"42 We must, therefore, have regard to what subsequent investigations revealed which led Mr Ancell to change his preliminary impression and to acquire a firm belief that the Applicant was responsible. This is so that we can decide whether the evidence received by Mr Ancell at the disciplinary hearings, together with any further enquiries after his study of Mr Webb's report, rendered reasonable the transition in his mind from a suspicion that either of these two employees could have been responsible, to a belief that the Applicant alone was guilty.
"... an Industrial Tribunal must consider the reasonableness of the employer's conduct, not simply whether they [the members of the Industrial Tribunal] consider the dismissal to be fair.
"... concluded that it was not within the range of responses available to a reasonable employer for Mr Ancell to have balanced the matter in favour of Mrs Sims and against the Applicant. We are left, therefore, with Mr Ancell's assessment of the two employees themselves, i.e. that he believed Mrs Sims and did not believe the Applicant. We do not consider that such a belief arrived at against the weight of a large amount of evidence going the other way, can be reasonably grounded only upon the subjective view of the person holding the disciplinary hearings. In short, when we ask whether there were reasonable grounds to have swayed Mr Ancell from the view held by him before the disciplinary hearings that he could not say which one of the two employees was responsible of the loss, to the decision that the Applicant alone was responsible, we are unanimous that the answer must be a negative one."
"In Monie .v. Coral Racing Ltd[1980] IRLR 464 the Court of Appeal upheld a finding by an Industrial Tribunal that a dismissal was fair when an employer who was unable to decide which of two particular employees was guilty of dishonesty, dismissed both of them."
"It appears not only from the Respondent's Notice of Appearance, but also from the evidence as a whole, that the Respondents had set themselves the task of going beyond the position held by the employer in Monie .v. Coral Racing Ltd and were determined to lay the blame upon one of these two individuals. The process by which the Respondents management came to select the Applicant as the guilty party has taken this dismissal outside the range of responses available to a reasonable employer in the circumstances of the case."
"54 ... All the matters considered and evaluated by Mr Ancell were reconsidered and re-evaluated by Mr Duffy, who endorsed Mr Ancell's conclusions. In addition, he considered a number of other points raised by the Applicant, and reasonably concluded that they did not take the matter any further.
"Could he reasonably have taken account of that point in favour of Mrs Sims or against Miss Savill?"
