"27. Mrs Egerton made two specific claims of sexual harassment, which she said had occurred in April 1996.
"8. I was proceeding to call my Third Witness of Fact [who he does not identify, but we will take it to be Pat Crampton] when the Chairman interrupted and stated 'is there any point in calling any further evidence'. I responded by indicating that the evidence of the other witnesses I was about to call namely two other witnesses plus the return of Miss Hatton [who, I interpose, was the other lady who was making the allegations, thus the other Applicant] would point out the way in which those persons had been treated by Mr Ashton the person who was alleged to have been responsible for the sex discrimination and the treatment of Mrs Egerton. I pointed out that these witnesses would be very pertinent with regard to their comments on the way they had been treated by Mr Ashton and their observations of him and their knowledge of him. I was informed by the Chairman that 'it was a waste of time I could call them if I wanted to but it was clearly a waste of time to do so'."
"... Where there is an allegation of bias based on the conduct of one or more members of a 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, at 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 decision by the Tribunal when that party has not yet presented all his evidence relevant to the point or had the opportunity of addressing the Tribunal on that evidence."
"There are no doubt a variety of ways in which tribunal members may address questions to witnesses, and some may no doubt appear more forceful than others. It is, not however, suggested that [the witness] was forced to give answers which were untrue, or that he conceded points against his will."
"On the principle that not only must justice be done but be seen to be done, it is open to a party to complain to the EAT that the Industrial Tribunal in the conduct of the proceedings had given the appearance of bias: Peter Simper & Co Ltd v Cooke[1986] IRLR 19 . The test for establishing apparent or potential bias was formulated by Lord Gough of Cheevely in the Queen v Gough [1993] Appeal Cases 646, 670 in this way:
"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 the 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 the 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 a part of the issue under consideration by him."
"It seems to us that there are here conflicting policy considerations. On the one hand Mr Oldham submits if the factual conflict raised in this appeal cannot be resolved in the usual way by the Appeal Tribunal hearing the contestants and determining the factual issues, it will be unjust if the appellant's account is rejected and the Industrial Tribunal's accepted. The appellant has a basic right to have his case heard by an independent and impartial Tribunal.
"It is an essential principle of natural justice. Without the opportunity to challenge the Industrial Tribunal members' account, his appeal may fail simply because there is a dispute as to the facts on which he seeks to rely on prosecuting his appeal. Against that is the universal acceptance that it would be a wholly undesirable prospect to require persons who sit in a judicial capacity to appear ultimately in the witness box to justify their conduct of proceedings which took place before then."
"2. As a matter of policy we are faced with a choice. In our view the undesirability of compelling members of Industrial Tribunals to give evidence in the way suggested by Mr Oldham, that way is the possible prejudice caused to the Appellant.
