"10. The continuing loss of wages for the remainder of the period for which the Applicant claims has not been the subject of compensation for unfair dismissal and is therefore the subject of a claim for damages as a result of disability discrimination. We consider that the Applicant has made few, it any, attempts to secure alternative employment. On the assumption that he has remained disabled, however, we do not think that his failure to mitigate his loss, to date is unreasonable. We wish to emphasise, however, that this consideration only applies to the situation which we are considering to the date of this hearing. Had we been asked to consider ongoing compensation for future loss, we would have wished to receive medical evidence in support of a prognosis of the length of time for which the Applicant's disability might be expected to continue. In our view, that is a central factor in deciding upon his duty to mitigate in the future."
"(4) The industrial tribunal erred in law in holding that it had jurisdiction to grant a review of the earlier decision and to vary it. The power to grant a review on the grounds "that the interests of justice require such a review" is in very wide terms. It is, however, a power which should be cautiously exercised. As was observed by Phillips J in Flint v Eastern Electricity Board [1975] I.C.R. 395, 404, the interests of justice include, not only the interests of the person seeking a review, but also the interests of a person resisting a review on the grounds that "once a hearing which has been fairly conducted is complete, that should be the end of the matter."
"[it] should only be in unusual cases that the employee, the applicant before the tribunal, is able to have a second bite at the cherry."
"As it seems to us the fundamental question is whether or not the industrial tribunal's decision that the employee had failed to mitigate her loss was reached after she had had a fair and proper opportunity to present her case on the point, being aware that it was a point which was in issue. We do not think that it is appropriate for an industrial tribunal to review their decision simply because it is said there was an error of law oil its face. If the matter has been ventilated and properly argued, then errors of law of that kind fall to be corrected by this appeal tribunal. If, on the other hand, due to an oversight or to some procedural occurrence one or other party can with substance say that he has not had a fair opportunity to present his argument on a point of substance, then that is a procedural shortcoming in the proceedings before the tribunal which, in our view, can be correctly dealt with by a review under rule 10 of Schedule 1 to theIndustrial Tribunals (Rules of Procedure) Regulations 1980 , however important the point of law or fact may be. In essence, the review procedure enables errors occurring in the course of the proceedings to be corrected but would not be normally be appropriate when the proceedings had given both parties a fair opportunity to present their case and the decision had been reached in the light of all relevant argument."
"17. Although this is not a case where a party has been denied a fair opportunity to present its case before the Tribunal, it seems to us that the "dangerous path" argument adverted to by Mummery J is less persuasive when, as in this case, the mistake was made by both parties and by the Chairman. If the error is more than a minor one, that does not, in the light of Trimble prevent a review. It being agreed that this error would have been corrected by the EAT if an appeal had been launched and a necessary extension of time given, it seems to us, in accordance with rule 10, that using the review procedure to remedy the error saves expense and helps to ensure that the matter is dealt with expeditiously. As was said in British Midland Airways, an "appeal takes much longer and is much more expensive"
"The difficulty comes in the relationship between paragraphs (d) and (e) of rule 12. The conclusion I reach is that paragraph (d) cannot be regarded as exhaustive of cases where the ground of the application is the desire to call fresh evidence. It does not, for example, deal with circumstances where, although the evidence could be foreseen, or indeed reasonably or actually known, it was for some reason or another not available. I think that paragraph (e) is intended to be a residual category of case, designed to confer a wide discretion on industrial tribunals. But I do not think that it can embrace a case where the application is on the ground of the desire to call fresh evidence, where it was obvious that that evidence was available and there is no additional factor to be taken into account. In other words, if I may summarise it, paragraphs (d) and (e) are not mutually exclusive, but paragraph (e) at all events must be applied in practice with some regard to the kind of case which is intended to come within paragraph (d). And ordinarily speaking, a case which could be put forward under paragraph (d), and which failed under paragraph (d), would fail under paragraph (e) also. Paragraph (e), I think, exists for the case which, although it may be put forward under paragraph (d), has in it some special additional circumstances which leads to the conclusion that justice does not require a review."
