“Comments on Evidence 45. Evidence was heard on oath or affirmation from all witnesses. 46. All witnesses were straightforward, credible and consistent in their evidence. It was noted that Melanie Bowie is not operational and so do not have first-hand experience of injuries which could be sustained with appropriate use of force. 47. Much of what was relied upon by the claimants in respect of the unreasonable extent of the investigation had not been put to the respondent prior to their dismissals, or at appeal. Matters not put for consideration during the respondent’s internal proceedings could not be material to the reasonableness of the decision to dismiss. As stated during these proceedings, we must not substitute the employer’s decision but rather consider the reasonableness of that decision in the particular circumstances. 48. It is well established that ‘contemporary documents are always of the utmost importance’ (Onassis and Calogeropoulos v Vergottis[1968] 2 Lloyd’s Rep 403 , at para 431). Applying the above guidance, significant weight was attached to the position in relevant contemporaneous documents.”
