"5.10 Misconduct may give rise to criminal prosecution as well as disciplinary proceedings. If evidence of a possible criminal offence comes to light, or if an allegation of a criminal offence is made against a member of staff, it may be necessary to inform the police. However, subject to paragraphs 5.10 to 5.13 ... sic - this seems to be an error for 5.12 to 5.15 ) below, disciplinary action should generally be pursued even when criminal proceedings are possible or pending. […] 5.12 In cases where the police are investigating alleged or suspected misconduct of a potentially criminal nature, care must always be taken to ensure that disciplinary proceedings do not prejudice the criminal proceedings. […] 5.14 Disciplinary action must be postponed in circumstances where: an alleged or suspected criminal offence took place away from the workplace and the investigation initiated by the police; the investigating officer is unable to obtain evidence relating to any possible disciplinary charge pending the outcome of criminal investigations; or, the principle evidence comes from a prisoner and the nature of any possible disciplinary charge is identical to the criminal charge. 5.15 However, it will not normally be advisable to postpone disciplinary action in other circumstances."
"In our opinion, the question whether an employer has carried out such investigations as is reasonable in all the circumstances necessarily involves a consideration of any delays. In certain circumstances a delay in the conduct of the investigation might of itself render an otherwise fair dismissal unfair."
"23 […] No evidence was presented to us that the police had indicated that the Respondent should not embark on its internal enquiry whilst its proceedings were continuing nor was it apparently put to the Claimant that if he were to participate in an internal enquiry continuing at the same time as criminal proceedings he might feel it necessary to decline to make any comment on the ground that it may prejudice the outcome of the criminal proceedings. 24 Quite apart from the failure of the Respondent to comply with its own procedure, it seems to us that a delay of this magnitude is bound to run the risk that the evidence eventually unearthed by the investigator is going to be unreliable. That is going to be particularly so where, as in this case, one or other of the participants must have been telling lies. It will be necessary for the investigator to test the evidence of the principal participants by evidence from others and by timely interviews with the principal participants themselves. 25 We should say also that we recognise that one of the charges did involve the gathering of evidence from a prisoner but that did not apply to the charge that the claimant ultimately faced. We see no reason why the matters could not have been separated with an internal investigation proceeding straight away in relation to the allegation of planting of evidence whilst leaving the criminal proceedings as regards the other matter and the planting of evidence to take their course. 26 The Tribunal is less concerned about the delays within Governor Adebanjo's investigation. He appears not to have taken much action within the first three weeks of the four that he was originally allocated. 27 We have carefully considered the decision of the Employment Appeal Tribunal in A v B and we have considered, in particular, paragraphs 63 to 71 of that judgment. We regard the delay in this case, caused by the decision not to proceed with the disciplinary processes until completion of the criminal proceedings, as unacceptable. By his suspension, but in the absence of any disciplinary action, the Claimant was effectively denied the opportunity to gather evidence in support of his defence until a point when it was futile for him to do so. We note in particular that at paragraph 70 of the decision in A v B that the court held that the delays were so lengthy and the justification for them so limited in that case, that the Tribunal did err in concluding that they did not render the dismissal unfair. At paragraph 71 it is said that the Tribunal may have misdirected themselves by considering that the delays would only render the dismissal unfair if they could have been shown in some way to have affected the overall outcome of the hearing. 28 We are bound by the decision in A v B and, since we consider that the delays in this case were so lengthy and the justification for them unacceptable, we are of the view that we are bound to hold that this amounts to procedural unfairness sufficient to render the dismissal unfair. 29 We are, however, bound also to considersection 98A(2) of the Employment Rights Act 1996 . Has the Respondent shown, on the balance of probabilities, that it would still have dismissed the Claimant even if it had conducted the disciplinary investigation promptly after the events of March 2006? It is impossible for us to say that the same outcome would have resulted. We do not know what subtle difference might have emerged in the evidence of the principal participants and of the minor witnesses that may have played a part in the decision of the person who would than have held the disciplinary hearing. Our view (see below) about Governor Leader's belief is that he did not genuinely believe the Claimant to be guilty of the misconduct alleged. Had the investigation been undertaken when it should have been, the evidence might well have been stronger against the Claimant than it appears to have been but equally the evidence might have been weaker. We simply cannot say what the outcome would have been. The Respondent has not, on the balance of probabilities, proved that, even if it had conducted the disciplinary hearing much sooner, it would still have dismissed the Claimant. Accordingly, the dismissal is unfair for that reason."

"There was evidence from Officers 1 and Tester that the Claimant had proposed to them that they should plant evidence near to Prisoner B's cell. That evidence was, if it was genuinely believed, sufficient for Governor Leader to hold that the Claimant was guilty of the misconduct alleged."
"Given his acceptance of the Claimant's proposition that there was no logical reason for him to make the proposal to Officers 1 and Tester, it seems to us that there was no reason for Governor Leader to, as it were, "come down off the fence" and hold that the charges were proved. There was no real basis for him to do that and he ought, in the circumstances, given his earlier comments, and apparent findings, to have simply said that the case was not proved."
"Using this flawed and incomplete evidence, Governor Leader could not have reasonable grounds on which to base a belief, to the higher standard of proof required, that the Claimant had committed the alleged misconduct."
