"This appears to us to fundamentally miss the potential importance of the new evidence. Clearly if two pupils who were not present have made statements the investigator would need to establish why they had made those statements and this could have exposed evidence of a conspiracy instigated by some of the pupils (or even potentially members of staff) to fabricate the incident. We are bound to say that if the Claimant had been dismissed for that incident and if an unfair dismissal claim had come before this panel on those facts, it is likely that we would have concluded that the dismissal was unfair because of the Respondent's failure to properly investigate."
"If the matter had rested there then we repeat our view that if we were considering an Unfair Dismissal claim on those facts we may well conclude that the Respondents had not adequately investigated. Furthermore, if the matter had rested there we may well have concluded that a reasonable employer, considering the existence of this final written warning, may have found it appropriate and necessary to reopen the circumstances of the final written warning and complete the investigation to establish whether or not it had been correctly imposed. However, matters did not rest there."
"In these circumstances the final written warning having been given an appeal by way of complete rehearing having been offered and the Claimant apparently having decided not to pursue the appeal, we are satisfied that the principles set out above in the Tower Hamlets [ Tower Hamlets v Anthony[1989] IRLR 394 (CA)] and Stein [ Stein v Associated Dairies Ltd[1982] IRLR 447 (EAT)] cases are entirely applicable to this case. The Governors were entitled to proceed on the basis that there was an extant final written warning. They were under no obligation to reopen and further investigate it and the Tribunal has no legitimate purpose in doing so either. We are satisfied that that final written warning had been issued in good faith and that there were prima facie grounds for it."
"The case, however, turns on the validity of that final warning which was important in the employer's decision to dismiss the applicant and in the ET's upholding of that dismissal. It is arguable, at least in the context of Rule 3(10), that after a hearing with all the defects listed by the ET in paragraphs 26.3 to 26.6 of its determination, it was simply not open to a reasonable employer to issue a final warning, with all the potential consequences that that has. It was for the reasonable employer and not for the employee to correct those defects by further action. If the warning was in employment terms a nullity, failure to appeal against it could not improve it. The matter might be different if the employee's action in not appealing involved or implied an admission that the allegations made against her were true, but the terms of the NASUWT letter show that that was not the case. This approach, including a refusal to regard a failure to appeal as conclusive, would seem to be consistent with the approach of the EAT in Co-operative Retail Services v Lucas [1993]UKEAT/145/93 a determination that carries the authority of Mummery LJ when he was President of the EAT."
"We are, however, quite clear that on the evidence we have heard that no reasonable employer would have dealt with these matters by way of a final written warning, which is what in fact the Respondent did."
"If the warning was in employment terms a nullity, failure to appeal against could not improve it."
