"... evidence as to decisions made by an employer in truly parallel circumstances may be sufficient to support an argument, in a particular case, that it was not reasonable on the part of the employer to visit the particular employee's conduct with the penalty of dismissal and that some lesser penalty would have been appropriate in the circumstances. Industrial Tribunals should scrutinise arguments based upon disparity with particular care and there will not be many cases in which the evidence supports the proposition that there are other cases which are truly similar, or sufficiently similar, to afford an adequate basis for argument. It is of the highest importance that flexibility should be retained and employers and Tribunals should not be encouraged to think that a tariff approach to industrial misconduct is appropriate."
"The requirement that employers must act consistently between all employees means that, before reaching a decision to dismiss, an employer should consider truly comparable cases of which he knew or ought reasonably to have known. The overriding principle must be, however, that each case must be considered on its own facts and with freedom to consider mitigating aspects. Not every case of leniency should be considered to be a deviation from declared policy."
"... the Industrial Tribunal had misdirected themselves in law, in not properly considering disparities... where employees guilty of gross misconduct had not been dismissed in other cases, on the ground that those cases had been dealt with by different people.
"The Industrial Tribunal had erred in finding that it was unfair to dismiss the respondent employee for having committed a deliberate fraud by overbooking an item under the appellant employers' payment-by-results scheme, in circumstances in which he had received a previous written final warning for a similar fraud. The Industrial Tribunal had substituted their own judgment of what was reasonable for that of the employer,... Dismissal of the respondent was an inevitable result of the repetition of an offence of dishonesty...
"15. Notwithstanding the Industrial Tribunal's finding that there was some inconsistency between the actions of the respondents in similar cases, the Tribunal found, therefore, that the matter of inconsistency although an important issue, is relevant within the duty of the employer to act reasonably within Section 57(3) of the 1978 Act. The Tribunal found that the respondents were unable to take into account the particular example put forward to the Tribunal because it had not been put to them either by the applicants themselves or their representative at the time of the hearings."
