". . . it was no part of their duty to substitute their own evaluation of a witness for that of the employer, particularly when that evaluation had been confirmed following two appeals, nevertheless they considered that they would be failing in their duty under section 57 of the Act if they did not consider certain procedural matters which gave rise to concern."
"The matters which concern the Tribunal were, firstly, the fact that Mr Liddle's letter of4 September 1990 notifying the applicant that a disciplinary hearing had been arranged was written before there had been any investigation whatsoever of the initial report from Mr Lake. Secondly, that the applicant had neither been interviewed or asked whether he wished to make any statement before the disciplinary hearing which meant that any points which he wished to raise had not been investigated before the disciplinary hearing took place, and thirdly, that the circumstances and manner in which the reconstruction arranged by Mr Liddle took place were unsatisfactory inasmuch as it appeared that no attempt was made to check that the vehicles were positioned in precisely the manner in which Mr Laidler and the applicant stated they had been, that no check was made to see precisely what could be seen when the hopper was being interfered with and that the applicant was unaware that the reconstruction was taking place and was certainly not given the opportunity of being present."
"Taking all these matters into account and without in any way attempting to substitute their own evaluation for that of the respondent the Tribunal were of the unanimous view that the procedural defects to which they had referred were such as to render the applicant's dismissal unfair and in consequence they were of the unanimous view that he was unfairly dismissed."
"There was an appeal hearing conducted by Mr Jameson on13 September 1990 at which Mr Liddle's original decision was upheld and the applicant again exercised his second right of appeal and a second (final) appeal hearing took place on26 September 1990 in the presence of 3 Managers of the respondent when they also confirmed Mr Liddle's decision."
"We think it right to stress the highly unusual facts of this case. Save in extraordinary circumstances, it cannot be right for a litigant, unhappy with what he believes to be the indications from the Tribunal as to how the case is progressing, to apply, in the middle of a 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 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."
"We accept that there is jurisdiction for a tribunal to discontinue a hearing and order a re-hearing. But those cases also make it clear that that power should be exercised most sparingly and only for very good reason, a bare allegation of bias is not sufficient. We take it to be axiomatic that justice before a tribunal must not only be done but also be manifestly seen to be done. That applies as much, in our view, to a tribunal such as the industrial tribunal as it does to a formal court of law. Not only must there be no bias on the part of the tribunal but also the tribunal must not give the appearance of bias. Where there is an allegation of bias based on the conduct of one or more members of the tribunal at a hearing the test is, in our view, an objective one, 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. That impression may be given by the appearance of a closed mind against a party on a matter which calls for a decision by the tribunal when that party has not yet presented all his evidence relevant to the point or had the opportunity of addressing a tribunal on that evidence."
"The answer to that question depends not upon what actually was done but upon what might appear to be done. Nothing is to be done which creates even a suspicion that there has been an improper interference with the course of justice. Speaking for myself, I accept the statements contained in the justices' affidavit, but they show very clearly that the deputy clerk was connected with the case in a capacity which made it right that he should scrupulously abstain from referring to the matter in any way, although he retired with the justices; in other words, his one position was such that he could not, if he had been required to do so, discharge the duties which his other position involved. His twofold position was a manifest contradiction. In those circumstances I am satisfied that the conviction must be quashed, unless it can be shown that the applicant or his solicitor was aware of the point that might be taken, refrained from taking it, and took his chance of an acquittal on the facts, and then, on a conviction being recorded, decided to take the point. On the facts I am satisfied there has been no waiver of the irregularity, and that being so, the rule must be made absolute and the conviction quashed."
