"Where the employer has fulfilled the requirements of subsection (1), the determination of the question whether the dismissal is fair or unfair (having regard to the reason shown by the employer) - (a) depends on whether in the circumstances (including the size and administrative resources of the employer's undertaking) the employer acted reasonably or unreasonably in treating it as a sufficient reason for dismissing the employee, and (b) shall be determined in accordance with equity and the substantial merits of the case."
"60. Serious allegations of criminal misbehaviour, at least where disputed, must always be the subject of the most careful investigation, always bearing in mind that the investigation is usually being conducted by laymen and not lawyers. Of course, even in the most serious of cases, it is unrealistic and quite inappropriate to require the safeguards of a criminal trial, but a careful and conscientious investigation of the facts is necessary and the investigator charged with carrying out the inquiries should focus no less on any potential evidence that may exculpate or at least point towards the innocence of the employee as he should on the evidence directed towards proving the charges against him. 61. This is particularly the case where, as is frequently the situation and was indeed the position here, the employee himself is suspended and has been denied the opportunity of being able to contact potentially relevant witnesses. Employees found to have committed a serious offence of a criminal nature may lose their reputation, their job and even the prospect of securing future employment in their chosen field, as in this case. In such circumstances, anything less than an even-handed approach to the process of investigation would not be reasonable in all the circumstances."
"81. … certain members of staff, who may have given relevant evidence were not interviewed at all … it is relevant to note that it is not said that they could not have had anything relevant to say, merely that by the time they might have been interviewed they would not be likely to remember anything, even if it was relevant. 82. Mr Pepperall (counsel for the Respondent) submitted that it is unlikely that they would have had anything material to add. He may well be right, but it seems to us that is not something one can assume … 83. Perhaps of greater significance is the fact that the statements which were taken, and may have been of some assistance to the Applicant, were not provided to him … there was some material in those statements which might have assisted the Appellant, had they been made available to him. 84. If an employer reasonably forms a view that certain evidence is immaterial and cannot assist the employee, then of course a failure to disclose that material will not necessarily render a dismissal unfair. Ultimately, fairness is a broad concept and must be considered in the round. 85. In this case the Tribunal took the view that the Appellant was not materially prejudice. We do not think they were entitled to reach that view in the light of admitted failure by the Respondent to make evidence available. They appear to have concluded that, even if the relevant evidence had been provided, it would not have affected the result. 86. If that is what they intended to say, then, in any event, they fell into error. It is no answer for an employer to say that even if the investigation had been reasonable it would have made no difference to the Decision …"
