an award of damages made by a judge must be outrageous, or out of all reason, before an appellate court is entitled to intervene is, I think, with all respect, to state too high a test. However in the present case, in the circumstances stated by my brother Aickin, it should not have been held by the Court of Appeal that the award made by the learned trial judge was a wholly erroneous estimate of the damage suffered, and there was no sufficient ground for the Court of Appeal to have interfered with that award.
