"Despite Mr Hughes' denials I have no reason to doubt Mr Threlfall's statement and I have a belief, as Mr Holden did, that Mr Threlfall has told the truth and I therefore have a belief based on Mr Threlfall's evidence that Mr Hughes was involved in the wilful delay of mail."
"..... And they do not have regard to equity or the substantial merits of the case if they jump to conclusions which it would have been reasonable to postpone in all the circumstances until they had, per Arnold J in Burchell [i.e. British Home Stores Ltd v Burchell[1978] IRLR 379 ] "carried out as much investigation into the matter as was reasonable in all the circumstances of the case". That means that they must act reasonably in all the circumstances, and must make reasonable inquiries appropriate to the circumstances. If they form their belief hastily and act hastily upon it, without making the appropriate inquiries or giving the employee a fair opportunity to explain himself, their belief is not based on reasonable grounds and they are not acting reasonably."
"..... The applicant was suspected of "soaking" the mail and it was this which ultimately led to the dismissal. The basis for that, and the only basis for that is to be found in the allegations made by Mr Threlfall. Is that a sound basis for a reasonable employer to reach a conclusion to dismiss? Mr Holden, and indeed Mr Murphy, seem to have been very ready, indeed all too ready, to accept what Mr Threlfall had said, despite the continued denials of Mr Hughes throughout. He was an employee of 8 years' standing and, up to this point, had a good record insofar as conduct was concerned. An informer, and Mr Threlfall may properly be described as such, should be viewed with at least some degree of scepticism and clearly corroboration of what he says is desirable. In this case there was none whatsoever. The video showed nothing as to that. That should have had an effect upon the course of the investigation. Mr Threlfall had nothing to lose; he was facing criminal proceedings. Indeed, criminal proceedings were also instigated against the applicant but were rejected at the committal stage. ..... Our concern is with the quality of the enquiries which were made in what is, in reality, as we have already said, an informer case where someone "pointed the finger" after having themselves been accused and therefore, again as we have said, having absolutely nothing to lose. In such instances, an appeal by way of complete re-hearing could have offered a more satisfactory resolution of the matter."
"18 ..... To the extent that this refusal was based on Mrs Morgan's alleged absences from her workplace, we have no reason to think that the evidence on which Mr Duckworth based his decision was any better than that which we have heard. Virtually the only first-hand evidence on the point was that of Miss Hammond, evidence which in the circumstances ought not to have been preferred to that of Mrs Morgan. We do not think it reasonable for Mr Duckworth to come to his conclusion on the basis of such evidence."
"19 It is the last three sentences quoted above which in our judgement disclose an error of law on the part of the Industrial Tribunal. Notwithstanding the proper direction which they had given themselves, these sentences indicate that they were substituting their own evaluation of Miss Hammond as a witness for that of the employers, possibly misled by their own incorrect inference that Miss Hammond had been away from work on the Tuesday and part of the Wednesday and therefore was not a credible witness as to the absence of the appellant from her place of work. Since this was clearly a major plank in the Industrial Tribunal's finding that the appellant was unfairly dismissed, we agree with the unanimous view of the EAT that there was here an error of law on the part of the Industrial Tribunal which vitiates their decision."
