"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 it knows 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 a declared policy." ( Proctor v British Gypsum Ltd[1992] IRLR 7 EAT, Wood P). (2) "
"We accept that analysis by Counsel for the Respondents of the potential relevance of arguments based on disparity. We should add, however, as Counsel has urged upon us, that industrial tribunals would be well to scrutinise arguments based upon disparity with particular care. It is only in the limited circumstances that we have indicated that the argument is likely to be relevant, 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 the argument. The danger of the argument is that a Tribunal may be led away from a proper consideration of the issues raised by [section 98 (4)]. The emphasis in that section is upon the particular circumstances of the individual employee's case. It would be most regrettable if Tribunals or employers were to be encouraged to adopt rules of thumb, or codes, for dealing with industrial relations problems and, in particular, issues arising when dismissal is being considered. It is of the highest importance that flexibility should be retained, and we hope that nothing that we say in the course of our judgment will encourage employers or Tribunals to think that a tariff approach to industrial misconduct is appropriate. One has only to consider for a moment the dangers of the tariff approach in other spheres of the law to realise how inappropriate it would be to import it into this particular legislation."
"All that those cases do is to state the common sense proposition that where two employees who have committed the same offence are treated differently by the employer, the industrial tribunal should ask whether the distinction made by the employer was within the band of reasonable responses open to the employer or so irrational that no reasonable employer could have made it. I have no reason to think that the industrial tribunal did not apply that common sense rule which hardly needs any authority."
