"Now we think that when we, in this appellate tribunal, approach a consideration of the validity of a decision by an industrial tribunal, or by the appropriate officer of an industrial tribunal, upon a matter of discretion, we must look for two things, the discovery of either of which will be sufficient to entitle us to overturn the exercise of that discretion. Either we must find, in order so to do, that the tribunal, or its chairman, has taken some matter which it was improper to take into account or has failed to take into account some matter which it was necessary to take into account in order that discretion might be properly exercised; or, alternatively if we do not find that, that the decision which was made by the tribunal, or its chairman, in the exercise of its discretion was so far beyond what any reasonable tribunal or chairman could have decided that we are entitled to reject it as perverse."
"Instead we have tried to follow the guidance in Automobile Proprietory Ltd v Healey and, insofar as we are capable of doing so objectively, answer the question posed by the Employment Appeal Tribunal in Peter Simper and Co Ltd v Cooke[1986] IRLR 19 ; "Would the reasonable observer present at the hearing, not being a party, or associated with a party, to the proceedings but knowing the issues, reasonably gain the impression of bias?" We all agree that the respondent's complaints do not meet that test. For their part, having considered the test, what happened at the hearing and the letter of 30 August, neither lay member has any reservation about the way in which the proceedings had been conducted by the Chairman. Had that been the case, the Chairman would have advised that the application for a re-hearing should be allowed."
"In conclusion I wish to express my understanding of the law as follows. I think it possible and desirable that the same test should be applied in all cases of apparent bias, whether concerned with justices or members of other inferior tribunals, or with jurors or without arbitrators. ... I think it unnecessary, in formulating the appropriate test to require that the court should look at the matter through the eyes of reasonable man, because the court in cases as such as these personifies the reasonable man; in any event the court has first to ascertain the relevant circumstances from the available evidence, knowledge of which would not necessary be available to an observer in court at the relevant time. Finally, for the avoidance of doubt, I prefer to state the test in terms of real danger rather than real likelihood, to ensure that the court is thinking in terms of possibility rather than probability of bias. Accordingly, having ascertained the relevant circumstances, the court should ask itself whether, having regard to those circumstances, there was a real danger of bias on that part of the relevant member of the tribunal in question, in the sense that he might unfairly regard (or have unfairly regarded) with favour, or disfavour, the case of the party to the issue under consideration by him; ..."
"It is common ground between both sides that the proper approach to the issue of bias is that justice must not only be done but must be manifestly seen to be done. There must be no appearance of bias. The test is a question of mixed fact and law; would the reasonable and disinterested observer present at the hearing, not being a party or associated with the party to the proceedings, but knowing the issues, reasonably gain the impression of bias? The reasonable and disinterested lay observer has been likened in other aspects of the law "the man on Clapham Omnibus" or the "officious bystander"."
"We think it right to stress the highly unusual facts of this case. Save in extraordinary circumstances, cannot be right for a litigant, unhappy with what he believed to be the indications from the Tribunal as to how the case is progressing to apply, in the middle of the case, for a re-hearing before another Tribunal. It is, in our view, undesirable that the Tribunal accused of giving the opinion of bias should be asked to itself to adjudicate on that matter. The dissatisfied litigant should ordinarily await the decision and then, if he thinks it appropriate, he should make his dissatisfaction with the conduct of the case by the tribunal a ground of appeal."
"In the exercise of jurisdiction outside the field of criminal law, the only restrictions on cross-examination are those general and well defined exclusionary rules which govern the admissibility of relevant evidence (as to which reference make conveniently be had to cross on evidence 5th Edition 1979 page 17); beyond those restrictions there is no discretion on the civil side to exclude cross-examination on relevant matters."
"The respondent [ employer ] may yet satisfy us that is was either due to a chapter of accidents, carelessness, incompetence or some other reason."
