"2 The applicant was a Post Office Delivery Officer, working for the Royal Mail in Bath, one of the largest delivery offices in the South West. He had no disciplinary record until 1997. Between November and June 1998, he was disciplined for three different incidents, the last two being related: (a) Following a disciplinary interview on the24 November 1997 , the applicant was given a suspended dismissal of 3 months. The allegations were that he had failed to safeguard a priority service item, and failed to carry out and adhere to the correct delivery procedure for the priority service item. The applicant appealed against that decision. The appeal was rejected on the26 January 1998 . (b) In the meantime, following another complaint, the applicant was given a further suspended dismissal for 2 years following a disciplinary hearing on the23 February 1998 , the allegation being that he had failed to carry out the correct re-direction procedure. The applicant appealed against that disciplinary penalty. The appeal was heard on the30 April 1998 and rejected. (c) The third matter concerned the intimidation of the customer who had complained about the re-direction of mail in the second incident. The applicant was suspended on the 19 May and warned not to go near the customer's address. The disciplinary interview was held on the 22 May. On the 15 June, following further enquiries, and having given the applicant further opportunity to put his concerns in writing, the applicant was dismissed with notice. The allegation was that the applicant had intimidated a customer by his unofficial action in approaching her regarding a previous complaint and by so doing, brought the Royal Mail into disrepute. He appealed against his dismissal. The appeal was rejected on the29 July 1998 ."
"31 Our task is then to say whether the respondent acted reasonably or not in treating that as a sufficient reason for dismissing the applicant. We take, as our starting point, the provisions ofSection 98(4) of the Employment Rights Act 1996 :- '98(4) 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.' In applying that provision to the facts of the case, we remind ourselves that it is not for us to stand in the shoes of this employer and decide what we would have done. Rather, we must decide whether the employer's decision to dismiss the applicant for the reason proved fell within the range of response of a reasonable employer. In deciding that issue, we have regard to these principles:- (i) Did the employer believe in the misconduct alleged? (ii) Was that belief based on reasonable grounds? (iii) Was there a proper enquiry and investigation into the facts of the case? (iv) Was the applicant given an opportunity to state his case and did the respondent take into account the applicant's explanations? (v) In all the circumstances, was dismissal a sanction open to a reasonable employer?"
"32 It must be stressed that we must decide those issues in the light of the knowledge available to the employers at the time. Many of the matters to which the applicant referred in evidence and cross-examination have been the result of his persistent enquiries over the months since he was dismissed. He has not accepted his dismissal, or the reasons for it, and has sought to prove his theory that there was a conspiracy against him. He has obtained letters from the person to whom the special delivery mail was sent; from the person to whom it was apparently delivered; from one of the Spencer's and so on. None of that material was available to the respondent. We reiterate, we judge the case in the light of the information known to the respondent at the time. We have to decide whether they acted reasonably in relying upon it."
