"The next question we shall address is why did Mr McGovern leave Spicer McColl. In his witness statement Mr McGovern states that he could not see himself achieving the same earnings as with Mr Owen, that he was working an extra hour every day, that he worked and extra half day a week, and that his journey to and from work took between two to three hours each day. Whether Mr McGovern was right or wrong about his first reason [and we interpose that there was an issue as to what his earnings would have been with Spicer McColl had he stayed with them] , we believe that these were the true reasons for Mr McGovern's departure and we reject the contention that Mr McGovern intended to set up his own business from the start and that the job at Spicer McColl was a stop-gap."
"As Mr McGovern had a permanent job with Spicer McColl and as he brought it to an end by his own volition, we conclude that any loss or expense incurred by Mr McGovern in setting up his own business does not flow from the earlier dismissal. In other words the chain of causation is broken."
"The Tribunal would in any event have had a problem in awarding Mr McGovern compensation for the differential loss of income as there was no credible evidence of such continuing. It would be pure speculation to come up with any figure. Some hypotheses have to be constructed when awarding compensation, but we do not see it as our role to "pick a figure out of thin air" which is what we would have to do."
"As soon as the applicant obtains permanent alternative employment paying the same or more than his pre-dismissal earnings, his loss attributable to the action taken by the respondent employer ceases. It cannot be revived if he then loses that employment either through his own action or that of his new employer. Neither can the respondent employer rely on the employee's increased earnings to reduce the loss sustained prior to his taking new employment. The chain of causation has been broken."
"19. I consider that statement needs qualification. No doubt in many cases a loss consequent upon unfair dismissal will cease when an applicant gets employment of a permanent nature at an equivalent or higher level of salary enjoyed when dismissed. But to regard such an event as always and in all cases putting an end to the attribution of the loss to the termination of employment cannot lead in some cases to an award which is just and equitable. 20. Although causation is primarily a question of fact, the principle to be applied in deciding whether the connection between a cause, such as unfair dismissal, and its consequences is sufficient to found a legal claim for loss or damage is a question of law. The question for the industrial tribunal was whether the unfair dismissal could be regarded as a continuing cause of loss when she was subsequently dismissed by her new employer with no right of compensation after a month or two in her new employment. To treat the consequences of unfair dismissal as ceasing automatically when other employment supervenes is to treat as that effective cause that which is simply closest in time."
"26. We have been referred to a number of cases where the Employment Appeal Tribunal has appeared to lay down rules for the calculation of compensation, with particular reference to cases where the employee obtains other employment before the date when compensation is assessed. One rule appears not to be in dispute: that the employee's loss is to be assessed at the date of the remedy hearing. But it is also true, as was said by the Employment Appeal Tribunal in Whelan v Richardson , that that date is necessarily arbitrary. One must avoid, if one can, in giving rise to arbitrary results. 27. Other rules adopted by the Employment Appeal Tribunal, if such they be, are at the most guidance. What has to be assessed in terms ofsection 123(1) of the Employment Rights Act 1996 is such amount as the tribunal considers just and equitable in all the circumstances, having regard to the loss sustained by the complainant in consequence of the dismissal, in so far as that loss is attributable to action taken by the employer. That includes a test of causation, or perhaps the same test twice over, once by reason of the works 'in consequence of' and a second time in the words 'attributable to'. 28. That is the ordinary common sense test if the common law. Was the loss in question caused by the unfair dismissal or by some other cause? The tribunal must ask itself and answer that question, and then ask what amount it is just and equitable for the employee to recover."
"It is very important, and sometime difficult, to remember that where a right of appeal is confined to questions of law the appellate Tribunal must loyally accept the findings of fact with which it is presented and where, as can happened from time to time, it is convinced that it would have reached a different conclusion of fact, it must resist the strong temptation to treat what are in truth findings of fact as holdings of law or mixed findings of fact and law. The correct approach involves a recognition that Parliament has constituted the Industrial Tribunal the only Tribunal of fact and that conclusions of fact must by accepted unless it is apparent that, on the evidence, no reasonable Tribunal could have reached them. If such be the case, and happily it is a rarity, the Tribunal, which is to be assumed to be a reasonable Tribunal, must have misdirected itself in law and the Employment Appeal Tribunal will be entitled to intervene."
