"3. The Law 3.1 In considering the question of whether there was a fair dismissal in this case, we had to apply the provisions ofSection 98 of the Employment Rights Act 1996 , including Section 98(4) which provides that:- 3.2 "the determination of the question whether the dismissal is fair or unfair (having regard to the reason shown by the employer) 3.3 (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 3.4 (b) shall be determined in accordance with equity and the substantial merits of the case." 3.5 In a conduct dismissal case, the tribunal has to consider whether the employer: (1) Genuinely believed the employee to be guilty of misconduct; (2) Had reasonable grounds for believing that the employee was guilty of that misconduct; and (3) Had carried out as much investigation as was reasonable at the time it held that belief, ( British Home Stores Limited v Burchell[1978] IRLR 379 ). 3.6 In the light of the answers to those questions the tribunal then proceeds to consider overall fairness as required by s 98(4) ERA 1996. 3.7 In determining fairness, an employment tribunal will not consider whether the employee actually was guilty of the misconduct, therefore, but whether the employer believed, and had reasonable grounds for believing, that the employee was guilty of the misconduct at the time. It is not, as such, necessary for the employer to prove misconduct was committed on the balance of probabilities. 3.8 It is also very well established law that we had to consider whether dismissal fell within the band of reasonable responses (available to a reasonable employer) in all the circumstances of the case. Our exercise does not permit the Employment Tribunal to substitute its own view of whether it would have dismissed at the time, but only whether dismissal fell within that band. For example, in London Ambulance Service NHS Trust v Small , the Court of Appeal reaffirmed that in unfair dismissal claims, the function of a tribunal is to review the fairness of the employer's decision, not to substitute its own view. 3.9 We also had to follow the approach in Sainsbury's Supermarkets Limited v Hitt EWCA 2002 Civ 1588, ICR 2003, 115 and decide whether the investigation conducted as at dismissal was within the band of reasonable approaches to an investigation of this nature and consider it objectively, not substitute our own view of the investigation that perhaps should or could have been conducted."
"4.11 Finally, it was necessary to look at the Claimant's disciplinary record. This was exemplary with no warnings, and good performance throughout. There was no evidence whatsoever of any use of bad language in the employment. To send an email of this nature would therefore be extremely out of character and again, pointed to it being unlikely that he would have done so."
